It is now believed that patients with peripheral neuropathy-induced limb movement disorders (muscle atrophy, muscle bundle tremor, spasticity, etc.) can significantly reduce or alleviate the sequelae after regular rehabilitation training, and some people regard rehabilitation as particularly simple, or even equate it with “exercise”, and are eager to achieve results, often with half the effort, and leading to joint and muscle injuries, fractures This can lead to joint and muscle injuries, fractures, shoulder and hip pain, increased spasticity, abnormal spasticity patterns and abnormal gait, as well as foot drop and pronation, i.e. “misuse syndrome”. Improper plyometric training can aggravate spasticity, and proper rehabilitation can relieve this spasticity and lead to coordination of limb movements. Once the wrong training method is used, such as repeatedly practicing forceful grasping with the affected hand, it will strengthen the flexor muscle synergy of the affected upper limb, which will aggravate the spasm of the muscles responsible for joint flexion and cause deformities in elbow flexion, wrist flexion and finger flexion, making it more difficult to restore hand function. In fact, peripheral neuropathy is not only a problem of muscle weakness, but the uncoordinated muscle contraction is also an important cause of motor dysfunction. Therefore, it should not be mistaken that rehabilitation training is strength training. In the rehabilitation treatment of motor dysfunction in patients with muscular atrophy, the traditional concept and method only focus on restoring the patient’s muscle strength, neglecting the rehabilitation of the patient’s joint mobility, muscle tone and coordination between antagonism. Even if the patient’s muscle strength is restored to normal, the abnormal movement pattern may remain, thus hindering the improvement of his daily life and activity. Experimental and clinical studies have shown that, due to the plasticity of the central nervous system, there is a possibility of functional recovery during the recovery process after brain injury. Currently, it is generally recommended nationally and internationally to use a home-based multi-functional limb movement rehabilitation device to restore the movement of damaged muscular atrophy limbs in daily home care rehabilitation treatment. In addition to the direct exercise of muscle strength, the passive antagonism of the simulated movement coordinates and governs the functional state of the limb and restores its dynamic balance; at the same time, multiple repetitions of movement can provide feedback to the brain to promote information, so that it can maximize the functional reconstruction as soon as possible, break the spasticity pattern The therapy is easy to operate, especially for home use, and restores voluntary motor control. This therapy can make the muscular atrophy limb simulate normal movement, which helps to enhance the patient’s self-confidence in rehabilitation and restore muscle tone and limb movement in patients with muscular atrophy.
