Orthopaedic diseases and injuries form long-term limb braking, will produce joint adhesion, joint stiffness, pain, muscle atrophy, wasting osteoporosis and advanced degenerative arthritis and other complications for intra-articular fracture of the limb after immobilization occurs atraumatic arthritis, tendon loosening and reconstruction of the fixed after surgery to re-adhesion, etc., Continuous Passive Mobility (CPM) device application can greatly reduce these complications The application of continuous passive motion (CPM) device can greatly reduce the occurrence of these complications. CPM, also called continuous passive motion, is a new biological concept that accelerates the healing and regeneration of articular cartilage and the surrounding ligaments and tendons under the effect of continuous passive motion. It has been proved by experiments that early intermittent activity is better than braking, and continuous passive activity is better than intermittent activity. Since skeletal muscles are easily fatigued and cannot adhere to active activities for a long period of time, continuous passive activities are proposed. For example: knee stiffness is a common complication of lower limb fracture, clinical upper and lower limb fracture after surgery due to long-term restriction of activities can cause adhesion, contracture, stiffness and other complications of the knee joint, CPM provides a good passive functional exercise device for the clinic, our department from 2013, through the lower limb fracture patients after surgery to implement the painless continuous passive activity, the effect of its functional recovery is satisfactory, reducing the disability rate, and greatly promote the early functional rehabilitation of the knee. Greatly promote the early recovery of knee function, reduce hospitalization days, now for the CPM machine in orthopedic rehabilitation application for a description: according to the patient's affected limb thigh and calf length, adjust the length of the CPM machine rod, tighten the knob.
I. How to use CPM machine: 1. Adjust the CPM machine according to the required range of motion of the joints after surgery, the lower limb should be in the abduction 10-20 when it is placed on the CPM machine, and it should be in the neutral position with the toe upward, wearing the fixed shoe cover, fixing the calf and the thigh on the CPM machine, and keeping the affected side of the buttock as close as possible to the movable pivot, the speed of the operation should be from slow to fast, and the amplitude should be from small to large, and the general postoperative period should be from 5 to 8 years. The operation speed is from slow to fast and the amplitude is from small to large. Generally, the machine will be used within 24-48 hours after the operation, and the practice will be started 1 week after the operation of the artificial joint, or it can be delayed for 24-48 hours according to the patient's physical condition. 2. On the first day, from 0 to 40 in the morning, increase 5 every 15mm to reach 60; in the afternoon, from 5 to 50 in the morning, increase 5 every 15mm to reach 60; on the third day, from 5 to 50 in the morning, increase 5 every 15mm to reach 60. On the third day 5?-80? in the morning, every 15mm increased by 5?, directly approaching 90?, 5?-70? in the afternoon, the 15thmm increased by 5?, until 90?. Second, note: the foot of the affected limb and the shoe cover to set solid and the horizontal line is 90?, pay attention to the distance between the affected limb and the knee joint and the foot cover and the distance between the angle should be equal, the affected limb knee joint and the machine angle should be at the same level, increase the angle should be gradual, the patient should be able to accept, just increase the angle of the joints of the affected limb, the affected limb joints with a feeling of tightness and do not know the sense of pain, but the exercise for 5 minutes after the symptom will be relieved very quickly. Before the restorer starts to work, the speed should be adjusted to the minimum position, (see page 3 at the speed of movement) and then press the "start" button, start and then gradually adjust the speed faster, the termination angle must be greater than the starting angle, otherwise the machine refuses to work. Third, according to the knee joint function evaluation standards to assess the efficacy of treatment, can be divided into excellent, good, general, poor four classes
