Motor, Sensory, Cognition, Older, Falls, Balance Ability, Randomized Controlled Trial, Task-oriented Approach
Conditions
Brief summary
Motor, sensory, and cognitive functions all contribute to balance maintenance, and age causes deterioration in these functions with associated declines in balance ability and accidental falls. Relatively speaking, the sensory and cognitive functions are invisible in designing falls-prevention programs. The relative proportions of training of motor, sensory, and cognitive functions, for the most efficient falls-prevention program is a practical and important issue but has not been studied yet by directly comparing their intervention effects. This three-year project aims to provide evidence base for relative proportions of motor, sensory, and cognitive training when designing falls-prevention programs. The crossover randomized controlled trial (RCT) will recruit 120 community-dwelling elderly adults from local community centers. There will two experimental groups- sensory and cognitive training, one control group- motor training, each for 60 minutes per session, 3 times a week, for 16 weeks. The three groups will be trained with task-oriented design of balance exercise but focusing on different aspects, i.e., training will begin in the ICF body function level (focusing on motor, sensory, or cognitive function) in the stance position and will end in the ICF activity level (balance or mobility activities focusing on motor, sensory, or cognitive function). The primary outcome measures are rates of falls and near-falls in the ICF participation level, and the secondary measures are balance/mobility performance and risk of falling in the ICF activity level. In Taiwan, a great amount of expense is paid to prevent falls in the community setting. Through better understanding of the comparative intervention effects between motor, sensory, and cognitive training, this project hope to be able to suggest the relative proportions of motor, sensory, and cognitive training in falls-prevention exercise design.
Interventions
BEHAVIORALfalls-prevention programs
Each group will receive 10-minute warm up, followed by 20-minute exercises in the ICF body function level, 20-minute exercises in the ICF activity level, and finally 10-minute cool down. The 10-minute war up include dynamic mobility exercises of the upper extremity and trunk (ribbons dancing on a chair) and of the lower extremity (marching in place). The 10-minute cool down include flexibility exercises of multiple muscles especially focusing on neck, hamstring, and calf muscles.
