The Effect of a Novel Dual-Task Exercise Program for Balance, Mobility and Cognition in Community Dwelling Older Adults
The development of a Treadmill Rehabilitation Platform (TRP) for task-orientated rehabilitation that provides an adapted, blended approach among older adults with balance, mobility, and cognitive impairments.
Examine the feasibility and benefits of a novel dual-task intervention to address mobility and cognitive decline with age using engaging interactive video games during treadmill walking and recumbent cycling.This will include evaluation of the effects of two interventions, one using treadmill walking and the second a recumbent cycle ergometer on
- Core balance
- Cardiac fitness, exercise endurance
- Gaze control
- Gait performance measure (walking stability and spatial-temporal gait parameters)
- Specific executive cognitive function (processing speed, cognitive inhibition, working memory)
- Dual task function during treadmill walking
- Dual-task exercise program will improve core balance and walking function to a greater extent in the Treadmill walking group compared to recumbent cycle group.
- Executive function will improve equally in both the treadmill walking and recumbent cycle group.
- Dual task exercise programs will have significant effect on gaze stability and cardiac fitness equally for both the treadmill and recumbent cycling groups.

- Dual task function during walking [ Time Frame: Pre and post intervention of 10 weeks ]Walking on at treadmill at a speed of 0.9 m/s while performing a cognitive game task simultaneously i.e the participants move a paddle (game sprite to catch bright circle objects(targets)moving vertically top to bottom, avoiding other shape(or colors) game objects (dis-tractors). This test game provides an objective quantification of cognitive functions like (i) Game success rate (percentage of target caught), (ii) average motor response time (time from appearance of the target to start of the paddle movement), (iii) average movement execution time (iv) movement efficiency .
- Executive function [ Time Frame: Pre and post intervention of 10 weeks ]Neuropsychological tests:Trail making test (A and B), Verbal Fluency, Visual Search and the dimensional change card sort test
- Core Balance [ Time Frame: Pre and post intervention of 10 weeks ]I t will be measured by performing a) Clinical Test of Sensory Integration of Balance and b) Five - Time Sit-to-Stand Test
- Spatial - temporal gait variables [ Time Frame: Pre and post intervention of 10 weeks ]It will be measured by asking the participants to walk on a treadmill for 2 minutes which is instrumented with a pressure mat at a speed of 0.9 m/s. Average and coefficient of variation will be obtained for the following parameters: swing time, step time, step length and step width.
- Cardiac fitness [ Time Frame: Pre and post Intervention of 10 weeks ]Cycle ergometer Submaximal Test will be performed measuring the heart rate, blood pressure, revolution per minute and rate of perceived exertion at an interval of 5 minutes.
- 6- Minute walk test [ Time Frame: Pre and post intervention of 10 weks ]
- CHAMPS Questionnaire [ Time Frame: Post intervention of 10 weeks ]

Dual Task Treadmill Walking Exercise Program
Behavioral: Dual task treadmill walking exercise program
Participants will receive 5 minute warm up and cool down session followed by a 30 minute dual task program which includes treadmill walking while playing brain fitness or cognitive games. Rest periods will be provides to the participants. Treadmill speed will be set so as to not exceed 60% of maximum heart rate. Heart rate and perceived excretion( per the Borg 1-10) will be measured at 5 minutes of interval.
Active Comparator: Control group
Dual task recumbent cycling exercise program
Behavioral: Dual task recumbent cycling exercise program
Participants will receive a 5 minute warm up and cool down session followed by a 30 minute dual task exercise program which includes recumbent cycling while playing brain fitness or cognitive games. Rest periods will be provides to the participants. Recumbent cycling speed will be set so as to achieve 60% of maximum heart rate. Heart rate and perceived excretion( per the Borg 1-10) will be measured at 5 minutes of interval.
