Spatial and temporal gait characteristics in pre-frail community-dwelling older adults.

Aim: A number of studies have explored possible relationships, behavior, and meanings of spatial and temporal gait variables in frail and pre-frail older adults, particularly the gait speed variable. However, it is necessary to know the relationship of other spatial and temporal gait variables of pre-frail older adults. Thus, the objective of the present study was to evaluate and compare gait standards between pre-frail and non-frail older people.

Methods: A total of 69 older adults aged 60 year and older, divided into two groups, non-frail (n = 42) and pre-frail (n = 27), were evaluated. Gait parameters were analyzed using the GAITRite® Platinum 26' Portable Walkway System.

Results: Pre-frail older people had smaller step lengths (P = 0.041), larger base of support (P = 0.040), lower speed (P = 0.019), lower single support percentage (P = 0.033) and higher double support percentage (P = 0.036), compared with non-frail older people. A history of falls was correlated to lower gait speed and step length in pre-frail older adults.

Conclusions: Identifying pre-frail older people could have significant clinical consequences, as frailty is a dynamic process, and such individuals can therefore progress into a state of frailty or revert to a non-frail state. Therefore, the identification of gait variables in pre-frail older people can be an important tool to recognize gait deficits and to initiate the appropriate treatment.
