Change in Reciprocal Inhibition of the Forearm with Motor Imagery among Patients with Chronic Stroke

Figure 1

Comparison between reciprocal inhibition at rest and reciprocal inhibition during motor imagery. Significant changes were found in reciprocal inhibition (RI) during motor imagery (MI) at both an interstimulus interval (ISI) of 0 ms and 20 ms compared with RI at rest. Data are the mean ± standard deviation.

(a) ISI 0 ms

(b) ISI 20 ms
