[ 2 ] - Predictors of Upper-Extremity Physical Function in Older Adults
Background: Little is known about the influence of habitual participation in physical exercise and diet on upper-extremity physical function in older adults. To assess the relationship of general physical exercise and diet to upper-extremity physical function and pain intensity in older adults.
