Urazy powtarzalnego napięcia
Patofizjologia i mechanizm

Urazy powtarzalnego napięcia (RSI) to schorzenia układu mięśniowo-szkieletowego i nerwowego wynikające z powtarzalnych ruchów i przeciążenia tych samych struktur anatomicznych, głównie w obrębie kończyn górnych, szyi i ramion. Patofizjologia obejmuje kumulację mikrourazów prowadzących do zapalenia, zwyrodnienia (tendinoza), bliznowacenia, kompresji nerwów oraz zmęczenia mięśniowego z wyczerpaniem ATP. W zespole cieśni nadgarstka (CTS) ciśnienie w kanale nadgarstka przekraczające 30 mm Hg powoduje ucisk nerwu pośrodkowego. Wibracje narzędzi mechanicznych i czynniki psychospołeczne, takie jak stres i niskie zadowolenie z pracy, nasilają objawy. Przewlekłe RSI wiąże się z uwrażliwieniem ośrodkowym i neuroplastycznymi zmianami, co utrudnia leczenie i może prowadzić do trwałej niepełnosprawności. Tkanki zaangażowane w RSI mają słabe ukrwienie, co wydłuża czas regeneracji – odbudowa ścięgna może trwać około 100 dni, a rozpoczęcie regeneracji wymaga 2-3 tygodni odpoczynku.

Urazy powtarzalnego napięcia (RSI) – Patogeneza i mechanizm

Urazy powtarzalnego napięcia (ang. Repetitive Strain Injury, RSI) stanowią grupę schorzeń układu mięśniowo-szkieletowego i nerwowego spowodowanych powtarzalnymi ruchami i ciągłym obciążeniem tych samych struktur anatomicznych. Te urazy dotyczą głównie mięśni, ścięgien, nerwów oraz innych tkanek miękkich, najczęściej w obrębie kończyn górnych, szyi i ramion12. Patofizjologia RSI jest złożona i obejmuje szereg procesów prowadzących do mikrourazów tkanek, zapalenia i zwyrodnienia3.

Mechanizm powstawania mikrourazów tkankowych

Podstawowy mechanizm powstawania RSI polega na kumulacji mikrourazów tkanek, które powstają wskutek powtarzalnych ruchów. Gdy te same struktury anatomiczne są wielokrotnie angażowane w wykonywanie podobnych czynności, dochodzi do przeciążenia, które przekracza zdolność tkanek do samonaprawy4. W normalnych warunkach uszkodzenie strukturalne tkanki po urazie aktywuje kaskadę komórkową, która inicjuje proces zapalny i rozpoczyna naprawę tkanki. Jednak przy powtarzających się urazach dochodzi do wielokrotnych mikrourazów, które zakłócają normalny proces naprawczy5.

Z każdym powtórzeniem ruchu w tkankach powstają mikroskopijne rozdarcia, szczególnie w mięśniach i ścięgnach przedramienia, nadgarstka i palców. Uszkodzone mięśnie mają tendencję do kurczenia się, co zmniejsza zakres ruchu niezbędny do pracy bez obciążenia. Ponadto osłonki, które pokrywają delikatne ścięgna, tracą odpowiednie smarowanie z powodu braku czasu na odpoczynek, co prowadzi do tarcia między ścięgnem a osłonką, powodując ból6.

Zmiany patologiczne w tkankach miękkich

W przypadku przewlekłych RSI, skumulowane obciążenie może prowadzić do szeregu niekorzystnych zmian w tkankach:7

8

Te zmiany mogą prowadzić do zaburzenia ciągłości tkanki, podrażnienia biomechanicznego, bólu oraz zmian w typie i organizacji kolagenu w ścięgnach i więzadłach, co zmienia ich wytrzymałość, elastyczność i giętkość9.

Stadia mikrourazów powtarzalnych

Powtarzalne mikrourazy można podzielić na cztery stadia w oparciu o odpowiedź tkanek miękkich na uraz (bez uwzględnienia wtórnej, nieprawidłowej degradacji ośrodkowego układu nerwowego):10

  1. Stadium pierwsze: Uraz może wywołać zapalenie, ale nie wiąże się z patologicznymi zmianami w tkance
  2. Stadium drugie: Obserwuje się zmiany patologiczne, takie jak tendinoza (zwyrodnienie ścięgien)
  3. Stadium trzecie: Uraz wiąże się z uszkodzeniem strukturalnym (pęknięciem)
  4. Stadium czwarte: Widoczne są dodatkowe zmiany, takie jak kalcyfikacja kostna

11

Zmiany w ścięgnach i nerwach

Badania nad patofizjologią RSI wykazały, że w większości przypadków przewlekłych urazów ścięgien występuje tendinoza, czyli zwyrodnienie kolagenu, bez klinicznych lub histologicznych oznak odpowiedzi zapalnej12. Wbrew powszechnemu przekonaniu, w RSI białe krwinki są prawie nieobecne, a pod mikroskopem widoczne są raczej oznaki uszkodzenia i zwyrodnienia tkanki niż ostrego zapalenia13.

