INTRODUCTION
Human gait is important for efficient and safe .
Gait analysis provides us with important information on the functional capacity of patients when making disability
assessments, and in intervention and treatment planning.
The gait speed substantially influences the gait pattern, and kinematic and kinetic characteristics.
When quantifying human gait by kinematic and kinetic characteristics, subjects are typically asked to walk at what
is called their normal gait speed.
In general, normal gait speeds have been shown to range from 1.05 to 1.43 m/s in healthy adults.
These subject-specific speeds of healthy subjects have been used to produce normative gait data that can be used as a reference when abnormal and/or pathological gait is assessed.
A possible limitation of this procedure is that slower gait speeds may be associated with decreased joint movements and joint kinetics.
At faster gait speeds, clinical evidence suggests that increased joint power is responsible for certain types of overuse injuries of the musculoskeletal system.
Thus, it is generally accepted that normal gait parameters follow a consistent pattern of change in response to changes in gait speed.
