title: [Comparative study on curative effects of stroke treated with acupuncture by NIRS].
abstract: OBJECTIVE
  To compare the intracephalic imaging differences of stroke treated with combined therapy of scalp and body acupuncture and body acupuncture only, in order to apply the image basis for the differences of clinical curative effects.
  
  
  METHODS
  Twenty cases of stroke were randomized into a body acupuncture group (group A) and a scalp and body acupuncture group (group B), ten cases in each group respectively. In group A, body acupuncture was applied simply, and different acupoints were selected according to the symptoms: Shousanli (LI 10), Jianliao (TE 14), Huantiao (GB 30) and Jiaji (EX-B 2) etc. were selected for hemiplegia, Fengchi (GB 20), Xiaguan (ST 7) and Quanliao (SI 18) etc. were for facial paralysis, Fengfu (GV 16) and Lianquan (CV 23) etc. were for aphasia. In group B, combined therapy were applied, the body acupoints selection was same as above; for scalp acupoints, corresponding motor area, sensory area and foot motor sensory area were selected. Instant changes of local cerebral blood flow before and after treatment were examined and evaluated by NIRS and the curative effects of both groups were evaluated.
  
  
  RESULTS
  The total therapeutic effective rate was 90.0% (9/10) and the basically cured rate was 30.0% (3/10) in group A; and 100.0% (10/10) and 50.0% (5/10) respectively in group B, indicating that the clinical curative effect in group B was superior to that in group A at 20, 30 min of acupuncture treatment (P < 0.05). Both imaging results showed that blood flows of prefrontal cortex in both groups were increased with varying degrees after treatment (P < 0.05, P < 0.01); the cerebral blood flow in group B was much more improved than that in group A at 20, 30 min of acupuncture treatment (all P < 0.05).
  
  
  CONCLUSIONS
  Acupuncture can significantly increase blood flow and oxygen saturation in brain cortex, and the effect with combined therapy of scalp and body acupuncture is superior to that with body acupuncture.
