The effect of visual perturbation upon femoral acceleration during the single and bilateral squat.

Objectives: Record femoral accelerations using a smartphone accelerometer attached to the distal thigh during single-legged (SLS) and bilateral squats, and each squat condition occurred under two visual conditions: 1) normal vision and 2) visual perturbation with stroboscopic glasses.

Design: Repeated-measures cross-over with counter-balanced order for four total conditions.

Setting: Laboratory.
