The cpm therapy machine can be found in the post-operative rehabilitation phase of orthopedics, or in the conservative treatment of traumatic and sports injuries.

Functions of the cpm therapy machine.

The function of the cpm therapy machine is simply to restrain the joint in a reasonable manner and to help the joint to perform passive, reciprocal and continuous movements. The function of a joint is flexion, extension and rotation. After surgery or injury, the shoulder, elbow, knee, and hip are often unable to move adequately and safely due to limited active motion, pain, and limited ability, which can lead to soft tissue adhesions, heterotopic ossification, decreased mobility, venous embolism, difficulty with blood supply, persistent swelling, and pain. In such cases, the corresponding limb and joint can be fixed in the segmented CPM arm, and the cpm therapy machine's interactive interface can be used to set the appropriate degree of flexion and extension, frequency, force and time to promote healing and enhance the rehabilitation effect through reasonable parameter settings.

What can the cpm therapy machine do? What can't it do?

The cpm therapy machine can effectively free the hands of patients, family members and rehabilitation therapists, and instead, the electronic machine is programmed to carry out manual instructions, which is accurate, efficient and safe. However, it must be acknowledged that the cpm therapy machine is only an auxiliary device in the rehabilitation process, and although this device is effective, it is not a panacea.

Generally speaking, the cpm therapy machine can only be used to execute programmed manual instructions. Whether the relevant instructions are set scientifically or not, and whether the actual results are good, have nothing to do with the cpm therapy machine itself. In other words, the cpm therapy machine is only responsible for binding the limb and then continuously operating it. It is only a mechanical rehabilitation aid, not intelligent, and it cannot reduce the pain during passive movement, nor can it allow the joint to reach the end point of movement.

Advantages and disadvantages of the cpm therapy machine.

The advantages of the cpm therapy machine are continuity, precision, controllability, automation, and the ability to continue movement even while the patient is sleeping. However, the disadvantages of the cpm therapy machine are obvious and do not apply to all patients. cpm therapy machine has the following significant disadvantages.

1. Continuous passive motion may affect the rate of wound healing. Continuous movement can prevent internal soft tissue adhesions, but also make surgical incisions, skin wounds and other wounds that need to heal difficult to heal (in view of this, diabetic patients should reduce the frequency of use of cpm therapy machine).

2. Inability to fully straighten the joint. Joint straightening and maximum flexion are difficult to obtain through the CPM machine, and usually have to be achieved with manual assistance.

3, can not be effective strength training. cpm therapy machine training is only a small intensity of passive mobility exercises, the muscle strength improvement function is not significant.

4, abuse of cpm therapy machine may form fixed flexion deformity. cpm therapy machine activity angle, amplitude is relatively fixed, it is difficult to complete the lateral flexion, abduction, adduction, rotation and other complex movements, if long-term reliance on cpm therapy machine, may lead to fixed flexion deformity of the joint.

5、Only for specific joints. In view of the limitations of the range of activities and the way of fixation, cpm therapy machine is more suitable for passive activities of large joints such as shoulder, elbow, knee and hip, and less applied to joints such as spine, hand, foot and ankle.
