Muscle fiber tremor can start at the distal end of one upper extremity, then spread to the ipsilateral lower extremity and the opposite upper extremity, and the lips, tongue, jaw and head are the last to be involved, and the tremor can be aggravated by emotional excitement and stop completely during sleep anesthesia. Muscle contracture: A clinical syndrome in which the muscles and the fascial fibers in the area where the muscles are located are degenerated and contracted, leading to a characteristic gait and signs of restricted joint function. Muscle contracture, postural deformity at the site of contracture, severe pain around the joint, indentation on the skin, and limited abduction and internal flexion of the joints of the extremities. Muscle tension pain is a clinical manifestation of neurological disorders. Neurosis is a neurological disorder in which the brain and somatic functions are mainly weakened. It is characterized by easy mental excitement but easy fatigue, often accompanied by emotional symptoms such as tension, worry, irritability and other symptoms of physiological disorders such as muscle tension pain and sleep disorders. Intentional tremor: It is a tremor that appears during random movements. It is characterized as being most pronounced during purposeful movements or when the target is about to be reached, and is commonly seen in lesions of the cerebellum and its efferent pathways. Intentional tremor may not be accompanied by hypotonia and only occurs during limb movements. Myotonic tremor: It is a spontaneous discharge of one or more motor units during muscle rest that causes muscle tremor in the form of a transient single contraction, and is seen in various lower motor neuron injury disorders and in some normal individuals. EMG examination shows spontaneous potentials and normal nerve conduction velocity. Soft and firm herbs are used internally and externally, together with acupuncture and massage.
