Objective To investigate the relationship between dual-task-related gait features and different frailty states among community-elderly. Methods A total of 191 elderly patients with different frailty states were selected conveniently. According to their FRAIL scores, the elderly were divided into a frailty group (16 cases), a pre-frailty group (111 cases) and a non-frailty group (64 cases).Basic data were collected by a general information questionnaire, and from the Mini-mental State Examination;a portable gait analyzer was used to record the gait parameters of the elderly while they were asked to walk a straight line of 17 m and simultaneously perform another task.Results There were significant differences in walking speeds, step frequency, step length and step time among the elderly with different frailty states (P＜0.01 for all).The walking speed and step length of the pre-frailty group were significantly lower than those of the non-frailty group (P＜0.05 for all); the walking speed, step frequency, step length and step time of the frailty group were significantly lower than the other 2 groups (P＜0.05 for all).Conclusion The dual task walking test shows that the gait performance of the community elderly is disordering, and frailty aggravates further deterioration of gait.
