Stroke
survivors need assistance to overcome cognitive impairments. Working
memory (WM) and processing speed (PS) as two critical cognitive
functions are disrupted by stroke. The goal of this study was to
investigate the effect of RehaCom rehabilitation software on WM and PS
in participants with chronic ischemic stroke with hemiplegia (right/left
side). Participants were selected among stroke patients who were
referred to our special rehabilitation clinic. Fifty participants were
assigned to control (n = 25) and experimental (n = 25)
groups. The results of the experimental group were compared with the
control group before and after the treatment with RehaCom (ten 45-min
sessions across five weeks, two sessions per week). The results showed a
significant improvement in WM and PS in the experimental group in
comparison with the control group after a 5-week training with RehaCom.
In conclusion, our findings indicate that treatment with RehaCom
software improves WM and PS in chronic ischemic stroke participants with
hemiplegia. The exact mechanism of RehaCom is largely unknown and
further studies are needed, but its effects on the function of brain
regions involved in modulating cognitive functions such as the
prefrontal cortex, cingulate cortex, and parietal cortex may be
mechanisms of interest.
