*2.6. Statistical Analysis*

The distributions of individual parameters such as body weight and height are near normal since they were tested using the Shapiro–Wilk test (*p* > 0.05) [38]. To obtain more accurate descriptions, the coefficient, initial phase, and walking cadence are averaged across the two selected gait cycles for all the subjects. Moreover, the average value and standard deviation of the model errors from all the subjects were calculated to evaluate the dynamic model. All calculations and statistical analyses in this study were carried out using MATLAB (9.6.0.1072779 (R2019a)).
