Reactive balance adjustments to unexpected perturbations during human walking . The purpose of this investigation was to determine the effect of unexpected forward perturbations ( FP ) during gait on lower extremity joint mechanics and muscle Electromyographic ( EMG ) patterns in healthy adults . The muscles surrounding the hip were found to be most important in maintaining control of the trunk and preventing collapse in response to the FP . Distinct lower extremity joint moment and power patterns were observed in response to the FP but an overall positive moment of support ( M ( s ) ) was maintained . Therefore , reactive balance control was a synchronized effort of the lower extremity joints to prevent collapse during the FP .
