SSS=Symptom severity scale; FSS=Functional status scale; SNCV
(m/s)=Sensory nerve conduction velocity; DML (ms)=Distal motor latency;
CSA (mm2)=Cross-sectional area; SE=Standard error.
aWilcoxon Signed Ranks Test (comparison with baseline,
intragroup), bMann-Whitney U Test (mean, intergroup).
The 2-way ANOVA was used to test the group by time interaction, the
p-value was 0.661, 0.749, 0.709, 0.049 and 0.537 for SSS, FSS, SNCV, DML
and CSA, respectively.
