Functional task kinematics of the thumb carpometacarpal joint.

Background: Abnormal biomechanical loading has been identified as an associated risk factor of osteoarthritis in the wrist and hand. Empirical data to date are insufficient to describe the role of altered biomechanics in thumb carpometacarpal (CMC) arthritis.

Questions/purposes: This is a pilot study to evaluate motion analysis of the upper extremity while performing functional tasks.

Active shape modeling of the hip in the prediction of incident hip fracture.

The objective of this study was to evaluate right proximal femur shape as a risk factor for incident hip fracture using active shape modeling (ASM). A nested case-control study of white women 65 years of age and older enrolled in the Study of Osteoporotic Fractures (SOF) was performed. Subjects (n = 168) were randomly selected from study participants who experienced hip fracture during the follow-up period (mean 8.

The use of a cognitive task analysis-based multimedia program to teach surgical decision making in flexor tendon repair.

Background: The aim of this study was to compare the surgical knowledge of residents before and after receiving a cognitive task analysis-based multimedia teaching module.

Methods: Ten plastic surgery residents were evaluated performing flexor tendon repair on 3 occasions. Traditional learning occurred between the first and second trial and served as the control.
