This is a double-blinded randomized placebo controlled trial that tests the effect of ES on sensory (digital) nerve recovery in the human hand. Patients will be recruited in the hand trauma (Plastic Surgery) clinics across Edmonton. Once consented for the research study, the subject will undergo a battery of tests (Semmes-Weinstein Monofilament Test, 2-point discrimination, quantitative sensory testing for cold, warm and heat pain thresholds, as well as the Disability of the Arm, Shoulder and Hand [DASH] questionnaire) preoperatively to determine their baseline deficit prior to surgery.
