骨质疏松可分为两大类型:全身性和局限性;老年或绝经期后骨质疏松、甲状腺或甲状旁腺机能亢进、皮质醇过多、肢端肥大等继发的骨质疏松均属于前者;骨折或骨关节疾病行石膏制动、中枢神经系统、脊髓或周围神经系统损伤导致肌肉瘫痪引起的骨质疏松则属于后者。运动增加骨承受的应力,骨对运动的反应是皮质厚度增加和骨髓腔缩小,骨体积因而增大;制动则在局部范围内使肌肉加于骨的机械性刺激丧失或减少,骨吸收多于骨形成,骨质更新(Turnover)和钙代谢都处于负平衡,表现为
Osteoporosis can be divided into two types: systemic and limitations; osteoporosis after aging or menopause, thyroid or hyperparathyroidism, excessive cortisol, acromegaly and other secondary osteoporosis are The former; fracture or bone and joint disease gingiva brake, central nervous system, spinal cord or peripheral nervous system damage caused by muscle paralysis caused by osteoporosis belong to the latter. Exercise increases the stress on the bone. The response of the bone to the exercise is an increase in cortical thickness and narrowing of the medullary cavity, thereby increasing the volume of the bone; braking reduces or decreases the mechanical stimulation of the muscle to the bone within a localized range In bone formation, bone turnover (turnover) and calcium metabolism are in negative balance, manifested as
