Brief Summary

This randomized controlled study aims to investigate the effects of perturbation-based balance training using pressure biofeedback on balance ability, hip function, and falls efficacy in patients after total hip arthroplasty (THA). Thirty participants who underwent THA will be randomly assigned to either a perturbation-based balance training group or a conventional balance training group. Both groups will receive intervention five times per week for 6 weeks in addition to conventional physical therapy. Outcome measures include Berg Balance Scale, Functional Reach Test, Falls Efficacy Scale, Harris Hip Score, Lower Extremity Functional Scale, and center of pressure (COP) parameters. The study is expected to provide clinical evidence for improving balance control and reducing fall risk in patients after THA.

Pressure Biofeedback-Based Perturbation Balance Training Group

EXPERIMENTAL

Participants will receive perturbation-based balance training using pressure biofeedback in addition to conventional physical therapy. The intervention will be conducted for 15 minutes per session, five times per week, for six weeks.

Behavioral: pertubation based on balance training

Conventional Balance Training

ACTIVE COMPARATOR

Participants performed traditional balance training combined with conventional physical therapy. Training included static and dynamic balance exercises, weight shifting, postural control tasks, and functional reaching activities without pressure biofeedback. The intervention was conducted for 30 minutes per session, 5 sessions per week, for 6 weeks.

Behavioral: Traditional Balance Training

Interventions

pertubation based on balance training BEHAVIORAL

Participants performed perturbation-based balance training using pressure biofeedback devices in addition to conventional physical therapy. During standing tasks, pressure biofeedback units were placed under both feet, and temporary instability was induced by adjusting air pressure to alter support surface stability. Participants performed progressive balance tasks including static standing, weight shifting, multidirectional reaching, and PNF-based reaching patterns. Training intensity and task difficulty were progressively increased according to participant performance. The intervention was conducted for 15 minutes per session, 5 sessions per week, for 6 weeks under therapist supervision.

Pressure Biofeedback-Based Perturbation Balance Training Group

Traditional Balance Training BEHAVIORAL

Participants in the control group received traditional balance training without pressure biofeedback. The intervention included static and dynamic balance exercises, postural control training, weight-shifting tasks, and posture transition activities. The training tasks were performed in the same sequence and progression as the experimental group, but without perturbation induced by pressure biofeedback devices. Participants received training for 30 minutes per session, 5 times per week, for 6 weeks in addition to conventional physical therapy.
