MEP latency differences across TMS coil orientations with amplitude matched

	Latency Differences, ms
Group/Grip	PA-LM	AP-LM
Controls
Precision	1.57 ± 0.35	2.98 ± 0.84
Power	1.56 ± 0.44	3.71 ± 0.68*
SCI
Precision	0.97 ± 0.42	1.83 ± 1.11
Power	1.06 ± 0.32	2.33 ± 1.00*

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

^*Significant difference between tasks within each group and coil orientation.
