“A study observed the effect of exercise scalp acupuncture on H-reflex changes in post-stroke spasticity (PSS) rats and explored its electrophysiological mechanism against PSS. Research has found that the head acupuncture technique can effectively improve neurological function damage, reduce spastic muscle movement threshold, Hmax/MMax ratio, and H-reflex FDD, and exert a good anti PSS effect. This discovery provides new ideas and methods for the treatment of PSS, and has important clinical value. This study used male SD rats as experimental subjects and prepared a middle cerebral artery occlusion model using an improved suture method. The rats were randomly divided into a sham surgery group, a model group, and a exercise scalp acupuncture group. After 7 consecutive days of treatment, researchers found significant changes in nerve function damage, muscle tone, and motor function in the model group rats, while the exercise scalp acupuncture group showed the opposite results. This result indicates that the exercise needle method has a significant anti PSS effect. In addition, researchers also recorded the changes in H-reflex in each group of rats and found that the frequency dependent suppression (FDD) of H-reflex in the model group was significantly increased, while the exercise scalp group showed the opposite trend. This discovery further confirms that the head acupuncture technique can improve neurological damage, reduce spastic muscle movement threshold, Hmax/MMax ratio, and H-reflex FDD, thereby exerting anti PSS effects. This study not only provides new ideas and methods for the treatment of PSS, but also provides strong support for the application and development of the exercise scalp acupuncture method. In the future, we can further explore the clinical application of exercise scalp acupuncture, bringing good news to more patients.”