Ponadto powtarzalne napięcie i przeciążenie mogą prowadzić do kompresji nerwów przebiegających przez obszar objęty urazem, co jest częstą przyczyną bólu, mrowienia i drętwienia. Początkowy ból może być zlokalizowany w miejscu urazu, ale z czasem może promieniować wzdłuż kończyny14.

Mechanizmy kompresji nerwów i zaburzenia krążenia

Funkcja nerwów obwodowych może zostać zakłócona przez przeciążenie mechaniczne. Na przykład, w zespole cieśni nadgarstka (jednej z form RSI), badania wykazały, że określone pozycje przedramienia, nadgarstka i palców, umiarkowane obciążenie ręki oraz zewnętrzny nacisk na dłoń mogą zwiększyć ciśnienie w kanale nadgarstka do poziomów zagrażających zdrowiu nerwów15.

Przy ciągłym napięciu nerwowym sygnały uszkodzenia nerwów przechodzą do rdzenia kręgowego, gdzie uwrażliwiają sąsiednie nerwy, potencjalnie prowadząc do skurczów mięśni w danym obszarze lub stawie16. Niekorzystne napięcie pnia współczulnego może powodować zahamowanie dopływu krwi do nerwów, co przyczynia się do objawów RSI17.

Zmęczenie mięśniowe i wyczerpanie energetyczne

W mechanizmie RSI istotną rolę odgrywa również zmęczenie mięśniowe. Ciągły skurcz mięśni wynikający z długotrwałego statycznego obciążenia bez odpowiednich przerw może prowadzić do zmniejszenia lokalnego krążenia krwi i zmęczenia mięśni18. To z kolei powoduje wyczerpanie ATP (adenozynotrifosforanu) – związku energetycznego niezbędnego do prawidłowego funkcjonowania mięśni19.

Nadmierna siła, szczególnie w połączeniu z powtarzalnymi ruchami, nie pozwala na pełną regenerację mięśni między ruchami. Prowadzi to do zmęczenia mięśni, które nie mają czasu na odpoczynek między dwoma ruchami. W rezultacie wykonywanie tych samych czynności wymaga coraz większego wysiłku20.

Wpływ wibracji na rozwój RSI

Wibracje stanowią istotny czynnik w patogenezie RSI i występują w dwóch głównych typach:21

  1. Wibracje ręki/ramienia: Dotyczą osób obsługujących narzędzia mechaniczne, takie jak wiertarki, młoty pneumatyczne, pistolety pneumatyczne, piły łańcuchowe itp.
  2. Wibracje całego ciała: Występują u operatorów ciężkiego sprzętu, kierowców pojazdów ciężarowych itp. Ten rodzaj wibracji często przyczynia się do bólu dolnej części pleców.

22

Ciągła ekspozycja na wibrujące narzędzia lub sprzęt, często spotykana w branżach takich jak budownictwo i produkcja, stwarza ryzyko rozwoju RSI poprzez dodatkowe uszkodzenie tkanek23.

Rola czynników psychospołecznych

Czynniki psychospołeczne odgrywają istotną rolę w rozwoju RSI. Zwiększony stres psychologiczny może nasilać objawy RSI24. Reakcja organizmu na stres może prowadzić do zwiększonego napięcia mięśniowego, co dalej pogarsza stan RSI25.

Badania wykazały, że zadowolenie z pracy jest ważnym czynnikiem w rozwoju RSI. Stres związany z niskim poziomem satysfakcji z pracy może powodować fizjologiczne zmiany w organizmie26. Reakcje te obejmują zwiększoną aktywność mięśniową, która utrudnia dostarczanie składników odżywczych i usuwanie produktów przemiany materii27.

Inne reakcje na stres obejmują uwalnianie hormonów, które mogą dodatkowo zmniejszyć mikrokrążenie w pracujących mięśniach i podnieść poziom niektórych białek, co może zwiększyć prawdopodobieństwo reakcji zapalnej28.

Uwrażliwienie centralnego układu nerwowego

W przewlekłych przypadkach RSI może dojść do uwrażliwienia ośrodkowego, czyli zjawiska, w którym centralny układ nerwowy staje się nadmiernie wrażliwy na bodźce bólowe29. Niepokój i cierpienie związane z przewlekłym bólem mogą faktycznie zmienić neurologię, czyniąc pacjentów bardziej wrażliwymi na ból30.

Powtarzalne bolesne stymulacje mogą również powodować neuroplastyczne zmiany w rdzeniowych i nadrdzeniowych układach nocyceptywnych31. W ten sposób powtarzalne impulsy motoryczne i nocyceptywne stają się częścią tych samych programów motorycznych, które są odpowiedzialne za ruchy o wysokiej częstotliwości i uszkodzenia tkanek32. W wyniku tego ból RSI może być odczuwany jako odpowiedź związana z zadaniem, nawet po całkowitym wyleczeniu wszystkich urazów33.

Tworzenie się blizny tkankowej

Organizm w naturalny sposób tworzy tkankę bliznowatą, aby wyleczyć mikrourazy spowodowane napięciem przez powtarzalne czynności. Jednak jeśli tkanka bliznowata nie ulegnie samoistnie rozpadowi po wyleczeniu urazu, może wymagać ręcznego usunięcia34.

