Carpal Tunnel Release Surgery: What to Expect from Physiotherapy Recovery

Carpal tunnel release surgery divides the transverse carpal ligament to relieve pressure on the median nerve at the wrist. The procedure -- performed as either open or endoscopic release -- typically takes under 30 minutes, but proper post-operative rehabilitation is key to regaining grip strength, finger dexterity, and pain-free hand use. Most patients recover full function within 6 to 12 weeks, though pillar pain around the incision can persist for several months.

What Happens After Surgery

The hand is usually bandaged with a soft dressing, and a wrist splint may be worn for the first 1-2 weeks to protect the surgical site. Finger movement is encouraged immediately -- patients should bend and straighten all fingers fully from day one to prevent tendon adhesions. Numbness and tingling often improve within days, though nerve recovery can take weeks to months if compression was severe or longstanding. Avoid lifting anything heavier than a cup of tea for the first 2 weeks, and keep the hand elevated when resting to limit swelling.

Physiotherapy Rehabilitation Phases

Early phase (weeks 1-3): Gentle active range-of-motion exercises begin immediately. Tendon gliding exercises -- making a hook fist, straight fist, and full fist in sequence -- keep the flexor tendons moving freely within the carpal tunnel. Wrist flexion and extension stretches are started gently. Scar desensitisation (rubbing the scar with different textures) and scar massage reduce hypersensitivity and prevent adhesions. Oedema management includes retrograde massage from fingertips toward the wrist.

Middle phase (weeks 3-6): Progressive grip strengthening begins with soft putty or a stress ball, starting with light resistance and increasing gradually. Wrist curls with a light resistance band target the wrist flexors and extensors. Nerve gliding exercises (median nerve flossing) help the nerve adapt to its new space within the tunnel. Fine motor tasks -- buttoning, writing, picking up coins -- are practised to restore dexterity. Your physiotherapist may use ultrasound therapy around the scar if adhesions are limiting movement.

Late phase (weeks 6-12): Strengthening intensifies with grip dynamometers, weight-bearing through the hands (e.g., modified push-ups against a wall), and functional task training specific to your work demands. If you use a keyboard or tools daily, workstation ergonomics are reviewed and adjusted. Pinch strength exercises using spring-loaded pinch gauges or small weights address the thenar muscles that may have weakened from prolonged nerve compression.

Return to Activity

Light desk work and typing can resume within 1-2 weeks for endoscopic release, or 2-3 weeks for open release. Manual work involving gripping, lifting, or vibrating tools typically requires 4-6 weeks off. Driving is usually possible at 1-2 weeks once you can grip the steering wheel comfortably. Full grip strength generally returns by 3 months. Red flags to report include worsening numbness or tingling (rather than improving), signs of wound infection such as increasing redness or pus, severe pain unresponsive to prescribed medication, or a sudden loss of finger movement.
