Mean and standard deviation of the Semmes Weinstein Monofilament Test (SWMT) pressure thresholds assessed at baseline, 3 months, and 6 months after digital nerve repair and ES therapy delivered using Investigational PeriPulseTM. A SWMT pressure thresholds at 3 and 6 months were significantly lower than scores at baseline (p< 0.05 and p < 0.01, respectively). Statistically significant improvement was also shown between 3 and 6 month scores (p< 0.05). Note, these values are the standard filament values which represent the logarithm of ten times the force in milligrams of each filament. B Pressure threshold scores represented in grams of force. Baseline thresholds represent patients that were feeling deep pressure only or were insensate. Dashed line represents the force an uninjured person would feel on the lateral or medial portion of the distal aspect of the digit (< 0.4 g). A historical comparator from the literature, Arnaout et. al shown in dotted line at mean value 68 g. This includes patients in the Arnaout study with both sharp or jagged lacerations
