New endoscopists require a large volume of expert-proctored colonoscopies to attain minimal competency. Developing multi-fingered, synchronized control of a colonoscope requires significant time and exposure to the device. Current training methods inhibit this development by relying on tool hand-off for expert demonstrations. …

Introduction: Visual demonstration and verbal direction are instructional formats for training endoscopists. These methods are inefficient in developing trainees' muscle memory or technical competence--as skill acquisition comes through sensory exposure and hands-on practice. Accurate assessment of technical skill is a first step …
