Suprascapular		1.7(84%↓)						3.3(76%↓)
Musculocutaneous	7.3(61%↓)	4.5(52%↓)		normal	3.6(62%↓)		normal	normal
Median	normal	normal		6.2(51%↓)	1.4(83%↓)		normal	normal
Ulnar	normal	normal		5.3(53%↓)	normal		normal	normal
Radial	normal	normal		5.2(55%↓)	normal		4.1(63%↓)	normal
Peroneal			NR			0.7(75%↓)
Tibial			3.0(79%↓)			normal
SNAP of nerves (μV)
Median	normal	NR		normal	NR		2.3(77%↓)	normal
Ulnar	normal	normal		2.8(60%↓)	normal		normal	normal
Radial	normal	normal		normal	NR		4.5(64%↓)	normal
Superficial peroneal			NR			NR
Sural			NR			normal

The amplitudes of CMAPs and SNAPs were compared with contralateral side

CMAP compound muscle action potential, SNAP sensory nerve action potential, μV microvolt, mV millivolt, NR no response