Wszystkie urazy, zarówno niedawne, jak i bardzo stare, są zapisane w układzie tkanki łącznej organizmu, czyli w powięzi35. Gdy dochodzi do urazu, powięź faktycznie zmienia się w momencie urazu i pozostaje bardziej napięta i ograniczona w celu wsparcia zranionego ciała36. W ten sposób tworzy się tkanka bliznowata po urazie, która nie rozciąga się już łatwo i równomiernie w całej warstwie powięzi37.

Patofizjologia specyficznych form RSI

Zespół cieśni nadgarstka

Zespół cieśni nadgarstka (CTS) rozwija się, gdy nerw pośrodkowy, który przebiega przez kanał nadgarstka, zostaje uciśnięty z powodu zwiększonego ciśnienia w tej ciasnej przestrzeni38. Anatomia kanału nadgarstka obejmuje kości i więzadło poprzeczne nadgarstka, a gdy wzrost ciśnienia przekracza 30 mm Hg, może doprowadzić do ucisku nerwu39.

Przy wykonywaniu powtarzalnych ruchów nadgarstka istnieje większe ryzyko, ponieważ te czynności mogą nasilić zapalenie ścięgien zginaczy, dodatkowo uciskając nerw pośrodkowy40. Powtarzalne zadania, takie jak pisanie na klawiaturze lub używanie narzędzi, mogą prowadzić do przewlekłego napięcia, skutkując objawami zespołu cieśni nadgarstka41.

Tendinopatie i tenosynowitis

Tendinopatia opisuje stan, gdy ścięgna, które łączą mięśnie z kośćmi lub innymi częściami ciała, ulegają uszkodzeniu42. Ścięgna są otoczone ochronną osłonką zwaną błoną maziową. Ta osłonka może ulec zapaleniu, powodując stan zwany tenosynovitis43.

Niektórzy badacze sugerują, że nadmierne używanie ścięgien poprzez powtarzalne obciążanie powoduje RSI. Zaproponowano cztery mechanizmy patologiczne dla zapalenia ścięgien:44

  • Zmniejszona elastyczność ścięgna
  • Tarcie między ścięgnem a pochewką ścięgna
  • Zmęczenie ścięgna
  • Mechanicznie wywołany lokalny wzrost temperatury

45

Zapalenie kaletki (bursitis)

Zapalenie kaletki (bursitis) występuje, gdy kaletka (mały, wypełniony płynem worek, który działa jak poduszka między kośćmi, ścięgnami, mięśniami i skórą) ulega zapaleniu. Dotknięty obszar może stać się opuchnięty i bolesny46.

Powtarzający się ruch może prowadzić do zapalenia torebek maziowych, które amortyzują i chronią stawy i otaczające je struktury, co znane jest jako zapalenie kaletki47. Ta choroba to zapalenie ścięgien, które łączą mięśnie z kośćmi. Powtarzanie tych samych ruchów ciała wywiera nacisk na ścięgna, powodując obrzęk i ból48.

Łokieć tenisisty i łokieć golfisty

Łokieć tenisisty, znany również jako zapalenie nadkłykcia bocznego, jest formą tendinozy, która dotyka ścięgna przyczepione do zewnętrznej strony łokcia49. RSI łokcia może wystąpić w wyniku każdej aktywności wiążącej się z powtarzającym się chwytaniem lub ruchami ramion50.

Z drugiej strony, łokieć golfisty (zapalenie nadkłykcia przyśrodkowego) dotyka wewnętrznej strony łokcia i jest również związany z powtarzalnymi ruchami51.

Czynniki ryzyka i mechanizmy rozwoju RSI

Czynniki ergonomiczne

Powtarzalny ruch jest podstawowym mechanizmem prowadzącym do RSI, ale inne czynniki ergonomiczne również przyczyniają się do rozwoju tych urazów:5253

  • Długotrwałe utrzymywanie niezręcznych lub nienaturalnych pozycji, które obciąża układ mięśniowo-szkieletowy, prowadząc do nierównowagi mięśniowej i bólu lub przeciążenia stawów
  • Forsowne wysiłki, szczególnie w połączeniu z powtarzalnymi działaniami, które zwiększają obciążenie tkanek, przyspieszając ich zużycie
  • Niewystarczające okresy odpoczynku i regeneracji między powtarzalnymi zadaniami, które uniemożliwiają organizmowi skuteczne naprawianie i regenerację tkanek
  • Stanowiska pracy pozbawione elementów ergonomicznych lub źle skonfigurowane, które mogą sprzyjać niezdrowym postawom i powtarzalnemu napięciu

54

Urazy spowodowane powtarzalnym napięciem to urazy części układu mięśniowo-szkieletowego lub nerwowego spowodowane powtarzalnym użyciem, wibracjami, kompresją lub długimi okresami w ustalonej pozycji55. Ogólny światowy wzrost od lat 70. RSI rąk, dłoni, szyi i ramion przypisuje się powszechnemu wykorzystywaniu w miejscu pracy urządzeń wymagających wprowadzania danych za pomocą klawiatury, takich jak maszyny do pisania i komputery, które wymagają długich okresów powtarzalnych ruchów w ustalonej postawie56.

