Needle and surface electromyography of TA and plantar flexors

Electrophysiological Parameter Control (n = 12) DPN (n = 12) %Difference
TA CMAP, mV 6.8 ± 0.9 5.0 ± 1.7* −26.5%
TA mSMUP, μV 77.0 ± 20.0 116.0 ± 61.0* +50.6%
TA MUNE, # 99.0 ± 19.0 54.0 ± 25.0* −45.5%
Mean TA firing rate at 25% MVC, Hz 12.2 ± 1.7 10.1 ± 1.2* −17.2%
MVC % antagonist (plantar flexor) coactivation 2.7 ± 0.9 4.4 ± 2.4

Values are means ± SD. mSMUP, mean surface detected motor unit potential; MUNE, motor unit number estimation.
