Blood Flow Restriction Training After Patellar Instability (Brains Trial), Benjamin D. Brightwell, Austin V. Stone, Xiaojuan Li, Peter A. Hardy, Katherine L. Thompson, Brian W. Noehren, Cale A. Jacobs

Orthopaedic Surgery and Sports Medicine Faculty Publications

Background

Patellar instability is a common and understudied condition that disproportionally affects athletes and military personnel. The rate of post-traumatic osteoarthritis that develops following a patellar dislocation can be up to 50% of individuals 5–15 years after injury. Conservative treatment is the standard of care for patellar instability however, there are no evidence-informed rehabilitation guidelines in the scientific literature. The purpose of this study is to assess the effectiveness of blood-flow restriction training (BFRT) for patellar instability. Our hypotheses are that this strategy will improve patient-reported outcomes and accelerate restoration of symmetric strength and knee biomechanics necessary to safely return …

Long-Lasting Impairments In Quadriceps Mitochondrial Health, Muscle Size, And Phenotypic Composition Are Present After Non-Invasive Anterior Cruciate Ligament Injury, Steven M. Davi, Ahram Ahn, Mckenzie S. White, Timothy A. Butterfield, Kate Kosmac, Oh Sung Kwon, Lindsey K. Lepley

Center for Muscle Biology Faculty Publications

Introduction: Despite rigorous rehabilitation aimed at restoring muscle health, anterior cruciate ligament (ACL) injury is often hallmarked by significant long-term quadriceps muscle weakness. Derangements in mitochondrial function are a common feature of various atrophying conditions, yet it is unclear to what extent mitochondria are involved in the detrimental sequela of quadriceps dysfunction after ACL injury. Using a preclinical, non-invasive ACL injury rodent model, our objective was to explore the direct effect of an isolated ACL injury on mitochondrial function, muscle atrophy, and muscle phenotypic transitions.

Methods: A total of 40 male and female, Long Evans rats (16-week-old) were exposed to …

Understanding Barriers And Facilitators To Implementation Of Psychosocial Care Within Orthopedic Trauma Centers: A Qualitative Study With Multidisciplinary Stakeholders From Geographically Diverse Settings, Ana-Maria Vranceanu, Jafar Bakhshaie, Mira Reichman, James Doorley, Ryan A. Mace, Cale A. Jacobs, Mitchel Harris, Kristin R. Archer, David Ring, A. Rani Elwy

Orthopaedic Surgery and Sports Medicine Faculty Publications

BACKGROUND: Psychosocial factors are pivotal in recovery after acute orthopedic traumatic injuries. Addressing psychosocial factors is an important opportunity for preventing persistent pain and disability. We aim to identify barriers and facilitators to the implementation of psychosocial care within outpatient orthopedic trauma settings using the Consolidated Framework for Implementation Research (CFIR) and Proctor's taxonomy of implementation outcomes, and to provide implementation strategies derived from qualitative data and supplemented by the Expert Recommendations for Implementing Change.

METHODS: We conducted live video qualitative focus groups, exit interviews and individual interviews with stakeholders within 3 geographically diverse level 1 trauma settings (N …

Injury Rates In Major League Baseball During The 2020 Covid-19 Season, Brooks N. Platt, Timothy L. Uhl, Aaron D. Sciascia, Anthony J. Zacharias, Nicole G. Lemaster, Austin V. Stone

Physical Therapy Faculty Publications

Background: The 2020 Major League Baseball (MLB) season was drastically altered because of the COVID-19 pandemic. The changes included an extended layoff between March and July as well as a shortened preseason.

Purpose/Hypothesis: To determine the incidence and epidemiology of MLB injuries in the abbreviated 2020 season compared with prior seasons. We hypothesized that there was an increase in the overall injury rate in the 2020 season compared with the 2018-2019 seasons and that it equally affected all body regions.

Study Design: Descriptive epidemiology study.

Methods: The MLB transactions database was queried to find players who had been placed on …

Performance Of The Promis In Patients After Anterior Cruciate Ligament Reconstruction, Elizabeth J. Scott, Robert Westermann, Nathalie A. Glass, Carolyn Hettrich, Brian R. Wolf, Matthew J. Bollier

Orthopaedic Surgery and Sports Medicine Faculty Publications

Background: The Patient-Reported Outcomes Measurement Information System (PROMIS) is designed to advance patient-reported outcome (PRO) instruments by utilizing question banks for major health domains.

Purpose: To compare the responsiveness and construct validity of the PROMIS physical function computer adaptive test (PF CAT) with current PRO instruments for patients before and up to 2 years after anterior cruciate ligament (ACL) reconstruction.

Study Design: Cohort study (diagnosis); Level of evidence, 2.

Methods: Initially, 157 patients completed the PROMIS PF CAT, Short Form-36 Health Survey (SF-36 physical function [PF] and general health [GH]), Marx Activity Rating Scale (MARS), Knee injury and Osteoarthritis Outcome …

Muscle Activity During Maximal Isometric Forearm Rotation Using A Power Grip, Joseph Scott Bader, Michael R. Boland, Desney Greybe, Arthur J. Nitz, Timothy L. Uhl, David A. Pienkowski

Biomedical Engineering Faculty Publications

This study aimed to provide quantitative activation data for muscles of the forearm during pronation and supination while using a power grip. Electromyographic data was collected from 15 forearm muscles in 11 subjects while they performed maximal isometric pronating and supinating efforts in nine positions of forearm rotation. Biceps brachii was the only muscle with substantial activation in only one effort direction. It was significantly more active when supinating (µ = 52.1%, SD = 17.5%) than pronating (µ = 5.1%, SD = 4.8%, p < .001). All other muscles showed considerable muscle activity during both pronation and supination. Brachioradialis, flexor carpi radialis, palmaris longus, pronator quadratus and pronator teres were significantly more active when pronating the forearm. Abductor pollicis longus and biceps brachii were significantly more active when supinating. This data highlights the importance of including muscles additional to the primary forearm rotators in a biomechanical analysis of forearm rotation. Doing so will further our understanding of forearm function and lead to the improved treatment of forearm fractures, trauma-induced muscle dysfunction and joint replacements.
