Effects of Lower Limbs Symmetrical Loading on Risk of Fall

Study Overview
=================
Brief Summary
-----------------
Objective: To assess the impact of total hip arthroplasty (THA) on functional outcomes and fall risk in patients with hip osteoarthritis. The objective was to investigate the effectiveness of physical therapy in postoperative rehabilitation and identify fall risk factors to guide fall prevention strategies after THA. Methods: A non-randomized, interventional clinical trial was conducted with 30 patients scheduled for THA. Functional outcomes were evaluated using the Harris Hip Score (HHS), 40-meter fast-paced walk test (40mFPWT), 30-Second Chair Test, and Western Ontario McMaster Universities Osteoarthritis Index (WOMAC). Balance and fall risk were assessed using the Single-Leg Standing Test and a posturography device (TETRAX). The Nottingham Health Profile (NHP) was used to measure subjective health status and quality of life. Assessments were performed preoperatively, at 6 weeks postoperatively, and at 3 months postoperatively.

| Experimental: experimental group<br>30 patients who underwent total hip arthroplasty surgery took part in the experimental group. | Other: postoperative rehabilitation<br>* 30 patients took postoperative rehabilitation after total hip arthroplasty surgery, 3 times a week, for 6 weeks. They took conventional rehabilitation (hip range of motion exercises, progressive strengthening exercises for hip and knee muscles, balance and proprioceptive exercises and gait training).<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Harris Hip Score (HHS) | min-max (0-100) Results can be interpreted with the following: <70 = poor result; 70-80 = fair, 80-90 = good, and 90-100 = excellent. | preoperative, postoperative 6 weeks and 3 months | 
| 40-meter fast-paced walk test |  | preoperative, postoperative 6 weeks and 3 months | 
| 30-Second Chair Test |  | preoperative, postoperative 6 weeks and 3 months | 
| Western Ontario McMaster Universities Osteoarthritis Index (WOMAC) | It is a self-administered questionnaire consisting of 24 items divided into 3 subscales: Pain, Stiffness, Physical Function. Higher scores on the WOMAC indicate worse pain, stiffness, and functional limitations. | preoperative, postoperative 6 weeks and 3 months | 
| Static balance and fall risk | It was assessed with Posturography device (TETRAX) | preoperative, postoperative 6 weeks and 3 months | 
| Single-Leg Standing Test |  | preoperative, postoperative 6 weeks and 3 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The Nottingham Health Profile (NHP) | The NHP is composed of 38 items divided into six domains: Sleep Mobility Energy Pain Emotional reactions Social isolation Items use a Yes/No answer format. Each item is weighted. NHP scores are calculated by averaging domain scores. Total scores range from 0 (no perceived distress) to 100 (maximum perceived distress). | preoperative, postoperative 6 weeks and 3 months |
