MEP amplitude across TMS coil orientations

Group/Grip	MEP Amplitude, mV
Task	LM	PA	AP
Controls
Precision	4.7 ± 2.6	2.1 ± 1.5	1.9 ± 1.4
Power	4.4 ± 2.3	1.6 ± 1.3	1.3 ± 1.0
SCI
Precision	1.3 ± 1.2*	0.6 ± 0.3*	0.6 ± 0.4*
Power	1.3 ± 1.1*	0.5 ± 0.3*	0.6 ± 0.3*

Values are means ± SD. MEP, motor-evoked potential; TMS, transcranial magnetic stimulation; LM, latero-medial; PA, posterior-anterior; AP, anterior-posterior; SCI, spinal cord injury.

^*Significant difference between groups within each coil orientation.
