Isokinetic exercise | rehabilitation evaluation and treatment
The concept of rehabilitation has been deeply rooted in people's hearts, however, for the understanding of rehabilitation treatment techniques, many people still only stay in acupuncture, massage, physical therapy, traction, etc.?Perhaps many people do not understand, or even have not heard of?isokinetic techniques.
In fact, isokinetic exercise technique is a commonly used clinical rehabilitation therapy technique, which was proposed as early as in 1960s, and after research and development over the years, it is now widely used in the field of rehabilitation medicine and sports medicine. In the late 1980s, China began to introduce isokinetic devices, which were initially mainly used for muscle function evaluation of athletes and muscle strength training after sports injuries, and then gradually applied to various fields such as neurological and skeletal muscle rehabilitation. In the following, we will introduce this technology to you.
Constant speed of movement with the help of equipment
Isokinetic motion, also known as adjustable resistance motion or constant angular velocity motion, refers to the use of specialized equipment to adjust the applied resistance accordingly to the change in muscle force during motion, so that the entire joint motion moves at a predetermined speed. Because of the need to sense the change of muscle force during the movement, the support of the induction system is needed to change the resistance level to match the change of muscle force level at any time, and also to obtain various mechanical parameters about the change of muscle force during the movement through the induction system, so that the muscle force test can be done objectively and quantitatively.
The distinctive feature of isokinetic exercise is that the speed of movement is relatively stable and does not produce explosive isokinetic phenomena. The resistance generated throughout the movement process is proportional to the muscle force acting. That is, the muscle can produce the maximum force at any point in the whole process of movement, thus continuously enhancing muscle strength.

Improving the efficiency and safety of rehabilitation training
The isokinetic technique is characterized by accurate and reproducible results, and it provides a large amount of specific data.?It has the advantage of being efficient, safe and controllable in treatment.
First, because the isokinetic exercises?provides?the compliance resistance, the muscle joints in the full range of motion always produce the maximum muscle force, therefore, it can be more effective forging muscle strength, endurance and flexibility?so that improves?the efficiency of rehabilitation training.
Second, in isokinetic testing and training, the applied resistance is changed according to the patient's different exercise strength. The resistance will also decrease as the muscle strength decreases.?And because the velocity is constant and no acceleration is generated, the safety is higher.
Third, isometric muscle strength testing has a wide range of applications, including most of the functional movements of the large joints of the extremities, as well as muscle strength testing of the functional movements of the lumbar and back muscles.
