NEW GRANT AWARD IEEM
Dr. Benjamin Tseng, Postdoctoral Fellow, at the IEEM was awarded an American Heart Southwest Association Postdoctoral Fellowship. Dr. Tseng proposed a study entitled “Exercise Improves Brain Perfusion and Attenuates White Matter Lesions in Ischemic Stroke Survivors – Pilot Study”. His two year project starts in January of 2013.
The goal of this study is to determine if aerobic training can enhance the recovery of motor function in stroke patients in addition to conventional therapy. The top priority after stroke is to regain the use of limbs and independence. Current standard care for stroke rehabilitation relies exclusively on physical therapy to re-learn motor skills. However, very little attention is given to how blood flow in the brain may impact brain recovery, thus affecting the learning of motor movement. Aerobic exercise can improve vascular health and can provide better oxygen supply to the brain in older adults. It is unclear whether the same benefit can be achieved in stroke survivors.
Three questions will be addressed by the study:
1. Is there a difference in brain structure, brain vascular health, and blood supply in stroke patients?
2. What are the beneficial effects of aerobic exercise on motor recovery and brain health in stroke patients?
3. Is there a relationship between the improvement in motor control and blood supply to the brain?
Fifteen patients aged 40-70 years with first time stroke will receive a three month aerobic exercise intervention. Fifteen comparable patient controls will receive stretching exercise. The study will measure brain motor function, vascular health, brain structure, and blood flow before and after the trail to determine which group has a better outcome.
Presentation AHA National Meeting
American Heart Association Presentation
Tuesday November 6th 2012
Dr. Keri Shafer from the IEEM presented at the National AHA meeting results of research entitled “effects of Prolonged Exercise in Patients with Systemic Right Ventricles”. Her associates in the research are Graeme Carrick-Ranson PhD, Sina Rahmani MD, Dean Palmer MS, Kara Boyd MS, Naoki Fujimoto MD, PHD, Sheryl Livingston, RN, M. Beth Brickner MD, Lisa Forbess MD, Benjamin D. Levine, MD
Dr. Shafer explained the scope of the problem and risks of the condition. Adults with congenital heart disease have lower than predicted exercise tolerance. Low peak VO2 with exercise correlates with higher morbidity and mortality. The hypothesis is that patients with systemic right ventricles will be more likely to develop cardiac fatigue after exercise in comparison to those with systemic left ventricles.
IEEM Celebrates 20 Years
On October 5, 2012, the Texas Health Presbyterian Foundation hosted a luncheon to celebrate and honor the achievements of the Institute for Exercise and Environmental Medicine on its 20th anniversary. Guests comprised of donors, faculty, researchers and friends gathered at the Dallas Country Club to recognize the important mission of the IEEM. A mission to explore and define the limits to human functional capacity in health and disease, with the objective of improving the quality of life for human beings of all ages.
