Description

WA PhotoThe WA quantifies characteristics of gait as the patient walks across the length of the forceplate. The test characterizes steady state gait by having the patient begin well behind and continuing beyond the forceplate. Because of the length of the forceplate, the test may not be appropriate for highly fit individuals whose stride lengths are greater than five feet (152 cm). Measured parameters are average step width, average step length, speed and step length symmetry.

WA Comprehensive Report

  1. The COG trace for each trial is shown on the left side of the report.
  2. Step Width is the lateral distance in centimeters between the left and right feet on successive steps.
  3. Step Length is the longitudinal distance in centimeters between successive heel strikes on successive steps.
  4. The Speed is the velocity in centimeters per second of the forward progression.
  5. The Step Length Symmetry is the comparison of right and left step length, expressed as a percentage of the total stride length (left and right length).

Functional Implications

Gait is a critical element of mobility, which can be affected by a large number of impairments. The WA is therefore a sensitive test of overall functional capabilities, but highly non-specific. Factors influencing gait include cognitive and motor planning abilities, overall conditioning, balance, movement control, strength and range of motion.

Gait velocity is a useful measure of overall gait ability; and stride width is an overall measure of balance ability. Together, gait velocity and stride width can be utilized as an objective predictor of rehabilitation potential.
