Analyzing Change-Of-Direction And The Laterally Resisted Split Squat: Incorporating A Lateral Vector Into The Single Leg Squat, Derek Maddy

Boise State University Theses and Dissertations

Improving change of direction (COD) with the use of strength training has led to mixed results. To date, the modified single leg squat (MSLS) and the bilateral squat (BS) have been successfully used to improve COD, with equal improvement. COD is primarily performed at a 45-75° frontal plane angle; however, the MSLS and BS are performed at a 90° frontal plane angle. Based on the force vector theory, it is proposed that a more mechanically similar strength training exercise, the Laterally Resisted Split Squat (LRSS), be used. The purpose of this study is to compare COD with the LRSS, MSLS, …

Upper Limb Rehabilitation For Amputees, Michaela Ramandanes

Virginias Collegiate Honors Council Conference

It is estimated that 75% of the 30 million people that need prosthetic devices lack access to the technologies they need. This suggests a need for solutions outside of standard healthcare models. In this work we present a solution by development of a simple, safe and accessible at-home exercise program for individuals with upper limb loss. It is intended to help amputees strengthen the muscles needed to operate body-powered prostheses when muscles have atrophied from lack of use. Extensive research identified the most effective exercises to hinder overuse injuries. The exercises were compiled and published on a website with a …

Muscle Excitation Of The Lower Extremity During A Single Leg Rotational Squat In Individuals With And Without A Previous Hamstrings Strain Injury, Claudia M. Simpson

Effects Of Increased Attention Allocation On Postural Stability Related To History Of Concussion, Nicholas Reilly, Jessica Prebor, Jacquelyn Moxey, Eric Schussler

College of Health Sciences Posters

Postural instability is among the most common symptoms associated with concussion. However, clinical screenings for concussion are heavily reliant on self-reports of cognitive symptoms such as nausea and headache to determine if a full recovery has been achieved. The objective of this study was to determine if impairments of postural stability that are associated with the acute stages of concussion persist beyond the current clinical standards for determination of recovery from concussion. Fifty-four healthy participants were recruited for the study and divided based on whether they reported having no history of concussion (n = 27) or whether they had been …

Relationships Between Injury-Related Fear, Balance Self-Efficacy, And Dynamic Balance Performance In Those With Chronic Ankle Instability, Ashley M. B. Suttmiller, Kelly Johnson, Ryan S. Mccann

College of Health Sciences Posters

Interactions between sensory-perceptual and motor-behavioral impairments in individuals with chronic ankle instability (CAI) are important for successful assessment and treatment of CAI. One of the most consistently reported motor-behavioral impairments is poor reach performance in a dynamic balance task. Injury-related fear is recognized as an important sensory-perceptual impairment, and those with injury-related fears may engage in protective movement strategies found to be associated with reach deficits. Injury-related fear may also impact one’s perception of ability, or self-efficacy, which has demonstrated positive associations with balance performance in other populations, but these relationships have yet to be investigated in the CAI population. …

Schoenfeld, Gøran Paulsen, Thomas Bjørnsen, Kristoffer T. Cumming, Per Aagaard, Brian C. Clark, Truls Raastad

Publications and Research

Low-load exercise combined with blood flow restriction (BFR) is known to induce significant gains in muscle strength and size, and this mode of training is increasingly used in both healthy and clinical populations, as documented in the recent review of Patterson et al. (2019). However, since the first training studies on BFR exercise appeared about 20 years ago, there have been some concerns about its safety, in particular with regard to the potential risk for muscle damage (Wernbom et al., 2019). In a recent editorial, Wernbom et al. (2019) briefly discussed the accumulating evidence for muscle damage and rhabdomyolysis with …

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 …
