Carpal Tunnel Syndrome Treatment in Tel Aviv

What is Carpal Tunnel Syndrome?

Carpal tunnel syndrome (CTS) is the most common peripheral nerve compression disorder, affecting 3.8% of the general population. The median nerve passes through the carpal tunnel in the wrist alongside nine flexor tendons. When tunnel pressure exceeds normal levels (2-10 mmHg), the median nerve becomes compressed, causing numbness, tingling, and pain in the thumb, index, and middle fingers.

CTS prevalence is 3.8% with NCS confirmation. Women are 2-3 times more likely to develop CTS than men. Occupational risk factors include repetitive gripping, prolonged wrist flexion, and vibration exposure. Pregnancy-associated CTS occurs in 25-50% of pregnant women and resolves postpartum in 70% of cases without intervention.

Symptoms and Progression

• Early Stage: Nocturnal numbness in thumb and fingers; Flick Sign positive (shaking hand relieves symptoms); morning stiffness
• Progressive: Daytime symptoms increasing; weakness in pinch and grip; clumsiness with fine motor tasks
• Advanced: Constant numbness; thenar eminence atrophy; permanent sensory loss; severe functional impairment

Clinical Diagnosis and Assessment

Diagnosis combines clinical presentation with objective testing. The Flick Sign (shaking hand to relieve symptoms) has the highest sensitivity (93%) among bedside tests. The Phalen test (sustained wrist flexion) reproduces symptoms in 50-68% of CTS patients. Tinel sign (percussion over median nerve) has moderate sensitivity (50%) and specificity (77%).

Clinical Tests for CTS:

• Flick Sign: Sensitivity 93%, most reliable bedside test
• Phalen Test: Sustained wrist flexion; sensitivity 50-68%
• Tinel Sign: Percussion over nerve; sensitivity 50%, specificity 77%
• Durkan Compression Test: Direct compression of carpal tunnel
• Electrodiagnostic Testing (Gold Standard): Nerve Conduction Studies (NCS) and EMG confirm diagnosis

CTS Severity Staging and Treatment Approach

Evidence-Based Conservative Treatment

Night Splinting (Cock-up Wrist Splint)

Night splinting maintains the wrist in neutral position (0 degrees extension/flexion) during sleep, reducing nocturnal median nerve compression. This simple, low-cost intervention is effective for mild-moderate CTS. Compliance is key — splint use must be consistent.

Neural Mobilization and Nerve Gliding Exercises

A 2010 systematic review found neural mobilization reduces CTS symptoms by 47% compared to 23% in controls at 6 weeks. Gentle, progressive exercises promote median, radial, and ulnar nerve gliding without tendon adhesion formation. Specific sequence: place hand behind head, extend arm, supinate forearm, extend wrist and fingers — repeat 2x daily.

Corticosteroid Injection

A landmark 2002 RCT (n=163) showed corticosteroid injection had 58% success rate at 3 months versus 31% for splinting alone. However, at 12 months, success rates converge, suggesting injection provides rapid short-term relief. Combined injection + physiotherapy is superior to either alone.

Ergonomic Modification and Workplace Assessment

• Keyboard: Elbows at 90 degrees; wrist in neutral position during typing
• Mouse: Avoid gripping; use vertical or ergonomic mouse designs
• Desk Height: Forearms parallel to floor when seated
• Break Frequency: 5-minute break every 30 minutes of repetitive work
• Wrist Positioning: Avoid prolonged flexion or extension

Stretching and Strengthening Protocol

Gentle wrist extensors and flexors stretching, performed 2-3 times daily, relieves tension. Intrinsic hand strengthening (finger abduction/adduction) reestablishes neuromuscular control without exacerbating compression. Progressive resistance, beginning with isometric holds, builds functional capacity.

When Surgery is Indicated (Carpal Tunnel Release)

Surgical carpal tunnel release (CTR) is indicated when conservative care fails after 3-6 months, or when severe symptoms and EMG evidence of motor loss indicate imminent permanent damage. Open release and endoscopic release are equally effective long-term, with endoscopic offering faster return to activity. Research shows surgical relief is superior to splinting at 3-6 months in moderate-severe CTS.

