Brief Summary

The immobilization process after an operation or injury in the upper extremity causes a loss of muscle mass and strength of 0.2% and 1.3% per day, respectively. Currently, the use of cross-education, which is unilateral training in the uninjured limb, during the immobilization period, is expanding, demonstrating a magnitude of strength gain in the immobilized limb from 8% to 77% of the mean of strength of the trained limb. Despite the evidenced benefits of cross-education in unilateral injuries such as distal radius fracture, anterior cruciate ligament injury, and knee replacement, very little is known about this effect in shoulder immobilization after clavicle fracture.

Eligibility Criteria

Age18 Years - 40 Years
Sexmale(Gender-based eligibility)
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Men from 18 to 40 years old, diagnosed with radiographically verified clavicle fracture and awaiting surgical procedure. They have a body mass index of not less than 18.5 and not more than 29.9 kg/m2 and sign an informed consent.
