Discussion
In this study, group x time interactions indicated that participants who received the iExergame training program had significantly faster gait speeds and longer stride lengths during dual task walking, as well as reduced postural sway, compared to participants who received conventional intradialytic exercise training. Additionally, of the participants who received iExergame training, those who used assistive devices demonstrated more improvements in postural sway from the iExergame training than those who did not use assistive devices during a semi-tandem balance test. Few studies have included older adults in this population. In this study, significant differences over 4 weeks were seen in older adults, whereas several studies with longer interventions found no significant differences in gait or balance. This may suggest older adults with iExergame training demonstrate more improvements in a shorter period of time than adults who are not older or do not use iExergame training. However, despite randomization, participants who received the iExergame training program were significantly younger than participants who received the conventional intradialytic exercise training, which may have influenced findings. More research is needed to assess the influence of age on the benefits of iExergame training.Our previous study discussed participants’ self-reported perceived benefits of the iExergame training
