With a closed, edematous radial nerve palsy causing wrist drop and currently undergoing full therapy (night‑time wrist‑extension splint, anti‑inflammatory medication, nerve‑gliding and strengthening exercises), will my wrist drop improve and what is the expected recovery time?

Will My Wrist Drop Improve with Full Therapy?

Yes, your wrist drop will almost certainly improve, but complete functional recovery requires sustained treatment for 3–6 months, not just the initial weeks of therapy. 1

Expected Recovery Timeline

Your prognosis is excellent based on the closed nature of your injury:

  • Most traumatic radial nerve palsies recover spontaneously, with initial signs of nerve recovery appearing between 2 weeks and 6 months after injury. 2
  • Full wrist-extension strength is highly likely, but you must continue splinting and therapy for the entire 3–6 month period to achieve complete functional recovery. 1
  • The majority of motor recovery gains occur within the first 6 months, making this a critical window for intensive rehabilitation. 3
  • In documented cases of radial nerve palsy from compression (similar mechanism to your edematous injury), patients achieved complete recovery of wrist extensors and fair recovery of finger extensors after 3 months of physical therapy. 4

Critical Management Requirements

Splinting Protocol (Non-Negotiable)

Continue your night-time wrist-extension splint 24 hours per day (removing only for therapy sessions) to prevent wrist-drop contracture while the nerve regenerates. 1 This is endorsed by the American College of Radiology as definitive treatment. 1

Common pitfall: Do not discontinue splinting prematurely—sustained splint use for several months is essential to prevent contracture, even after wrist drop begins to improve. 1

Required Therapy Components

Your current therapy should include all of the following:

  • Daily passive stretching of wrist and finger extensors to maintain soft-tissue length and prevent shortening. 1
  • 30 minutes of wrist positioning in maximal extension each day while seated or supine to promote optimal alignment. 1
  • Task-specific wrist extension training with functional activities that progressively challenge wrist control with graded difficulty. 3
  • Resistance training starting at 40% of 1-repetition maximum with 10–15 repetitions, performed 2–3 times per week. 3
  • Neuromuscular re-education focused on movement quality (not just strength) as motor function returns. 1

Adjunctive Treatment Option

Functional Electrical Stimulation (FES) applied to wrist and forearm extensor muscles is recommended by the World Stroke Organization and American Heart Association as an adjunct to task-specific training for patients with impaired muscle contraction. 3 This should be combined with motor practice, not used as standalone treatment. 3

Imaging You Need Now

Obtain plain radiographs of your entire forearm and elbow immediately to exclude occult fractures or bony lesions compressing the radial nerve. 1 Occult fractures may be present even without reported trauma. 1

If radiographs are normal, proceed with non-contrast MRI to assess for nerve compression, soft-tissue masses, or intrinsic nerve injury. 1

Warning Signs Requiring Urgent Referral

Seek immediate hand surgery or neurology consultation if you develop:

  • Progressive numbness or weakness despite ongoing therapy. 1
  • MRI evidence of a compressive mass or nerve discontinuity. 1

What NOT to Do

  • Do not rely on passive range of motion alone—active motor practice is essential. 3
  • Do not progress resistance training too quickly—start with very low intensity to avoid muscle damage. 3
  • Do not position your wrist at end ranges for prolonged periods, which exacerbates symptoms and may impede recovery. 3

Bottom Line on Recovery Time

With your closed, edematous injury and current comprehensive therapy, expect:

  • Rapid symptom relief within 3–4 months with appropriate rehabilitation. 3
  • Optimal functional recovery requiring 9–12 months of continued rehabilitation depending on your return-to-work goals. 3
  • Most recovery occurring in the first 6 months, but full strength restoration taking up to 6 months of sustained treatment. 1, 3

The closed nature of your injury (no wound) and presence of edema rather than fracture suggests a compression neuropathy with excellent prognosis, similar to documented cases showing complete recovery. 4, 5
