Abstract: ObjectiveTo observe effect of combined treatment for piriformis syndrome and analyze its cause, pathoge nesis, pathology and recovery mechanism.Methods73 piriformis syndrome cases were divided randomly into two groups. The control gro up (35 cases) was given routine treatment, but the treatment group (38 cases) ad ded with thermal therapy, computerized medium frequency electrotherapy, manual t herapy, etc. After two courses, therapeutic effects were observed and assessed w ith standards for hip joint function.Results Of the control group,14 cases were cured,9 effectual,9 effective, and 3 ineffecti ve; of the experiment group, 23 cured,9 effectual, 5 effective, and 1 ineffecti ve. By statistical analysis, the therapeutic effect in the treatment group is su perior to those in the control group (P<0.05). Hip joint fu nction is assessed by scores as: the median point before and after the treatment for the control group is 18.00,the experiment group is 27.50, with statistical ly significance difference (P<0.01).The average cure time f or the experiment group is 11.04±5.10 days, fewer than that for the control gro up (14.79±5.79 days)(P<0.05).Conclusions Comb ined treatment used for piriformis syndrome can produce remarkable therapeutic e ffect, and various types of therapies can play such coordinate roles as promotin g blood circulation, repercussion, anti-inflammation, analgesia, relaxing adhes ion and softening scar.
