Neuralgic Amyotrophy:
A Practical Guide for OT and PT
Recognize the pattern. Match rehabilitation to the phase of recovery. Restore efficient movement and meaningful recovery
Neuralgic amyotrophy (NA), also known as Parsonage-Turner syndrome or brachial neuritis, is an episodic neuritis characterized by severe neuropathic pain followed by weakness, muscle atrophy, and functional limitations.
This page highlights practical strategies to help rehabilitation professionals understand the clinical course of NA, evaluate patients appropriately, and apply phase-specific rehabilitation strategies.

Recovery Has Phases
Rehabilitation priorities should change as the patient moves through the acute, neuropathic, and chronic phases of recovery.
Motor Control Before Strengthening
Prioritize efficient, coordinated movement before progressing strengthening.
Training Can Worsen Dyskinesia
Traditional strengthening may reinforce abnormal movement patterns and overwork weak or compensating muscles.PT + OT Collaboration Matters
Combining physical and occupational therapy strategies can improve carryover into daily activities, work, and meaningful participation.Quick Signs to Watch
- Severe pain followed by weakness
- Progressive weakness
- Unexplained muscle atrophy
- Scapular winging
1. UNderstanding neuralgic amyotrophy
Neuralgic amyotrophy is an episodic neuritis characterized by severe neuropathic pain followed by weakness and muscle atrophy. It most commonly affects the brachial plexus, although the lumbosacral plexus and phrenic nerve can also be involved.
The exact cause remains unclear. Current evidence suggests a multifactorial process involving immune, mechanical, and genetic contributors.
Incidence
1 in 1,000/yr
Men affected about
2x more often
than women
Most recover
70-90% function in 1-3 years
Why Rehabilitation Must Evolve
The acute, neuropathic, and chronic phases of neuralgic amyotrophy require different rehabilitation priorities. A one-size-fits-all approach may be ineffective or counterproductive.2. Clinical course: 3 phases
When diaphragmatic involvement is suspected, additional assessment such as spirometry or ultrasound may be indicated.
Acute Phase
- Sudden continuous intense pain.
- Often disrupts sleep
- Usually 3-4 weeks, but variable
- PT focus: symptom reduction, education, positioning, rest
Neuropathic Phase
- Pain becomes movement/posture dependent
- Weakness, fatigue, and sensory symptoms emerge
- PT focus: motor control and scapular coordination
- Avoid overloading weak muscles
Chronic Phase
- Secondary muscle and tendon pain may develop
- Compensatory movement patterns become prominent
- PT focus: gradual conditioning and functional strengthening
- Tailor progression to patient capacity and goals

Important Clinical Pearl
Training can worsen dyskinesia and symptoms
Traditional strengthening may reinforce abnormal movement patterns and overwork weak or compensating muscles. Prioritize efficient coordinated movements first.
3. PT Evaluation Essentials
History
Record information such as symptoms, functional limitations, participation restrictions, work demands, goals
Outcome Measures
- Pain rating
- Fatigue measures
- DASH or other upper-extremity function measures
Physical Exam
- Muscle atrophy
- Scapular winging/ dyskinesia
- Patchy weakness patterns
Strength Testing
- Start distally and progress proximally.
- Use MRC scale and/or handheld dynamometry
When diaphragmatic involvement is suspected, additional assessment such as spirometry or ultrasound may be indicated.
4. Rehabilitation Principles
Rehabilitation should be individualized and based on the phase of recovery, symptoms, and patient goals
Acute Management
- Symptom reduction
- Ergonomics and positioning
- Effective rest
- Refer for medical management when needed.
Motor Control and Scapular Coordination
Restore efficient, coordinated movement while minimizing overload
Fatigue Management
Pacing and energy management to balance activity and recovery. Progressive Activity
As motor control improves, add aerobic conditioning and gradual functional strengthening carefully and progressively
Progression should be careful, progressive, and tailored to the patient’s current capacity and goals.
5. Role of OT
- Energy conservation and activity modification
- Ergonomics and adaptive strategies
- Reintegration into work and daily activities
- Avoiding both overuse and complete inactivity
- Incorporate improved scapular coordination into dressing, household tasks, work tasks, and leisure activities.
6. PT+OT In Daily life
Collaboration bridges the gap between clinical gains and real-world function.
PT:
improve movement strategy
Better energy management
OT:
apply it to daily activities and work
More effective activity retraining
Patient:
better carryover into real life
Targeted ergonomic intervention
7. Workplace modifications
Many people with neuralgic amyotrophy can return to meaningful work. Persistent weakness and reduced endurance, however, may require temporary or longer-term accommodations.
Accommodations for Persistent Weakness
Modified duties, adaptive equipment, reduced lifting demands, task modification
Managing Reduced Endurance
Adjusted schedules, incorporate rest breaks, task rotation, and prioritizing essential activities. Gradual Return to Work
Increase hours and responsibilities based on tolerance, symptoms, and functional progress.If you think you might have a nerve problem, use our directory to identify a nerve expert to contact.
