Analysis of Shoulder Muscle Activity During Isokinetic Evaluation of Rotators

Analysis of Shoulder Muscle Activity During Isokinetic Evaluation of Rotators

The objective of this study is to assess the impact of different positions of the glenohumeral joint on the maximum muscle contraction of different shoulder muscles. The muscles do not contract with the same intensity depending on the position of the arm in relation to the trunk. With the determination of this optimal position to activate the shoulder muscles as much as possible, we will be able to strengthen the patients during their revalidation.

Inclusion Criteria:

• Male subjects aged 18-35.
• Playing a sport using the upper limb (handball, volleyball, swimming, tennis) at least 6h/week

Exclusion Criteria:

• Pain in the shoulder
• Shoulder pathologies such as gleno-humeral dislocation, tendinopathy, sub-acromial conflict, etc.
• History of shoulder surgery (prosthesis, stabilizing surgery, etc.)
