We investigated changes across the adult life span of the fingertip forces used to grip and lift objects and their possible causes. Grip force, relative safety margin (grip force exceeding the minimum to avoid slip, as a fraction of slip force), and skin slipperiness increased beginning at age 50 years. Skin slipperiness explained relative safety margin(More)
This experiment addressed the often-posed theory that age-related declines in manual dexterity result from diminished tactile function. We measured the time 'young' subjects (n=33; mean=45 years) and 'old' subjects (n=33; mean=74 years) needed to grip (thumb and index finger), lift, and transport a small metal sphere when vision was permitted and when(More)
UNLABELLED GOALS/PURPOSE: Despite concerns of legal liability, preoperative computer imaging has become a popular tool for the plastic surgeon. The ability to project possible surgical outcomes can facilitate communication between the patient and surgeon. It can be an effective tool in the education and training of residents. Unfortunately, these imaging(More)
BACKGROUND Significant information exchange occurs between a doctor and patient through nonverbal communication such as gestures, body position, and eye gaze. In addition, empathy is an important trust-building element in a physician: patient relationship. Previous work validates the use of virtual patients (VP) to teach and assess content items related to(More)
© 2002 Association médicale canadienne T keys to successful treatment of tracheal tears after endotracheal intubation are early recognition, control of airway, antibiotic therapy and surgical repair. Surgical approaches to the repair of iatrogenic membranous tracheal injuries depend on the extent and location of the tear. Tears of the upper two-thirds can(More)
BACKGROUND The independent plastic surgery match is an extremely competitive process that remains the most common training model for residents. The purpose of this study was to analyze the candidates and the overall process, both quantitative and qualitatively. METHODS Between 2006 and 2008, an anonymous 25-question online survey was sent to all(More)
