ABSTRACT
BACKGROUND:
The wireless gait assessment tool (Wi-GAT) measures have been shown to have good to excellent concurrent validity with preferred walking speeds, however, the validity of the Wi-GAT measures at slow and fast walking speeds is unknown.OBJECTIVE:
To establish validity of the Wi-GAT spatio-temporal gait measures at slow, fast, and preferred walking speeds.METHODS:
Twenty two healthy adult volunteers, with a mean age of 25.7 (± 5.3) participated in this study. The spatio-temporal gait variables of each participant were concurrently recorded using the GAITrite and the Wi-GAT system, while the participants performed 3 trials for each walking speed in a randomized order. Intraclass correlation analyses were performed to establish the agreement between the measures recorded by the GAITrite and Wi-GAT systems.RESULTS:
Walking speed measured both by the Wi-GAT and the GAITrite systems showed excellent agreement for preferred (ICC = 0.979 p< 0.001), slow (ICC = 0.989 p< 0.001) and fast (ICC = 0.967 p< 0.001) walking speeds. Most gait parameters recorded at slow walking speed showed good (ICC > 0.70) to excellent (ICC > 0.85) agreement.CONCLUSIONS:
Gait parameters recorded by the Wi-GAT system showed fair to excellent validity for preferred and slow walking speeds.Palavras-chave
