Fig. 1. — Comparison of the changes in MWS and 6MWD in the low-balance and high-balance groups.

We sub-divided the participants into two groups: low SPPB balance group (0–1 score) and high SPPB balance group (2–4 score) after intervention. 6MWD significantly improved in the high SPPB balance group than in the low SPPB-balance group (p<0.05). No significant improvement in MWS was found in either group. The Mann-Whitney U test was used to compare the amount of changes between the low-balance and high-balance groups. There were 7 patients in the low SPPB balance group, 1 patient in the HAL group, and 6 patients in the conventional group. On the other hand, there were 12 patients in the high SPPB balance group, 8 patients in the HAL group, and 4 patients in the conventional group.
