The aim of this study was to investigate the efficacy of the Yumeiho therapy massage on repositioning error, Range of motion in trunk flexion and functional power in women volleyball players with Hyper lordosis.  Methods:  the present study was a quasi - experimental study with a pretest-posttest design with a control group. A total of 30 postmenopausal women with hyper lordosis were purposefully selected and randomly divided into two groups of 15 individuals: a treatment and control groups. The amount of repositioning error and range of motion by spinal mouse and muscle strength was calculated by dynamometer. The experimental group strength training did three times a week for eight weeks. Paired samples t-test was run for within group comparisons and independent sample t-test was used for between group comparisons. Results: Significant differences were observed between the two groups in the repositioning error, Range of motion of trunk flexion and extensor and flexor of trunk muscle. Conclusion: Results showed that Yumeiho therapy massage would have a significant effect on repositioning error, flexion range of motion trunk and the functional power.
