Scott Monfort recently published this work as part of a National Cancer Institute funded research study led by Ajit Chaudhari, PhD and Maryam Lustberg, MD. The article in Gait & Posture discusses results from 32 breast cancer patients that participated in the pilot study. The interdisciplinary team introduced balance measurements into the oncology clinic to quantify changes in patients’ balance as they progressed through taxane-based chemotherapy. As a group, patients’ balance worsened as they continued through their chemotherapy treatment. Significant changes from baseline values (before starting chemotherapy) were observed after 1 cycle of chemotherapy (2-3 weeks) that were similar in magnitude to the effect of 40 years of aging reported in another study. The results of this study support the feasibility and usefulness of implementing objective measures into the oncology clinic.

An investigation of jogging biomechanics using the full-body lumbar spine model: Model development and validation

FBLSmodelMargaret Raabe recently just published an article in the Journal of Biomechanics detailing the development and validation of the novel musculoskeletal model she created in the modeling software OpenSim. This is the first OpenSim full body-model to include extensive trunk musculature and degrees of freedom in the lumbar spine. The full-body lumbar spine (FBLS) model provides researchers with a tool to develop more physiologically accurate full-body dynamic simulations of human movement. The paper also presents some data from jogging simulations created using the FBLS model, and shows that the model successfully estimates jogging biomechanics and muscle activation patterns similar to those previously reported experimentally in the literature. Her model will be made freely-available on the SimTK website (https://simtk.org/home/fullbodylumbar) for other researchers around the world to use to address their own research questions.

Scott Monfort wins AGGRS grant for his dissertation project

Spielman_Metria_GaitScott was recently awarded an Alumni Grants for Graduate Research and Scholarship (AGGRS) grant from OSU’s Graduate School to partially fund his dissertation research on the effect of chemotherapy-induced peripheral neuropathy (CIPN) on the postural stability of cancer patients.  This research investigates how neurotoxic chemotherapy can degrade balance and gait stability in cancer patients as well as the underlying mechanisms that contribute to this instability. The AGGRS funds will be used to help accrue patients into the study as well as to develop a quantitative test for deficits in ankle proprioception, a symptom of peripheral neuropathies, that can be easily administered in a clinical setting. This research is a step towards the long-term goal of reducing the burden that CIPN has on cancer survivors.

Congratulations, Scott!

Golf Article Highlighted in August 2014 Issue of International Journal of Sports Medicine

Mike McNally’s study, “Lower Extremity Work Is Associated with Club Head Velocity during the Golf Swing in Experienced Golfers,” was highlighted in today’s newsletter from the editor of IJSM, Hans-Joachim Appell Coriolano as a study with “high practical impact on the golf swing…I am convinced that especially those of you working closely in the applied field of sports may benefit from [this interesting paper].”

In this study, Mike found a strong association between lower extremity work during the downswing and club head velocity at impact during a full swing with the driver. These results suggest that golfers may be able to significantly increase club head velocity by utilizing their lower extremity to a greater extent.

Total lower extremity work during the downswing vs. peak club head velocity in experienced golfers with a range of handicaps.

ME PhD Candidate Greg Freisinger Is Ohio State’s First Tillman Military Scholar

This story originally appeared on the OSU MAE department web site.

U.S. Army veteran and mechanical engineering PhD candidate Greg Freisinger has been named a 2014 Tillman Military Scholar. He is one of just 60 selected from over 7,500 applicants for the prestigious award. Freisinger, who earned a Bronze Star for his service in Operation Iraqi Freedom, is the university’s first Tillman Military Scholar. Freisinger’s graduate research focus has been concentrated on biomechanics. His advisor is Assistant Professor of Orthopaedics Ajit Chaudhari, who has a courtesy appointment in The Department of Mechanical and Aerospace Engineering.

In naming Freisinger to the new class of scholars, the foundation noted, “Greg’s love of engineering led to a career as an Army Sapper and service in Thailand and Iraq, but the future of his work lies in the human body.” The newly selected class of scholars will receive $1.4 million in scholarships to pursue their higher education and continue their service.

Freisinger learned he had won the scholarship when Ohio State Interim President Joseph A. Alutto surprised him with the good news. Alutto said, “I agree, wholeheartedly, with the Pat Tillman Foundation that you have the potential to truly change the world. Your dedication to improving the lives of our country’s wounded service members is admirable. We are so proud to claim you as a member of the Ohio State family, and we thank you for your service.”

The Pat Tillman Foundation named Ohio State a University Partner earlier this year. As part of the Tillman Military Scholars program, Ohio State is part of an elite network of institutions providing innovative support services to the nation’s veterans and their families. In 2008, the Pat Tillman Foundation established the Tillman Military Scholars program to invest in military veterans and their spouses through educational scholarships, building a diverse community of leaders committed to service to others.

The foundation was created to honor Pat Tillman, a former NFL player who left his playing career to enlist in the U.S. Army after 9/11. Tillman served as an Army Ranger in Afghanistan, before being killed in active service in 2004.

A native of Maywood, N.J., Freisinger is a veteran at the rank of captain. He was a member of the Army ROTC program at Georgia Tech as an undergraduate and joined the Army after earning his B.S. in mechanical engineering. During his four years of active duty, he completed U.S. Army Ranger School and was deployed to Iraq as part of Operation Iraqi Freedom, where he was awarded the Bronze Star.

After leaving active duty, he came to Ohio State in 2010 to pursue a PhD in mechanical engineering. Now entering his fifth year of doctoral studies, Freisinger researches intra-operative knee laxity and outcomes following total knee replacement through a joint project with the Department of Orthopaedics and the Department of Mechanical and Aerospace Engineering. The knee laxity project is funded by a R01 grant from the National Institute of Arthritis and Musculoskeletal and Skin Diseases, a division of the National Institutes of Health.

After graduation, he hopes to work with military amputees in the biomechanics lab at the Brooke Army or Walter Reed Medical Centers, following his passion to advocate for wounded service members and initiate research programs that will advance the current state of rehabilitation and improve their lives.

Ohio State’s commitment to military and veteran students continues to receive national recognition. Military Times magazine calls Ohio State one of the most veteran-friendly universities in the country, and G.I. Jobsmagazine has named Ohio State one of the country’s top “Military Friendly Schools” for five consecutive years.

More than 2,200 military and veteran students, and their family members, are enrolled at Ohio State. Ohio State’s Office of Military and Veterans Services assists students with educational and academic resources. The office provides military and veteran orientations, focused academic counseling, tailored support services and the education of faculty and staff on military student issues. The Tillman Scholarship Program at Ohio State is a joint effort between the Office of Military and Veteran Student Services and the Undergraduate Fellowship Office, which assists students in applying for the award and manages the processing of applications.
