Summary of Repeated Assessments

				Value at:
Test	N=	# of tests per subject	Months between repeat tests	Baseline	Last Follow-Up	Last Follow- Up vs. Baseline

Nerve Ultrasound: Average Nerve Size Index	23	3 (2–4)	7 (1–32)	172% (82–461)	137% (87–388)	P=0.03

Grip Strength	19	3 (2–4)	7 (1–32)	271N (4 – 632)	400N (107 – 636)	P=0.02

includes 11 subjects with baseline study performed prior to initial nerve ultrasound.

^**

Demyelinating features of motor nerve conduction studies include: conduction block, very slowed conduction velocity, very prolonged distal latency, or increased temporal dispersion.²¹ One subject (#23) with absent electrodiagnostic reponses was excluded.

All values median (range) unless otherwise specified.