Czynniki osobnicze

Wiek i płeć są ważnymi czynnikami ryzyka dla RSI. Ryzyko RSI wzrasta z wiekiem57. Poprzednie urazy lub schorzenia, takie jak uszkodzenie stożka rotatorów lub uraz nadgarstka, pleców lub barku, mogą również predysponować do RSI58.

Urazy powtarzalnego napięcia (RSI) mogą wynikać z poprzedniego, pozornie niezwiązanego i nierozwiązanego urazu. Historyczne urazy mogą zmienić sposób, w jaki poruszamy się w momencie urazu i później, ze względu na adaptacje tkanek59.

Powtarzalne ruchy i kumulacja mikrourazów

Urazy powtarzalnego napięcia wynikają z powtarzalnych i forsownych ruchów, niewygodnych pozycji oraz innych warunków związanych z pracą i zagrożeń ergonomicznych60. Pracownicy w określonych dziedzinach są narażeni na powtarzalne napięcia. Większość urazów zawodowych to zaburzenia mięśniowo-szkieletowe, a wiele z nich jest spowodowanych urazami kumulacyjnymi, a nie jednorazowym zdarzeniem61.

Każdy ruch lub czynność, którą często powtarzasz, może spowodować powtarzalny uraz. Dzieje się tak, gdy twoje ciało doświadcza tego samego rodzaju stresu i napięcia przez dłuższy czas62. RSI jest zwykle wynikiem długotrwałych powtórzeń ruchu bez odpowiedniego odpoczynku. Ruchy wykonywane w nieprawidłowej lub złej postawie, lub nieprawidłowe ustawienie zaangażowanych stawów, mogą również prowadzić do RSI63.

Dlaczego zmiany w tkankach zachodzą wolno

Zdolność tkanki do gojenia zależy od jej ukrwienia. Tkanki i struktury zaangażowane w urazy powtarzalnego napięcia (ścięgna, pochewki ścięgien, torebki, więzadła, nerwy) generalnie mają bardzo słabe ukrwienie, dlatego goją się bardzo wolno i słabo reagują na uraz64.

Według Khana i współpracowników, może upłynąć nawet dwa do trzech tygodni odpoczynku, zanim ścięgno nawet zacznie się odbudowywać, a sama odbudowa jest boleśnie powolna: około stu dni, aby komórki ścięgna wyprodukowały cząsteczki kolagenu, które stanowią większość ścięgna65.

Implikacje kliniczne dla leczenia RSI

Znaczenie wczesnej diagnozy i interwencji

Wczesna diagnoza jest kluczowa dla ograniczenia uszkodzeń w RSI66. Gdy po raz pierwszy zauważysz objawy RSI, już wyrządziłeś sobie znaczną szkodę. RSI może rozwijać się miesiącami, nawet latami, a możesz oczekiwać, że zajmie to co najmniej dwa razy dłużej, aby się wyleczyć67.

Ignorowanie urazów powtarzalnego napięcia (RSI) i zespołu cieśni nadgarstka (CTS) może prowadzić do poważnych, długotrwałych konsekwencji dla zdrowia. Jeśli nie zostaną leczone, możesz doświadczyć przewlekłego bólu i zapalenia, które wpływają na mięśnie, ścięgna i nerwy. Z czasem ryzykujesz nieodwracalne uszkodzenie, a to, co zaczyna się jako mniejszy problem, może przekształcić się w trwałą niepełnosprawność68.

Podróż od ostrego RSI do stadium przewlekłego może być stopniowa. Dlatego ważne jest rozpoznanie i natychmiastowe zajęcie się wczesnymi sygnałami ostrzegawczymi w fazie ostrej. Wczesna interwencja może zapobiec progresji do stadium przewlekłego, czyniąc zarządzanie bardziej efektywnym i potencjalnie unikając długoterminowej niepełnosprawności69.

Rola odpoczynku w leczeniu

Pierwszym krokiem w leczeniu RSI jest zatrzymanie czynności powodującej uraz. Odpoczynek od aktywności zatrzyma powtarzający się stres nakładany na ten obszar70. Zatrzymanie uszkodzeń spowodowanych powtarzalnym napięciem tak szybko, jak to możliwe, pomoże przyspieszyć powrót do zdrowia71.

Prawda jest nudna i prosta: odpoczynek jest potężnym lekarstwem na RSI, ale także nudnym i często spektakularnie niedogodnym, nawet zagrażającym pracy i karierze72. Jedną z rzeczy, które sprawiają, że odpoczynek jest szczególnie istotny dla urazów powtarzalnego napięcia, jest to, że istnieją dobre dowody na to, że zwyrodniałe struktury tkanki łącznej wymagają dużo czasu, aby się zregenerować73.

Multidyscyplinarne podejście do leczenia

Leczenie urazów powtarzalnego napięcia zależy od tego, co je powoduje i jak poważne są objawy. Najlepszym leczeniem jest modyfikacja lub ograniczenie aktywności, która spowodowała uraz, aby zapobiec dalszym uszkodzeniom74.

