简要总结
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.
详细描述
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.

研究组 & 干预措施
Dual-task and Perturbation Based Training
- Participants in the experimental group received combined perturbation and dual task training
- The intervention was conducted for 3 days a week for 6 consecutive weeks
- Each treatment session lasted approximately 40 minutes including 5 minute of warmup and 2 minutes of rest between 2 segments
- Primary training modality was treadmill
- Initial walking speed was determined individually for each participant by using 10MWT
- Perturbations were applied manually during treadmill walking
- The intensity of treadmill was progressively increased across sessions by change in directions of perturbations, unpredictability, walking speed and reducing hand support when safe
- Dual-task training is added after 3 session and will be performed concurrently with perturbation training.
- Cognitive tasks include counting backwards, naming animals, subtracting 3 from 100.
- The complexity of the task will progressively increased
- Safety should be ensured by using the harness
干预措施: Perturbation + Dual-Task Training (Procedure)
Perturbation Based Training
- Participants in control group received Perturbation Baesd Training Alone
- The intervention was conducted for 3 days a week for 6 consecutive weeks
- Each treatment session lasted 40 minutes including 5 minute of warm up and 2 minute of rest between segments
- Primary training modality was treadmill
- Initial walking speed was determined individually for each participant by using 10MWT
- Perturbations were appllied manually during treadmill walking
- The intensity of treadmill was progressively increased across sessions by chanfe in directions of perturbations, unpredictability, walking speed and reducing hand support when safe
- Safety should be ensured by using the harness, keeping emergency stop at reach, and use of handrails when necessary
