Comprehensive Approach to Wrist & Nerve Rehabilitation
Protocol design is generalized and practical. Electrotherapy modalities are utilized strictly as adjuncts when they contribute to symptom modulation and comfort—never as standalone or primary curative interventions. Long-term resolution relies on pressure relief, neutral immobilization, neurodynamics, and graded loading.
Our clinic provides thorough clinical evaluation and targeted treatment pathways for both nerve entrapments and tendon sheath inflammation, ensuring precise diagnosis and effective recovery options tailored to your needs.
Symptoms of Carpal Tunnel & De Quervain's
Do not ignore these physical red flags associated with median nerve compression and thumb tendon inflammation:
Finger Numbness & Tingling
Numbness and pins-and-needles in the thumb, index, middle, and radial half of ring finger, often worsening at night (Carpal Tunnel).
Thumb-Side Wrist Pain
Sharp pain near the base of the thumb when gripping, pinching, or turning the wrist (De Quervain's).
Catching & Snapping
A catching, snapping, or squeaking sensation when moving the thumb.
Grip & Pinch Weakness
Difficulty holding coffee cups, opening jars, or dropping objects due to hand coordination loss and thenar fatigue.
What Causes Carpal Tunnel & De Quervain's?
Nerve entrapment and tendon sheath friction stem from repetitive manual load and anatomical compression:
- Median Nerve Compression: Swelling inside the narrow carpal tunnel pinching the median nerve under the transverse carpal ligament.
- Thumb Tendon Friction: Thickening of the synovial sheath around the Abductor Pollicis Longus and Extensor Pollicis Brevis tendons (De Quervain's).
- Repetitive Hand Movements: Extensive keyboard typing, assembly work, gaming, or frequent tool handling.
- Hormonal & Fluid Shifts: Pregnancy-related fluid retention or tissue imbalances predisposing to internal wrist swelling.
Treatment Strategy & Management Options
Managing hand and wrist conditions involves structured non-surgical phases ranging from splinting and neurodynamics to targeted loading and progressive recovery:
Splinting & Protection
Neutral wrist splinting (0°–5° extension) prescribed primarily during sleep to reduce intracarpal pressure, along with avoiding provocative end-range wrist motions.
Mobility & Strengthening
Gentle ROM exercises, median nerve sliders, systematic tendon glides, and progressive forearm/wrist resistance exercises once resting irritability subsides.
How Carpal Tunnel & De Quervain's Are Diagnosed
Our structured 4-tier clinical diagnostic protocol evaluates over 50 specific clinical and physical evaluation parameters for precise median nerve and thumb tendon diagnosis.
1. History, Trauma & Paresthesia Audit
Complete breakdown of nocturnal numbness, typing strain, thumb pinch pain, and drop attacks.
- Nocturnal Hand Numbness: Tracking waking up at night with dead or tingling fingers (classic carpal tunnel sign).
- Thumb-Side Pinch Pain: Documenting sharp pain near the base of the thumb when lifting or turning keys (De Quervain's).
- Keyboard & Mouse Volume: Auditing daily typing hours and wrist positioning.
- Hand Drop Attacks: Noting sudden loss of grip causing items to drop unexpectedly.
- Pregnancy or Thyroid History: Screening hormonal shifts predisposing to fluid retention.
- New Mother / Child Care Load: Inquiring about repetitive lifting of infants (infant caretaker's thumb).
- Medication Efficacy Review: Documenting response to anti-inflammatory drugs or night splints.
- Visual Analog Scale (VAS): Recording numbness, tingling, and pinch pain scores (0-10 scale).
- Baseline Boston Carpal Tunnel Questionnaire: Measuring symptom severity and functional status.
- Driving Tolerance: Assessing hand numbness when holding steering wheel.
- Fine Motor Impairment: Evaluating difficulty buttoning shirts or tying shoes.
- Previous Wrist Fracture History: Screening past trauma altering tunnel geometry.
- Symptom Duration: Acute vs chronic insidious onset of hand weakness.
- Bilateral Involvement Check: Assessing if both hands are affected.
2. Nerve vs Tendon vs Cervical Differential
Differentiating carpal tunnel median neuropathy and de Quervain's tenosynovitis from C6 cervical radiculopathy and basal joint arthritis.
- Carpal Tunnel vs C6 Cervical Radiculopathy: Differentiating wrist median nerve compression from neck disc herniations referring arm/hand numbness.
- De Quervain's vs Thumb CMC Arthritis: Differentiating first dorsal compartment tenosynovitis from basal thumb joint arthritis.
- Pronator Teres Syndrome Screen: Differentiating proximal median nerve entrapment in forearm from wrist carpal tunnel.
- Intersection Syndrome Screening: Differentiating dorsal forearm pain proximal to wrist.
- Ulnar Neuropathy (Guyon's Canal) Rule-Out: Screening pinky-side hand numbness.
- Complete Neurological & Vascular Examination: Confirming normal two-point discrimination and radial pulse.
- Diabetic Peripheral Neuropathy Screen: Ruling out generalized systemic nerve involvement.
- Thyroid Disorder Correlation: Screening hypothyroidism associations with carpal tunnel.
- Gout / Crystal Deposition Screen: Ruling out inflammatory wrist crystal arthropathy.
- Tendon Laceration Rule-Out: Assessing acute tendon integrity after trauma.
- Infection Screening: Ruling out hand felon or tenosynovitis emergencies.
- Reflex & Strength Correlation: Matching clinical findings with nerve map.
- Clinical Synthesis: Integrating all physical and history data.
3. Physical Exam & Special Tests
Phalen's test, Tinel's sign at wrist, Finkelstein's test, two-point discrimination, and thenar atrophy assessment.
- Phalen’s Test: Holding wrists flexed together for 60 seconds reproducing median nerve numbness.
- Tinel’s Sign at Wrist: Lightly percussing over carpal tunnel reproducing tingling in thumb/index/middle fingers.
- Finkelstein’s Test: Thumb tucked inside closed fist with wrist deviated toward pinky, reproducing sharp radial wrist pain (De Quervain's).
- Eichhoff’s Test: Modified thumb-in-fist test for first dorsal compartment irritation.
- Thenar Atrophy Inspection: Checking for muscle wasting at base of thumb in advanced carpal tunnel.
- Two-Point Discrimination Testing: Evaluating sensory acuity on fingertips (<6mm normal).
- Thumb Abduction Strength Test: Testing abductor pollicis brevis power.
- Durkan’s Compression Test: Direct thumb pressure over carpal tunnel for 30 seconds.
- Active & Passive ROM Goniometry: Measuring wrist flexion, extension, and thumb mobility.
- Grind Test for CMC Arthritis: Axial compression and rotation of thumb basal joint.
- Froment’s Sign Check: Ruling out ulnar nerve compensation during pinch.
- Grip & Pinch Dynamometry: Quantifying hand strength deficits.
- Physical Baseline Record: Logging Phalen's onset time and Finkelstein pain threshold.
4. EMG/NCS, Ultrasound & Care Roadmap
