Computerized assessment of gait is commonly used in both research and clinical
settings to quantify gait mechanics and detect change in performance. Minimal
Detectable Change values have only recently been reported, are only available for
patient populations, and in many cases exceed 10 degrees . Twenty nine healthy
individuals underwent two biomechanical gait assessments separated by 5.6 (SD
2.2) days, with two raters for each session. All subjects walked at a self
selected pace and three controlled velocities. ICC, SEM and MDC for kinematic and
kinetic measures were calculated for interrater-intrasession,
intrarater-intersession and interrater-intersession. ICC values were in the good
to excellent range (r>0.75) for all kinematic and kinetic variables and all
comparisons. MDC values were lower than previously published data for all similar
comparisons. The results of the current study suggest that reliability is good to
excellent across a range of controlled walking velocities and the introduction of
a second rater does not appreciably impact ICC or MDC values. In young healthy
adults changes in gait kinematics of greater than approximately 5 degrees can be
identified when comparing between sessions.
