Introduction

About shoulder weakness

For normal function, each muscle must be healthy, conditioned, securely attached, and coordinated.

Weakness of the shoulder can come from deficits in coordination, nerve, muscle or tendon. Often, weak shoulders will respond to a gradually progressive strengthening program. If shoulder weakness does not respond to these exercises, it may be due to a rotator cuff problem, or a nerve injury. Here we will focus our attention the evaluation and management of the most common mechanical cause of shoulder weakness, rotator cuff failure.
