UAMS Seeks Stroke Patients for Study on Preventing Falls
LITTLE ROCK — The University of Arkansas for Medical Sciences (UAMS) has expanded its stroke research efforts with a $100,000 federal grant that focuses on helping stroke survivors avoid future injuries due to falls by studying strength and balance.
Funded by the National Institutes of Health (NIH), the two-year pilot study is led by UAMS’ Mark Mennemeier, Ph.D., an associate professor of neurobiology and developmental sciences.
Because alertness appears to play a role in strength and balance perception, Mennemeier will try to identify therapies that can improve alertness. The study will include up to 55 participants – people who have had a stroke affecting one side of the body and people who have not had a stroke but want to participate as a control subject. Potential study participants may call 501-526-7773 to learn more.
The pilot study examines how changes in alertness after stroke influence perception of strength and balance. Falls in the hospital and at home are related in part to misperception of strength and balance. Problems can persist months and years after stroke. The long-term goal of the study is to improve stroke rehabilitation and to prevent injury by treating problems of alertness.
UAMS’ stroke research includes a new telemedicine program that provides life-saving stroke treatment from neurology specialists who can communicate with rural hospitals using real-time two-way video. UAMS also is leading a four-year NIH study that will help determine the best procedure for preventing strokes caused by blocked arteries in the neck: stents or surgical removal of the artery clogging plaque.
Mennemeier’s research compliments these projects by focusing on rehabilitation and recovery. He is preparing for the start of another NIH-funded study later this year that uses an approved medication to treat problems with alertness after stroke.
Stroke affects 700,000 people annually in the United States. As many as half of these patients may have misperception of their arm and leg strength. Up to one third of all stroke patients may fall during or following stroke rehabilitation.
