Dual-Task Balance Training in Traumatic Lower-Limb Prosthesis Users (DTBT-LLA)

22 juli 2026 bijgewerkt door: Rawan Nabil Alessi, Al-Azhar University - Gaza

Effectiveness of Dual-Task Balance Training on Balance, Mobility, and Mental Health Among Traumatic Lower-Limb Prosthesis Users in the Gaza Strip: A Randomized Controlled Trial

This randomized controlled trial will evaluate the effectiveness of dual-task balance training on balance, mobility, and mental health among traumatic lower-limb prosthesis users in the Gaza Strip. Participants will be randomly assigned to either an experimental group receiving dual-task balance training in addition to standard rehabilitation or a control group receiving standard rehabilitation only. The intervention will be delivered over 6 weeks, with three sessions per week. Balance and mobility will be assessed using the Berg Balance Scale and the Amputee Mobility Predictor with Prosthesis, while mental health will be assessed using the Depression, Anxiety, and Stress Scale-21.

Gedetailleerde beschrijving

Lower-limb amputation can lead to significant impairments in balance, mobility, functional independence, and psychological well-being. Prosthesis users often experience challenges during walking and daily activities, particularly when they are required to perform a motor task and a cognitive task at the same time. Dual-task balance training is a rehabilitation approach that combines balance exercises with concurrent cognitive or motor tasks to improve postural control, mobility, attention, and functional performance.

This study is a parallel-group randomized controlled trial designed to investigate the effectiveness of dual-task balance training among traumatic lower-limb prosthesis users in the Gaza Strip. Eligible participants will be traumatic transtibial or transfemoral lower-limb prosthesis users who meet the study inclusion criteria and provide informed consent.

Participants will be randomly allocated into two groups. The experimental group will receive dual-task balance training in addition to standard rehabilitation. The control group will receive standard rehabilitation only. The dual-task balance training program will be conducted for 6 weeks, with three sessions per week. Training will include progressive balance activities combined with cognitive or motor secondary tasks, according to the participant's ability and safety level.

The primary outcomes of the study are balance and mobility, measured using the Berg Balance Scale and the Amputee Mobility Predictor with Prosthesis. The secondary outcome is mental health, measured using the Depression, Anxiety, and Stress Scale-21. Outcome measurements will be collected before and after the intervention period by an assessor who is not involved in delivering the intervention.

The study aims to provide evidence on whether adding dual-task balance training to standard rehabilitation can improve balance, mobility, and mental health outcomes among traumatic lower-limb prosthesis users in a resource-limited rehabilitation setting.

Primaire uitkomstmaten

Uitkomstmaat
Maatregel Beschrijving
Tijdsspanne
Change in Balance as Assessed by the Berg Balance Scale
Tijdsspanne: Baseline (Day 0) and Week 6
Balance will be assessed using the Berg Balance Scale (BBS), which consists of 14 functional balance tasks. The total score ranges from 0 to 56, with higher scores indicating better balance performance. Change in balance will be calculated as the Week 6 score minus the baseline score.
Baseline (Day 0) and Week 6
Change in Mobility as Assessed by the Amputee Mobility Predictor With Prosthesis
Tijdsspanne: Baseline (Day 0) and Week 6
Mobility will be assessed using the Amputee Mobility Predictor with Prosthesis (AMPPro), which evaluates functional mobility in lower-limb prosthesis users through 21 mobility tasks. The total score ranges from 0 to 47, with higher scores indicating better functional mobility. Change in mobility will be calculated as the Week 6 score minus the baseline score.
Baseline (Day 0) and Week 6

Secundaire uitkomstmaten

Uitkomstmaat
Maatregel Beschrijving
Tijdsspanne
Change in Depression, Anxiety, and Stress Symptoms as Assessed by the Depression Anxiety Stress Scales-21
Tijdsspanne: Baseline (Day 0) and Week 6
Mental health symptoms will be assessed using the Depression Anxiety Stress Scales-21 (DASS-21), a 21-item self-report instrument comprising three subscales: depression, anxiety, and stress, with 7 items in each subscale. Each item is scored from 0 to 3. The item scores for each subscale are summed and multiplied by 2, resulting in a score range of 0 to 42 for each subscale. Higher scores indicate greater severity of depression, anxiety, or stress symptoms. Change in each subscale score will be calculated as the Week 6 score minus the baseline score.
