Management of Radial Nerve Palsy

Primary Treatment Recommendation

The American Academy of Physical Medicine and Rehabilitation recommends initiating a structured occupational therapy program focused on functional task training with normal movement patterns, combined with dynamic splinting that provides wrist and finger extension support through a tenodesis mechanism, while avoiding static immobilization that could worsen weakness 1

The Journal of Neurology, Neurosurgery and Psychiatry advises against using serial casting or prolonged static immobilization, as this worsens symptoms, causes muscle deconditioning, promotes learned non-use, and can trigger complex regional pain syndrome 2, 3

The American Occupational Therapy Association recommends performing functional tasks that promote normal movement, proper alignment, and even weight-bearing of the affected hand, including using the hand to stabilize objects during activities, placing the hand on surfaces while standing, and bilateral upper extremity tasks 2, 1
The American Physical Therapy Association suggests grading activities progressively to increase the time the affected hand is used within functional tasks, employing normal movement techniques and avoiding compensatory strategies that reinforce abnormal patterns 1

The American College of Sports Medicine prescribes a directed home exercise program as the primary therapy modality, as evidence shows home programs are equivalent to supervised therapy for uncomplicated radial nerve palsy cases 1
The National Institute of Neurological Disorders and Stroke recommends performing active finger motion exercises regularly from the initial encounter, including stretching exercises for wrist flexors and extensors 1, 4

The American Heart Association considers Functional Electrical Stimulation (FES) for patients with demonstrated impaired muscle contraction, specifically for wrist motor impairment, as it provides short-term increases in motor strength and motor control 5

The American Academy of Physical Medicine and Rehabilitation reassesses function every 2-3 weeks to evaluate splint effectiveness, adjust therapy progression, and monitor for any adverse effects from splinting 3
The Journal of Neurology, Neurosurgery and Psychiatry uses video recording interventions (with consent) to demonstrate changeability in symptoms, highlight successes, and serve as reference points for replicating successful strategies 2
