Abstract:[Objective] To observe the clinical consequences of orientational muscle group guided training (OMGGT) in the early reha- bilitation of total hip arthroplasty (THA). [Methods] A total of 60 patients who were undergoing THA in our hospital from October 2021 to October 2022 were enrolled into this study and randomly divided into the two groups. Of them, 30 patients in the training group received OMGGT, while other 30 patients in the conventional group received the conventional rehabilitation training after surgery. The clinical data were compared between the two groups. [Results] All patients in both groups had THA performed successfully without serious complica- tions. The VAS for pain, Harris scores, hip range of motion (ROM) and performance-oriented mobility assessment (POMA) improved signifi- cantly over time in both groups (P<0.05). One month postoperatively, the training group proved significantly superior to the conventional group in terms of VAS score [(0.9±0.7) vs (3.3±0.9), P<0.001], Harris score [(81.8±5.8) vs (67.2±4.3), P<0.001], hip ROM [(94.6±9.9) vs (77.2±7.4), P<0.001] and POMA score [(25.3±1.4) vs (21.5±1.1), P<0.001]. [Conclusion] The orientational muscle group guided training does improve hip function recovery after total hip arthroplasty, increase the hip muscle strength and balance ability, improve the patient's ambulation adaptability.
