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.
