This study aimed to investigate the lower limb musclesʼpostural dynamic response to handgrip holding and temporal instruction of floorʼs lateral movement during transient lateral floor transition in the elderly. The study included 11 healthy elderly male subjects with a mean age of 75.9±7.0 years. There were four conditions used in combination with handgrip holding and temporal instruction during transient lateral floor transition. Lower limb muscle activities before and after lateral floor transition were measured using an electromyogram. The results revealed that the maximum muscle activities dependent on the direction of disturbance were reduced in the temporal instruction condition. Furthermore, most of the leg musclesʼresting and maximal activities were decreased in the handgrip holding condition. In conclusion, it was revealed that standing balance could be maintained with a small amount of activity by handgrip holding and temporal instruction.
