With the continuous development of rehabilitation medicine , isokinetic strength training system has been gradually applied in clinical medicine and scientific research . Isokinetic strength training has both evaluation and treatment functions . While conducting quantitative evaluation , it can also achieve the purpose of quantitative rehabilitation treatment plan . Today we will learn about this “black technology” isokinetic strength training .

What is isokinematic

Isokinetic exercise refers to an exercise in which the speed is constant and the resistance is variable. The speed is pre-set on the isokinetic instrument. Once the speed is set, no matter how much force the subject uses, the speed of the limb movement will not exceed the pre-set speed. The subject’s subjective effort can only increase muscle tension and torque output, but cannot produce acceleration.

• Advantages of constant speed

Isokinetic exercise technology has the advantages of accurate results, good repeatability, and can provide a large amount of specific data. It is efficient, safe, and controllable in treatment. It has the following advantages in muscle strength testing and rehabilitation treatment:

• Efficiency

Since isokinetic exercise provides compliant resistance, the muscle joints always produce maximum muscle force throughout the entire range of motion. Therefore, it can more effectively exercise muscle strength, endurance and flexibility, thereby improving the efficiency of rehabilitation training.

• Security

Isokinetic testing and training are relatively safe because the applied resistance changes according to the different motor strengths of the subjects. If the subjects are injured, weak, or powerless, the resistance will also decrease as the muscle strength decreases. In addition, since the speed is constant and no acceleration is generated, it is relatively safe.

• Comprehensiveness

Isokinetic strength testing covers a wide range of tests, including most functional movements of the large joints of the limbs, as well as strength tests of various functional movements of the waist and back muscles. The emergence of isokinetic exercise has played a great role in promoting rehabilitation medicine. The combination of isokinetic technology and clinical examination methods makes qualitative and quantitative examinations complement each other, and can obtain more real, objective and accurate results. The application of isokinetic technology in the field of rehabilitation enables doctors and therapists to accurately grasp the various mechanical parameters of the patient’s tested muscle groups, understand their functions and states, and develop reasonable rehabilitation plans to help patients recover better and return to society as soon as possible.

Isokinetic muscle strength testing applications

• Muscle function assessment

It can measure multiple muscle function indicators such as muscle strength, muscle endurance, explosive power, etc. These indicators can be used to judge the strength of muscle function.

• Joint stability assessment

The ratio of joint flexion/extension muscle strength reflects the strength of joint stability, thereby determining the risk of joint injury (especially the knee joint).

• Auxiliary diagnosis of sports system injuries

The measured torque curve is used to reflect the pathological conditions of muscles and joints.

• Evaluation of therapeutic effect

By providing objective data through testing, we can guide rehabilitation treatment plans and select appropriate treatment methods. It can also be used to determine the effectiveness of conservative treatment, surgical treatment, and rehabilitation training.

Isokinetic strength training methods

• Isokinetic Strength Training

It is the most commonly used method of muscle strength training. Since isokinetic instruments can provide different movement speeds, a series of different movement speeds can be selected for muscle strength training according to the needs of different diseases. This training method is also called movement speed spectrum training. The movement speed spectrum includes: slow speed (1°~60°/s), medium speed (60°~180°/s), fast speed (180°~300°/s) and functional movement speed (300°~1000°/s). Movement speed spectrum training includes two forms: muscle strength training, movement speed spectrum training and functional adaptability training.

• Isokinetic myocardial strength training

The equipment can provide two training methods: concentric contraction/eccentric contraction and eccentric contraction/eccentric contraction. In the former training method, one group of muscle groups is mainly trained, such as the clockwise direction is the concentric contraction of the muscle group, and the counterclockwise direction is the eccentric contraction of the same muscle group, thus forming a group of muscle groups with a continuous contraction mode of concentric contraction-eccentric contraction; the latter training method can simultaneously train the eccentric contraction strength of the two groups of muscle groups, the agonist and antagonist muscles, and improve the strength of the two groups of muscle groups; in clinical practice, it can be selected according to the specific conditions of the patients.

• Short arc isokinetic strength training

It refers to a method of isokinetic strength training within a limited range of motion, and is mainly suitable for patients with pain caused by limited joint movement after joint and surrounding soft tissue injuries. Injuries to the muscular system often lead to injuries to the joints and surrounding soft tissues. When the joints move to a certain angle, it can cause pain in the injured area, which is manifested as a “pain arc” on the torque curve. If you exercise within the pain arc, it may sometimes aggravate the injury or even cause new injuries, which is not conducive to the recovery of joint function.

The role of isokinetic strength training

1. Improve joint mobility, prevent and delay muscle atrophy;

2. Improve the muscle strength of the affected limb and reduce increased limb muscle tension caused by any reason;

3. It can train certain muscles in a targeted manner, increase the amount of blood returning to the heart, and prevent deep vein thrombosis in the lower limbs;

4. Enhance muscle strength, improve joint mobility, relieve muscle tension, and enhance joint stability;

5. Promote the recovery of proprioceptive sensation.

Isokinetic muscle strength training, with its constant speed and compliant resistance, has become an important means in the field of modern rehabilitation. Yikang Medical AI multi-joint isokinetic and testing system, with its comprehensive evaluation, accurate data, intelligent rehabilitation and high efficiency and convenience, has injected new vitality into rehabilitation medicine.
