Research electronic data capture (REDCap) is a novel workflow methodology and software solution designed for rapid development and deployment of electronic data capture tools to support clinical and translational research. We present: (1) a brief description of the REDCap metadata-driven software toolset; (2) detail concerning the capture and use of(More)
The purpose of this study is to describe interstitial fluid flow in axisymmetric soft connective tissue (ligaments or tendons) when they are loaded in tension. Soft hydrated tissue was modelled as a porous medium (using Darcy’s Law), and the finite element method was used to solve the resulting equations governing fluid flow. A commercially available(More)
OBJECTIVES To characterize the perceptual assessment of vocal quality in subglottic stenosis (SGS) patients and to identify risk factors for dysphonia. STUDY DESIGN AND SETTING Retrospective review, academic center. METHODS Perceptual voice assessment using GRBAS scale (Grade, Roughness, Breathiness, Asthenia, Strain); patient characteristics determined(More)
We investigated the acute adaptation of the rat femur-medial collateral ligament-tibia (FMT) complex to 7 days of limb unweighting by means of a hind-limb suspension protocol. Male, young adult, Harlan Sprague-Dawley rats were randomly assigned to either control or suspended groups. Rats deprived of hind limb-to-ground contact forces had a 42% decrease in(More)
Seventeen 5 to 6-month-old Holstein heifer calves were divided into three groups and fed either a control ration alone or a control ration with sufficient sodium fluoride added to furnish an additional 30 or 50 p.p.m. fluoride based on total dry matter intake. After 6 years of the feedings, mean (SEM) fluoride concentrations in the metacarpals were found to(More)
BACKGROUND/PURPOSE Quality improvement (QI) is critical to enhancing patient care. It is necessary to prioritize which QI initiatives are relevant to one's institution and practice, as implementation is resource-intensive. We have developed and implemented a streamlined process to identify QI opportunities in our practice. METHODS We designed a web-based(More)
OBJECTIVES To determine if menstrual status changed in amenorrheic college runners over a 2-year period and what effect this had on brachial artery flow-mediated dilation. PARTICIPANTS Eighteen athletes first studied in our laboratory 2 years prior were available for follow-up. Nine of the 10 original women with athletic amenorrhea (mean +/- SE, age 21.3(More)
The variety of techniques used to measure the cross-sectional area of soft connective tissues during mechanical testing lead to inconsistencies in elastic descriptions. This study compares the numerical differences between finite elasticity (Eularian and Lagrangian formulations) and infinitesimal elasticity when considering stress, strain and elastic(More)
To evaluate the effect of laser energy at nonablative levels on the mechanical properties of joint capsular tissues, we tested the femoropatellar joint capsules of 12 mature New Zealand White rabbits. Specimens were divided into three treatment groups (5, 10, and 15 watts) and one control group. All specimens were first nondestructively mechanically tested(More)
Current techniques for anterior cruciate ligament reconstruction with patellar tendon (PT) allow a measurable tension to be applied to the graft at the time of fixation. The viscoelastic nature of the PT, however, ensures that relaxation will cause the graft tension to decrease over time. To better understand this process, a primate model was used to(More)
