Fabrication Of Ankle-Foot Orthoses Using Selective Laser Sintering Technology, Allison Kinney, M. C. Faustini, Richard R. Neptune, R. H. Crawford, S. J. Stanhope

Mechanical and Aerospace Engineering Faculty Publications

Passive dynamic ankle-foot orthoses (AFOs) are often prescribed to improve gait performance for those with various neuromuscular disorders. Designs and materials used for AFOs range from simple polypropylene braces to advanced custom carbon fiber dynamic AFOs that passively store and release mechanical energy during gait. AFO designs vary in the shape and length of the foot component as well as the stiffness and length of the tibial component, depending on the desired functional outcomes. However, the current fabrication technology is not ideally suited for refined customization of AFO characteristics to optimize performance, or for rapid lowcost, high volume manufacturing and …

Development And Analysis Of A Software Package To Quantify In Vivo Polyethylene Wear After Total Hip Arthroplasty, Allison Kinney, Catherine G. Ambrose

Mechanical and Aerospace Engineering Faculty Publications

Since the first total hip arthroplasty (THA) in 1938, THA evolved and developed into one of the major concentrations of orthopaedic research. The typical hip implant device used today incorporates a femoral and an acetabular component that serve to replicate the anatomical and mechanical functions of the natural hip joint. However, several problems exist that can effect the function of the implant device. Wear in the polyethylene liner of the acetabular component of the total hip replacement device is known as one of the major factors that affects the longevity of total hip replacement devices. Both manual and computer-aided techniques …

Tibial Rotation In Anterior Cruciate Ligament (Acl)-Deficient And Acl-Reconstructed Knees, Nikolaos Stergiou, Stavros Ristanis, Constantina O. Moraiti, Anastasios D. Georgoulis

Journal Articles

Excessive tibial rotation has been documented in ACL deficiency during walking. ACL reconstruction has been unable to correct this abnormality in activities that are more demanding than walking and involve both anterior and rotational loading of the knee. These findings persist regardless of graft selection for the ACL reconstruction [bone-patellar tendon-bone (BPTB) or semitendinosus-gracilis (ST/G)]. Based on this research work, we propose a theoretical perspective for the development of osteoarthritis in both the ACL deficient and the ACL reconstructed knee. We propose that excessive tibial rotation will lead to abnormal loading of the cartilage areas that are not commonly loaded …

Ground Reaction Force Differences Between Running Shoes, Racing Flats, And Distance Spikes In Runners, Suzanna Jean Logan

Theses and Dissertations

To measure the differences in ground reaction forces between running shoes, racing flats, and distance spikes, twenty intercollegiate distance runners ran across a force plate at 6.7m/s (for males) and 5.74m/s (for females) in each of the three types of shoes. In order to control for differences in foot strike, only subjects who had a heel strike were included in the data analysis (N=16). Repeated-measures ANOVA and Tukey's post-hoc test (p<0.05) revealed loading rate and impact peak to be significantly increased in the flats and spikes compared to running shoes. Stiffness in spikes was significantly higher than in running shoes. Stance time in spikes and flats was decreased. These results can be used to better inform competitive runners, coaches, and trainers of the risks and performance benefits when determining the frequency and duration of the use of competitive footwear in training.

Emotional Health And Weight Gain: A Prospective Study Of Middle-Aged Women, Ann Bahr

Theses and Dissertations

The objective of this study was to investigate the extent to which risk of gaining weight or body fat is affected by emotional health in women. A secondary objective was to determine the influence of age, baseline weight and body fat, physical activity (PA), energy intake, and changes in PA and energy intake, on the relationship between emotional health and gains in weight and body fat. The study was a prospective cohort investigation over 20 months of 256 healthy, non-obese females (age: 35-45 y, BMI < 30 kg/m2). All subjects were assessed for several variables using objective measurements at baseline and again at 20 months. Emotional health was assessed using the General Well-Being Schedule. Body fat percentage was indexed using the Bod Pod. PA was measured objectively using MTI (CSA) accelerometers, and energy intake was measured using weighed, 7-day food records. The results of the study demonstrated that risk of gains in weight and body fat were no greater in depressed women compared to their counterparts. However, 171 (66.8%) subjects demonstrated less than positive (LTP) emotional health at baseline, and 37.4% of these subjects gained weight during the 20-month study. Conversely, 85 (33.2%) subjects had positive emotional health at baseline, but only 23.5% gained weight over the investigational period. With no variables controlled, women with LTP emotional health had 59% greater risk of weight gain over the study period than women with positive emotional health (RR 1.59, 95% CI = 1.04-2.44). Women with LTP emotional health were at no greater risk of gains in body fat percentage than women with positive emotional health (RR 0.96, 95% CI = 0.70-1.33). After adjusting for each potential confounder individually, risk of gaining weight or body fat did not change. However, after adjusting for all of the potential confounders simultaneously, risk of weight gain was weakened (RR 1.43, 95% CI = 0.93-2.21). These results seem to demonstrate that middle-aged women with LTP emotional health may be at increased risk of gaining weight compared to women with positive emotional health.