Urazy powtarzalnego napięcia są zazwyczaj łatwo leczone za pomocą terapii manualnej, ćwiczeń na receptę, modyfikacji zachowań i strategii zapobiegawczych75. Ogólnie rzecz biorąc, uraz powtarzalnego napięcia nie jest trwały, pod warunkiem, że uwzględni się mechanizmy urazu i wynikające z nich zmiany struktur tkanek miękkich76.

Skuteczna wczesna interwencja i przestrzeganie wszelkich udzielonych porad może znacznie skrócić czas powrotu do zdrowia77. Schorzenia te często wolno ustępują i wymagają systematycznego i ustrukturyzowanego postępowania fizjoterapeutycznego (przez doświadczonego fizjoterapeutę), zwykle w ścisłej współpracy z innymi członkami zespołu leczenia bólu, np. lekarzami ogólnymi i specjalistami od bólu. Zwykle wymagają one określonego planu leczenia i nie ustępują samoistnie, jeśli pozostawić je bez leczenia78.

Niestety, z czasem niewielki stan może przekształcić się w wyniszczający uraz, bez wielu ostrzeżeń. Dodatkowy stres w życiu, presja, aby pracować ciężej i dłużej lub robić mniej przerw, może sprawić, że objawy będą znacznie bardziej dotkliwe i długotrwałe79.

Neuroplastyczność i jej znaczenie w leczeniu RSI

Skupienie się tylko na bólu i objawach RSI może maskować szerszy problem. W ramach leczenia RSI często konieczne jest skupienie się nie tylko na miejscu bólu, ale także na ocenie funkcji całego ciała, aby określić, dlaczego napięcia uszkadzają ten obszar80.

Model neuroplastyczny CTLT (tolerancji obciążenia urazami kumulacyjnymi) wskazuje, że powtarzalne ruchowe i nocyceptywne impulsy stają się częścią tych samych programów motorycznych, odpowiedzialnych za ruchy o wysokiej częstotliwości i uszkodzenia tkanek81. W ten sposób ból RSI może być odczuwany jako odpowiedź związana z zadaniem, nawet po całkowitym wyleczeniu wszystkich urazów82.

Proces zwiększonej wrażliwości może prowadzić do bardziej czujnego systemu ochronnego, który wpływa na kontrolę motoryczną, aby napinać mięśnie w dotkniętym obszarze, chroniąc przed dalszym postrzegalnym urazem83. Leczenie często obejmuje ręczne zabiegi, takie jak masaż lub suche igłowanie, ale powinno również obejmować porady dotyczące adaptacji aktywności i rehabilitacji w celu odczulenia obszaru i uniknięcia dekondycjonowania i osłabienia obszaru poprzez unikanie bolesnych ruchów84.

U pacjentów z przewlekłymi RSI ładunek kumulacyjny może prowadzić do zmniejszonej perfuzji (dopływu krwi), zmniejszonej funkcji nerwów obwodowych, nadmiernego zapalenia tkanek, bliznowacenia, kompresji komórek, degradacji macierzy zewnątrzkomórkowej, utraty włókien mięśniowych i śmierci komórek. Te zmiany mogą prowadzić do nieciągłości tkanek, podrażnienia biomechanicznego, bólu i zmiany typu i organizacji kolagenu w ścięgnach i więzadłach, co zmienia wytrzymałość, podatność i elastyczność85.

    https://my.clevelandclinic.org/health/diseases/17424-repetitive-strain-injury
    A repetitive strain injury is damage to your muscles, tendons or nerves caused by repetitive motions and constant use. […] Repetitive strain injuries are caused by doing the same motion or activity repeatedly until it starts to hurt your body. […] Any motion or activity that you frequently repeat can cause a repeated strain injury. They happen after your body experiences the same kind of stress and strain over time. […] How repetitive strain injuries are treated depends on whats causing them, and how severe your symptoms are. The best treatment is to modify or reduce the activity that caused your injury to prevent further damage. […] Stopping the damage from repetitive strain as soon as possible will help speed up your recovery.

    Repetitive strain injuries (RSI) present an increasingly common challenge to clinicians. […] These injuries result from repetitive and forceful motions, awkward postures, and other work-related conditions and ergonomic hazards. […] Occupationally induced RSIs are generally costly, creating a strong incentive for physicians to become familiar with the symptoms, signs, and risk factors so that they can be diagnosed early and appropriate interventions facilitated.

    Repetitive Strain Injury (RSI), also known as Repetitive Stress Injury, is a condition that results from repetitive movements, overuse, or prolonged poor ergonomics. […] The pathophysiology of RSI involves a combination of mechanical, inflammatory, and microtraumatic processes. Repetitive movements or prolonged postures can cause microtrauma to the soft tissues, leading to inflammation and swelling. Over time, this can result in tissue degeneration, impaired blood flow, and changes in the structure and function of the affected tissues. […] With continued repetitive strain, the affected tissues may undergo fibrosis and the development of adhesions, further compromising their ability to function properly. Nerves in the affected area may also become compressed or irritated, leading to symptoms of numbness, tingling, or pain.

