A Biomechanical And Physiological Signal Monitoring System For Four Degrees Of Upper Limb Movement, Allison R. Goldman
A Biomechanical And Physiological Signal Monitoring System For Four Degrees Of Upper Limb Movement, Allison R. Goldman
Electronic Thesis and Dissertation Repository
A lack of adherence to prescribed physical therapy regimens in improper healing results in poor outcomes for those affected by musculoskeletal disorders (MSDs) of the upper limb. Societal and psychological barriers to proper adherence can be addressed through the system presented in this work consisting of the following components: an ambulatory biosignal acquisition sleeve, an electromyography (EMG) based motion repetition detection algorithm, and the design of a compatible capacitive EMG acquisition module.
The biosignal acquisition sleeve was untethered, unobtrusive to motion, contained only modular components, and collected biomechanical and physiological sensor data to form full motion profiles of the following …
Dynamic Calibration Of Emg Signals For Control Of A Wearable Elbow Brace, Taylor Stanbury
Dynamic Calibration Of Emg Signals For Control Of A Wearable Elbow Brace, Taylor Stanbury
Electronic Thesis and Dissertation Repository
Musculoskeletal injuries can severely inhibit performance of activities of daily living. In order to regain function, rehabilitation is often required. Assistive devices for use in rehabilitation are an avenue explored to increase arm mobility by guiding therapeutic exercises or assisting with motion. Electromyography (EMG), which are the muscle activity signals, may be able to provide an intuitive interface between the patient and the device if appropriate classification models allow smart systems to relate these signals to the desired device motion.
Unfortunately, there is a gap in the accuracy of pattern recognition models classifying motion in constrained laboratory environments, and large …

Development Of An Emg-Based Muscle Health Model For Elbow Trauma Patients, Emma Farago
Electronic Thesis and Dissertation Repository
Musculoskeletal (MSK) conditions are a leading cause of pain and disability worldwide. Rehabilitation is critical for recovery from these conditions and for the prevention of long-term disability. Robot-assisted therapy has been demonstrated to provide improvements to stroke rehabilitation in terms of efficiency and patient adherence. However, there are no wearable robot-assisted solutions for patients with MSK injuries. One of the limiting factors is the lack of appropriate models that allow the use of biosignals as an interface input. Furthermore, there are no models to discern the health of MSK patients as they progress through their therapy.
This thesis describes the …
Examining Motor Unit Stability Of First Dorsal Interosseous (Fdi) And Biceps Brachii (Bb) Muscles In Healthy And Older Adults Using Decomposition-Based Quantitative Electromyography (Dqemg), Igor Angelovski
Electronic Thesis and Dissertation Repository
Aging of the human neuromuscular system is associated with gradual decline in motor unit (MU) number leading to denervation of muscle fibers and subsequent compensatory reinnervation from surviving MUs. Lower limb muscles exhibit age-related increased MU instability (measured electrophysiologically), however not much is known regarding MU stability of aging upper limb muscles. The purpose of this study was to examine agerelated MU loss in upper limb muscles (first dorsal interosseous [FDI] and biceps brachii [BB]) and the impact on MU stability in younger and older healthy subjects using electrophysiological near fiber analysis from decomposition-based quantitative electromyography (DQEMG). FDI and BB …
Functional Anatomy Of Palmar Musculature, Colin W. Moore
Functional Anatomy Of Palmar Musculature, Colin W. Moore
Electronic Thesis and Dissertation Repository
The palmaris longus (PL) and palmaris brevis (PB) are upper limb muscles considered atavistic remnants of those found in animal species. Despite their use in surgical grafting and tendon transfer procedures, the functional role of the PL and PB have not been investigated comprehensively in vivo. Using a multi-modal experimental approach consisting of indwelling fine wire electromyography (EMG), ultrasonography and immunohistochemical muscle staining techniques, the function of the PL and PB in the hand was evaluated both in in vivo and in situ.
The purpose of Study 1 was to determine whether the PL provides synergistic contributions to …
