The functional reach test (FRT) evaluates the limits of physical
stability and is used to measure dynamic balance and flexibility during
the performance of functional tasks (Duncan et al. 1990).
Subjects were instructed to stand with feet at shoulder width and to
lift arms parallel to shoulder height (shoulders were prevented from
bending forward or backward) with arms stretched out as far as possible.
Then, the distance of moving the knuckle’s end was measured.
Measurements were conducted in centimeters; a longer distance represented
better balance ability. Results represent the average of three
consecutive measurements
