Table 1a: CTS severity based on electromyography data for median motor distal latency (MDL) and median segmental sensory latency (SDL).

Median Motor Distal
Latency (MDL)		 N Mean (SD) Minimum Maximum
Mild (3.8-4.5ms) 16 4.14 (0.24) 3.80 4.50
Moderate (4.6-6.0ms) 23 5.26 (0.40) 4.60 6.00
Severe (>6.0ms) 6 8.03 (2.25) 6.10 11.70
Median Segmental Sensory Latency (SDL) N Mean (SD) Minimum Maximum
Mild (3.0-3.5ms) 4 3.26 (0.25) 3.00 3.50
Moderate (3.6-4.5ms) 2 4.05 (0.35) 3.80 4.30
Severe (>4.5ms) n/a n/a n/a n/a

SD = Standard Deviation.n/a = data not available (no severe cases were found with SDL).
