INTERVENTIONAL
Conditions
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
Inclusion Criteria1
- 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.
Exclusion Criteria5
- Patients with previous injuries, pathological fracture or polytrauma
- Patients who report pain, a history of rotator cuff tear or surgery in the non-injured upper extremity.
- Patients with uncontrolled cardiovascular diseases.
- Any history of neurological problems in the upper extremities.
- Use of nutritional supplementation (leucine, glutamine, casein, whey-protein, fatty acids and creatine) and/or Hormonal Replacement Therapy.
