Age And Not The Preferred Limb Influences The Kinematic Structure Of Pointing Movements, Kurt W. Kornatz, Brach Poston, George E. Stelmach

Kinesiology and Nutrition Sciences Faculty Publications

In goal-directed movements, effective open-loop control reduces the need for feedback-based corrective submovements. The purpose of this study was to determine the influence of hand preference and aging on submovements during single-and two-joint pointing movements. A total of 12 young and 12 older right-handed participants performed pointing movements that involved either elbow extension or a combination of elbow extension and horizontal shoulder flexion with their right and left arms to a target. Kinematics were used to separate the movements into their primary and secondary submovements. The older adults exhibited slower movements, used secondary submovements more often, and produced relatively shorter …

Asymmetries In Dynamic Valgus Index After Anterior Cruciate Ligament Reconstruction: A Proof-Of-Concept Study, Kai Yu Ho, Andrew Murata

Physical Therapy Faculty Publications

Individuals with anterior cruciate ligament reconstruction (ACLR) are at a higher risk for subsequent anterior cruciate ligament (ACL) tears. Risk factors for ACL injuries likely involve a combination of anatomical, biomechanical, and neuromuscular factors. Dynamic knee valgus has been indicated as a possible biomechanical factor for future ACL injuries. Given that knee valgus is often accompanied by contralateral pelvic drop during single-leg activities, a dynamic valgus index (DVI) that quantifies combined kinematics of the knee and hip in the frontal plane has recently been developed. As the premise of asymmetrical DVI between limbs in the ACLR population has not been …

Effects Of Bimodal Transcranial Direct Current Stimulation On Modulation Of Spinal Circuitry In People With Chronic Post-Stroke Hemiparesis, John Patrick Gan, Rafael Cabrera, Lana Laudermilch, Benjamin Wolkenhauer

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: Stroke can lead to gait abnormalities such as foot drop. Foot drop can result from decreased corticospinal tract input to the ankle dorsiflexors and/or from exaggerated stretch reflexes on the soleus due to reduced reciprocal inhibition from spinal reflex pathways. Transcranial direct current stimulation (tDCS) attempts to modulate corticospinal tract input and spinal reflex pathways by delivering electrical signals to parts of the brain. The degree of neuromodulation from tDCS can be measured through the Hoffman Reflex (H-reflex)—a tool used to estimate alpha motor neuron excitability which is increased in individuals post-stroke. Purpose: The primary purpose of this study …

Am-Pac Basic Mobility Inpatient Short Form (Low Function) Psychometrics/Clinimetrics, Meghan Wonderling, David Miller, Selena Soria

UNLV Theses, Dissertations, Professional Papers, and Capstones

Objective: To determine whether the Activity Measure for Post-Acute Care® Basic Mobility Inpatient Short Form (Low Function) (6-clicks LF) has increased responsiveness for patients with lower levels of physical function compared to the Activity Measure for Post-Acute Care Basic Mobility Inpatient Short Form (6-clicks). Design: Retrospective cohort study using original scores and simulated scores for assessment of internal responsiveness of the 6-clicks LF compared to the 6-clicks. Simulated 6-clicks and 6-clicks LF scores were created as a hypothetical future AM-PAC® score. Results: We found a statistically significant difference between the 6-clicks and simulated 6-clicks, t=24.8, p < 0.00 [two-tailed]. The effect size was large (d=1.2, r=0.51).There was a statistically significant difference between the 6-clicks LF and simulated 6-clicks LF, t=19.7, p < 0.00 [two-tailed]. The effect size was medium (d=0.91, r=0.41). Finally, for patients with a 6-clicks score in the bottom five-percentile (n=27), we found a statistically significant difference between the 6-clicks and 6-clicks LF, t=11.9, p < 0.00 [two-tailed]. Conclusion: Among patients scoring less than 15, the 6-clicks LF has greater internal responsiveness than the 6-clicks and thus demonstrates that the new low-level questions in the 6-clicks LF better quantify low-level patients’ functional level. Research using non-simulated data should be completed in the future to confirm these findings.

Inter And Intra-Rater Reliability Of Dance Screening Tool, Kathleen Stone, Braden Waters

UNLV Theses, Dissertations, Professional Papers, and Capstones

Previous literature has indicated that injury rates of ballet and modern dancers are among the highest of any physical activity. These injuries can be detrimental to the athlete and can also result in financial burden for dance companies due to time loss related to injuries. Preventative intervention aimed at those who are most at risk for injury can be effective at reducing the cost associated with lost time due to injury. An effective approach to identifying those most at risk for dance related injuries is to administer a functional movement screen. One such movement screen is the ballet-based Dance Technique …

Essential Competencies For Occupational Therapy In End-Of-Life Care, Karmella Bognot

UNLV Theses, Dissertations, Professional Papers, and Capstones

Occupational therapists carry an abundance of expertise in helping patients and caregivers navigate the end-of-life journey. The lack of knowledge of OT’s role impacts occupational therapy utilization and service provision in hospice. It reduces opportunities for this population to increase their understanding on how to maintain quality-of-life. The more a patient is able to do lessens the burdens shouldered by the caregiver. Education on pain management and promoting comfort are typical priorities addressed; however, not enough training is focused on maximizing independence or engagement in occupations. Competencies encompass a unique set of skills, knowledge, and abilities necessary for successful performance …

Slow Walking In Individuals With Chronic Post-Stroke Hemiparesis: Speed Mediated Effects Of Gait Kinetics And Ankle Kinematics, Jing Nong Liang, Kai-Yu Ho, Yun-Ju Lee, Corey Ackley, Kiley Aki, Joshua Arias, Jassie Trinh

Physical Therapy Faculty Publications

Post-stroke rehabilitation often aims to increase walking speeds, as faster walking is associated with improved functional status and quality of life. However, for successful community ambulation, ability to modulate (increase and decrease) walking speeds is more important than walking continuously at constant speeds. Increasing paretic propulsive forces to increase walking speed has been extensively examined; however, little is known about the mechanics of slow walking post-stroke. The primary purpose of this study was to identify the effects of increased and decreased walking speeds on post-stroke kinetics and ankle kinematics. Fifteen individuals with chronic post-stroke hemiparesis and 15 non-neurologically impaired controls …
