Gait characteristics and their correlation with falls in elderly lung cancer patients with frailty syndrome under dual tasks
Objective To explore the gait characteristics of elderly lung cancer patients with frailty syndrome under dual tasks and their correlation with falls.Methods A total of 98 elderly lung cancer patients admitted to the eight wards of the Third People's Hospital of Jiujiang from January to December 2021 were selected as the research subjects.The simple frailty scale and the elderly fall risk assessment scale were used to evaluate and implement gait measurement.Investigate the cur-rent status of frailty in elderly lung cancer patients,compare the differences in gait parameters of elderly lung cancer pa-tients with different fall risks and frailty states during dual task walking,and analyze the correlation between gait parame-ters and fall risk scores under dual task walking.Results Among the 98 elderly lung cancer patients,36 cases(36.73％)ex-perienced weakness and 62 cases(63.27％)had no weakness.The walking speed,stride length,and stride frequency of frail individuals during dual task walking were lower than those of non frail individuals,and the stride time was longer than that of non frail individuals,with statistical differences(P＜0.05).The fall risk score of 98 elderly lung cancer patients was(12.65±2.16)points,of which 44 cases were at low risk of falls(44.90％)and 54 cases were at high risk of falls(55.10％).The walking speed,stride length,and stride frequency of individuals with high risk of falls during dual task walking were lower than those with low risk of falls,and the stride time was longer than those with low risk of falls,with statistical differ-ences(P＜0.05).The fall risk score of elderly lung cancer patients was negatively correlated with walking speed and stride length under dual tasks(P＜0.05),but not with stride frequency and stride time(P＞0.05).Conclusion Elderly lung cancer patients are more prone to gait abnormalities during dual task walking,which are manifested as slower gait speed,reduced stride length,and increased variability in stride time.Moreover,gait performance deteriorates more significantly in frail in-dividuals and those at high risk of falls.
