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

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.

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.
