About

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.

Full description

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.

40 participants in 2 patient groups

Control group

Active Comparator group

Description:

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).

Treatment:

Other: Control

Task oriented exercise group

Experimental group

Description:

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.
