A Clinical Controlled Study of Focused Shock Wave Therapy under Ultrasound Localization in the Treatment of Waist and Buttocks “Ashi Point”

Objective: To compare the short-term and long-term effects of focused shock wave and traditional acupuncture on Ashi points in waist and buttocks under ultrasonic positioning. Methods: 60 patients were randomly divided into treatment group (focused shock wave, n=30) and control group (traditional acupuncture, n=30). The main evaluation indexes were ultrasonic Young’s modulus (tissue hardness) and VAS pain score. The evaluation time points were before treatment, immediately after treatment and 90 days after treatment. Result: The reduction of Young’s modulus (Δ value) and the improvement of VAS score in the treatment group were significantly better than those in the control group (p<0.05). Conclusion: Focused shock wave under ultrasound localization has more advantages in accurately targeting treatment points, improving tissue mechanical properties and long-term analgesic effects.
