Observation of the Therapeutic Effect of Fire Needle on Upper Limb Function in Stroke Patients

105 patients with upper limb dysfunction after stroke were selected according to the inclusion criteria and randomly divided into an extensor treatment group, a flexor treatment group, and a control group of 35 cases each. The patients in the extensor treatment group were treated with routine rehabilitation training+routine acupuncture and moxibustion+millifire needle acupuncture for the extensor muscle group (triceps brachii, forearm extensor muscle group), the patients in the flexor treatment group were treated with routine rehabilitation training+routine acupuncture and moxibustion+millifire needle acupuncture for the flexor muscle group (biceps brachii, forearm flexor muscle group), and the patients in the control group were treated with routine rehabilitation training+routine acupuncture and moxibustion+routine millifire needle acupuncture. The treatment was administered once every other day with a moxibustion needle for a total of 4 weeks. Observe the upper limb movement trajectory, surface electromyographic signals (sEMG) of extensor and flexor muscle groups, changes in MAS scale scores, and FMA-UE scores of two groups of patients under specific tasks detected by a three-dimensional motion capture system before, after one treatment, and after 4 weeks of treatment. Calculate joint angles and motion distances through spatial coordinates, and apply RMS MF、CC、 Coherence analysis quantifies muscle strength, muscle tension, fatigue, and coordination.
