Table 1 Overview of spatial and temporal gait parameters during preferred and fast walking speeds for 21 subjects. Values represent means over the trial (standard deviation). Left and Right sides for unilateral parameters were treated separately.

From: Test-retest reliability of temporal and spatial gait characteristics measured with an instrumented walkway system (GAITRite®)
