Shoulder weakness during lifting can stem from several underlying issues. It's often a result of coordination problems, nerve issues, muscle weakness, or tendon problems.
Common Causes of Shoulder Weakness
- Muscle Weakness: Insufficient strength in the muscles surrounding the shoulder joint (like the rotator cuff muscles) directly impacts lifting capacity. This is often addressable with targeted strengthening exercises.
- Nerve Problems: Conditions affecting the nerves supplying the shoulder muscles can lead to weakness or even paralysis. This could stem from nerve impingement or other neurological issues.
- Tendon Issues: Problems with the tendons connecting muscles to bones, such as rotator cuff tears, significantly impair shoulder strength and function.
- Poor Coordination: Inefficient movement patterns and lack of proper muscle coordination can also make lifting difficult and lead to perceived weakness.
Addressing Shoulder Weakness
A gradual, progressive strengthening program often helps resolve shoulder weakness stemming from muscle deficits. However, if weakness persists despite these exercises, a more serious underlying problem like a rotator cuff injury or nerve damage may be present, warranting medical evaluation. As stated in a reference from February 10, 2005, "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."
