Anodal Contralesional Tdcs Enhances Cst Excitability Bilaterally In An Adolescent With Hemiparetic Cerebral Palsy: A Brief Report, Rodrigo G. Delatorre, Ellen N. Sutter, Samuel Nemanich, Linda E. Krach, Gregg Meekins, Timothy Feyma, Bernadette T. Gillick

Occupational Therapy Faculty Research and Publications

Hemiparetic cerebral palsy (HCP), weakness on one side of the body typically caused by perinatal stroke, is characterized by lifelong motor impairments related to alterations in the corticospinal tract (CST). CST reorganization could be a useful biomarker to guide applications of neuromodulatory interventions, such as transcranial direct current stimulation (tDCS), to improve effectiveness of rehabilitation therapies. We evaluated an adolescent with HCP and CST reorganization who demonstrated persistent heightened CST excitability in both upper limbs following anodal contralesional tDCS. Results support further investigation of targeted tDCS as an adjuvant therapy to traditional neurorehabilitation for upper limb function.

Mechanisms Of The Age-Related Power Reduction In The Knee Extensor Muscles Of Men And Women, David Wrucke

Master's Theses (2009 -)

The mechanisms for the loss in limb muscle power output in old (60-79 years) and very old adults (≥80 years) and whether these mechanisms differ between older men and women are not well-understood. The aims of the thesis are to 1) compare peak power output of the knee extensor muscles between young, old, and very old adults and 2) determine the physiological mechanisms for the age-related loss of power in men compared with women. 31 young (22.9±3.0 years, 16 men), 83 old (70.4±4.9 years, 44 men), and 16 very old adults (85.8±4.2 years, 7 men) performed maximal isokinetic contractions at …

Case Studies In Physiology: Male To Female Transgender Swimmer In College Athletics, Jonathon Senefeld, Sandra K. Hunter, Doriane Coleman, Michael J. Joyner

Exercise Science Faculty Research and Publications

There is current scientific and legal controversy about sports competition eligibility regulations for transgender athletes. In this case study, we quantified performances by an elite, transgender woman (male sex, female gender identity) college swimmer who competed in both the men’s and women’s National Collegiate Athletic Association (NCAA) categories. We also contextualized her performances with respect to world-record performances and contemporary elite college swimmers. These data demonstrate that the declines in freestyle swimming performances of a transgender woman after about 2 yr of reported feminizing gender-affirming hormone treatment (0.5% for the 100 to 7.3% for the 1,650 yard distance) are smaller …

Generalized Joint Hypermobility And Lower Extremity Musculoskeletal Biomechanics In Female Athletes, Christopher F. Geiser

Dissertations (1934 -)

Generalized Joint Hypermobility (GJH), in lay terms being “double-jointed”, affects 5 to 43 percent of the general population. In severe forms, GJH impacts systems across the body, with cardiovascular, ocular, and musculoskeletal effects that can be quite debilitating. Most of the literature examining GJH is in this severely impacted group of people. However less severe forms of GJH are present in the athlete population in the same proportions, and athletes with GJH are more likely to be injured while participating in activities. They also experience greater time-loss injuries while participating in athletic activities. The movement biomechanics of those with severe …

Effect Of Chronically Suppressed Plasma Angiotensin Ii On Regulation Of The Cyp4a/20-Hete Pathway In The Dahl Salt-Sensitive Rat, Kathleen M. Lukaszewicz, John R. Falck, Julian H. Lombard

Physical Therapy Faculty Research and Publications

In Dahl salt-sensitive (SS) rats, impaired vascular relaxation can be restored by: (1) minipump infusion of a low (sub-pressor) dose of angiotensin II (ANG II) to restore physiological levels of plasma ANG II, (2) inhibition of 20-HETE production, and (3) introgression of a normally functioning renin allele from the Brown Norway rat (SS-13^BN consomic rat). Unlike SS rats, SS-13^BN rats have normal levels of ANG II on a normal-salt diet and suppressed ANG II on a high-salt (HS) diet. This study tested whether chronically low ANG II levels in SS rats upregulate cytochrome P450-4A (CYP4A) increasing the production …

