Study Objectives: To determine the immediate effects of a single session of MWM on hip pain in people with hip OA. The secondary objective was to evaluate the immediate effects of MWM on hip ROM and physical performance in these subjects. Design: A double blind randomized placebo controlled trial. Setting: Subjects were taken from Out patient Physiotherapy Dept. of Jaipur Physiotherapy College, Maharaj Vinayak Global University Jaipur and different hospitals in Jaipur. Methods: A total of 40 subjects were recruited for the study on the basis of inclusion and exclusion criteria after signing the informed consent form. The subjects were randomly allocated into two Groups (experimental (MWM group) and placebo (sham intervention group). Outcome Measure: Pain thresh hold was measured using NPRS (Numeric Pain Rating Scale), Hip flexion and internal rotation ROM, The Timed Up and Go (TUG) test, The 30s Chair Stand (CS) test, The 30s Chair Stand (CS) test. Result: We took the baseline and post-intervention data as well as within-group and between-groups differences for hip pain, hip ROM and functional tests. The intensity of pain (F = 29.06, P < 0.01). 16 patients receiving MWM, in contrast to 2 patients receiving sham mobilisation, experienced a decrease in hip pain more than the MDC of 0.83. A significant Group by Time interaction was detected for hip flexion (F = 74.13; P < 0.01) and hip internal rotation (F = 18.38; P < 0.01) ROM. An ANOVA also revealed a significant Group by Time interaction for all functional tests (TUG: F = 10.00, P < 0.01; CS: F = 29.46, P < 0.01; SPW: F = 23.80, P < 0.01). Conclusion: This study showed that pain immediately decreased, hip flexion and internal rotation ROM and physical function improved after a single session of hip MWM in elderly subjects suffering hip OA. Although the observed immediate changes are greater than the MDC and previous reports for MCID, more research is necessary to determine long-term efficacy.
