Table 3 Mixed Linear Model Regression results for the primary (Motor Activity Log-14 Item Version Amount of Use Subscale (MAL-14 AOU)) and secondary outcomes (MAL-14 Quality of Movement subscale (MAL-14 QOM), sensor data) for the subset of the study population (n = 23). Logarithmic transformation was applied to the predictor variables (AAU, AUR, PTA). Intervention group = 1, control group = 0, mild impairment = 1, moderate impairment = 2, severe impairment = 3. Bold numbers indicate a significant predictor