Differential Neuromuscular Training Effects On Acl Injury Risk Factors In"High-Risk" Versus "Low-Risk" Athletes, Gregory D. Myer, Kevin R. Ford, Jensen L. Brent, Timothy E. Hewett

Kinesiology and Health Promotion Faculty Publications

BACKGROUND: Neuromuscular training may reduce risk factors that contribute to ACL injury incidence in female athletes. Multi-component, ACL injury prevention training programs can be time and labor intensive, which may ultimately limit training program utilization or compliance. The purpose of this study was to determine the effect of neuromuscular training on those classified as "high-risk" compared to those classified as "low-risk." The hypothesis was that high-risk athletes would decrease knee abduction moments while low-risk and control athletes would not show measurable changes.

METHODS: Eighteen high school female athletes participated in neuromuscular training 3x/week over a 7-week period. Knee kinematics and …

Methods To Improve The Reliability Of The Functional Reach Test In Children And Adolescents With Typical Development, Kathleen G. Volkman, Nikolaos Stergiou, Wayne A. Stuberg, Daniel Blanke, Julie Stoner

Journal Articles

Purpose: Test-retest reliability of the Functional Reach Test was examined in children with typical development by comparing standard and alternate methods.

Methods: Eighty subjects ages seven to 16 years were tested and 69 retested for four methods of Functional Reach Test (ie, one-arm finger-to-finger, two-arm finger-to-finger, one-arm toe-to-finger, and two-arm toe-to-finger). Intraclass correlation coefficients and limits of agreement were calculated.

Results: Intraclass correlation coefficients were high in toe-to-finger measurement methods (0.97– 0.98) for the entire group and specific age groups (00.83–0.93). Toe-to-finger methods were more reliable than finger-to-finger methods. The two-arm toe-to-finger method had the best limis of agreement with …

Derivation Of An Age And Weight Handicap For The 5k Run, Paul M. Vanderburgh, Lloyd L. Laubach

Health and Sport Science Faculty Publications

The adverse effect of increasing age and/or body weight on distance run performance has been well documented. Accordingly, nearly all five kilometer (5K) road races employ age categories and, sometimes, a heavier body weight classification. Problems with such conventions include small numbers of runners within older age categories and the advantage given to the lightest runners within each weight category. We developed a 5K Handicap (5KH), a model that calculates an adjusted run time based on the inputs of actual 5K run time, age, and body weight for men and women. This adjusted time, then, can be compared between runners …

Transcranial Doppler Estimation Of Cerebral Blood Flow And Cerebrovascular Conductance During Modified Rebreathing, Jurgen A.H.R. Claassen, Rong Zhang, Qi Fu, Sarah Witkowski, Benjamin D. Levine

Exercise and Sport Studies: Faculty Publications

Clinical transcranial Doppler assessment of cerebral vasomotor reactivity (CVMR) uses linear regression of cerebral blood flow velocity (CBFV) vs. end-tidal CO2 (PETCO2) under steady-state conditions. However, the cerebral blood flow (CBF)-PETCO2 relationship is nonlinear, even for moderate changes in CO2. Moreover, CBF is increased by increases in arterial blood pressure (ABP) during hypercapnia. We used a modified rebreathing protocol to estimate CVMR during transient breath-by-breath changes in CBFV and PETCO2. Ten healthy subjects (6 men) performed 15 s of hyperventilation followed by 5 min of rebreathing, with supplemental O2 to maintain arterial oxygen saturation constant. To minimize effects of changes …

Herodicus, The Father Of Sports Medicine, Anastasios D. Georgoulis, Irini-Sofia Kiapidou, Lamprini Velogianni, Nikolaos Stergiou, Arthur Boland

Journal Articles

Herodicus (fifth century bc) is the first person in the history of medicine who actually combined sports with medicine. He used to be a sports teacher, who later studied medicine and managed to succeed Euryphon in the medical school of Cnidos, one of the most prominent in ancient Greece together with its neighbor medical school of Cos (Hippocrates’ home). In Cnidos Herodicus formed his own theoretical perspective of medicine. He considered, namely, bad health to be the result of imbalance between diet and physical activity and for this reason he recommended strict diet, constant physical activity and regular training. He …
