UNLV Theses, Dissertations, Professional Papers, and Capstones
INTRODUCTION: According to the National Institute of Health consensus, Osteoporosis causes premature disability in approximately 44 million people (National Institute of Health [NIH], 2001), 80% of this population being women (Ulrich, Georgiou, Gillis, & Snow, 1999). This chronic disease causes 1.5 million fractures annually, 700,000 occurring at the spine (NIH, 2001). One prevention technique developed in recent years is to build a high peak bone mass during growth and in young adult life (Almstedt, Canepa, Ramirez, & Shoepe, 2011). Several publications positively correlate an increase in BMD with increased amounts of exercise. Bone mineral density can be observed through DEXA …

Four Weeks Of Controlled Frequency Breathing Training Reduces Respiratory Muscle Fatigue In Elite College Swimmers., Alex Robert Burtch 1991-
Electronic Theses and Dissertations
Controlled frequency breathing (CFB) is a common swim training modality that involves holding one’s breath for ~12 strokes before taking another breath. We sought to examine the effects of CFB training on reducing respiratory muscle fatigue (RMF). Elite swimmers (n = 25) were divided into either the CFB or a group that breathed regularly, every ~3rd stroke. The training intervention included 16 sessions of 12x50-m repetitions with either breathing pattern. RMF was defined as the drop in maximal inspiratory mouth-pressure (MIP) between rest and 46 seconds after a 200 yard free-style swimming race (~114 seconds). Pooled results demonstrated a reduction …

The Effect Of Balance-Based Torso-Weighting On Mobility, Gait, Balance, Postural Control, And Falls Efficacy In Mobility Limited Older Adults, Jennifer L. Vincenzo
Graduate Theses and Dissertations
Exercise is a known intervention to prevent fall risk among older adults; however, adherence is poor. Therefore, it is of interest to determine if other interventions improve function and decrease fall risk among older adults. Balance-Based Torso-Weighting (BBTW) is a non-exercise intervention that improves functional measures among adults with multiple sclerosis, yet the effectiveness of BBTW has not been assessed among older adults without progressive neurological disorders. We conducted a double-blind, randomized study to analyze the effect of BBTW on functional measures and falls efficacy among community-dwelling, mobility limited older adults after 5 days of wearing BalanceWear® for 4 hours …

All Dissertations
Temporomandibular joint (TMJ) disorder affects over 10 million people in the US each year. The signs and symptoms of temporomandibular joint disorders (TMDs) include limited mouth opening, clicking and locking of the jaw, and significant pain in the craniofacial region. In patients who seek treatment for TMDs, over 70% have TMJ disc displacement related to disc degeneration. The TMJ disc is interposed between the mandible condyle and the glenoid fossa of the temporal bone. The disc reduces contact stresses within the joint and provides lubrication to the joint. It is generally believed that pathological mechanical loadings, such as sustained jaw …
