Clinical relevance using timed walk tests and 'timed up and go' testing in persons with multiple sclerosis.

Background And Purpose: One must understand the potentials and limitations of all tests used to evaluate interventions. The aim of the present study was to clarify the reproducibility, smallest percentage difference needed to be able to detect a genuine change and correlation regarding the 10-m and 30-m timed walks (10TW 30TW) and the 'timed up and go' (TUG) test in people with moderate multiple sclerosis (MS).

Method: A repeated-measures design was used, with randomization into two groups and different time intervals used for testing.
