Isometric Hip Strength And Dynamic Stability Of Individuals With Chronic Ankle Instability, Ryan S. Mccann, Brenn A. Bolding, Masafumi Terada, Kyle B. Kosik, Ian D. Crossett, Phillip A. Grobble

Rehabilitation Sciences Faculty Publications

Context: Compared with individuals who have a history of lateral ankle sprain (LAS) without markers of chronic ankle instability (CAI; LAS copers) and healthy people, those with CAI often exhibit neuromuscular impairments and dynamic-stability deficits at the hip. However, the influence of hip-strength deficits on dynamic stability remains unknown.

Objective: To compare isometric hip strength and dynamic stability in individuals with or without CAI and examine the degree of dynamic-stability variance explained by isometric hip strength.

Design: Case-control study.

Setting: Research laboratory.

Patients or Other Participants: Sixty individuals (47 women, 13 men; age = 23.7 +/- 4.6 years, height = …

Grip Force Control Using Prosthetic And Anatomical Limbs, Michael S. Trujillo, Daniel M. Russell, David I. Anderson, Marilyn Mitchell

Rehabilitation Sciences Faculty Publications

Introduction

Skillful object manipulation in various activities of daily living requires accurate and economical modulation of grip force, yet experimental studies investigating grip force using a prosthesis are lacking. The purpose of this study was to compare grip force output between two types of upper-limb prosthetic prehensors. We hypothesized a relationship between grip force output and the muscular tension needed to control the prehensor.

Materials and Methods

Ten able-bodied participants attempted to produce a static target grip force using a voluntary opening and voluntary closing prosthetic simulator and their anatomical hand. The target forces were 0.49 N, 4 N, and …

Athletic Training Student Core Competency Implementation During Patient Encounters, Julie M. Cavallario, Bonnie L. Van Lunen, Johanna M. Hoch, Matthew Hoch, Sarah A. Manspeaker, Shana L. Pribesh

Rehabilitation Sciences Faculty Publications

Context: Health care research evidence suggests that early patient encounters (PEs), as well as the purposeful implementation of professional core competencies (CCs), for athletic training students (ATSs) may be beneficial to their ability to provide care. However, no investigators have related facets of the clinical education experience with CC implementation as a form of summative assessment of the clinical experience.

Objective: To determine the relationship between the frequency and length of PEs, as well as the student's role and clinical site during PEs, and the students' perceived CC implementation during these encounters.

Design: Cross-sectional study.

Setting: Professional athletic training program, …

Normative Functional Performance Values In High School Athletes: The Functional Pre-Participation Evaluation Project, James A. Onate, Cambrie Starkel, Daniel R. Clifton, Thomas M. Best, James Borchers, Ajit Chaudhari, Eric Schussler, Bonnie L. Van Lunen

Rehabilitation Sciences Faculty Publications

Context: The fourth edition of the Preparticipation Physical Evaluation recommends functional testing for the musculoskeletal portion of the examination; however, normative data across sex and grade level are limited. Establishing normative data can provide clinicians reference points with which to compare their patients, potentially aiding in the development of future injury-risk assessments and injury-mitigation programs.

Objective: To establish normative functional performance and limb-symmetry data for high school-aged male and female athletes in the United States.

Design: Cross-sectional study.

Setting: Athletic training facilities and gymnasiums across the United States.

Patients or Other Participants: A total of 3951 male and female athletes …

Postprofessional Athletic Training Students' Perceptions Concerning The Health Care Competencies, Cailee E. Welch Bacon, Bonnie L. Van Lunen, Dorice A. Hankemeier

Rehabilitation Sciences Faculty Publications

Context: Over a decade ago, the Institute of Medicine indicated that all health care professionals should be educated in several health care competency areas (quality improvement, health care informatics, interprofessional education and collaborative practice, evidence-based practice, and patient-centered care). Despite this initiative, athletic training has only recently incorporated these competencies throughout education.

Objective: To assess postprofessional athletic training students' perceived abilities and importance regarding 6 core competencies.

Design: Cross-sectional. Setting: Self-reported paper survey. Patients or Other

Participants: A total of 221 from a convenience sample of 258 postprofessional athletic training students (85.7%) completed the survey (82 males, 138 females; age …

Inter-Rater Agreement And Validity Of A Tackling Performance Assessment Scale In Youth American Football, Eric Schussler, Richard J. Jagacinski, Susan E. White, Ajit M. Chaudhari, John A. Buford, James A. Onate

Rehabilitation Sciences Faculty Publications

Background: Long term neurologic injury and concussion have been identified as risks from participation in American football. Altering tackling form has been recommended to reduce the risk of neurologic injury caused by head accelerations when tackling. The purpose of this research is to determine the inter-rater agreement and validity of the Qualitative Youth Tackling System (QYTS), a six-item feedback scale to correct tackling form, when utilized by novice and expert raters.

Hypothesis: Experienced raters will have higher levels of agreement with each other and with motion capture when compared to novice raters. Methods: Both novice and experienced raters viewed video …

The Effect Of Tackling Training On Head Accelerations In Youth American Football, Eric Schussler, Richard J. Jagacinski, Susan E. White, Ajit M. Chaudhari, John A. Buford, James A. Onate

Rehabilitation Sciences Faculty Publications

Background: Many organizations have introduced frameworks to reduce the incidence of football related concussions through proper equipment fitting, coach education, and alteration of tackling technique.

Purpose: The purpose of this study was to examine the effects of training in a vertical, head up tackling style on the number of head accelerations experienced while tackling in a controlled laboratory situation. The authors hypothesized that training in a head up tackling technique would reduce the severity of head acceleration experienced by participants.

Design: Controlled Laboratory Study.

Methods: Twenty-four participants (11.5 ± 0.6 years old, 60.5 ± 2.2 in, 110 ± 18.4 lbs.) …
