Where Are They Now? Ms. Caitlin Schneider was the first student researcher in the AIMS Laboratory as a Junior in Spring of 2013. Scheduled to complete her master’s degree in Kinesiology at the University of Texas of the Permian Basin, Caitlin is currently working as a physical therapy aide to support herself while she completes her degree. Caitlin’s ultimate goal is to become a physical therapist and is applying to Doctor of Physical Therapy programs in North Carolina and Texas. With a series of research abstracts and presentations under her belt, research was not new to Caitlin when she began her master’s program in Kinesiology. She is currently investigating the effects of different running strike patterns on joint forces and powers within the lower extremity. Caitlin has expressed an interest in publishing her master’s thesis work in a peer-reviewed journal once it is completed.

AIMS Lab Research Presentations Researchers from the AIMS Laboratory have had an exciting time in the Spring 2015 semester, presenting at three different conferences throughout the semester.

Human Movement Science Research Conference At the Human Movement Science Research Conference hosted by UNC-Chapel Hill, the AIMS Lab gave four presentations including one podium and three poster presentations. Dr. Powell gave a podium presentation entitled “Older adult runners exhibit grater vertical stiffness

and smaller dynamic joint stiffness compared to young runners”.

Poster presentations included “Immediate and five-day

effect of atlanto-axial high velocity thrust manipulation of peak systeolic blood flow velocity of the vertebral artery” (Michael Mize), “Advancing age is associated with reduced ankle and knee joint powers during level running” (Rachel Plummer) and “Barefoot running does not change ankle and knee joint stiffness values” (Klarie Ake).

AIMS Laboratory student researcher Rachel Plummer (SPT) presents her research investigating alterations in running biomechanics associated with advancing age. Rachel is a second-year Doctor of Physical Therapy student (Class of 2016).

Campbell University Interprofessional Research Event The IPE Research Event is intended to bring together student and faculty researchers within the Health Professions programs at Campbell University. In the Spring of 2015, the IPE Research Event was held in Levine Hall of Medical Sciences. The AIMS Laboratory had two student researchers present their work at the IPE Research Event including Rachel Plummer and Michael Mize. Rachel Plummer presented “Advancing

age is associated with reduced ankle and knee joint powers during level running” while Michael Mize presented “Immediate and five-day effect of atlanto-axxial high velocity thrust manipulation of peak systolic blood flow velocity of the vertebral artery”. These AIMS Lab student researchers received first and second prize, respectively, in their category.
