Table 2.
Values of average estimates and estimates of variability for the unipedal gait parameters with the following statistics: sample size (N), mean and standard deviations (SD) with GAITRite®, mean and standard deviations (SD) with insoles and p-values of t-test with independent samples and Levene’s test between GAITRite® and the insoles.
| N | Mean GAITRite® Lower Limit [Mean] Upper Limit | Mean Insoles Lower Limit [Mean] Upper Limit | SD GAITRite® Lower Limit [Mean] Upper Limit | SD Insoles Lower Limit [Mean] Upper Limit |
