Effects of Aquatic and Land-Based Treadmill Gait Training on Static Balance Ability in Patients with Post-stroke Hemiplegia
This study aimed to compare the chronological effects of an 8-week aquatic treadmill versus land-based treadmill gait training program on multi-dimensional static balance ability—specifically total sway, anteroposterior (AP) sway, and mediolateral (ML) sway—in patients with chronic post-stroke hemiplegia. Eighteen post-stroke hemiplegic patients were randomly assigned to either the aquatic treadmill walking exercise group (n=9) or the land-based treadmill walking exercise group (n=9). The aquatic treadmill gait training (ATGT) group performed an underwater treadmill walking program, while the land-based treadmill gait training (LBTG) group conducted a conventional treadmill walking program, with both groups exercising for 30 minutes per session, 3 times a week, over an 8-week period. Static balance ability was quantitatively evaluated using the Biodex Balance System SD by measuring the degrees of total sway, AP displacement, and ML displacement at three time points (pre-test, 4 weeks, and 8 weeks). Post hoc analysis revealed that both groups achieved significant enhancements in total sway, anteroposterior (AP) displacement, and mediolateral (ML) displacement at 8 weeks compared to the pre-test baseline (p<.05). In particular, the ATGT group demonstrated significantly greater reductions in total sway and AP displacement compared to the LBTG group at the 8-week mark (p<.05), while no significant inter-group difference was observed in ML displacement. These findings demonstrate that both interventions are beneficial for post-stroke balance rehabilitation, suggesting that aquatic treadmill gait training is an effective clinical intervention to enhance static balance ability, particularly regarding overall postural stability and anteroposterior control, in patients with post-stroke hemiplegia.
