Treatment of Repetitive Strain Injury (RSI)
For RSI, immediately reduce or cease the causative activity, apply ice and rest in the acute phase, use NSAIDs for pain control, and begin early progressive exercise therapy focusing on stretching, strengthening, and ergonomic modifications to prevent recurrence.
Immediate Management
- The most critical intervention is early recognition of symptoms and immediate reduction or cessation of the causative activity 1
- Apply ice packs to affected areas for pain and inflammation control 2
- Rest the affected tissues during the acute inflammatory phase 3, 4
- NSAIDs (oral or topical) are effective for short-term pain relief and reducing inflammation 3, 2
- Local anesthetic-corticosteroid injections can provide prompt temporary pain relief when conservative measures are insufficient 2
Conservative Treatment Approach
Conservative treatment is usually effective but may take weeks to months to resolve 3:
- Rest: Temporary cessation or significant reduction of the repetitive activity causing injury 3, 4
- Ice or heat application: Use based on acute versus chronic phase 3, 2
- Compression: May help reduce swelling in acute phase 4
- Anti-inflammatory medications: NSAIDs or topical pain-relief agents 3, 2
- Massage: Can alleviate discomfort and improve tissue flexibility 2
Rehabilitation and Exercise Therapy
Pain relief must be achieved before patients can follow through with rehabilitation efforts 2:
- Stretching exercises: Restore flexibility to affected muscles and tendons 1, 2
- Strengthening exercises: Progressive resistance training once acute pain subsides 1, 4, 2
- Postural correction: Address postural deviations that contribute to RSI pathogenesis 2, 5
- Physical therapy should be initiated as pain and swelling subside 4
Ergonomic and Workplace Modifications
Workplace modifications are essential to prevent reinjury after return to work 3:
- Eliminate aggravating factors including improper posture and inadequate ergonomic setup 2
- Implement joint-protection measures 2
- Address contributory habits such as jaw or hand clenching 2
- For computer users, correct workstation ergonomics and keyboard positioning 5
Specific RSI Conditions and Their Management
Common RSI manifestations include 3, 2:
- Carpal tunnel syndrome: Wrist splinting, activity modification, NSAIDs, and potentially corticosteroid injection 2
- Trigger finger: Rest, NSAIDs, and corticosteroid injection if conservative measures fail 2
- Epicondylitis (tennis elbow): Ice, NSAIDs, stretching, and strengthening exercises 2
- Shoulder impingement syndrome: Rest, NSAIDs, and physical therapy focusing on rotator cuff strengthening 2
- Thoracic outlet syndrome: Postural correction and specific stretching exercises 3, 2
- Cervical and tension neck syndrome: Ergonomic modifications and neck-specific exercises 3
Prevention Strategies
Prevention is more effective than treatment 1:
- Adequate warm-up before intense or repetitive activities 4
- Avoid excessive fatigue during repetitive tasks 4
- Good nutrition and hydration 1
- Regular rest breaks during repetitive activities 1
- Early recognition of onset symptoms 1
Common Pitfalls to Avoid
- Continuing the causative activity despite symptoms leads to prolonged recovery and potential chronic disability 1
- Delaying treatment allows microtrauma to accumulate, worsening tissue damage 2
- Attempting rehabilitation exercises before achieving adequate pain control results in poor compliance 2
- Ignoring ergonomic factors and postural issues leads to recurrence after return to work 2, 5
- Failing to consider psychosocial factors in cases of persistent disability 2
- Not ruling out systemic disorders (rheumatologic diseases) that may mimic RSI 3
When to Consider Advanced Intervention
- Persistent disability despite 6-8 weeks of conservative treatment warrants consideration of psychosocial factors or alternative diagnoses 2
- Severe cases with significant functional impairment may require multidisciplinary group intervention including manual therapy 5
- Surgical intervention is rarely needed but may be considered for specific conditions like severe carpal tunnel syndrome unresponsive to conservative care 2
