Effects of kinesthetic illusion induced by visual stimulation (KINVIS) therapy on patients with stroke in the subacute phase: a visual analysis based on paralysis severity

We explored the effect of kinesthetic illusion induced by visual stimulation (KINVIS) therapy on motor function in patients with stroke during the subacute phase based on paralysis severity. The study was performed using an ABAB design (A1, B1, A2, B2; for 10 days each). KINVIS therapy was additionally administered in periods B1 and B2. Ten patients with stroke were classified according to severity. The improvement in upper limb motor function was higher after B1 and B2 than after A1 and A2 in the moderate group. The effect of KINVIS therapy increases the degree of improvement in motor function, especially in the moderate group.
