Acute Effects In Postural Sway As A Result Of Self-Myofascial Release On The Lower Extremities In Collegiate Female Athletes., Mackenzie Melton, Andrew Shim, Monica Dial, Guilherme M. Cesar

International Journal of Exercise Science

International Journal of Exercise Science 17(1): 274-284, 2024. Myofascial release is a popular therapy technique used to manipulate connective muscle tissue to become more pliable. The maintenance of body posture relies on mechanoreceptors located in connective tissue, thus manipulation of connective tissue should affect postural control. The effects of this phenomenon have not been well studied, leaving room for this investigation. PURPOSE: To observe if postural sway scores changed before and after foam rolling proximal (quadriceps and hamstrings) in comparison to distal (calves) muscles. METHODS: Thirty-six, college-aged female athletes (age 20.39 ± 0.25 years, mass 68.70 ± 1.97 kg, height …

Quantifying Balance: Computational And Learning Frameworks For The Characterization Of Balance In Bipedal Systems, Kubra Akbas

Dissertations

In clinical practice and general healthcare settings, the lack of reliable and objective balance and stability assessment metrics hinders the tracking of patient performance progression during rehabilitation; the assessment of bipedal balance plays a crucial role in understanding stability and falls in humans and other bipeds, while providing clinicians important information regarding rehabilitation outcomes. Bipedal balance has often been examined through kinematic or kinetic quantities, such as the Zero Moment Point and Center of Pressure; however, analyzing balance specifically through the body's Center of Mass (COM) state offers a holistic and easily comprehensible view of balance and stability.

Advancing The Assessment And Treatment Of Signs And Symptoms Of Parkinson Disease, David Scott May

WUSM Theses and Dissertations – All Programs

People with PD often report signs and symptoms that negatively impact quality of life. Among these are balance difficulties, impaired gait, and FOG. New treatment and assessment strategies for these signs and symptoms are needed, as current techniques are limited. While new treatment and assessment strategies continue to emerge, gaps in knowledge persist. Deep brain stimulation (DBS) has been utilized in many people with PD throughout the 21st century, but it is unknown specifically how subthalamic nucleus deep brain stimulation (STN-DBS) affects balance. Alternative treatment strategies, such as a dental mouthpiece, have also been proposed. While dental mouthpieces have shown …

Theses and Dissertations

Virtual reality (VR) is becoming increasingly important in balance training. However, the influence of VR generated visual perturbation, through the novel virtual moving room paradigm, is unknown. Thirty healthy individuals had their static balance assessed on a BTrackS balance plate under eight different conditions: baseline eyes open and eyes closed with and without VR, unexpected toward and away moving VR perturbation, and expected toward and away moving VR perturbation. Multiple statistical analyses were conducted, and the results revealed significantly higher postural sway variables in the unexpected moving toward trials compared to the other moving room conditions; significantly higher postural sway …

A Mechanistic View Of Mental Fatigue And Motor Performance: Implications Of Sex, Physical Activity And Sleep Quality, Katie L. Kowalski

Electronic Thesis and Dissertation Repository

Sustained attention on a task leads to the development of mental fatigue, which is characterized by increases in perceived fatigue and associated with declines in submaximal exercise performance. However, the neuromuscular mechanisms underlying the relationship between mental fatigue and declines in motor performance are unclear and it is unknown if there are sex-specific responses to mental fatigue. Accordingly, the overall objective of this dissertation was to examine sex-specific differences in the impact of mental fatigue on neuromuscular function and motor performance in young adults. This objective was achieved through three studies by investigating neuromuscular function of the tibialis anterior (electrophysiological …

Description, Reliability And Validation Of A Novel Ground-Reaction-Force-Triggered Protocol For Simulation Of Tripping Perturbations During Gait, James Anderson, Samuel Hadley, Denise Ng, Catrina Fabian

UNLV Theses, Dissertations, Professional Papers, and Capstones

Tripping is a common cause of falls across different age populations particularly in older adults. Concerns regarding the validity of simulated-fall research protocols reside in the current literature. The purpose of this study was to develop a novel treadmill-based tripping protocol that allowed researchers to deliver unanticipated tripping perturbations during walking with a high level of timing precision. The protocol utilized a side-by-side split-belt treadmill instrumented with force platforms. Treadmill belt acceleration profiles (two levels of perturbation severity: small perturbation vs large perturbation) were delivered unilaterally when the tripped leg bore 20% of the body weight during early stance. Peak …

Identification Of Chronic Postural Stability Impairments Associated With History Of Concussion, Nicholas Reilly

Rehabilitation Sciences Theses & Dissertations

Concussion is the most common form of traumatic brain injury (TBI). However, there is a disproportionate level of understanding between the acute and chronic impairments associated with traumatic brain injury. Specifically, problems maintaining balance during standing and walking are cardinal signs of acute concussion, but the temporal extent to which postural control deficits remain following the initial injury are not well defined or understood. The purpose of the projects composing this dissertation was to examine the long-term effects of a prior history of concussion on static (i.e. standing) and dynamic (i.e. gait) postural control. To address this, healthy adults aged …

