Background: Biomechanical factors have been associated with running-related injury, but associations are unclear. Dynamic postural stability may be a factor related to injury that has not been studied extensively.
Research Question: Does dynamic postural control differ in those with a history of running-related injury or those who go on to sustain a running-related injury?
Methods: Sixty-five (45 injured; 20 uninjured) and fifty-eight (13 injured; 45 uninjured) collegiate cross-country runners were available for our retrospective and prospective analyses.
Background: The study investigates the relationship between motor coordination errors and total errors using a human factors framework. We hypothesize motor coordination errors will correlate with total errors and provide validity evidence for error tolerance as a performance metric.
Methods: Residents' laparoscopic skills were evaluated during a simulated laparoscopic ventral hernia repair for motor coordination errors when grasping for intra-abdominal mesh or suture.
Background: The aim of this study was to evaluate working volume as a potential assessment metric for open surgical tasks.
Methods: Surgical attendings (n = 6), residents (n = 4), and medical students (n = 5) performed a suturing task on simulated connective tissue (foam), artery (rubber balloon), and friable tissue (tissue paper). Using a motion tracking system, effective working volume was calculated for each hand.
The demand for competency-based assessments in surgical training is growing. Use of advanced engineering technology for clinical skills assessment allows for objective measures of hands-on performance. Clinical performance can be assessed in several ways via quantification of an assessee's hand movements (motion tracking), direction of visual attention (eye tracking), levels of stress (physiologic marker measurements), and location and pressure of palpation (force measurements).

Our hypothesis was that participants would alter their technique based on tissue type with each subsequent stitch placed while suturing.
Materials And Methods: Surgical attendings (n = 6), residents (n = 4), and medical students (n = 5) performed three interrupted sutures on different simulated materials as follows: foam (dense connective tissue), rubber balloons (artery), and tissue paper (friable tissue).
Background: The aim of this study was to evaluate validity evidence using idle time as a performance measure in open surgical skills assessment.
Methods: This pilot study tested psychomotor planning skills of surgical attendings (n = 6), residents (n = 4) and medical students (n = 5) during suturing tasks of varying difficulty. Performance data were collected with a motion tracking system.
