3. Normative Data
The normative data charts provided in this manual can be used to develop rehabilitation
programs and discharge criteria for patients. The normative values are based on age and
gender; therefore, comparisons can be easily made.
NOTE: Clarification of Normative Data for the Gait Trainer: The normative data and goals
presented in the Biodex Gait Trainer are derived from the reference tables in Gait Analysis, An
Introduction, 2nd. Edition, Michael W. Whittle, 1997, pgs. 218 - 219.
The cycle time in Whittle’s research is measured in seconds, whereas the Gait Trainer uses
cycles/second. Therefore, data is presented as the inverse function of the cycle time:
Cycles per second = Cycles
-1
Whittle also presents normative data for stride length. The Gait Trainer uses step length. A
stride equals two steps; therefore, these tables represent stride length divided by two.
