1, relaxation training explanation: explain to patients the principles, characteristics and operational considerations of relaxation training, establish treatment goals and motivate patients to participate actively. (1) Progressive muscle relaxation training method (PMR, first founded by American physiologist Edmund Czech Boison in the 1930s, later gradually improved and widely used, is a good relaxation method at present. (2) Progressive muscle relaxation training method is based on the theory that an individual’s mood consists of both “emotional” and “somatic” aspects. If the “somatic” response can be changed, the “emotional” response will be changed as well. Visceral somatic reactions are mainly influenced by the subcortical center and the autonomic nervous system, which are not easily manipulated and controlled; while the central and somatic nervous systems can control the activities of the “casual muscles” and indirectly relax emotions by consciously controlling the activities of the casual muscles, so as to establish and maintain a relaxed and happy emotional state. (3) The specific practice is through the repeated alternating training of contraction-relaxation of the main muscles of the body, so that people can experience the different sensations of tension and relaxation, so as to better understand the tension response and relaxation, and finally achieve the purpose of physical and mental relaxation, which can play a role in adjusting the functions of various organs of the body. (4) Note: After the progressive muscle relaxation training method, you will generally feel clear-headed, calm, comfortable and energetic. Some scholars believe that these feelings are the adjustment of the autonomic nervous system, and the release of abnormal energy accumulation in the central nervous system, which is the best reflection of the effect of progressive muscle relaxation training method. 2, implementation: take a sitting or lying position, in a state of calm breathing, from top to bottom, alternating tension and relaxation, and finally achieve the purpose of relaxing the whole body muscles and stabilizing emotions. In the specific implementation, let the patient combine their physical condition, appropriate to give up some difficult to do steps, do not need to complete the training in order to cause unnecessary burden. 3.Guiding words (to be clear, low, gentle and pleasant, accompanied by movement demonstration) “I am now going to teach you how to make yourself relax. In order to do this, I will let you first tense, and then relax the muscles of the whole body. The point of tensing and relaxing is to make you experience the feeling of relaxation so that you can learn how to stay loose.” Step 1: “Take a deep breath in and hold it for a moment.” (Pause for 10 seconds) “Okay, please breathe out slowly, slowly.” (Pause for 5 seconds) “Now let’s do it again.

Please follow the instructions of the instrument for operation.
