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 …

Neurophysiological Assessments Of Brain And Spinal Cord Associated With Lower Limb Functions In Children With Cerebral Palsy: A Protocol For Systematic Review And Meta-Analysis, Leonard Ubalde, Jing Nong Liang

Physical Therapy Faculty Publications

Background: Task-dependent neurophysiological adaptations in people with cerebral palsy have been examined using various techniques such as functional magnetic resonance imaging, peripheral nerve stimulation in order to assess H-reflexes, and transcranial magnetic stimulation. This activity-dependent plasticity is hypothesized to improve specific gross motor function in individuals with cerebral palsy. Although these adaptations have been examined extensively, most studies examined tasks utilizing the upper limbs. The aim of this review is to assess the neurophysiological adaptations of the central nervous system in individuals with cerebral palsy during lower limb functional tasks. Methods: A systematic review and meta-analysis will be conducted to …

The participants were 20 healthy males aged 20 to 30 years old, with ten professional and ten amateur batters. Eye gaze position, head, shoulder, trunk, and pelvis angular velocity, and ground reaction forces were recorded. The results showed that professional batters rotated segments more rhythmically and efficiently than the amateur group. Firstly, the professional group spent less time in the preparation stages. Secondly, the maximum angular velocity timing of each segment of the professional …

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 …

Sound Effects On Standing Postural Strategies In The Elderly Via Frequency Analysis Approach, Yun-Ju Lee, Chang-Hsu Chen, Chao-Che Wu, Yu-Jung Chen, Jing-Nong Liang

Physical Therapy Faculty Publications

Sound and sound frequency could improve postural sway in the elderly. The power spectrum intervals of the center of pressure (COP) displacement are associated with different postural regulations, which could be revealed by frequency analysis. The aim of the study was to investigate the effects of sound on dual-tasking postural control and conduct frequency analysis to distinguish postural regulations in the elderly. Fifteen young and 15 older healthy participants were instructed to stand on a force platform and performed the Purdue Pegboard test while hearing 50 dB sounds with sound frequencies of 250 Hz, 1000 Hz, 4000 Hz, or no …

Altered Achilles Tendon Morphology In Individuals With Chronic Post-Stroke Hemiparesis: A Case Report, Jing Nong Liang, Kai-Yu Ho

Physical Therapy Faculty Publications

Background: Individuals post-stroke walk slowly and with more effort, which puts them at higher risks for falls. The slow walking speed results from insufficient propulsive forces generated by the paretic leg. Current rehabilitative efforts to improve walking function target increasing propulsive forces, but overlook the muscle-tendon unit. Case presentations: Two individuals with chronic post-stroke hemiparesis are presented. In both individuals post-stroke, paretic ankle plantarflexors presented with increased muscle tone. Gait kinetics revealed asymmetric propulsive forces, specifically, insufficient propulsive forces by the paretic legs, consistent with previous literature. Sonography revealed increased thickness of paretic Achilles tendon at the calcaneal insertion, in …

Eleven young healthy participants stood on the force platform and waited for the instruction of taking a step while experiencing a pendulum perturbation applied at the lateral side of the right shoulder. Eight experimental conditions were conducted by two levels of step side (right or left), two levels of perturbation (with or without), and two levels of landing orientation (forward …

Improving Outcomes By Implementing A Pressure Ulcer Prevention Program (Pupp): Going Beyond The Basics, Amparo Cano, Debbie Anglade, Hope Stamp, Fortunata Joaquin, Jennifer A. Lopez, Lori Lupe, Steven P. Schmidt, Daniel L. Young

Physical Therapy Faculty Publications

A multidisciplinary process improvement program was initiated at the University of Miami Hospital (UMH) in 2009 to identify the prevalence of hospital-acquired pressure ulcers (HAPU) at the institution and to implement interventions to reduce the incidence of HAPU. This deliberate and thoughtful committee-driven process evaluated care, monitored results, and designed evidence-based strategic initiatives to manage and reduce the rate of HAPU. As a result all inpatient beds were replaced with support surfaces, updated care delivery protocols were created, and monitored, turning schedules were addressed, and a wound, ostomy, and continence (WOC) nurse and support staff were hired. These initial interventions …
