Development And Evaluation Of A Simple Human Body Link Model Considering The Degrees-Of-Freedom Of Shoulders, Mizuki Takeda, Yuki Saito, Kaiji Sato

Progress in Scale Modeling, an International Journal

Modeling of the human body is widely utilized in the field of human–robot interaction, warranting the development of a simple model to measure and recognize the human body movements. To this end, a two-dimensional (2D) human body link model in the sagittal plane has been used to represent the human body with rotating joints and links connecting these joints. The joint positions can be determined by using the coordinates of a limited number of points on the links and estimated using a few sensor outputs when the links are of constant length. However, models with constant link lengths may result …

Biomechanics Of Softball Pitching And The Relationship Between Functional Field Tests And Pitching Performance, Joshua Spencer Johnson

Theses and Dissertations

Over 2 million people in the United States play softball alone, yet softball literature in exercise science and biomechanics is still sparse. Research that exists for softball pitching has focused on injury mechanisms and prevention, with a small portion of the literature reporting on performance. Studies have reported evidence suggesting that vertical ground reaction forces of the stride leg are related to pitch velocity. However, no studies have investigated the role of the stride leg during the initial launch phase of the pitch. Research has investigated kinematics such as pelvic and thoracic rotation during the pitch, but no research has …

Assessing The Kinematics And Kinetics About The Knee With An Isokinetic Dynamometer And Force Plates During Field-Based And Lab-Based Trials., Samantha Ann Searles

Theses and Dissertations

The incidence rate in knee injuries has increased over the last 20 years, with women at a 2-8 times higher incidence rate compared to men. This is likely a result of lower neuromuscular control of the trunk, generating less hip muscle activation, and more reliance on the quadriceps, alongside reduced hip, knee, and dorsiflexion angles, paired with increased knee valgus angles, ground reaction forces (GRF), hip adduction, and knee rotation upon landing from jumps. The focus of this study is to determine if knee kinetics and kinematics during field- and lab-based trials are associated with knee injury predictors. Theoretically, if …

Effect Of Hearing Status On Modified Balance Error Scoring System Performance, Matthew Brancaleone, Claire Akard, Jaclyn Caccese

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

OBJECTIVE
Concussion assessments typically include evaluations of self-reported symptoms, neurocognitive function, and postural control. Specifically, postural control is often assessed using the modified Balance Error Scoring System (mBESS). Although normative mBESS data exist, they may not be appropriate for all athletes, such as those who are deaf or hard-of-hearing (D/HoH). Given the relationship between the cochlea and the vestibular system, athletes who are D/HoH may exhibit differences in postural control due to potential vestibular dysfunction. Therefore, the objective of this study was to compare mBESS performance between athletes who are D/HoH and athletes who are hearing.

The Influence Of Intrinsic Foot Muscles In Modulating Foot Shape Relative To Substrate And The Efficacy Of Different Strengthening Approaches, Luke R. Lotsis

Masters Theses, 2020-current

Cross-sloped surfaces create an asymmetrical substrate for foot contact, introducing a slip force within the transverse plane and a gravitational pull within the coronal plane that increases the tendency to topple downslope. To maintain stability, the foot must make structural adjustments across the hindfoot, midfoot, forefoot, and hallux. In chapter 1, I investigated how IFMs respond to varying substrate conditions and balance demands, providing insight into their functional role in maintaining stability and adapting foot structure in static and dynamic locomotor tasks. Twenty-four healthy adults participated in a series of dynamic walking trials on flat, cross-sloped and sandy substrates and …

Effects Of Altered Somatosensory Input On Gait Kinetics And Kinematics Via Different Footwear In Individuals With Chronic Post-Stroke Hemiparesis, Daniela Casillas, Lesley Ruiz

UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose/Hypothesis: Individuals with post-stroke hemiparesis walk with significant asymmetries, leading to slow, effortful walking, and a high risk of falls. One contributing factor is altered sensation on the plantar surface. Studies examining altered somatosensory input via insoles, vibration and other tactile stimuli observed improvements in hemiparesis gait. This study investigates whether altering somatosensory input through different footwear can affect kinetics, kinematics and muscle activity during walking post-stroke. We hypothesized the barefoot conditions would have increased dorsiflexion (heel-strike, swing), increased plantarflexion during toe-off, increased muscle activity and kinetics, compared to memory foam conditions.

Participants: 13 individuals with chronic post-stroke hemiparesis (4F/9M, …

Following a two-week washout period (if needed), subjects were randomly assigned to receive either 6.8g of β-alanine daily or a placebo. After the supplementation period, subjects performed a standardized exhaustive squat protocol (10 sets of 10 repetitions at 60% of their estimated 1RM). Venous blood samples were collected pre-exercise, 24-hours post, and 72-hours post …

Torque Efficacy Of Cadmus Bracket Design Using Clear Aligners, Joseph Soderberg

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction: Clear aligner therapy (CAT) is an alternative option for clinicians to use for orthodontic treatment as opposed to fixed appliances. Many patients prefer clear aligner therapy due to its esthetic looks, removability, ease of oral hygiene, and comfort. Clear aligner companies boast to clinicians that it can be used more efficiently and effectively than fixed appliances in many orthodontic cases. Although these claims have been made, there is a lack of evidence to prove that clear aligner therapy is more efficient or effective. This research will focus on torque control. This project is designed around a new, pre-manufactured attachment …
