Primary

MeasureTime frame
Measured at baseline and 3 months: 1. Cognitive ability is measured using the Beijing version of the Montreal Cognitive Assessment (MoCA) 2. The presence and severity of diabetic peripheral sensorimotor polyneuropathy is measured using The Toronto Clinical Scoring System (TCSS) 3. Depression and anxiety is measured using Hospital Anxiety and Depression Scale (HADS) 4. Movements, the individual’s risk of falls and other adverse consequences is measured using the Timed Up and Go (TUG) test and Gait speed
