Trigger Finger Exercise Recommendations
For trigger finger, therapeutic exercises including stretching, active range-of-motion exercises, and manual techniques should be implemented, though they are less effective than corticosteroid injection for initial symptom relief but may help prevent recurrence.
Evidence-Based Exercise Protocol
Specific exercises to implement include:
- Stretching exercises for wrist flexors and extensors should be performed regularly, as these improve functionality and reduce pain in hands and wrists 1
- Active range-of-motion exercises focusing on gentle finger flexion and extension movements help restore normal tendon gliding 1
- Manual lymph drainage techniques can reduce swelling around the affected flexor tendon sheath 1
- Strengthening exercises should be gradually introduced once acute symptoms improve to restore grip strength 2
Implementation Strategy
The exercise program should follow this approach:
- Begin with gentle stretching and range-of-motion exercises, avoiding forceful movements that trigger locking 1
- Progress to strengthening exercises only after triggering symptoms have substantially improved 3
- Exercises should be supervised initially by a physical or occupational therapist to ensure proper technique 1
- Continue exercises regularly and long-term, as benefits diminish during follow-up periods (up to 12 months) without ongoing therapy 1
Comparative Effectiveness
Important caveats about exercise efficacy:
- Physiotherapy alone has a 68.6% success rate at 3 months for mild trigger fingers, compared to 97.4% for corticosteroid injection 4
- Patients treated with physiotherapy have lower pain scores, slower recovery, and weaker grip strength initially compared to injection 4
- However, physiotherapy may have a role in preventing recurrence, as patients who successfully respond to exercises show no recurrence of pain or triggering at 6 months, possibly due to awareness and ability to self-treat early symptoms 4
Adjunctive Physical Therapy Modalities
Beyond exercises, consider:
- Extracorporeal shock wave therapy (ESWT) is effective and safe for conservative management, reducing pain and trigger severity while improving functional level and quality of life 5
- Ultrasound therapy has proven useful to prevent recurrence of trigger finger symptoms 5
- Biofeedback techniques can be incorporated to improve exercise performance 1
Splinting Combined with Exercise
Splinting should be considered alongside exercises:
- Splint the metacarpophalangeal joint at 10-15 degrees of flexion for 3-9 weeks (average 6 weeks) 6
- Splinting alone has a 66% success rate, with 50% success for thumbs and 70% for fingers 6
- The combination of splinting plus steroid injection offers no additional benefit over either treatment alone 7
- Patients with marked triggering, symptoms exceeding 6 months, or multiple involved digits have higher failure rates with conservative treatment 6
Clinical Algorithm
Recommended treatment sequence:
- For mild trigger fingers (mild crepitus, uneven movements, actively correctable triggering): Start with splinting plus exercises for 6 weeks 6, 4
- If unsuccessful after 6 weeks: Proceed to corticosteroid injection, which cures 88% of splinting failures 6
- For moderate-to-severe triggering: Consider corticosteroid injection as first-line treatment given superior initial outcomes 4
- After successful treatment: Continue maintenance exercises to prevent recurrence 4
- If injection fails: Surgical release is indicated 6
Key Pitfalls to Avoid
- Do not rely solely on exercises for moderate-to-severe triggering, as success rates are significantly lower than injection 4
- Avoid discontinuing exercises after symptom resolution, as benefits are not sustained without ongoing practice 1
- Do not use forceful stretching or strengthening during acute triggering episodes, as this may worsen symptoms 1
- Recognize that patients with symptoms exceeding 6 months have poorer outcomes with conservative treatment and may require earlier surgical intervention 6
