A Kinematic And Emg Dataset Of Online Adjustment Of Reach-To-Grasp Movements To Visual Perturbations, Mariusz P. Furmanek, Madhur Mangalam, Matthew Yarossi, Kyle Lockwood, Eugene Tunik

Journal Articles

Control of reach-to-grasp movements for deft and robust interactions with objects requires rapid sensorimotor updating that enables online adjustments to changing external goals (e.g., perturbations or instability of objects we interact with). Rarely do we appreciate the remarkable coordination in reach-to-grasp, until control becomes impaired by neurological injuries such as stroke, neurodegenerative diseases, or even aging. Modeling online control of human reach-to-grasp movements is a challenging problem but fundamental to several domains, including behavioral and computational neuroscience, neurorehabilitation, neural prostheses, and robotics. Currently, there are no publicly available datasets that include online adjustment of reach-to-grasp movements to object perturbations. This …

A Robust Technique For Optimal Fitting Of Roll-Over Shapes Of Human Locomotor Systems, Ganesh M. Bapat, Sara A. Myers

Journal Articles

The roll-over shape (ROS) effectively characterizes the lower limb's ability to roll forward during the single-limb support phase of human walking. ROS is modelled as an optimally fitted circular arc to the center of pressure (CoP) data transformed in the shank/leg-based local coordinate system. The commonly used method for optimal fitting of ROS is complex to implement and eliminates inherent individual variability in the ROS parameters during walking. We propose and validate a novel computerized method for optimal fitting of roll-over shapes of the lower limb during walking. Gait data of a healthy individual from Winter's book was used …

Differential Behaviour Of Distinct Motoneuron Pools That Innervate The Triceps Surae, Josh W. Cohen, Taian M. Vieira, Tanya D. Ivanova, Jayne Garland

Kinesiology Publications

It has been shown that when humans lean in various directions, the central nervous system (CNS) recruits different motoneuron pools for task completion; common units that are active during different leaning directions, and unique units that are active in only one leaning direction. We used high-density surface electromyography (HD-sEMG) to examine if motor unit (MU) firing behaviour was dependent on leaning direction, muscle (medial and lateral gastrocnemius; soleus), limits of stability, or whether a MU is considered common or unique. Fourteen healthy participants stood on a force platform and maintained their center of pressure in five different leaning directions. HD-sEMG …

Development And Preliminary Testing Of A Walkassist Device With Dynamic Support, Simon Detmer, Gita Regmi, Kaitlyn Boellner, Ann Reinthal, Hanz Richter

Summer Research

In the past decade, usage of walking aids in the senior population has increased by 50 percent and is expected to double by 20501 . Walkers are used as a temporary aid to encourage mobility after surgery or fracture, but they often become permanent aids2 . In the United States, about 12 percent of the elderly population use walkers1. Walkers are prescribed to reduce the load on lower limbs and/or to improve balance and stability. However, longer usage of walkers leads to low physical function and low self-confidence. Walker users typically have forward leaning posture due to load transfer from …

The Effects Of Common Low-Load Blood Flow Restriction Training Protocols On Muscle Excitation And Fatigue, Taylor M. Aldeghi

Honors Undergraduate Theses

Low-load blood flow restriction (LLBFR) training has been shown to elicit greater increases in muscle hypertrophy and strength compared to traditional low-load training, yet few studies have compared the effectiveness of different LLBFR protocols. To our knowledge, no previous study has compared the acute neuromuscular changes induced by two common LLBFR protocols: 30-15-15-15 repetitions (BFR-75) and four sets of repetitions performed to volitional failure (BFR-F). Therefore, the purpose of this study was to use surface electromyography (sEMG) to compare changes in muscle excitation and fatigue during BFR-75 and BFR-F protocols. Ten women (mean ± SD age = 22 ± 3.5 …

The Relationship Between The Population's Perception Of Herniated Intervertebral Disks And Their Known Physical Presentation, Jonah D. Gant

Honors Undergraduate Theses

The second most common lumbosacral diagnosis in the United States is a herniation or prolapse of the intervertebral disc. Individuals with herniated discs can have a wide variety of clinical presentations, ranging from asymptomatic to severe spinal cord compression and pain. Studies suggest that an individual’s pre-existing perception of a condition is likely to influence their course of recovery. Currently, perceptions the general public holds regarding the consequences of disc herniation is unknown. Therefore, the purpose of this study was to assess current views regarding disc herniations in the general population with their reported prevalence and clinical outcome. This was …

Automatic Posture Correction Utilizing Electrical Muscle Stimulation, Ravi Kiran Kattoju

Electronic Theses and Dissertations, 2020-2023

Habitually poor posture can lead to repetitive strain injuries that lower an individual's quality of life and productivity. Slouching over computer screens and smart phones, asymmetric weight distribution due to uneven leg loading, and improper loading posture are some of the common examples that lead to postural problems and health ramifications. To help cultivate good postural habits, researchers have proposed slouching, balance, and improper loading posture detection systems that alert users through traditional visual, auditory or vibro-tactile feedbacks when posture requires attention. However, such notifications are disruptive and can be easily ignored. We address these issues with a new physiological …

Exploration Of Warm-Up Protocols On Muscular Fatigue, Sahil Kapadia

Honors Undergraduate Theses

Muscular dystrophy is a genetically linked myopathy with no cure available. The lack of a cure makes early detection and treatment of muscular dystrophy imperative. When reviewing protocols examining muscular fatigue at submaximal isometric contractions, proper warm-up appeared to be absent and could have caused skewed results and conclusions. This study examines the effects of implementing a warm-up protocol before fatiguing trials. In this study, 10 adult subjects conducted fatiguing protocols with the right rectus at submaximal isometric contractions. The warm-up period included a light walk along with contractions at 20% and 33% of maximal voluntary isometric contraction (MVIC) levels. …
