About this study
Official title: Effects of Perturbation-Based Balance Training on Balance Ability and Fall Efficacy in Patients After Total Hip Arthroplasty: A Randomized Controlled Trial
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.
Read the detailed description
Total hip arthroplasty (THA) is commonly performed to reduce pain and improve functional mobility in patients with hip joint disorders. However, many patients continue to experience impaired balance control, decreased proprioception, muscle weakness, and fear of falling after surgery. These impairments may negatively affect gait stability, activities of daily living, and quality of life.
Traditional balance training programs mainly focus on static posture control and predictable weight-shifting tasks. However, such approaches may not adequately improve reactive postural control required for unexpected balance disturbances encountered during daily activities. Perturbation-based balance training (PBT) has recently gained attention as an intervention designed to improve reactive balance control by exposing individuals to unexpected external disturbances and encouraging adaptive postural responses.
This study aims to investigate the effects of perturbation-based balance training using pressure biofeedback in patients following total hip arthroplasty. The pressure biofeedback system provides controlled instability and real-time sensory feedback during balance tasks, allowing participants to improve postural control strategies and weight-shifting ability.
Thirty patients who underwent THA will be recruited and randomly assigned to either an experimental group or a control group. The experimental group will receive perturbation-based balance training using pressure biofeedback in addition to conventional physical therapy, while the control group will perform conventional balance training with conventional physical therapy. Interventions will be performed 5 times per week for 6 weeks.
Outcome measures will include balance performance assessed by the Berg Balance Scale (BBS), Functional Reach Test (FRT), and center of pressure (COP) parameters measured using a Wii Balance Board. Falls efficacy will be evaluated using the Falls Efficacy Scale (FES). Hip function and lower extremity function will be assessed using the Harris Hip Score (HHS) and Lower Extremity Functional Scale (LEFS).
The findings of this study may provide evidence supporting the clinical applicability of perturbation-based balance training using pressure biofeedback as an effective rehabilitation strategy for improving postural stability and reducing fall risk after THA.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
pertubation based on balance trainingBehavioural
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.
Traditional Balance TrainingBehavioural
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.
| Study group | Role | What they receive |
|---|---|---|
| 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. Receives: 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. Receives: Behavioral: Traditional Balance Training |
What is being measured
The primary outcome is the main question the study is designed to answer.
Berg Balance Scale (BBS)
Functional balance assessed with the Berg Balance Scale, a 14-item performance-based scale scored from 0 to 56, with higher scores indicating better balance.
Measured: Baseline and after 6 weeks of intervention
Secondary outcomes (4)
Functional Reach Test (FRT)
Maximum forward reach distance in centimetres while standing, measured with the Functional Reach Test; greater distance indicates better dynamic balance.
Measured: Baseline and after 6 weeks of intervention
Falls Efficacy Scale (FES)
Fall-related self-efficacy assessed with the Falls Efficacy Scale; higher scores indicate greater confidence in performing activities without falling.
Measured: Baseline and after 6 weeks of intervention
Harris Hip Score (HHS)
Hip function assessed with the Harris Hip Score, covering pain, function, deformity and range of motion, scored from 0 to 100, with higher scores indicating better hip function.
Measured: Baseline and after 6 weeks of intervention
Lower Extremity Functional Scale (LEFS)
Lower-limb function assessed with the Lower Extremity Functional Scale, a 20-item self-report questionnaire scored from 0 to 80, with higher scores indicating better function.
Measured: Baseline and after 6 weeks of intervention
