The Neurophysiology of Movement Lab is looking for participants 60-plus-years-old to train lower-body muscles and test changes in standing balance. Participation involves 11 visits (two 2-hour sessions, nine 40-minute sessions) over 3-5 weeks. After their final session, participants will receive $150. Volunteers should be free of any walking impairments and be able to stand independently. If interested, please contact Joey Carzoli at joseph.carzoli@colorado.edu or 904-477-8678.
