The implications for contralateral effects are tremendous. Any patient/client who has had an injury, and therefore immobilization / disuse for a period of time, should be able to preserve the strength of the musculature of the immobilized limb by performing resistance training of the healthy, non-immobilized limb.
The question should be asked: Why might walking be helpful for patients with low back pain? Although many mechanisms might be proposed, some likely scenarios are that walking strengthens, stretches, and mobilizes the myofascial tissues/joints of the lumbosacral-hip joint region.
These findings lend further evidence to suggest that treatment belief and the placebo effect may be largely responsible for the beneficial effects of cryotherapy on recovery following a marathon.
Early loading after a muscle strain injury is important because immobilization can swiftly and adversely affect muscle and tendon structure and function.
