Figure 6.
Effect of motor practice on SMO. SICI (±SE) is expressed as percentage inhibition relative to unconditioned control values. A–C show data obtained in APB, FDI, and ADM, respectively. Each graph shows two sets of data, for days 0 and 5. On each day, the four columns display the amount of SICI measured without muscle vibration (novib), during vibration of APB (vibAPB), during vibration of FDI (vibFDI), and during vibration of ADM (vibADM). A decrease in SICI is shown as increased column size and an increase in SICI as reduced column size. On day 1, short-term vibration decreases SICI in the vibrated muscle and increases SICI in the nonvibrated muscles. On day 5, vibAPB causes a stronger decrease of SICI, especially in the APB and FDI. Statistical results (t test; p values) of direct comparisons of days 0 and 5 are given in the figure.
