Background:
In people with multiple sclerosis (pwMS), no formula exists to predict long walking capacity.
Objective:
To examine the accuracy of the timed 25-foot walk (T25FW) to predict long walking in pwMS with various degrees of walking dysfunction.
Methods:
A linear regression was made between the T25FW and the 6-minute walk test (6MWT) using data from 498 pwMS.
Results:
Prediction showed an excellent agreement between actual and predicted 6MWT distances, with an acceptable error of 10%, which increased as walking dysfunction increased.
Conclusions:
The T25WT provided acceptable prediction of the 6MWT in pwMS, although less accurate at higher degrees of dysfunction.