    Repetitive strain injury (RSI) is most commonly related to the overuse and strain on the muscles, tendons and soft tissues of the upper part of the body like the wrists, forearms, shoulders, elbows, back or neck. […] The cause of RSI lies in repetitive microscopic trauma that occurs due to strain on the muscles and joints. This repeated trauma at the microscopic level leads to tendonitis or inflammation of the tendons, tenosynovitis or inflammation of the tendons and synovial sleeve or sheath covering the muscles and tendons. […] The actual underlying mechanism that leads to inflammation is not clear. […] Common factors that lead to RSI deep within the muscles and tendons include: Fatigue of the muscles and ligaments, tendons and muscles due to over strain and stretching. […] Strain may lead to lack of blood supply and damage to the nerves. This is called ischemia.

    repetitive strain injury (RSI), any of a broad range of conditions affecting muscles, tendons, tendon sheaths, nerves, or joints that result particularly from excessive and forceful use. Strain, rapid movement, or constrained or constricted posture may be other causes. […] Normally, structural tissue damage post-injury activates a cellular cascade to mediate inflammation and to initiate tissue repair. However, repetitive injury results in repeated tissue microtrauma, which disrupts the normal repair process. In patients with chronic RSIs, cumulative loading can lead to reduced perfusion (blood supply), reduced function of peripheral nerves, excessive tissue inflammation, scarring, cell compression, extracellular matrix degradation, muscle fibre loss, and cell death. Those changes can lead to tissue discontinuity, biomechanical irritation, pain, and change in the type and organization of the collagen in tendons and ligaments that alters strength, compliance, and flexibility.
  • #6 Repetitive Strain Injury
    https://web.eecs.umich.edu/~cscott/rsi.html
    Repetitive strain injury (RSI) is defined as a cumulative trauma disorder (CTD) stemming from prolonged repetitive, forceful, or awkward hand movements. The result is damage to muscles, tendons, and nerves of the neck, shoulder, forearm, and hand, which can cause pain, weakness, numbness, or impairment of motor control. […] Fine hand movements, repeated hour after hour, day after day, thousands upon thousands of times, eventually strain the muscles and tendons of the forearms, wrists, and fingers, causing microscopic tears. Injured muscles tend to contract, decreasing the range of motion necessary for stress free work. The sheaths that cover delicate tendons run out of lubrication because they aren’t given time to rest, so tendon and sheath chafe, resulting in pain. Due to this abrasion, tendons become inflamed, and begin to pinch neighboring nerves. This can result in numbness, tingling, or hypersensitivity to touch. Unless this cycle is interrupted, it repeats itself over and over, and a long-term, chronic problem results.

    Repetitive microtrauma can be classified into four stages based on the soft tissue response to injury (without consideration of secondary, aberrant central nervous system degradation). In stage one, the injury may induce inflammation, but it is not associated with pathological alterations in the tissue. In stage two, pathological alterations, such as tendinosis, are observed. In stage three, the injury is associated with structural failure (rupture). In stage four, additional changes are seen, such as osseous (bony) calcification.

[…] In RSI, white blood cells are barely present, and what you see under the microscope instead is shabbiness. Signs of tissue failure and degeneration. […] Numerous investigators worldwide have shown that the pathology underlying these conditions is tendonosis or collagen degeneration. […] Tendinosis is tendon degeneration without clinical or histological signs of an inflammatory response. It appears that tendinosis is the major, and perhaps the only clinically relevant chronic tendon lesion. […] The imagery of anatomy over-heating with use, like a poorly oiled machine, is so compelling and mentally comfortable that it is virtually impossible, at first, for most people to imagine tendinitis without inflammation. But not all repetitive strain injuries are tendinitises, and this osis business doesn’t just apply to tendons. Other tissues involved in RSIs are also generally lacking in inflammation, but are degenerating and struggling to adapt to stress in similar ways.

    https://www.sportinjuryspecialist.com/injuries/repetitive-strain-injury
    An RSI can occur in any muscle, tendon or joint that is impacted by a repetitive stress, although it is most commonly found in the shoulder, elbow or wrist. […] Initially pain may be felt only during an activity and stopping the movement may bring relief. Over time this discomfort carries into rest time as well. With prolonged use and lack of treatment the pain may become severe, even crippling. […] Compression of the nerves and or blood vessels passing through the injury site is the common causes of the pain, tingling and numbness. The pain usually starts out localized to the site of the injury but over time may radiate away from the site along the extremity.

    Some researchers have suggested that overuse of tendons by repetitive loading causes repetitive strain injury. Four pathological mechanisms have been suggested for tendonitis: decreased elasticity of the tendon; friction between tendon and tendon sheath; tendon fatigue; and mechanically-induced local temperature increase. […] The function of peripheral nerves can be disrupted by mechanical overload. In carpal tunnel syndrome, for example, studies showed that specific forearm, wrist, and finger postures, moderate hand loads, and external pressure on the palm can increase carpal tunnel pressure (at least temporarily) to levels at which nerve health is threatened.

