The School of Health Professions department of physical therapy is conducting a research study on muscle development in the legs of children. Strength test will be performed, such as jumping and running, and bone density will be tested through ultrasound. All testing is free. Participants will be compensated up to $50, and parking will be covered. If your child can walk or run without the aid of an assistive device and did not suffer a fracture in the past year, your child may qualify. The total time commitment is approximately 4 hours spread over 2 days separated by a minimum of 5 days.
