简要总结
Task-oriented leg exercise are commonly used after joint surgeries in various hip pathologies. Based on this theory, it was hypothesized that task-oriented exercise without conventional physiotherapy can have better result in recovery of balance and leg function than with a conventional post-hip physiotherapy program after hip replacement surgery. The aim of the study was to determine the effect of task-oriented exercise on balance and leg function after total hip replacement.
详细描述
Study included 40 subjects. All subjects were randomly divided into control and intervention groups. VAS scale was used to assess the pain, hip range of motion were measured using a goniometer, strength of the muscles was assessed on the Oxford 5 point scale, leg function was evaluated with modified Harris hip scale, Abili balance analyzer was used to assess static balance and Berg balance scale was used to measure dynamic balance. Intervention duration was 18 days.

研究组 & 干预措施
Control group
Conventional physiotherapy was applied 5 days/ week, 30 min session, in total 18 days.
Exercise program:
- 1-2 week: 20 min. of active exercise in lying position (e.g.: hip flexion, extension, abduction) with the goal to improve hip range of motions, strengthen muscles. Various equipment was used (slippery base, elastic bands, foam roller, gymnastic ball etc.). + gait training exercise within the bars (10 min);
- 3 week: 20 min. of active exercise in lying position + stationary bicycle / treadmill (10 min).
干预措施: Control (Other)
Task oriented exercise group
Task oriented exercise program was applied 5 days/ week, 30 min session, in total 18 days.
Exercise program included:
- 1 week: active exercise in lying position (15 min) + task-oriented exercise (15 min);
- 2 week: active exercise in lying position (10 min) + task-oriented exercise (20 min);
- 3 week: stationary bicycle / treadmill (10 min) + task-oriented exercise (20 min).
Task oriented exercise included:
- walking backwards, sideways, high kneels (on the instable bases);
- walking with alternate speed (physiotherapist give the instruction when to walk faster / slower);
- Sit and stand from the chair (standing up to reach for the ball held by the physiotherapist);
- step onto the step (after stepping to reach the ball held by the physiotherapist);
- walk with the obstacles (obstacle course);
- Catch and throw the ball while standing on an unstable base.
干预措施: Task-oriented exercise (Other)
结局指标
主要结局
Change from baseline Pain at 18 days
时间窗: Baseline and after 18 days
was evaluated using the Visual Analogue Pain Scale (VAS). Participants were asked to report "current" pain intensity. A higher score indicates greater pain intensity: no pain (0-4 mm), mild pain (5-44 mm), moderate pain (45-74 mm), and severe pain (75- 100 mm).
Change from baseline Hip range of motions at 18 days
时间窗: Baseline and after 18 days
Using goniometer the range of hip motions were evaluated: flexion, extension, abduction. Each motion was measured three times and averaged value was used.
Change from baseline Hip Muscle Strength at 18 days
时间窗: Baseline and after 18 days
The muscle strength of hip flexion, extension, and abduction was evaluated using manual muscle testing technique (Oxford 5 point scale).
Change from baseline Leg Function at 18 days
时间窗: Baseline and after 18 days
To evaluate the function of leg after hip replacement surgery the modified Harris Hip Score (mHHS) was used. MHHS is reliable and valid tool to evaluate leg function after hip replacement and to monitor the leg function during recovery. The questionnaire was completed by a physiotherapist together with the patient. This questionnaire consists of 8 questions / topics, where each answer has a score: * Pain description (maximum 44 points); * Limping (max 11 points); * Assistive devices (max 11 points); * Walking distance (max 11 points); * Stair climbing (max 4 points); * Putting on shoes/socks (max 4 points); * Sitting (max 5 points); * Using public transport (1 point). The higher the score, the better the leg function. The maximum number of points is 91.
Change from baseline Dynamic Balance at 18 days
时间窗: Baseline and after 18 days
Dynamic Balance was assessed using the Berg Balance Scale (BBS). This scale is used to assess the subjects' imbalance in 14 different tasks, where each task is scored on a scale from 0 (does not perform at all) to 4 (performs excellent). The higher the score, the better the balance, with a maximum score of 56.
Change from baseline Static Balance at 18 days
时间窗: Baseline and after 18 days
Static Balance was assessed using the "Abili balance analyzer system". Abili balance analyzer is a platform that can be adapted for both patient testing and training. The Abili analyzer system consists of two parts: the Abili analyzer platform and the Balance trainer app. The Abili analyzer platform plate moves in a horizontal plane, making it safe to use for patients of all capacities. Thus, using this balance platform, three levels of difficulty can be selected: light, medium and advanced, as well as the handles are adjustable according to the patient's height. After three tests, the gadget calculates a total stability index. The lower the number, the better the stability and the lower the fluctuation.