    Repetitive strain injury (RSI) refers to musculoskeletal disorders caused by repetitive movements over time. Common RSIs include carpal tunnel syndrome and tendinitis. RSIs develop due to ergonomic and psychosocial stressors and cause pain, numbness, and functional limitations. […] The origin and development of RSIs, however, are multifactorial and controversial. Ergonomic stressors such as repetitive and forceful motions have been implicated, as have psychosocial factors. […] Several hypotheses for the pathophysiology of repetitive strain injury exist, but none has been strongly supported by scientific evidence. Despite initial distal presentation, this disorder seems to be a diffuse neuromuscular illness. Mechanical (elastic deformation of connective tissue due to increased pressure within muscles) and physiological (electrochemical and metabolic imbalances) reactions might cause damage to muscle tissue and lead to complaints of strain. Continuous contraction of muscles from long-term static load with insufficient breaks could result in reduced local blood circulation and muscle fatigue.

    https://patient.info/bones-joints-muscles/tendinopathy-and-tenosynovitis-tendinosis/repetitive-strain-injury
    Repetitive strain injury (RSI) is a condition where pain and other symptoms occur in an area of the body which has done repetitive tasks (often the arms, wrists or hands). Repetitive strain means strain related to actions which are frequently repeated. […] The term repetitive strain injury (RSI) is used to describe a range of painful conditions of the muscles, tendons and other soft tissues. It is mainly caused by repetitive use of part of the body. […] The main cause is frequent and repetitive movements of the same part of the body – for example, typing, using a computer mouse a lot, etc. Other risk factors may contribute, such as poor posture whilst doing the movement, using excessive force whilst doing the movement and not having enough breaks from the task. […] However, the precise reason why repetitive strain injury develops is not clear. In many cases there is no swelling or inflammation and there are no other obvious problems which develop in the muscles and tendons, and yet symptoms develop. […] Research suggests that psychosocial workplace factors (which usually means stress at work) can also contribute to RSI. It may be that stress increases muscle tension and/or affects how the body feels pain in general.

[…] While, at face value, this may seem illogical, there are plausible mechanisms which may explain this. These primarily relate to the bodys response to stress a situation which can certainly occur as the result of decreased levels of satisfaction with work. […] The increased muscular activity also impedes the delivery of nutrients and the removal of waste products. […] Other responses to stress include the release of hormones which can further reduce the bodys microcirculation in the working muscles and raise the levels of certain proteins. This can increase the likelihood of an inflammatory response. In combination, these effects result in physical changes which may manifest as pain and discomfort.

    A repetitive strain injury, or repetitive motion injury, is a condition that results from repeating the same movement during physical activities, like sports or job-related tasks. Repetitive motion can cause injury to your muscles, nerves, and tendons. […] While regular physical activity is vital for our joint (and overall) health, excessive repetitive motion may be harmful to our bodies. Too much repetition, particularly with unnatural movements or those involving strong forces, can wear down cartilage, tighten muscles, and reduce flexibility. This increases your risk of chronic pain or strain. […] Actions that contribute to developing a repetitive strain injury include performing the same motion over and over for extended periods. […] Repetitive motion can lead to inflammation of the fluid-filled sacs that cushion and protect your joints and surrounding structures, also known as bursitis.

    Repetitive strain injury (RSI), also known as Cumulative Trauma Disorder (CTD), occupational overuse syndrome, non-specific arm pain or work related upper limb disorder (WRULD), any joint pain that is believed to be caused by chronic misuse of these body parts, for instance, while using a computer on the job. Conditions such as RSI tend to be associated with both physical and psychosocial stressors. […] The term “repetitive strain injury” is most commonly used to refer to patients in whom there is no discrete, objective, pathophysiology that corresponds with the pain complaints. It may also be used as an umbrella term incorporating other discrete diagnoses that have (intuitively but often without proof) been associated with activity-related arm pain such as Carpal tunnel syndrome, Cubital tunnel syndrome, Thoracic Outlet Syndrome, DeQuervain’s syndrome, Stenosing tenosynovitis/Trigger finger/thumb, Intersection syndrome, Golfer’s elbow (medial epicondylosis), Tennis elbow (lateral epicondylosis), and Focal dystonia. […] Although Tendinitis and Tenosynovitis are discrete pathophysiological processes, one must be careful because they are also terms that doctors often use to refer to non-specific or medically unexplained pain, which they theorize may be caused by the aforementioned processes.

    Repetitive Strain Injury (RSI) also called repetitive motion injury is a musculoskeletal disorder resulting from prolonged and repetitive movements, commonly associated with activities like typing, gaming, or assembly line work. The mechanism of RSI development revolves around the consistent stress and strain imposed on muscles, tendons, and nerves. Over time, these tissues undergo micro-traumas due to repetitive actions, leading to inflammation, swelling, and tissue damage. […] RSI arises from a combination of factors, predominantly stemming from repetitive tasks and suboptimal ergonomic practices. […] The repetition leads to overuse injuries, where tissues are subjected to prolonged stress without adequate time to recover. The cumulative effect of repetitive movements gradually weakens these structures, making them more prone to injury and RSI symptoms.

