Orthopedic rehabilitation therapy has the following effects: 1. Muscle contraction can promote local blood and lymphatic circulation, and at the same time can stimulate the production of a large number of bone scabs at the fracture end to promote bone healing and prevent bone decalcification. 2.Maintaining certain muscle contraction movement can prevent disuse muscle atrophy. 3.Joint movement can stretch the joint capsule and ligaments to prevent their shortening, and can promote the secretion and circulation of intra-articular lubricating fluid, thus preventing intra-articular adhesions. 4.Promote the absorption of local hematoma and exudate, and reduce edema and adhesions. 5.Promote the recovery of neuromuscular reflexes and coordination functions, for example, after artificial hip and knee joint replacement, after proprioceptive training, it helps the recovery of lower limb joint balance and coordination ability. 6.Improve patient’s mood, enhance metabolism, improve respiratory, circulatory and digestive system functions, and prevent the occurrence of comorbidities.
