Design outcomes

Primary

MeasureTime frame
Comparison of changes in TUG (Timed Up and Go) test between the 5-day immediate HAL intervention group and the standard rehabilitation group, measured before and after implementation

Secondary

MeasureTime frame
Changes in the 30-second Chair Stand Test (CS-30), 10-meter Walk Test, and Short Physical Performance Battery (SPPB) Disease-specific evaluation scales (Modified Ashworth Scale, Scale for Assessment and Rating of Ataxia SARA, ALS Functional Rating Scale-Revised :ALSFRS-R, IBM Functional Rating Scale :IBM-FRS, GNE Myopathy Functional Activity Scale :GNEM-FAS) Patient-reported outcomes (Barthel Index, SF-36, walking ability, Visual Analog Scale (VAS) for difficulty in standing up) Safety evaluation (frequency and severity of adverse events, changes in vital signs, fatigue level, skin condition)