    Repetitive strain injury (RSI) is not a specific injury, but instead a loose grouping of similar injuries. These injuries are also called repetitive stress injuries, cumulative trauma disorder (CTD), repetitive motion disorders, and overuse syndromes. These are soft tissue injuries associated with long-term repetitive stress on an area of the body. […] Repetitive strain injuries are usually a result of prolonged repetitions of a movement without adequate rest. […] An overload of stress on muscles, tendons or joints over a period of time without adequate rest may lead to RSI. Movements done in an incorrect or poor posture, or misalignment of the joints involved can also lead to an RSI. […] A repetitive strain injury can occur in any muscle, tendon or joint that is impacted by a repetitive stress, although it is most commonly found in the shoulder, elbow and wrist.

    Repetitive strain injury (RSI) is a term used to describe a broad range of symptoms caused by the repeated movement of a particular part of the body. […] The biggest problem for both RSI sufferers and their employers is that it almost always tends to start as a minor ache. This is largely because it can affect nerves, muscles, tendons, tendon sheets, bones and joints, one at a time, or in combination. […] When looking for an explanation as to why this occurs, two factors need to be taken into account. The first is that the ability for a tissue to heal is dependent upon its blood supply. The tissues and structures involved in Repetitive Strain Injuries (tendons, tendon sheaths, capsules, ligaments, nerves) generally have very poor blood supplies, therefore they heal very slowly and respond poorly to injury.

    According to Khan et al., it may take as much as two to three weeks of rest before a tendon even begins to start rebuilding, and then the rebuilding itself is achingly slow: about a hundred days for the tendon cells to produce the collagen molecules that make up the bulk of a tendon. […] People have an odd tendency even after a lot of suffering to act like repetitive strain injuries are relatively minor injuries that should get better if they take it easy. […] The coup de grace is that all the anxiety and suffering can actually change neurology, making patients more sensitive to pain. This is the phenomenon of central sensitization. […] And it gets even worse. Everything I’ve written here so far suggests that sensitization can be a complication of an injury. But what if you were sensitized to begin with? […] Never bet against neurology. Its probably a much larger factor in RSI than has yet been fully appreciated by anyone.

    Repetitive strain injury (RSI) is a controversial topic not because it doesn’t exist but because it is hard to diagnose with the existing technologies we have. Firstly, the name repetitive strain injury describes the mechanism of how an injury occurs but doesn’t give any information regarding what structures are actually painful. […] In reality repetitive strain injury may involve: Muscle, Joint, Nerve irritation, Combinations of the above. […] The first priority with repetitive strain is to identify what structures are involved and which tissues are producing the majority of symptoms. Once that is determined a treatment plan can be devised to reduce the sensitivity in the irritated structures. […] These conditions are often slow to resolve and need a systematic and structured physiotherapy management (by an experienced physiotherapist) usually in close liaison with other members of the pain management team e.g. General Practitioners and Pain Specialists.

    https://www.fitforgym.co.uk/blog/repetitive-strain-injuries-rsi
    The underlying cause common to all RSI-type conditions is damage to muscles and tendons (and the nerves that run through them) through repeated micro-trauma. Whenever muscles are used, tiny tears can occur in muscle tissue. The local area becomes inflamed for a short time as the body attempts to repair the damage. […] Nerves are also damaged by RSI. Tingling feeling, numbness and pain are caused by the compression of nerves. Nerves that run alongside the damaged muscle or tendon tissue can become sensitised by the inflammatory chemical produced due to the damage of overstrain myofascial tissue. This process of sensitisation only serves to make the symptoms harder to treat and slower to resolve. […] Unfortunately, over time a minor condition can turn into a crippling injury with little warning. Extra stress in life, pressure to work harder and longer or take fewer breaks can make the symptoms much more severe and long-term.

[…] Postural alterations can cause great injury over time, these types of RSI can be so in depth that they affect the very structure of the spine. I can also lead to arthritic changes or degeneration of the spine. […] Treatment for RSI can be quite successful. While it is important to address the location of the pain, it is equally important to assess the function of the entire body to determine the reason why stresses are injuring this area. […] A complete examination taking into account neurological, orthopaedic and postural factors leads to a complete diagnosis identifying the cause of the injury and its mechanism. When the cause of the injury is identified, the result of the treatment is more complete and chances of reoccurence decrease.

    repetitive strain injury (RSI), any of a broad range of conditions affecting muscles, tendons, tendon sheaths, nerves, or joints that result particularly from excessive and forceful use. Strain, rapid movement, or constrained or constricted posture may be other causes. […] Normally, structural tissue damage post-injury activates a cellular cascade to mediate inflammation and to initiate tissue repair. However, repetitive injury results in repeated tissue microtrauma, which disrupts the normal repair process. In patients with chronic RSIs, cumulative loading can lead to reduced perfusion (blood supply), reduced function of peripheral nerves, excessive tissue inflammation, scarring, cell compression, extracellular matrix degradation, muscle fibre loss, and cell death. Those changes can lead to tissue discontinuity, biomechanical irritation, pain, and change in the type and organization of the collagen in tendons and ligaments that alters strength, compliance, and flexibility.
