[Impact of abdominal moxibustion in a period of day from 7 am to 9 am on improvement in post-stroke lower limb spasticity and muscle architecture parameter]

To compare the therapeutic effect on post-stroke lower limb spasticity between the combined treatment of abdominal moxibustion from 7 am to 9 am and rehabilitation training and the simple rehabilitation training.A total of 100 patients with post-stroke lower limb spasticity were randomized into an observation group (50 cases, 3 cases dropped off) and a control group (50 cases, 4 cases dropped off ). In the control group, the basic treatment of internal medicine and rehabilitation training of the limbs were adopted. In the observation group, on the basis of the treatment in the control group, at the time zone from 7 am to 9 am, moxibustion on the abdomen with "eight-trigram" moxa box [the central moxa box accurately facing Shenque (CV 8)] was given, lasting for 2 h, once every two days. Both groups were treated for 6 weeks. Separately, before and after treatment, the score of Fugl-Meyer assessment of the lower extremity (FMA-LE) and the grade of modified Ashworth scale (MAS) of ankle joint were evaluated on the affected side in patients of the two groups. Muscle skeleton ultrasound (MSUS) was adopted to determine the first layer muscle thickness (MT) anterior to the tibia, the number of pennation angle (PA) and the length of muscle fibers in the medial head of gastrocnemius muscle on the affected side. Besides, after treatment, the therapeutic effect was evaluated in the two groups.After treatment, the score of FMA-LE and the grade of MAS of ankle joint on the affected side were both improved as compared with those before treatment in patients of the two groups (The combined treatment of abdominal moxibustion from 7 am to 9 am and rehabilitation training effectively relieves post-stroke lower limb spasticity and improves the limb functions and muscle structure. The total effective rate of this combined treatment is better than that of simple rehabilitation training.
