Use Of Non-Surgical Mechanical Splinting For Patients With Carpal Tunnel Syndrome, Abi Ramirez, Buck Willis, Howard Hoffberg

International Journal of Exercise Science: Conference Proceedings

Compress of the median nerve causes severe pain and paresthesia in Carpal Tunnel Syndrome (CTS). Over 2,000,000 Americans suffer from Carpal Tunnel Syndrome, making it the most common peripheral neuropathology affecting the U.S. Continual compression over time degrades the median nerve that brings sensation of movement and feeling for the wrist. The purpose of this study was to compare change in symptoms of CTS after use of a non-surgical dynamic splinting device. Methods: A retrospective analysis was accomplished for patients diagnosed with CTS who were treated with prolonged passive stretching in dynamic splinting for this pathology (N=304). The Levine Katz …

Preliminary Data Regarding How Wheelchair Axle Position Effects The Energy Cost Of Assistants Pushing Wheelchairs Designed For Low-Resource Settings., Matthew K. Sturm, Josh Vanleer, Nathan Lowe, Karen Rispin

International Journal of Exercise Science: Conference Proceedings

A study at Letourneau University was performed to compare the energy cost of pushing wheelchairs with differing axle positions in relation to the occupant’s center of gravity (COG). In less-resourced areas of the world, powered wheelchairs are rarely feasible, requiring an assistant to push the chair. Often these assistants themselves are disabled, making any means of minimizing energy cost imperative. Research has indicated that as the rear axle comes closer to the COG, the energy cost of self-propelling the chair decreases. We hypothesized that able-bodied assistants pushing wheelchairs could provide valuable insight into the effect of axle position on energy …

Comparison Of Ascending And Descending Pyramidal Loading Using The Bench Press, Joey R. Miller

International Journal of Exercise Science: Conference Proceedings

Individuals that weight train want to know the best way to accumulate a greater amount of volume in a workout to potentially increase muscle hypertrophy and strength. The distribution of the training load during a weight training session could be an important variable in determining total session training volume. The purpose of this study was to examine the importance of load distribution on training volume over three weight training sets utilizing the bench press. We hypothesized that the descending load pyramidal (DP) scheme of distributing training load will produce greater training volumes than the opposite ascending load pyramidal (AP) scheme. …

International Journal of Exercise Science: Conference Proceedings

Each year, approximately 2.8 million adults die from complications related to obesity (World Health Organization, 2011). One in three adults aged 20 years or older is obese, and 6% are morbidly obese. This problem is increasing at an alarming rate in young adults, and 20.5% of college students are classified as being overweight based upon their body mass index (BMI) (Adderley-Kelly, 2007). The purpose of this study was to increase knowledge about evidence-based, effective interventions that will enable college-aged, pre-nursing students to attain physical and mental well-being. The participants (N=24) were freshman and sophomore pre-nursing majors who were randomized into …

Cost Of Rolling On Rough And Smooth Ground For Assistants Pushing The Motivation Rough Terrain And Whirlwind Roughrider Wheelchairs, Nicole Leman, Nathan Lowe, Anna G. Mcdonnel, Karen Rispin

International Journal of Exercise Science: Conference Proceedings

In less-resourced settings, powered wheelchairs are rarely available for users who cannot self-propel[1]. These users must rely on somebody, usually family members or friends, for assistance to push them across variable terrain[2]^,[3]. In situations where people with disabilities are grouped together, assistants may themselves be disabled. Provision of mobility for the wheelchair user may be a great physiological cost for the assistant. Objective outcomes measures can provide valuable feedback to manufacturers which can constructively influence wheelchair design modification^3,4. We hypothesized that measuring the energy cost for an assistant pushing two types of …

Using Curb And Figure-Eight Skills Tests To Compare Maneuverability Of The User Assistant Team In The Motivation Rough Terrain Wheelchair And The Whirlwind Roughrider Wheelchair, Emily Tutt, Anna Mcdonnel, Nicole Leman, Karen Rispin

International Journal of Exercise Science: Conference Proceedings

ABSTRACT

Some wheelchair users who cannot self-propel use powered chairs. In less-resourced settings powered chairs may not be available and users may rely on assistants to push them. In these environments, obstacles similar to curbs are common and living spaces are small^1,2. Efficiency and maneuverability are two key aspects of wheelchair performance in such settings¹ .Validated skills tests for measuring wheelchair performance over obstacles and in tight spaces include timed exercises involving curbs and figure-eight patterns³. We hypothesized that some chairs designed for less-resourced settings would be easier than others for assistants to push in …

The Effect Of Herbal Diet On Skeletal Muscle Mass After Resistance Training In Rats, Junyoung Hong, Kijeong Kim, Aram Yoon, Joon Young Park, Sukho Lee

International Journal of Exercise Science: Conference Proceedings

Resistance training has been well established as an effective strategy for muscle hypertrophy, increase in skeletal muscle mass and strength. Herbal diet has been introduced as an alternative treatment to alleviate muscle atrophy and therapeutic intervention. However, there is little evidence on the effect of herbal diet on skeletal muscle mass. To investigate whether herbal diet affects skeletal muscle mass after resistance training in rats. Twenty-four rats were randomly divided into 3 groups: 1) Control (CON, N=8), 2) Resistance training (RT, N=8), 3) RT+Herb (RTH, N=8). Resistance training was performed every other day for 8 weeks using ladder climbing. The …

Comparing Three Methods Of Measuring Skin Temperature During Exercise In A Hot, Humid Environment, Randall R. Williams, Adam S. Venable, Brian K. Mcfarlin

International Journal of Exercise Science: Conference Proceedings

Exercise in a hot, humid environment substantially increases the physiological stress of exercise. Most of the techniques that are currently used to monitor changes in skin temperature have been in use for more than 20 years with little innovation. The purpose of the present study was two-fold: 1) to compare three techniques for measuring skin temperature (wired skin electrode, wireless temperature data logger, and thermal imaging) and 2) to compare and contrast these measures in men and women completing 45-min of cycling in a hot (39±2°C), humid (45±5% RH) environment. The CPHS committee approved all procedures described in this report …

Deptor Expression Correlates With Muscle Protein Synthesis, Kevin L. Shimkus, Elyse V. Wudeck, Yasaman Shirazi-Fard, Mats I. Nilsson, Nicholas P. Greene, Harry A. Hogan, James D. Fluckey

International Journal of Exercise Science: Conference Proceedings

Mammalian target of rapamycin (mTOR) has long been declared a focal point of muscle protein synthesis. mTORC1 (an mTOR complex consisting of mTOR, raptor, PRAS40, and mLST8) has been associated with regulation of protein translation in muscle, altering expression and activity levels of key downstream targets S6K1 and eIF-4E-BP1. mTORC1 has been shown to be affected by various stimuli, including nutritional status, growth factors, and mechanical loading. But in past incidents we have found disconnects in muscle protein synthesis and mTOR signaling, stimulating discussions that mTOR content and activation alone may not be able to fully account for muscle protein …
