Sensory function and motor function are closely related, and the presence of sensory loss, retardation, and hypersensitivity can seriously affect motor function. (A) basic principles of sensory training 1, correct abnormal muscle tension to normalize it; inhibit abnormal posture and pathological movement patterns. 2.When applying sensory stimulation, the spasm caused by the stimulation must be prevented from aggravating. 3.To obtain the best therapeutic effect, the cooperation of the patient must be obtained. 4.The therapist and the patient should be fully prepared for the fact that the recovery of sensation cannot occur in a short period of time. 5, the same action or the same stimulation need to be repeated several times, but also pay attention to not frequently change the training tools. 6, according to the patient’s degree of sensory impairment to choose the appropriate training methods and training tools, training should be gradual, from easy to difficult, from simple to complex. Such as placing a round ball and a square block of wood in the wooden box, instruct the patient to judge the ball and the square block; after the patient’s judgment is more accurate, then place three large, medium and small round balls or square blocks of wood in the wooden box, instruct the patient to touch with the affected hand to judge the difference between them. Patients with sensory impairment, in addition to making motor function more affected, loss of sensation or retardation is also easy to cause burns, trauma, infection, etc. The therapist should help the patient to develop the habit of using visual compensation in treatment and daily life to prevent accidental injury. (2) Training with obvious sensory impairment In the recovery period of hemiplegia, training of sensory function should be added at the same time. When the patient grasps the wood, the sensory stimulation of various materials on the patient’s periphery and the participation of vision can improve the perceptual ability of the central nervous system. 2, weight training of the affected upper limb is one of the training methods to improve the motor function of the upper limb. When the affected upper limb is weighted, different materials can be laid under the support surface, such as wood, metal, cotton, velvet, etc., which invariably exerts a variety of sensory stimulation on the palm. (C) Sensory-motor training for deep sensory disorders Deep sensory disorders are mainly reflected in position perception disorders and kinesthetic disorders, which must be combined with training. Initially, the therapist guides the patient to make and experience correct movements through passive movements, and then instructs the patient to use the healthy side to guide the affected side to complete these movements, and furthermore, indirectly guides the affected upper limb to make correct movements by lifting larger objects with both hands. Writing exercises are also an effective training element. At first, it is easier to draw lines and smooth curves than straight lines as required. When the patient can use the pen better, the patient can be instructed to write the words in the grid using a line grid paper.
