Responsiveness and Validity of the Six-Minute Walk Test in Individuals With Traumatic Brain Injury
Physical Therapy, 03/06/2012Mossberg KA et al.
All measures correlated well with peak Vo2, establishing an acceptable level of criterion–related (concurrent) validity. The addition of heart rate and calculating the physiologic cost index was only slightly better at predicting peak Vo2, albeit nonsignificant, than a simple measure of total distance. The Six–Minute Walk Test provides a good estimate of peak aerobic capacity, and some measures are more responsive to change than others in patients recovering from traumatic brain injury (TBI).