Treatment Timeline and Expectations

• Weeks 1-2: Splint initiation, ergonomic assessment, baseline symptom tracking
• Weeks 3-6: Neural mobilization and grip strengthening begin; symptom improvement expected
• Weeks 6-12: Progressive strengthening, return to light activity with ergonomic modifications
• Beyond 12 weeks: Full work capacity restoration; maintenance stretching protocol

Frequently Asked Questions

Median Nerve Anatomy and Compression Mechanism

The carpal tunnel is an osseoligamentous channel at the base of the palm, bounded posteriorly by the carpal bones (forming a concave arch) and anteriorly by the transverse carpal ligament (flexor retinaculum). Within this rigid compartment pass nine flexor tendons (FDS ×4, FDP ×4, FPL ×1) plus the median nerve. The tunnel's cross-sectional area is approximately 1.5-2.0 cm² at rest; wrist flexion beyond 40° or extension beyond 50° reduces this by 20-30%, compressing the nerve and elevating tunnel pressure from a baseline of 2-10 mmHg to 30+ mmHg (Gelberman et al., J Hand Surg 1981). Pressures above 30 mmHg impair epineural blood flow; above 60 mmHg, intraneural oedema forms, progressing to demyelination and ultimately axonal loss if sustained.

Diagnostic Tests in Detail

Clinical diagnosis of CTS relies on a combination of history and provocative tests. The Flick Sign — asking whether symptoms are relieved by shaking or flicking the hand (as if trying to shake down a thermometer) — carries 93% sensitivity and 96% specificity, making it the single most discriminating bedside test (Pryse-Phillips, Can J Neurol Sci 1984). The Phalen test (sustained wrist flexion for 60 seconds) achieves 68% sensitivity and 73% specificity; the Tinel's sign (percussion over the carpal tunnel) has only 50% sensitivity but 77% specificity. The Durkan compression test (direct digital compression over the tunnel for 30 seconds) improves on Tinel's: sensitivity 87%, specificity 90% (Durkan, J Bone Joint Surg Am 1991). Electrodiagnostic testing remains the gold standard: sensory nerve conduction velocity below 50 m/s and distal motor latency above 4.2 ms confirm CTS and grade its severity.

Neural Mobilisation for CTS

Neural gliding exercises for CTS aim to restore the normal excursion of the median nerve through the carpal tunnel. The nerve normally glides 9.6mm during full wrist flexion-extension (Wehbé & Hunter, J Hand Surg 1985). Two categories of exercises are prescribed:

1. Tendon gliding exercises: sequential hand positions (straight, hook, full fist, tabletop, straight fist, OK sign) promote differential gliding of the flexor tendons relative to each other and the median nerve, reducing adhesions
2. Nerve gliding (slider) exercises: wrist extension + finger extension while depressing the shoulder — creates a gentle longitudinal stretch of the median nerve without excessive tension. 10 repetitions, 3 times daily

Huisstede et al. (Arch Phys Med Rehabil 2010) demonstrated that nerve gliding reduces CTS symptoms by 47% versus 23% in the control group at 6 weeks, with the greatest effect in mild-to-moderate cases. Contraindication: severe CTS with constant numbness (Stage 3) — forceful neural mobilisation may worsen symptoms; these patients require prompt surgical referral.

Night Splinting Protocol

The rationale for nocturnal splinting is straightforward: during sleep, 80% of people maintain prolonged wrist flexion (mean 47°), which elevates carpal tunnel pressure and generates the nocturnal tingling pathognomonic of early CTS. A cock-up splint holding the wrist in 0-15° extension (neutral position) normalises tunnel pressure and restores epineural blood flow within 3-6 minutes. Meta-analysis (Huisstede et al., Arch Phys Med Rehabil 2010) confirms: 6-8 weeks of nightly splinting improves symptoms in 70% of mild-moderate CTS cases, with 30-40% still in remission at 12 months. Full wrist extension splints (30-35°) are not superior and are poorly tolerated. Daytime splinting is reserved for occupational exposure (keyboard/tool use) and worn only during provocative activities to avoid disuse muscle atrophy.
