Carpal tunnel Syndrome

🧾  Condition Snapshot

Carpal Tunnel Syndrome (CTS) is caused by compression of the median nerve as it passes through the carpal tunnel at the wrist. This results in sensory changes, motor weakness, and functional limitations, particularly affecting fine motor tasks and sustained hand use.

Common presentation includes numbness and tingling in digits 1–3, decreased grip strength, pain, and difficulty with repetitive or sustained hand activities.

👤 Occupational Profile Prompts

  • What meaningful activities require sustained or repetitive hand use?

  • What tasks are most limited by numbness, weakness, or discomfort?

  • How are symptoms impacting sleep or daily routines?

  • What environments or work demands are contributing to symptoms?

⚠️ Precautions

  • Avoid sustained wrist flexion or extension

  • Limit repetitive gripping or forceful hand use

  • Monitor for progressive weakness or thenar atrophy

  • Post-surgical: follow surgeon-specific protocols

🎯OT Considerations

  • Prioritize function over isolated strength training

  • Symptoms often worsen with repetition, positioning, and time

  • Address both task demands and environmental setup

  • Consider ergonomics and activity modification early

  • Night symptoms may significantly impact rest and recovery

🛠️ Intervention Considerations

Symptom Management

  • Neutral wrist positioning

  • Activity modification

  • Splinting (especially at night)

Function-Based Training

  • Task-specific hand use within tolerance

  • Gradual return to meaningful activities

  • Avoid aggravating patterns early

Ergonomic & Environmental Modification

  • Workstation adjustments

  • Tool adaptation (built-up handles, positioning)

  • Reduce sustained or awkward wrist positions

Education & Pacing

  • Activity pacing strategies

  • Symptom awareness and early modification

  • Avoid “pushing through” worsening symptoms

📊 Common Assessments

Phalen’s Test

  • Type: Screening (Special Test)

  • Why: Provokes median nerve compression symptoms

  • When: Suspected CTS; initial clinical screening

Tinel’s Sign

  • Type: Screening (Special Test)

  • Why: Identifies nerve irritation at the wrist

  • When: Early evaluation to support diagnosis

Semmes-Weinstein Monofilaments

  • Type: Impairment (Sensory)

  • Why: Assesses light touch and sensory deficits in median nerve distribution

  • When: Noting sensory changes or progression

Grip & Pinch Strength

  • Type: Impairment (Motor)

  • Why: Identifies weakness impacting functional hand use

  • When: Baseline and progress monitoring

QuickDASH

  • Type: Functional (Self-Report)

  • Why: Captures perceived difficulty with upper extremity tasks

  • When: Establishing baseline and tracking functional outcomes

📚 EBP Snapshot

  • Wrist splinting (especially at night) is effective for symptom management

  • Activity modification and ergonomic changes reduce symptom progression

  • Nerve gliding exercises may provide benefit in some cases

  • Early intervention improves functional outcomes

🧠 Clinical Anchor

Prioritize function and symptom management. Reduce irritation, support participation, and modify tasks to maintain meaningful hand use.
