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 …

Effects Of Quadruped Movement In An Individual With Chronic Stroke: A Case Study, Maureen Romanow Pascal, Emily Connell, Alyssa Pratti, Kristina Russell

Student Research Poster Presentations 2022

Background/Purpose: Neuromuscular dysfunction encompasses a wide variety of conditions that impact proper muscle functioning. One common condition resulting in neuromuscular dysfunction is a cerebrovascular accident (CVA) which can disrupt sensory, motor, visual and language systems. The resulting combination of impairments can cause limitations in activity performance and restrict participation across domains. In addition, muscle weakness is widely recognized as a major contributing factor to decline in function. Literature is showing that rehabilitation programs focusing on development of core strength with emphasis on repetition, intensity and novelty are critical for recovery of motor function. The purpose of this research was to …

The Fit-For-Purpose Model: Conceptualizing And Managing Chronic Nonspecific Low Back Pain As An Information Problem, Benedict M. Wand, Aidan G. Cashin, James H. Mcauley, Matthew K. Bagg, Gemma M. Orange, G. Lorimer Moseley

Physiotherapy Papers and Journal Articles

Chronic nonspecific low back pain (CNSLBP) is a complex and multifaceted problem. The following Perspective Piece tries to help make sense of this complexity by describing a model for the development and maintenance of persistent low back pain that integrates modifiable factors across the biopsychosocial spectrum. The Fit-for-Purpose model (FFPM) posits the view that chronic nonspecific low back pain represents a state in which the person in pain holds strong and relatively intransient internal models of an immutably damaged, fragile, and unhealthy back, and information that supports these models is more available and trustworthy than information that counters them. This …

In-Season Rehabilitation Program Using Blood Flow Restriction With Therapy For Two Decathletes With Patellar Tendinopathy: A Case Report, Tyler Cuddeford, Jason Brumitt

Faculty Publications - College of Physical Therapy

Background and Purpose: Patellar tendinopathy is an overuse injury experienced primarily by athletes; especially athletes who participate in sports that involve frequent jumping. Therapeutic exercise is the primary conservative treatment for patients with this condition. However, some patients with patellar tendinopathy may be unable to tolerate the loading that occurs during exercise. The use of blood flow restriction (BFR) therapy for patients with patellar tendinopathy may allow the athlete to exercise with a lower load while still experiencing the physiological benefits associated with training at a higher intensity. The purpose of this case report was to detail the outcomes from …

Post-Stroke Cognitive Impairments And Responsiveness To Motor Rehabilitation: A Review, Jennapher Lingo Vangilder, Andrew Hooyman, Daniel S. Peterson, Sydney Y. Schaefer

Physical Therapy Faculty Articles and Research

Purpose of Review
This review discusses the prevalence of cognitive deficits following stroke and their impact on responsiveness to therapeutic intervention within a motor learning context.

Recent Findings
Clinical and experimental studies have established that post-stroke cognitive and motor deficits may impede ambulation, augment fall risk, and influence the efficacy of interventions. Recent research suggests the presence of cognitive deficits may play a larger role in motor recovery than previously understood.

Summary
Considering that cognitive impairments affect motor relearning, post-stroke motor rehabilitation therapies may benefit from formal neuropsychological testing. For example, early work suggests that in neurotypical adults, cognitive function …

Mediolateral Damping Of An Overhead Body Weight Support System Assists Stability During Treadmill Walking, M. Bannwart, S. L. Bayer, Niklas König Ignasiak, M. Bolliger, G. Rauter, C. A. Easthope

Physical Therapy Faculty Articles and Research

Background

Body weight support systems with three or more degrees of freedom (3-DoF) are permissive and safe environments that provide unloading and allow unrestricted movement in any direction. This enables training of walking and balance control at an early stage in rehabilitation. Transparent systems generate a support force vector that is near vertical at all positions in the workspace to only minimally interfere with natural movement patterns. Patients with impaired balance, however, may benefit from additional mediolateral support that can be adjusted according to their capacity. An elegant solution for providing balance support might be by rendering viscous damping along …

Association Between Patient Ability In Activities Of Daily Living At Hospital Admission And Key Indicators, Stephanie Rosen, Amber Steele

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: Illness and inactivity in the hospital frequently leads to disability that can reduce quality of life and increase costs. Early identification of people with limitations in activities of daily living (ADL) who are at risk for poor outcomes such as increased length of stay (LOS), hospital acquired conditions (i.e., falls and pressure injuries (PIs)), and discharge away from home can facilitate appropriate intervention. The Activity Measure for Post-Acute Care Inpatient Activity Short Form (AM-PAC IASF), a reliable and valid tool to measure ADL limitations, is scored at admission for all patients in our hospital.

