The Generalized Linear Mixed Model was used to analyze the effects of group, task, group* task.
The models were controlled by gender, age, height, weight, education level, score of Mini-Mental State Examination and Hamilton Depression Rating Scale, gait velocity.
All of the P-values were corrected using Benjamini–Hochberg multiple testing correction.
P < 0.05 were considered statistically significant and highlighted in bold.
CI, confidence intervals; β, beta; ref, reference; Group*Task: The interaction between group and task; ST, single task; GV, gait velocity; SL, stride length; TO, toe-off angle; HS, heel strike angle; CV, coefficient of variation; AI, asymmetry index.
