Baseline values did not differ between groups: MEP amplitudes: t-test: p = 0.597 (mental imagery group: mean: 1.493 mV ± 0.809 mV; controls: mean: 1.700 mV ± 1.117 mV); MEP integral: t-test: p = 0.816 (mental imagery group: mean: 0.0214 mV*s ± 0.0141 mV*s; controls: mean: 0.0193 mV*s ±0.0127 mV*s).

Mean and standard deviation of MEP amplitudes and integral before and after the intervention in both groups (MD = missing data).
