Functional outcomes
ANTERIOR
The 2-min Walk Test (2MWT) was used to assess participants’ aerobic capacity. This test recorded the distance covered in 2 min (The Five Times Sit to Stand Test (5xSTS) was used to record the required time (s) to rise from a chair five times. It assessed functional lower-limb strength, and it also has shown excellent reliability (ICC = 0.89) [An inertial sensor embedded in the Android device FallSkipPhase 1. Standing still with arms alongside the body for 30 s.Phase 2. Walking straight ahead as fast and as safely as possible towards a chair 3 m away at the sound of an acoustic signal.Phase 3. Turning around and sitting down in a chair.Phase 4. Standing up from the chair.Phase 5. Walking back as fast and as safely as possible to the starting point.Three variables were calculated for the static postural control phase: i. Medial–lateral (ML) displacement of the centre of mass (in mm); ii. Anterior–posterior (AP) displacement of the centre of mass (in mm); and iii. Displacement area of the centre of mass (in mmLikewise, turning around and sitting down and standing up from the chair were also monitored and three variables were calculated: i. Standing-to-sitting time (in s); ii. Standing-up power (in W); and iii. Sitting-to-standing time (in s). Finally, two time-related variables were calculated: i. Total time (s); ii. Reaction time from a sound stimulus (s) [
