Physiotherapy for Wrist Drop
What is Wrist Drop?
Wrist drop, also known as radial nerve palsy, is a condition where a person is unable to lift the back of their hand or extend their wrist and fingers. This occurs due to damage or compression of the radial nerve, which controls wrist and finger extension.
Causes of Wrist Drop
Wrist drop is usually caused by:
✅ Radial Nerve Compression – Due to prolonged pressure on the arm (e.g., sleeping with the arm hanging over a chair).
✅ Fractures – Humerus or radius bone fractures can injure the radial nerve.
✅ Nerve Injuries – Direct trauma, cuts, or crush injuries.
✅ Medical Conditions – Diabetes, stroke, or lead poisoning affecting nerve function.
✅ Prolonged Use of Crutches – Can compress the radial nerve in the armpit.
Symptoms of Wrist Drop
✔ Inability to extend the wrist and fingers
✔ Weakness in the forearm and hand
✔ Numbness or tingling along the radial nerve
✔ Difficulty gripping objects
✔ A drooping hand position
Role of Physiotherapy in Wrist Drop
Physiotherapy plays a vital role in recovering wrist function and preventing muscle weakness. A structured rehabilitation program focuses on:
1. Nerve Stimulation and Activation
✅ Electrical Stimulation (TENS) – Helps activate weakened muscles.
✅ Passive and Active Exercises – To restore movement.
2. Strengthening Exercises
✅ Wrist Extension Exercises – Using resistance bands to strengthen wrist extensors.
✅ Grip Strengthening – Using therapy balls to improve hand function.
3. Range of Motion (ROM) Exercises
✅ Prevents joint stiffness and improves flexibility.
4. Splinting and Bracing
✅ Wrist Splints – Support the hand and prevent contractures.
✅ Dynamic Splints – Assist wrist extension during rehabilitation.
5. Functional Training
✅ Practicing daily activities to improve independence and hand function.
Recovery Time for Wrist Drop
The recovery time depends on the severity of the nerve injury:
- Mild compression injuries: 4 to 6 weeks
- Moderate nerve damage: 3 to 6 months
- Severe cases (nerve rupture or surgery needed): 6 months to a year
Early physiotherapy intervention improves outcomes significantly!
Conclusion
Wrist drop can severely affect hand function, but timely physiotherapy can restore mobility, strength, and independence. If you or someone you know has wrist drop, consult a physiotherapist for a personalized rehabilitation plan!
