Abduktionsparese

Abduktionsparese refers to a weakness or partial paralysis of the muscles responsible for abducting a joint. Abduction is the movement of a limb or body part away from the midline of the body. Therefore, an abduktionsparese specifically affects the ability to move a part of the body outwards.

The most common site for abduktionsparese is the shoulder joint, leading to difficulty lifting the arm away from the side. This is often caused by damage or dysfunction of the supraspinatus muscle or the suprascapular nerve, which innervates it. Other joints can also be affected, though less frequently, such as the hip or fingers, depending on the specific muscles and nerves involved.

Symptoms of abduktionsparese can include pain, a feeling of weakness, reduced range of motion, and difficulty performing actions that require outward movement. The underlying cause can vary and may include nerve injuries, muscle tears, inflammatory conditions, or neurological disorders. Diagnosis typically involves a physical examination, nerve conduction studies, electromyography (EMG), and imaging techniques like MRI or ultrasound.

Treatment strategies depend on the cause and severity of the abduktionsparese. They may include physical therapy to strengthen affected muscles and improve function, pain management, medication, or in some cases, surgical intervention to repair nerve damage or torn muscles. Rehabilitation is often a crucial component in regaining lost function and improving the patient's quality of life.
