Figure 4From: Upper extremity rehabilitation of stroke: Facilitation of corticospinal excitability using virtual mirror paradigmFacilitation of MEPs during visual-feedback-controlled virtual mirror exercise in healthy subjects and stroke patients . The amplitude increment and latency decrement of MEPs in healthy subjects and stroke patients were significantly greater for the intermittent visual feedback program (mode 2) than for the continuous visual feedback program(mode 1) (independent two sample t-test; **P < 0.01).Back to article page
