Q

What are general rehab principles for shoulder area nerve injury?

A

Evidence of improvement with nonsurgical rehab
If denervated, support those muscles with splinting, AAROM exercises
Electrical stimulation not shown to be beneficial
Recovery can be lengthy and uncertain outome; so be patient and do no harm
Control inflammation
Do not overstretch denervated muscles
Do not stretch injured nerves or pressure over the nerve
Prevent digit contractures by maintaining range of motion
Perform low-load strengthening exercises without muscle fatigue or failure
Increase strengthening dosage as voluntary muscle power returns
