About

Due to the age associated sarcopenia and reduced cardiovascular fitness, frail older adults experience significant decrease in physical function which comprises of mobility, endurance, muscle strength and balance control. The impaired physical function results in poor quality of life and reduced community participation, leading to increased frailty and long-term disability. Further, compared to cognitively intact frail older adults, cognitively impaired frail older adults experience greater deterioration of such physical function, specifically during dual-task performances (i.e., simultaneous performance of cognitive and motor task). This deterioration occurs due to increased cognitive-motor interference as a result of dual-tasking and is known to increase exhaustion among frail older adults. Previous studies have used multicomponent training and have shown to improve physical function and maintain cardiovascular functioning. However, the capacity of such interventions to improve cognitive function along with physical function is not known or unclear. Further, the concurrent comorbidities that occur along with psychosocial issues such as depression present as barriers and lead to reduced compliance to therapy leaving only a few of them to benefit from it. Alternate forms of therapy such as exergaming with explicit cognitive training has shown promising effects in improving motor and motor function in disabled populations. These studies use a cost-effective, off the shelf device such as Nintendo Wii or Microsoft Kinect to deliver the training which is easily available and clinically translatable. Further, such training has demonstrated increase in brain connectivity enhancing cognitive functions associated with balance control. However, there is limited literature examining the effect of exergaming in older frail population and the efficacy of such training is unknown. Therefore, this study proposes a randomized controlled trial to examine the feasibility of CogXergaming program with an aim to improve locomotor-balance control, cognition, muscular system and cardiovascular fitness.

Full description

The population of adults aged 60 years and older has been growing with around half of the people older than 85 years estimated to be frail. Age-related changes in multiple systems affecting balance, mobility, muscle strength, motor processing, cognition, nutrition, endurance and physical activity (PA) results in frailty. Studies on frail older adults have reported improvement in mobility and functional level following exercise interventions. Regular physical activity in this population has helped improve cardiovascular conditioning and quality of life, thus allowing these frail older adults a chance at independent living in the community. In addition to physical comorbidities, the presence of psychosocial issues such as depression may act as a barrier to community participation. Several PA interventions have demonstrated limited long-term effect and sustainable behavioral change in this population. An evidence-based fall prevention program called Matter of Balance (MOB) was developed to reduce fall risk and improve physical function and maximize activity participation in older adults. Meanwhile, Exergaming, a task-specific interactive gaming, has been gaining attention as a novel therapeutic alternative that promotes motor recovery in healthy and disabled populations. Exergaming involves repetitive-task specific exercises with movement execution feedback and motivation provided in real time. Studies have shown Exergaming improved symmetrical weight shifting, multi-directional stepping, single-stance, rapid movement training and self-initiated postural weight shifts in the participants. This anticipatory postural control training helps significantly improve balance control and mobility. In addition to the physical function domains that underlie physical frailty, executive cognitive domain functions also predict late-life physiological impairments. Thus, we postulate that PA facilitated through Exergaming and accompanied by simultaneous cognitive training is a novel approach to counter and inhibit frailty associated with physical function and cognitive decline. Aim 1: To test the feasibility (compliance and effectiveness) of cognitive-motor exergaming (CogXergaming) in the frail older adults and to compare the improvements in behavioral biomarkers in this group across balance, muscle fitness, cardiovascular fitness and global cognition to the group receiving the Matter of Balance training. Hypothesis: Participants will respond well to CogXergaming training paradigm and demonstrate significant improvements in balance, muscular fitness, cardiovascular fitness and global cognition as compared to the Matter of Balance training group. Aim 2: To examine the effect of CogXergaming on physical activity levels and quality of life measures post-intervention. Hypothesis: The participants who received CogXergaming will demonstrate significant improvement in physical activity and quality of life post-training as compared to their own pre-training scores. Aim 3: To examine the effect of CogXergaming structural and functional connectivity within the cognitive-motor areas pre and post training to establish effect size. Hypothesis: Post-training, participants will demonstrate improved memory consolidation, attention, motor planning and execution compared to pre-training indicating improved functional connectivity within the cognitive-motor areas.

50 participants in 2 patient groups

CogXergaming
Experimental group
Description:
CogXergaming based cognitive-motor balance training will be delivered to group A using the commercially available Wii-Fit Nintendo and a mouse in conjunction with cognitive training. All participants will undergo 18 sessions of training in a tapering manner for six weeks with 60-90 minutes of training per session, i.e., 3 sessions each week till the 6th week. Each session will be divided into 3 sub-sessions, where each sub-session will consist of playing 4 to 6 games in conjunction with cognitive task. All the games will be performed using a Wii-Fit balance board in front of a TV screen.
Treatment:
Behavioral: CogXergaming
Matter of Balance Training
Experimental group
Description:
Participants in group B will undergo matter of balance training for 8 weeks (one session a week for 2 hours/day).
Treatment:
Behavioral: Matter of Balance Training
