In the late 1960s, Hislop pioneered the theory of isokinetic exercise, and early isokinetic devices were introduced in the early 1970s. Since then, isokinetic exercise has been widely used in many aspects of rehabilitation medicine, sports medicine and orthopedics with its unique features. In order to better develop the level of rehabilitation assessment and rehabilitation treatment in our hospital, and to provide patients with more advanced and more objective and effective assessment and training programs, our department purchased the IsoMed2000 isokinetic muscle assessment and training system: I. Overview of the IsoMed2000 isokinetic muscle assessment and training system: 1. Isokinetic exercise, also known as adjustable resistance exercise or constant angular velocity exercise, has the following two characteristics: (1) the isokinetic movement, which has the following characteristics: (2) the isokinetic movement, which has the following characteristics: (3) the isokinetic movement, which has the following features Has the following two characteristics: (1) constant speed (2) adjustable resistance, these two features ensure its accurate muscle testing and optimal muscle training in two aspects. Therefore, isokinetic testing and training has more advantages. 2, IsoMed2000 isokinetic muscle evaluation and training system not only has the advantages of the previous generations of isokinetic trainers, but also has its own characteristics. (1) The test and training programs are greatly broadened compared with the previous ones. Not only provides a centripetal contraction mode, also provides a centrifugal contraction mode; specifically for the determination and training of the lumbar back muscles of the components to further extend the isokinetic movement from the limbs of the large joints to the spine; isokinetic sustained passive movement so that the use of isokinetic devices to complete the test of the weak muscle patients and contact becomes possible. (2) The reliability of test results and the safety of training can be further guaranteed. For example, laser positioning is applied to better ensure the consistency of the axis of joint motion and the axis of the linkage arm, and gravity compensation is used to reduce the effect of gravity on motion. (3) Create convenient conditions for better scientific research or more scientific completion of force measurement and training tasks. It has a feedback video system, and the additional synchronized EMG system provides the information of EMG activity at the same time. 3, the current isokinetic exercise test is mainly applied in two aspects: (1) the application of the sports system is mainly concentrated in the knee, shoulder joints and other sports injuries more joints, and mainly involved in joint ligament injuries and other diseases; tends to chronic bone and joint diseases of the functional evaluation; can also be used as one of the evaluation methods of occupational injuries. (2) Neurological aspects of the assessment of spasticity, hemiplegic motor function assessment. 4, isometric training research mainly focuses on (1) isometric centripetal contraction training and isometric centrifugal contraction training effect comparison, including analysis of normal people and hemiplegic patients muscle group muscle strength after exercise to improve the role. (2) Mechanisms of muscle strength enhancement by isokinetic exercise and its effects in terms of bone and joint injuries (3) Side effects of isokinetic exercise training. (4) Effects of isometric exercise on spasticity. (5) The effect of isokinetic exercise on the daily life interaction ability of hemiplegic patients. ISOMed2000 is equipped with a variety of training modes: isokinetic contraction (centripetal/centrifugal flexion/extension), isometric contraction and active exercise. From these, it is possible to combine a variety of exercise prescriptions to meet the patient’s specific situation, and to give the best treatment program according to the patient’s actual condition. Combined with the actual situation of our hospital, we consider that ISOMed2000 can be utilized to carry out the following tasks: 1. Firstly, in the aspect of evaluation: (1) Carry out isometric exercise test in each direction of joint activity of the knee and shoulder joints of normal people, and set up a preliminary database of isometric flexion and extension muscle strength of the knee and shoulder joints of normal people in each direction. (2) In neurological diseases can be carried out is in the spasticity of the objective quantitative assessment and hemiplegia motor function assessment, can also be used for pediatric cerebral palsy, paraplegia and so on. (3) Provide objective quantitative reference of muscle strength and functional impairment for the evaluation of physical disability. (2) Secondly, in terms of rehabilitation evaluation and treatment: applying ISOMed2000 to provide objective and quantitative reference for the evaluation of physical disability and functional impairment, so as to provide a better basis for the rehabilitation treatment and enable the therapist to adjust the rehabilitation treatment program more accurately and timely: (1) Combine the isokinetic test and training system with the existing rehabilitation treatment technology, and apply isokinetic exercise training in the daily rehabilitation treatment. (1) Combine the isokinetic testing and training system with the existing rehabilitation techniques, and apply isokinetic training to daily rehabilitation treatment. The rehabilitation assessment and training will be more objective and quantitative, more intuitive, and systematic to compare the patient’s training situation and adjust the training program, such as cerebrovascular accident sequelae patients before and after the rehabilitation treatment for functional assessment, in order to objectively evaluate the degree of functional impairment, treatment effect, and the next stage of the development and feasibility of the treatment plan. (2) To evaluate the spasticity of patients with cerebral palsy and hemiplegia, and to observe whether isokinetic training affects the spasticity of hemiplegic patients; (3) To evaluate the motor function of hemiplegic patients as a method to evaluate the efficacy of the rehabilitation training and to provide a reference suggestion for the development of the rehabilitation treatment program. (4) To assess the efficacy of treatment of knee, shoulder, ankle and other joint diseases, such as degenerative knee joints, joint ligament injuries, frozen shoulder, etc., and to objectively evaluate the treatment effect. (5) To study the comparison of knee flexion and extension strength of hemiplegic patients on the affected side, to provide a program for hemiplegic patients’ lower limb muscle strength training and inhibition of knee anteversion; (6) To carry out isokinetic exercise training for paraplegic patients’ lower limbs, and compare the effect of the training with that of the conventional rehabilitation training.
