Objectives: To investigate the influence of motor control training of deep external rotators of hip joint on pain and function followed by Total Hip Replacement (THR). Methods: Subjects (n=10) who had posted for unilateral Total Hip Replacements were enrolled. Pre and post intervention data collected from 10 patients, who were posted for total hip replacement. Patient’s received motor control training for deep external rotators of hip joint, twice a day for 8 weeks along with standard THR rehabilitation exercises. Thirty second chair stand test is used as primary outcome measure and NPRS, HOOS and Timed Up and Go test are used as secondary outcome measures. All the outcome measures have taken pre and post 8 weeks of intervention. Paired t-test used for statistical analysis to find out the changes within the group. Results: Overall significant differences were observed before and after the training in all outcomes. 30 sec chair stand test improved by mean of 2.60 ± 1.35 times (p=0.001). NPRS demonstrated a reduction in pain score from 8.90 (0.99) to 2.30 (0.82) with a mean of 5.60 ± 0.96. Timed Up and Go test showed an improvement of 8.10 sec over an 8 weeks from 29.60 sec to 21.50 sec (p=0.003). HOOS total score showed a better shift from 98.89 ± 16.59 to 52 ± 8.92 in 8 weeks. Conclusion: The implementation of motor control training of deep external rotators of hip joint along with standard THR protocol following unilateral Total Hip Replacement improves pain scores and physical function post 8 weeks of surgery.
