“…Generally, gait ability is associated with lower extremity muscle force, while muscle mass and capacity for balance are needed for maintaining walking posture. Although a relationship between gait ability and balance function has been recognized 9) , the relationship between asymmetry in thigh muscle mass and extension/flexion muscle force has not been investigated. In the present study, the average percentage of the asymmetry of knee extension force was 10.4%, which was much greater than we expected, and it also showed a gradual increase with age.…”

“…Balance requires maintenance of a moving posture, since humans move in an unstable posture on two feet. In particular, decrease in ability to keep balance in elderly people will increase the risk of falls, which might result in various disorders and decrease of ADL including gait ability 9,16) . Therefore, ability to keep balance and gait ability are important physical abilities for elderly individuals.…”

“…Recently, several studies have shown that since both lower extremity muscle power and muscle mass strongly affect gait ability, the higher the gait capacity is, the greater the muscle power of the lower extremities should be 7,8) . Moreover, because balance function affects gait ability as well as muscle force 9) , gait ability is related to various physical abilities of the lower extremities.…”

The purpose of this study was to examine the influence of muscle mass/power of the lowerextremities, including asymmetry in knee extension force, on gait ability of Japanese community-dwelling elderly women. The study population comprised 30 women aged 65-89 years. The parameters examined were activities of daily living, physical performance, functional capacity, isometric muscle forces of knee extension and flexion measured by a dynamometer, and muscle mass measured by bioelectrical impedance analysis. Asymmetry in knee extension force was calculated from rate of difference between the right and the left knee extension forces. One leg balance with eyes open, 6-minute walking distance (6MD) and knee extension force decreased, while 10-m obstacle walking time and asymmetry in knee extension force increased with age. Gait ability including 6MD and 10-m obstacle walking time correlated with asymmetry in knee extension force, which also exhibited correlations with one leg balance with eyes open and knee extension force. The results of the present study indicate that on increase in asymmetry in knee extension force as well as a decrease in lower-extremity muscle force might accelerate the loss of gait ability, while the improvement of asymmetry in knee extension force might be beneficial to self-supporting life in elderly individuals.
