Effect Of Aquastretch On Range Of Motion At Knee Joint In Total Knee Arthroplasty Patients, Raja Devinder Kochar

UNLV Theses, Dissertations, Professional Papers, and Capstones

The success of the Total Knee Arthroplasty (TKA) depends upon its functional outcomes of increase in reduction in pain, and gait ambulation and performing functional activities of daily living. Compromised range of motion, pain and weakness can reduce their ability to perform activities of daily living. Aquatic Physical Therapy may offer an alternative intervention to traditional Physical Therapy Rehabilitation and many studies have shown improvements in range of motion, swelling, pain reduction, stiffness and quality of life after TKA. AquaStretch, a relatively new form of aquatic therapy, claims to restore the functional mobility which is lost restrictions caused due to …

Examining Activity Levels And Motor Proficiency: A Comparison Of Children Who Are Overweight And At A Healthy Weight To Their Parents And Peers, Aaron Copeland, Maresa Madsen, Riley Phelps, Brandon Richards

UNLV Theses, Dissertations, Professional Papers, and Capstones

Objective: The purpose of this study was to examine relationships and differences between motor proficiency, activity level, and parental activity level in children who are at a healthy weight and children who are overweight or obese.

Methods: Forty-four children (26 children at a healthy weight and 18 children who were overweight or obese) between the ages of 8-16 (BMI: 14.3-43.6 kg/m2) and 36 parents (BMI: 18.1-44.7) participated in this study. Children and parents wore StepWatch activity monitors (SAM) to measure activity levels over a 72 hour period. Tests reflecting several determinants of motor performance were also administered to …

Effects Of Environment On Children's Motor Scores, Eligibility Status, And Administration Times, Derrick Mittelstadt, Abigail Parker, Kirsten Pickett, Heather Temkin

UNLV Theses, Dissertations, Professional Papers, and Capstones

Best practices for assessing developmental skills in young children focus on naturalistic observation in everyday settings, but the effects of environment on test scores, eligibility status and administration time have not been explored. The Peabody Developmental Motor Scales-Second Edition (PDMS-2) was administered to 34 children aged 18 to 59 months in natural and pull-out settings. PDMS-2 total, gross, and fine motor quotient (TMQ, GMQ, and FMQ) scores were significantly lower in the natural environment (p’s≤.014). Based on our results, more children would qualify for services when tested in natural environments using TMQ and GMQ scores. It also took significantly longer …

The Effect Of Acute Exercise-Induced Fatigue On Pistol Shooting Performance In Police Officers, Melissa Jean Brown

UNLV Theses, Dissertations, Professional Papers, and Capstones

Duties of police officers include apprehending suspects, which may involve foot pursuit and firing a weapon at a suspect. Previous studies in biathletes and soldiers suggest that shooting performance is compromised when fatigue is present. Purpose: To investigate the effects of exercise-induced fatigue on shooting performance in police officers. Methods: Nine police officers fired five rapid-fire shots at three targets each with a fifteen second rest period in between each trail. Officers then exercised on a cycle ergometer to 85% maximum heart rate or voluntary fatigue. The pretest shooting was repeated post-exercise. Distances of 4 shots from the center of …

Effects Of A Simulated Tennis Match On Lymphocyte Subset Measurements, Holly Kell

Masters Theses & Specialist Projects

Research has shown that maximal exercise has a significant effect on cells of the immune system. Specifically, lymphocyte count increases during exercise and decreases to a value lower than baseline following an acute exhaustive bout of exercise. The overall lymphocyte response is well characterized, however, the ability of exercise to affect lymphocyte subfractions is unknown to our knowledge. The purpose of this study was to assess and evaluate the affects of a simulated tennis match across two sessions on lymphocyte subsets.

Initial measurements such as age, height, weight, skinfold analysis, and heart rate were recorded for each player, as well …

The Effects Of Two Different Fatigue Protocols On Lower Extremity Kinematics And Kinetics During An Unanticipated Running Stop-Jump, David L. Quammen

Human Movement Studies & Special Education Theses & Dissertations

Altered neuromuscular control strategies and biomechanical movement risk factors are most likely to contribute to the increased incidence of non-contact ACL injury for female athletes. Neuromuscular control strategies and movement patterns are further altered when the effects of fatigue are present. The purpose of this study was to determine neuromechanical differences between two fatigue protocols [Slow Linear Oxidative Fatigue Protocol (SLO-FP) and Functional Agility Short-Term Fatigue Protocol (FASTFP)] when performing a running stop-jump task (RS). A sample of convenience of fifteen Division I female soccer players (age= 19.2 ± 0.8 years; height= 1.67 ± 0.05 m; mass= 61.7 ± 8.1 …

The Effects Of Two Types Of Fatigue On An Unanticipated Side-Step Cutting Task As Measured By Kinematic And Kinetic Variables, Shawn E. Lucci

Human Movement Studies & Special Education Theses & Dissertations

Fatigue has been shown to alter the neuromechanics of lower extremity. To date, no study has examined the effects of two types of fatigue on kinetics and kinematics. To determine neuromechanical differences between two fatigue protocols [Slow Linear Oxidative Fatigue Protocol (SLO-FP) and Functional Agility Short-Term Fatigue Protocol (FAST-FP)] when performing an unanticipated sidestep cutting task. Fifteen female collegiate soccer players (age=19.2±0.8 years; height=l.67±0.05m; mass=61.7±8.lkg) participated in this study. Participants were free of lower extremity injury at time of participation, and performed five successful trials of a sidestep cutting (SS) task pre and post fatigue protocols. For the SLO-FP, a …

Locus Of Control And The Age Difference In Free Recall From Episodic Memory, Paul Amrhein, Judith K. Bond, Derek Hamilton

Department of Psychology Faculty Scholarship and Creative Works

The authors investigated the relation of locus of control (LOC) to age differences in free-recall memory performance. Older and younger participants completed P. C. Duttweiler's (1984) Internal Control Index (ICI) and subsequently performed free-recall memory tasks. Compared with the younger participants, the older participants exhibited poorer recall with more intrusions and uncorrected repetition errors as well as reduced categorical clustering. For the older participants with less internal LOC, recall proportion and item-pair associative recall clustering were lower than for the older participants with more internal LOC. By contrast, the younger participants did not exhibit any LOC effects in their recall …
