Addition of isolated wrist extensor eccentric exercise to standard treatment for chronic lateral epicondylosis: a prospective randomized trial.

Background: Isokinetic eccentric training of the wrist extensors has recently been shown to be effective in treating chronic lateral epicondylosis. However, isokinetic dynamometry is not widely available or practical for daily exercise prescription. Therefore, the objective of this study was to assess the efficacy of a novel eccentric wrist extensor exercise added to standard treatment for chronic lateral epicondylosis.

A nonlinear constituent based viscoelastic model for articular cartilage and analysis of tissue remodeling due to altered glycosaminoglycan-collagen interactions.

A constituent based nonlinear viscoelastic (VE) model was modified from a previous study (Vena, et al., 2006, "A Constituent-Based Model for the Nonlinear Viscoelastic Behavior of Ligaments," J. Biomech.

The effect of scapular-retractor fatigue on external and internal rotation in patients with internal impingement.

Context: Scapular strengthening is thought to be an important component of the rehabilitation of patients with internal impingement.

Objective: To determine the effect of scapular-retractor-muscle fatigue on internal- and external-rotation-torque production in patients with internal impingement.

Design: Case control study.
