Gamified Gait Rehabilitation Via Real-Time Biofeedback And Adaptive Hip-Exoskeleton Control, Mariya Huzaifa Tohfafarosh

Theses

Gait impairments arise from systemic diseases, age-related degeneration, musculoskeletal dysfunctions, or neurological conditions. While traditional rehabilitation can be effective, they often face challenges such as high costs, inaccessibility, and low patient engagement. To address these challenges, my work introduces a virtual reality-based rehabilitation (VRBR) system, integrating real-time motion and electromyographic (EMG) muscle activation feedback with a gamified virtual environment for enhanced adaptability and engagement. The system includes a custom-designed hip-exoskeleton that provides adaptive spring-like assistance or resistance, supporting both mobility-impaired users and strength training. Assistance levels can be tuned to match the user's progress. Additionally, a custom pressure insole was …

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, …
