Development Of Software To Estimate Pressures On The Residual Limbs Of Amputees By Means Of A Pylon Mounted Transducer, Malli K. Yalamanchili Dec 2010

Development Of Software To Estimate Pressures On The Residual Limbs Of Amputees By Means Of A Pylon Mounted Transducer, Malli K. Yalamanchili

UNLV Theses, Dissertations, Professional Papers, and Capstones

The alignment of prosthesis has been recognized as one of the main factors that determine successful prosthetic outcomes for trans-tibial amputees. Alignment is defined as the relative position and orientation of the prosthetic components. Misalignment can result in changes in the position and orientation of the joints of the leg and moments experienced by them during gait, increases in energy use, and discomfort or even tissue breakdown at the socket/stump interface. Hence it is very important to align the prosthesis in correct manner. Gait analysis can be used to examine the effects of incorrect alignment of the prosthesis during gait. …

Hip Power Asymmetry In Older Adult Fallers And Non-Fallers, Lauren Grace Mcdonald Aug 2010

Hip Power Asymmetry In Older Adult Fallers And Non-Fallers, Lauren Grace Mcdonald

Boise State University Theses and Dissertations

The purpose of this study was to determine if a difference exists in hip power asymmetry between community-dwelling older adult fallers and non-fallers. Hypothesis: fallers would be more asymmetrical than non-fallers. Participants: 21 non-fallers (10 females, 11 males) and 18 fallers (14 females, 4 males) over the age of 65 (76.5 ± 6.9yrs). Method: Isokinetic peak torque during flexion, extension, abduction, and adduction at four velocities was recorded as measures of leg power. Asymmetry equaled the percent of power difference between each leg. Data analysis: Differences in age, physical activity, height, weight, and BMI were assessed …

Effects Of Obesity On The Biomechanics Of Children’S Gait At Different Speeds, Philana-Lee Gouws May 2010

Effects Of Obesity On The Biomechanics Of Children’S Gait At Different Speeds, Philana-Lee Gouws

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of the study was to investigate the relationship between body mass index (BMI) and spatio-temporal gait characteristics of overweight/obese and non-obese school-aged children (12-14 years) at two different walking speeds. Eighty-four overweight/obese (n=28; age: 13.96 ± 0.79 yrs; mass: 74.8 ± 18.21 kg; height: 159.2 ± 7.1 cm and BMI: 29.28 ± 5.64 kg/m2) and non-obese students (n=56; age: 13.72 ± 0.79 yrs; mass: 51.7 ± 10.2 kg; height: 157.8 ± 8.3 cm and BMI: 20.69 ± 2.74 kg/m2) with no present injuries were recruited. Participants were instructed to walk across an electronic walkway in each of two …

Neuromechanical Analysis Of Anterior Cruciate Ligament Risk Factors In Female Collegiate Soccer Athletes, Nelson Cortes Apr 2010

Neuromechanical Analysis Of Anterior Cruciate Ligament Risk Factors In Female Collegiate Soccer Athletes, Nelson Cortes

Human Movement Sciences & Special Education Theses & Dissertations

The anterior cruciate ligament (ACL) acts in an essential role to prevent anterior tibial displacement when experiencing jump-landing forces that are applied to the lower extremity; more than 100,000 injuries per year in the United States in sport activities that often require landing, deceleration-acceleration, cutting and pivoting actions have been reported. The aim of this study was to examine the nature of any lower limb coupling differences between a drop-jump and a side-step cutting actions, assess kinematic and kinetic differences between three tasks, and evaluate the effects of two landing techniques in biomechanical risk factors while performing two unanticipated tasks. …

The Effects Of An Anterior Cruciate Ligament Prevention Program And Retention Period On Lower Extremity Biomechanics, Ryan S. Mccann Apr 2010

The Effects Of An Anterior Cruciate Ligament Prevention Program And Retention Period On Lower Extremity Biomechanics, Ryan S. Mccann

Human Movement Sciences & Special Education Theses & Dissertations

Researchers have attempted to determine the effects of strength, flexibility, agility, and plyometric training, as well as expert feedback on biomechanical risk factors for anterior cruciate ligament (ACL) injuries. Currently, the literature lacks information regarding athletes' ability to retain adaptations made during programs designed to reduce biomechanical risk factors for ACL injuries. The purpose of this study was to determine the effects of a 10-week strength and agility program on lower extremity kinetics and kinematics of collegiate athletes immediately following training and after a 11-week retention period. Ten NCAA Division I female soccer players free of lower extremity injury, volunteered …

The Power Of Empowerment: An Icf-Based Model To Improve Self-Efficacy And Upper Extremity Function Of Survivors Of Breast Cancer, Mary Insana Fisher, Dana Howell Jan 2010

The Power Of Empowerment: An Icf-Based Model To Improve Self-Efficacy And Upper Extremity Function Of Survivors Of Breast Cancer, Mary Insana Fisher, Dana Howell

Physical Therapy Faculty Publications

Breast cancer is one of the most frequently diagnosed cancers among women. Breast cancer treatments often negatively impact the function of the arm, and quality of life and upper extremity function does not always return to a prediagnosis level. Survivors of breast cancer may also experience feelings of diminished self-efficacy related to functional deficits resulting from their physical limitations. The International Classification of Functioning (ICF) provides a framework for rehabilitation practitioners to address physical and psychological impairments, activity limitations, and participation restrictions. Patient outcomes may be improved by fostering self-efficacy through empowerment. This paper explores how the ICF model and …

Electromyographic Analysis Of Trunk Muscle Activation During A Throwing Pattern Following Rotator Cuff Mobilization, Aubrey L. Doede Jan 2010

Electromyographic Analysis Of Trunk Muscle Activation During A Throwing Pattern Following Rotator Cuff Mobilization, Aubrey L. Doede

CMC Senior Theses

Correct muscular activation of the body segments during an overhand throw is achieved when movement originates in the larger and more proximal legs and trunk and moves sequentially to the smaller, distal segments of the shoulder and arm. This sequence permits angular velocity to transfer progressively through the throw as part of an open kinetic chain. The athlete can summate angular velocity and segmental forces only if he is able to create a separation between the body segments during the movement pattern, and this separation is thus essential to effective segmental sequencing for activation of the trunk muscles to occur …
