Wrist Drop & Radial Nerve Palsy Physiotherapy Treatment

Overview of Wrist Drop & Radial Nerve Palsy Physiotherapy Treatment

Unable to lift your hand at the wrist? Learn about radial nerve compression, causes of wrist drop, splints, and physical therapy exercises to regain hand function.

The radial nerve originates from the brachial plexus (C5-T1) and runs down the arm, supplying the triceps and wrist/finger extensor muscles.

Common Causes & Pathophysiology

Compression at the humerus (Saturday Night Palsy), fractures of the humerus shaft, prolonged crutch use pressing on the armpit, and deep cuts/wounds along the radial nerve pathway lead to wrist drop.

Common symptoms include localized tenderness, sharp pain during movements, swelling, bruising, and muscular tightness or spasms in the affected region.

Evidence-Based Physiotherapy Treatment

Rehabilitation involves: 1) Dynamic wrist extension splinting to maintain functional grip, 2) Electrical stimulation of extensor muscles, 3) Passive stretching to prevent flexion contractures, and 4) Guided active-assisted extension exercises.

Rehabilitation must be progressive, moving from pain reduction to strength restoration. Patients are advised to work under guided supervision to prevent reinjury.

Clinical Outlook & Next Steps

Early and accurate diagnosis is critical to avoid transforming acute tissue strains or nerve compressions into chronic dysfunction. If you suspect an injury, consult a physiotherapist for a personalized evaluation.
