Combined Effects of Dual-task and Perturbation Based Training on Balance and Cognition in Stroke Patients

Summary

This study aims to evaluate the Combined Effects of Dual-task and Perturbation Baesd Training on Balance and Cognition in Stroke Patients. Stroke is an acute cerebrovascular disorder that can impair cognitive, motor, and balanace abilites. Stroke is the second largest cause of death and disability globally. According tp studies, people who have had a stroke are more likely to fall than others who are same age and gender. PBBT is known as artificially induced balance training technique that can mimics the loss of balance that can occur naturally in freal life. Reduction in falls has been reported broadly by the use of perturbation based balance training. Current study will be and RCT on 33 participants based on the inclusion critieria. Participants will be randomly and equally divided into two groups; group B receiving Perturbation Based Training Alone and Group A receiving Dual-task and Perturbation Based Balance Training. The treatment will be given for 40 minutes, 3 days a week for 6 consecutive weeks. The assessment will be conducted at baseline, for cognition by Montreal Cognitive Assessment Scale (MoCA), for initial treadmill speed 10 Meter Walk Test (10MWT), for balance by Berg Balance Scale (BBS), and for fall riak by Fall Efficacy Scale (FES). Final assessment will be conducted after 6 weeks.

Interventions

PROCEDURE

Perturbation-Based Training

The control group will participate in a structured six-week intervention program consisting exclusively of the Perturbation Based Balance Training. Participants will attend three supervised sessions per week, ensuring consistent oversight and proper technique throughout the program. Each session will began with a warm-up period, followed by two 8-minute segments of perturbation-based treadmill training, with participants allowed a rest period of 60 second to 2 minute between repetitions to prevent fatigue and maintain the quality of each movement. The frequency is maintained consistently, however, perturbations dosage was progressively increased across all six weeks to provide a standardized exposure, allowing for accurate comparison with other intervention groups. Over the entire six-week period, participants will complete a total of 18 supervised sessions, each with three repetitions, summing up to 108 bouts across the intervention.

PROCEDURE

Perturbation + Dual-Task Training

The intervention program spans six weeks and involves both supervised Perturbation sessions and Dual-Task training exercises. Participants will attend three supervised Perturbation based training per week, with each session consisting of two 8-minute segments of the training. In addition, participants will perform Dual-Task training and perturbations on treadmill, with each cycle consisting of two segments. This combination of supervised practice will be increased progressively throughout all six weeks. Across the entire program, participants will complete a total of 18 supervised perturbation based balance training and 18 Dual-task training sessions.
