Too much muscle tension in the arm after cerebral infarction can be relieved by warming therapy, pulling spastic muscle groups and guiding active movement. 1. Warming therapy: using physical methods such as warm water, microwave, ultrasound, etc., to make the stiff muscles and joints become more supple, so as to reduce pain and numbness. 2. Pulling spastic muscle groups: that is, pulling spastic muscle groups to the appropriate length and then holding them for a certain period of time to reduce their overly strong pulling reflexes. The stretching should not be excessive, as excessive stretching will aggravate the dysfunction of patients with cerebral infarction. The specific operation method is to pull in the direction opposite to the muscle spasm, until there is just resistance and then slowly increase 10~20 degrees, and keep it for 1~3 minutes each time. 3. Guiding active movement: patients with cerebral infarction should carry out active movement to strengthen the muscle strength of antagonist muscles and pull spastic muscles at the same time. In addition, you can also use muscle relaxants such as baclofen and botulinum toxin injection to reduce muscle tension and improve pain symptoms. There are various ways to relieve hypertonia, and patients are advised to consult their doctors in time to choose the right one.