Postural Control Is Altered In Females With Excessive Medial Knee Displacement, Joao R. Vaz, Nikolaos Stergiou, Ana Diniz, Ricardo Dinis, Pedro Pezarat-Correia

Journal Articles

Knee valgus motion observed during landing tasks has been proposed as a predictor of future knee injury. It mainly involves excess motion in the frontal plane and is known to be greater in individuals with excessive medial knee displacement (MKD). This affects postural control during sports manoeuvres. Previous sports medicine-related research suggests that the nature of these fluctuations provide rich and more sensitive information to identify risk of (re)injury. We aimed to investigate the fluctuations of the centre of pressure (CoP) in individuals with and without excessive MKD. Twenty females (12 controls; 8 excessive MKD) were instructed to perform single-leg …

The Function Of The Intrinsic Foot Muscles During Turns And Mediolateral Shifts In Balance, Hope E. Kircher

Senior Honors Projects, 2020-current

Purpose: Atrophy of the intrinsic foot muscles (IFM) has been associated with foot deformity, balance deficiencies, and plantar ulceration in patients with diabetes. Nevertheless, little is understood regarding the function of the intrinsic foot muscles responsible for abduction of the toes, and no study has directly assessed the role of the abductors in maintaining mediolateral balance or foot alignment and integrity during turning and other nonlinear activities. The purpose of this study was to determine the activation levels of abductor hallucis (ABDH), abductor digiti minimi (ABDM), the first (PDIO1) and third (PDIO3) dorsal interossei, and flexor digitorum brevis (FDB) during …

A Modified Lean And Release Technique To Emphasize Response Inhibition And Action Selection In Reactive Balance, David A.E. Bolton, Manhoud Mansour

Kinesiology and Health Science Faculty Publications

Assessment of reactive balance traditionally imposes some type of perturbation to upright stance or gait followed by measurement of the resultant corrective behavior. These measures include muscle responses, limb movements, ground reaction forces, and even direct neurophysiological measures such as electroencephalography. Using this approach, researchers and clinicians can infer some basic principles regarding how the nervous system controls balance to avoid a fall. One limitation with the way in which these assessments are currently used is that they heavily emphasize reflexive actions without any need to revise automatic postural reactions. Such an exclusive focus on these highly stereotypical reactions would …

Stop-Signal Reaction Time Correlates With A Compensatory Balance Response, Garrett Rydalch, Hayden B. Bell, K. L. Ruddy, David A.E. Bolton

Kinesiology and Health Science Faculty Publications

Background

Response inhibition involves suppressing automatic, but unwanted action, which allows for behavioral flexibility. This capacity could theoretically contribute to fall prevention, especially in the cluttered environments we face daily. Although much has been learned from cognitive psychology regarding response inhibition, it is unclear if such findings translate to the intensified challenge of coordinating balance recovery reactions.

Research question

Is the ability to stop a prepotent response preserved when comparing performance on a standard test of response inhibition versus a reactive balance test where compensatory steps must be occasionally suppressed?

Methods

Twelve young adults completed a stop signal task and …

Staying Upright By Shutting Down? Evidence For Global Suppression Of The Motor System When Recovering Balance, Caleigh Goode

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Background: When automatic, yet unwanted action is quickly inhibited, short-lived suppression throughout the motor system ensues. This type of response inhibition causing an all-over motor suppression effect is referred to as global suppression. Although response inhibition is essential for behavioral flexibility, widespread motor suppression may delay action reprogramming. In reactive balance control, even fleeting suppression of the motor system could interfere with our ability to adapt compensatory reactions quickly enough to avoid a fall.Whether this concept of global suppression is occurring in situations that pose a postural threat is undetermined.

Research Question: Is muscle activity in …

The Impact Of Power Training On Balance And Visual Feedback Removal, Juliana Bouton

Senior Honors Theses

Because power training has been known to augment stability, the purpose of this study was to assess whether the removal of visual input affects lower limb muscle power production in young women who are resistance trained to the same degree it affects the untrained. This provided insight as far as the need for resistance training protocols in a largely untrained visually impaired population. To study this, fourteen college-aged female participants (18-23 years) performed a seated double-leg press on a leg sled machine, isolating power production of the lower limbs. After establishing baselines, which involved finding an average of power produced …

The Impact Of Flexibility On Balance In Rifle Athletes, Ileia Nagelkirk

Williams Honors College, Honors Research Projects

Research has shown that there may be a connection between flexibility and balance when evaluating fall risk in older adults and flexibility’s effect on a balance test (Emilio, Hita-Contreras, Jiménez-Lara, Latorre-Román, & Martínez-Amat, 2014); Overmoyer & Reiser, (2015). Balance is an important component of many sport movements, and has been shown to be particularly important in shooting performance in both novice and Olympic rifle athletes (Mononen, Konttinen, Viitasalo, Era, 2007; Ball, Best, Wrigley, 2003). The purpose of this study was to find if there was a relationship between a rifle athlete’s flexibility and their balance ability, to determine if flexibility …