Cognitive Challenge As A Probe To Expose Sex- And Age-Related Differences During Static Contractions, Hugo M. Pereira, Sandra K. Hunter

Exercise Science Faculty Research and Publications

Despite activities of daily living being frequently performed simultaneously with a cognitive task, motor function is often investigated in isolation, which can hinder the applicability of findings. This brief review presents evidence that 1) performing a cognitive challenge simultaneously with a motor task can negatively impact force steadiness and fatigability of limb muscles during a static contraction, 2) the negative impact on old adults (>65 years old), particularly older women is greater than young when a cognitive challenge is simultaneously performed with a static motor task, 3) age-related mechanisms potentially explain impairments in motor performance in the presence of …

A Complete Workflow For High Throughput Human Single Skeletal Muscle Fiber Proteomics, Amanda Momenzadeh, Yuming Jiang, Simion Kreimer, Laura E. Teigen, Carlos S. Zepeda, Ali Haghani, Mitra Mastali, Yang Song, Alexandre Hutton, Sarah J. Parker, Jennifer E. Van Eyk, Christopher W. Sundberg, Jesse G. Meyer

Physical Therapy Faculty Research and Publications

Skeletal muscle is a major regulatory tissue of whole-body metabolism and is composed of a diverse mixture of cell (fiber) types. Aging and several diseases differentially affect the various fiber types, and therefore, investigating the changes in the proteome in a fiber-type specific manner is essential. Recent breakthroughs in isolated single muscle fiber proteomics have started to reveal heterogeneity among fibers. However, existing procedures are slow and laborious, requiring 2 h of mass spectrometry time per single muscle fiber; 50 fibers would take approximately 4 days to analyze. Thus, to capture the high variability in fibers both within and between …

Bone–Patellar Tendon–Bone Autograft Harvest Prolongs Extensor Latency During Gait 2 Yr After Aclr, Naoaki Ito, Jacob J. Capin, Ashutosh Khandha, Thomas S. Buchanan, Karin Grävare Silbernagel, Lynn Snyder-Mackler

Physical Therapy Faculty Research and Publications

Purpose

Bone–patellar tendon–bone (BPTB) graft harvest for anterior cruciate ligament reconstruction alters patellar tendon properties, which inflict poor quadriceps neuromuscular function. BPTB autografts are associated with higher rates of posttraumatic osteoarthritis, which in turn is associated with pathological gait. The purpose of this study was to investigate the latency between the time of peak quadriceps activity and the peak knee flexion moment during gait, between those with BPTB grafts (n = 23) and other graft types (hamstring autograft or allografts, n = 54), 5 ± 2 months and 2 yr (25 ± 3 months) after anterior cruciate ligament reconstruction. …

Single Muscle Fibre Contractile Function With Ageing, Gregory J. Grosicki, Carlos S. Zepeda, Christopher W. Sundberg

Identifying Gait Pathology After Acl Reconstruction Using Temporal Characteristics Of Kinetics And Electromyography, Naoaki Ito, Jacob J. Capin, Ashutosh Khandha, Thomas S. Buchanan, Lynn Snyder-Mackler

Physical Therapy Faculty Research and Publications

Purpose

Asymmetrical gait mechanics after anterior cruciate ligament reconstruction (ACLR) are associated with the development of posttraumatic knee osteoarthritis. Current measures of gait mechanics have focused heavily on peak magnitudes of knee kinematics, kinetics, and joint contact forces but have seldom considered the rate of knee loading, cumulative knee load, or the timing of motor input surrounding peaks. The purpose of this study was to introduce and describe novel metrics of gait using temporal characteristics of kinetics and EMG to identify neuromuscular deficits of the quadriceps in patients after ACLR.

Methods

Gait mechanics were assessed 6 months (n = …