Walking Kinematics In Young Children With Limb Loss Using Early Versus Traditional Prosthetic Knee Prescription Protocols, Mark Daniel Geil, Zahra Safaeepour, Brian Giavedoni, Colleen Coulter

Faculty Articles

The traditional treatment protocol for young children with congenital or acquired amputations at or proximal to the knee prescribes a prosthesis without a working knee joint, based in part on the assumption that a child learning to walk cannot properly utilize a passively flexing prosthetic knee component. An alternative to this Traditional Knee (TK) protocol is an “Early Knee” (EK) protocol, which prescribes an articulating prosthetic knee in the child’s first prosthesis, during development of crawling and transitioning into and out of upright positions. To date, no study has compared samples of children with limb loss at or proximal to …

Comparison Of Pre- And Post-Operative Shoulder Muscle Emg Profiles In Reverse Total Shoulder Arthroplasty Patients, Emily Lau, Sreten Franovic, Noah Kuhlmann, Eric C. Makhni Md, Stephanie Muh Md

Medical Student Research Symposium

Background: Deltoid muscle function is central in reverse total shoulder arthroplasty (RTSA) function; however, there is limited information available regarding changes in deltoid activity before and after surgery. Few tests exist to evaluate specific muscle metrics pre and post operatively. Surface Electromyographic (EMG) is non-invasive and allows for observation of motions with multifaceted analysis of movement with minimal patient demand. Understanding the changes in shoulder muscle activation, namely in the deltoid, in patients pre and post-RTSA can further advance understanding of the procedure and rehabilitation efforts.

Methods: Nine individuals were recruited for this study: all patients underwent RTSA by a …

Muscle Activation Patterns During Movement Attempts In Children With Acquired Spinal Cord Injury: Neurophysiological Assessment Of Residual Motor Function Below The Level Of Lesion., Darryn A Atkinson, Laura Mendez, Natalie Goodrich, Sevda C Aslan, Beatrice Ugiliweneza, Andrea L Behrman

Physical Therapy Collection

Introduction: Characterization of residual neuromotor capacity after spinal cord injury (SCI) is challenging. The current gold standard for measurement of sensorimotor function after SCI, the International Society for Neurological Classification of Spinal Cord Injury (ISNCSCI) exam, seeks to determine isolated intentional muscle activation, however many individuals with SCI exhibit intentional movements and muscle activation patterns which are not confined to specific joint or muscle. Further, isolated muscle activation is a feature of the neuromuscular system that emerges during development, and thus may not be an appropriate measurement standard for children younger than 6.

Methods: We utilized neurophysiological assessment …

Physiotherapy Is Associated With Improvements In Gait And Balance In Individuals With Cognitive Impairment: A Retrospective Analysis, Steven Jackson, Elbert Chen, Jason Phan

UNLV Theses, Dissertations, Professional Papers, and Capstones

BACKGROUND: Evidence suggests that individuals with cognitive impairment (CI) exhibit significant motor impairments; however, these motor impairments receive little treatment attention compared to more prominent CI. Moreover, there is a lack of evidence about physiotherapy (PT) in individuals with CI. OBJECTIVE: The purpose of this study was to determine if PT was effective at improving gait and balance in individuals with Alzheimer disease (AD), vascular dementia (VaD), dementia with Lewy bodies (DLB), and mild cognitive impairment (MCI). METHODS: Retrospective data of 173 individuals with CI conditions and an initial evaluation for PT were extracted from electronic records from January 2016 …

Innovative Care Of Individuals In The Athletic Training Room: A Case Series, Kathryn E. Young

Senior Honors Projects, 2010-2019

This work follows three unique cases of athletic injuries and/or injuries in patients. These cases were selected because of the innovative nature of the rehabilitation process conducted by the sports medicine team via the athletic training room or the unique nature of the injury/case.

The first is a concussion sustained from a motor vehicle accident in a collegiate female thrower. This is unique because it’s a non-sport related concussion handled as an athletic trainer would handle a sports related concussion. It also demonstrates a new unique protocol for concussion management.

The second case is a patient with two complete anterior …

The Tailoring Of National Guidelines For Upper Extremity Post-Stroke Rehabilitation: A Concept In Use., Salem F. Alatawi

Internet Journal of Allied Health Sciences and Practice

Background: In Saudi Arabia, national evidence-based clinical guidelines (NCG) were created based for healthcare interventions. However, clinicians appear to be slow to incorporate the evidence into practice. As a result, there exists a time-gap between the gathering and presentation of evidence for best practice and the use of that evidence by clinicians. It becomes, therefore, imperative to investigate the gap between the research evidence and clinical practice. The knowledge to action (KTA) framework is available to facilitate the implementation of research evidence. This framework incorporates the theory of tailoring, a concept that is intended to create a fit between …
