Abstract

Purpose: This study aimed to determine the effects of a 2-yr-long maintenance training (MT) exergaming and detraining (DT) on clinical–motor symptoms in subacute ischemic patients with stroke (PwST). The hypothesis was that MT motor rehabilitation program would further increase the effects of the initial rehabilitation. Methods: After high-intensity and high-frequency exergaming twice or once a day, 5 times per week for 5 wk (EX2: 50 sessions; EX1: 25 sessions, results reported previously), 558 PwST were randomized to EX2-MT, EX2-DT, EX1-MT, and EX1-DT. MT exergaming consisted of once a day, 3 times per week for 2 yr, and DT did not train. Outcomes were measured at 6, 12, 18, and 24 months. The data were analyzed using longitudinal linear mixed-effects models and general linear hypotheses testing. Results: Modified Rankin Score (primary outcome), body mass, Mini-Mental State Examination score, Beck Depression Inventory, measures of quality of life, Berg Balance Scale, 6-min walk test, and four measures of center of pressure path tended to retain the initial rehabilitation-induced gains in the MT patients in selected outcomes (especially walking capacity). The scores tended to mildly worsen after DT, partially supporting the hypothesis. Conclusions: MT successfully maintained, but only in selected variables did it further increase the initial exergaming rehabilitation-induced robust improvements. DT modestly reduced the initial exergaming rehabilitation-induced improvements. MT programs might be needed after initial stroke rehabilitation to reduce subsequent losses of quality of life and further improve clinical–motor symptoms.
