Methods: Nine participants took part in this randomized study in which EMG data was collected during 4 exercise trials of 10 repetitions each on the right shoulder. EMG activity was monitored …

Balance Comparison Of Open- And Closed-Back Shoes, Tiffany Hemberger, Sara Henderson, Eric Loiland

Physical Therapy Scholarly Projects

A growing number of healthcare professionals have been choosing to wear an open-back shoe rather than a traditional closed-back shoe in the workplace. Healthcare professionals incorporate dynamic balance and quick reactions during direct patient interaction. The purpose of the study was to determine if dynamic balance would be affected in healthcare professionals when wearing open-back shoes versus closed-back shoes.

Thirty-two healthcare professionals or students of healthcare professions (28 females and 4 males) were recruited for this study. Subjects ranged in age from 20 to 62 years (mean age 28.2 years), with the majority being physical therapists or physical therapy students. …

Role Of Z-Coilª Shoes On Plantar Pressure Forces During Short Distance Walking, Tyler Volle, Michael Rider, Brett Jenks, Benjamin Deubner

Physical Therapy Scholarly Projects

Purpose: The Z-CoiL ® company has marketed a shoe that is advertised to decrease pressure and attenuation of forces on the foot, ankle, and other lower extremity joints. Evidence based studies, however, are lacking in support of this claim. The purpose of this study was to compare the peak pressure distributed onto the bottom of the foot from heel strike to midstance when walking bare foot, using a personal athletic shoe, and using a Z-CoiL ® shoe.

Subjects: Thirty subjects without any current history of orthopedic pathologies were examined in this study. Fourteen subjects were excluded from final data analysis, …

Top 10 Positional-Release Therapy Techniques To Break The Chain Of Pain, Part 1, Timothy E. Speicher, David O. Draper

All PTHMS Faculty Publications

Positional-Release Therapy (PRT) is a treatment technique that is gaining popularity. The purpose of this two-part column is to briefly explain the theory and application of PRT. Then, we will present our top 10 list of what we think are the most commonly treated tender points by athletic therapists, five in Part 1 and five in Part 2, along with general tips, patient self-treatments, and adjunctive techniques.

PRT, originally termed strain–counterstrain, is a therapeutic technique that uses tender points (TPs) and a position of comfort (POC) to resolve the associated dysfunction. Essentially, PRT is the opposite of stretching.

PRT is …

Low Back Pain In Police Officers, Jennifer Gwyn Arts

Masters Theses

Low back pain (LBP) is something that police officers deal with on a daily basis. The purpose of this research was to explore whether police officers have a higher incidence of LBP than the general population and to explore what factors officers believe contribute to the LBP they experience. Surveys were made available to all police departments in Kent County and all sworn officers were asked to participate. The difference between LBP experienced by police officers (60.2%) and that experienced by the general population (60-90%) was not found to be significant. The top two answers given by officers as to …

Effects Of Sprint Training On Extrarenal Potassium Regulation With Intense Exercise In Type 1 Diabetes, Alison R. Harmer, Patricia A. Ruell, Michael J. Mckenna, Donald J. Chisholm, Sandra K. Hunter, Jeanette M. Thom, Norman R. Morris, Jeff R. Flack

Exercise Science Faculty Research and Publications

Effects of sprint training on plasma K⁺ concentration ([K⁺]) regulation during intense exercise and on muscle Na⁺-K⁺-ATPase were investigated in subjects with Type 1 diabetes mellitus (T1D) under real-life conditions and in nondiabetic subjects(CON). Eight subjects with T1D and seven CON undertook 7 wk of sprint cycling training. Before training, subjects cycled to exhaustion at 130% peak O₂ uptake. After training, identical work was performed. Arterialized venous blood was drawn at rest, during exercise, and at recovery and analyzed for plasma glucose, [K⁺], Na⁺ concentration ([Na⁺]), catecholamines, …

Effect Of Keyswitch Design Of Desktop And Notebook Keyboards Related To Key Stiffness And Typing Force, Marcia J. Bufton, Richard W. Marklin, Mark L. Nagurka, Guy G. Simoneau

Mechanical Engineering Faculty Research and Publications

This study aimed to compare and analyse rubber-dome desktop, spring column desktop and notebook keyboards in terms of key stiffness and fingertip typing force. The spring-column keyboard resulted in the highest mean peak contact force (0.86N), followed by the rubber dome desktop (0.68N) and the notebook (0.59N). All these differences were statistically significant. Likewise, the spring-column keyboard registered the highest fingertip typing force and the notebook keyboard the lowest. A comparison of forces showed the notebook (rubber dome) keyboard had the highest fingertip-to-peak contact force ratio (overstrike force), and the spring-column generated the least excess force (as a ratio of …

The Role Of Lower Leg Muscle Activity In Blood Pressure Maintenance Of Older Adults, Michelle M. Masterson, Amy L. Morgan, Christine E. Multer, Daniel Cipriani

Purpose. Age-associated muscle weakness, postural instability, and orthostatic hypotension have been identified as contributing factors to falls , but the relationships among them are not clear. Therefore, the purpose of this study, a two-way factorial design, was to investigate the differences in lower extremity (LE) muscle activity, blood pressure (BP), and heart rate (HR) between young and older individuals in an upright position. Methods. Ten young males (20-24 yrs.) and 10 older males (65-82 yrs.) stood for 15 minutes while BP, HR, and LE electromyography (EMG) were recorded at one minute intervals . A two-way ANOVA was used …

Influences On Health Related Quality Of Life In Community Dwelling Adults Aged 60 Years And Over, Hilary Beth Greenberger

Theses and Dissertations

Interest in patient-reported health care outcomes such as health related quality of life (HRQL) has increased dramatically over the past two decades. Typically, HRQL has been conceptualized as having at least three domains: physical, psychological, and social functioning. Although research has attempted to identify factors that influence HRQL,few studies have simultaneously examined how various factors impact HRQL in the elderly. The purpose of this study was to develop and test a causal model to identify factors influencing HRQL. The constructs and observed variables hypothesized to influence HRQL included medical burden, housing satisfaction, socioeconomic status,religion/spirituality, age, gender, and marital status.Three hundred …
