Objective: To find out the effects of Muscle Energy Technique of piriformis and iliopsoas improve pain, disability, and pain free sitting duration in females with coccydynia.

Materials and Methods: It was a single blinded, randomized clinical trial on females with coccydynia.

Fifty-two participants were randomly allocated into two group i.e.  METs= 26 and Static stretching group = 26, by simple random sampling. METs group received post isometric relaxation of piriformis and iliopsoas and static stretching group received stretching for 10 sessions. Participants were assessed at baseline and after 2 weeks for 10 sessions (5 days per week).  Outcome measures were taken on NPRS, Modified Dallas Pain Questionnaire and pain free sitting duration.

Results: Data was analyzed via SPSS. The mean difference of NPRS between groups was 2.36 (95% Cl). There was greater reduction in pain (6.84>4.48) in METs. The mean difference was 1.26 (95% Cl) on DPQ.  There was marked improvement in pain free sitting duration from 49.68mintues to 87.04. (95% Cl) between METs and Static stretching group.

Conclusion: Muscle energy technique is more effective as compared to static stretching method in reducing pain and improving pain free sitting duration and effects of METs are long lasting in improving pain free sitting duration.
