[Clinical observation on therapeutic effect and instant analgestic effect of inhibitory-needling at Ashi point as major point for treatment of piriformis syndrome].

Objective: To observe therapeutic effect and analgesic eJfect of needling at Ashi point for treatment of piriformis syndrome.

Methods: Eighty cases were randomly divided into an inhibitory-needling method group (INM) and a routine-needling method group (RNM), forty cases in each group. The acupuncture at Ashi point as major point with inhibitory-needling munipulation was applied in the INM group, the acupuncture at Huantiao (GB 30) ,Zhibian (BL 54) ,Yanglingquan (GB 34) with routine-needling method in the RNM group. The therapeutic effect, the instant analgesic effect and score of Visual Analogue Scale (VAS) were observed.

Results: After treatment, the effective rate of 92.5% in the INM group was better than that of 82.5% in the RNM group (P < 0.05); the instant analgesic effect rate of 75.0% in the INM group was better than that of 52.5% in the RNM group (P < 0.01); the score of VAS in both groups had decreased with a significant difference between two groups (P < 0.05).

Conclusion: The treatment of inserting the needle at Ashi point as major point with inhibitory-needling method has excellent effectiveness and good instant analgesic effect, with fewer points selection and rapid effect.
