Objective To study the effect of point⁃through⁃point acupotomy on the range of shoulder joint motion and its long⁃term clinical effect on frozen periarthritis of shoulder. Methods Sixty patients with frozen peri⁃ arthritis of shoulder in our hospital were randomly divided into two groups using the random number table method： point⁃through⁃point acupotomyacupotomy group（n = 30）and traditional acupotomy group（n = 30）. The treatment cycle for both groups was once a week，4 times as a course of treatment. The clinical efficacy，VAS，range of shoulder joint motion（ROM）and shoulder function（Constan⁃Murley）of the two groups were evaluated on the first day after the treatment，the first month after the treatment，and the third month after the treatment. Results After the treatment，the total effective rate of the point⁃through⁃point acupotomy group was significantly higher than that of the traditional acupotomy group（P < 0.05）. The VAS scores of the two groups were significantly lower than those before the treatment respectively（P < 0.05）. The VAS score of the point⁃through⁃point acupotomy group was significantly lower than that of the traditional acupotomy group（P < 0.05）. The ROM of extension，flexion，adduc⁃ tion，abduction，and external rotation in the two groups were significantly higher than those before the treatment respectively（P < 0.05）. In addition，the extension，flexion，adduction，abduction and external rotation ROM of patients in the point⁃through⁃point acupotomy group were significantly higher than those in the traditional acupoto⁃ my group（P < 0.05）. Conclusion The point⁃through⁃point acupotomy is effective in treating frozen periarthritis of shoulder by reducing the degree of pain，improving the function and range of motion of shoulder joint，and ele⁃ vating the short⁃term and long⁃term rehabilitation of frozen periarthritis of shoulder.
