Contributions Of Asymmetry And Instability To Transfer And Retention Following Locomotor Adaptation, Daniel L. Gregory
Contributions Of Asymmetry And Instability To Transfer And Retention Following Locomotor Adaptation, Daniel L. Gregory
Doctoral Dissertations
Gait asymmetry resulting from neurological injury is more costly and less stable than healthy gait. Split-belt treadmills, which drive limbs at different speeds, lead to spatial and temporal gait asymmetries, and perturb walking balance, have been used to study locomotor adaptability and learning related to asymmetry and stability. This knowledge may be leveraged to design more effective rehabilitation protocols. In experiment 1, we asked how constraining stride-rates away from preferred during split-belt walking influences learning revealed in a retention test. We found that constraints to stride rate during asymmetric walking uncovered the capacity to leverage redundant degrees-of-freedom for walking control, …

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 …

The aim of this study was to quantify balance impairments in standing in people with degenerative cervical myelopathy (PwDCM) in response to external perturbations. PwDCM have damage to their spinal cord due to degeneration of the cervical vertebral column, but little is known about balance. Balance was quantified by capturing kinetics, kinematic, and electromyographic data during standing in response to lateral waist pulls. Participants received pulls during predictable and unpredictable contexts in three stance widths at two magnitudes. In response to lateral waist pulls, PwDCM had larger center of mass excursion (P < 0.001) and delayed gluteus medius electromyography onset (P < 0.001) and peak (P < 0.001) timing. These main effects of history of myelopathy were consistent across predictability, stance width, and magnitude. A multilinear regression determined that gluteus medius peak timing + tibialis anterior peak timing most strongly predicted center of mass excursion (R2 = 0.50, P < 0.001). These data suggest that PwDCM have delays in generating voluntary and reactive motor commands, contributing to balance impairments. Future rehabilitation strategies should focus on generating rapid muscular contractions. Additionally, frontal plane postural control is regulated by the gluteus medius and the tibialis anterior, whereas other muscles (e.g. gluteus minimus, ankle invertors/evertors) not studied here may also contribute.

Does Zero Balancing positively impact occupational performance? This is a question many Occupational Therapists (OTs) ask when discerning if Zero Balancing (ZB) is an evidence-based treatment modality. Case studies from the book Experiencing the Power of Zero Balancing: Case Studies of Journeys to Health and Wholeness (Quarry & King, 2016) were reviewed and compared to the Occupational Therapy domain of practice to show clear evidence that each case study had a positive impact on occupational performance. A comparison chart shows a direct link between the occupational categories and documented evidence of improved occupational performance through practitioner observation and client feedback …
