Brief 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.
Detailed description
Stroke is a multifaceted disease that can be caused by a variety of risk factors, disease processes and causes. Stroke results in the change of cognitive function, which effects resulting in minor impairment to the development of post-stroke dementia. The cognitive deficiencies in a stroke survivors have significant influence on their daily productivity. In addition, falls are a prevalent and potentially fatal issue for as many as 47% of all stroke patients admitted to the hospital.Some studies suggest that Dual-task training when paired with mechanical action of treadmill could maximize the constraint on the cognitive control processes for gait.
Interventions
PROCEDUREPerturbation-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.
PROCEDUREPerturbation + 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.

Secondary
| Measure | Time frame | Description |
|---|---|---|
| Fall Risk | 6 Weeks | Fall Efficacy Scale (FES), Total score=10-100 (higher score = greater fear of falling |
