Measured Versus Predicted Walk Distance

DISTANCE	VALUE
Predicted distance (m)	275.8 (78.1)

Patient recordings from walk tests are used to train the model, with 10-fold cross-validation on the 30-second walking samples across all patients. Numbers in parentheses are standard deviations. Walk distance is measured by human observer as established standard, then compared to predicted distance using software computation from gait model, based on gait parameters.
