Background: In community-dwelling elderly individuals, slower gait speed is closely related to the ground reaction force. In the elderly with fall experience, stride length and gait speed, and other gait parameters are closely related to gastrocnemius activation. Objectives: To investigate whether medial gastrocnemius stiffness influences gait parameters in community-dwelling elderly people who experienced falls. Design: Cross sectional study. Methods: A total of 149 community-dwelling older adults were assigned to the faller and non-faller groups. Gait parameters (step length, stride length, step width, cadence, heel and toe ground reaction force, heel and toe contact time), and stiffness of the medial and lateral gastrocnemius and tibialis anterior were measured using shear wave elastography. Results: Elderly fallers had shorter step and stride length, lower cadence and toe ground reaction force and heel contact time, and lower medial gastrocnemius stiffness than non-fallers. In elderly fallers, medial gastrocnemius stiffness was significantly correlated with step and stride length, step width, toe ground reaction force, and heel contact time. Conclusions: Lower medial gastrocnemius stiffness in the elderly fallers decreases gait parameters, which can be a risk factor for falls. Therefore, medial gastrocnemius stiffness is a major factor that may associated gait parameters that can determine the risk of fall in community-dwelling elderly individuals.참고 자료
