Scientists at the Shiley Center for Orthopedic Research and Education (SCORE) at Scripps Clinic are conducting a study to test a new anti-gravity treadmill used for rehabilitation. They are gathering data from patients with a unique artificial joint called the electronic knee, or e-knee. The prosthesis contains transducers that measure actual forces inside the knee.
"The e-knee is unique in the research community and gives us an unprecedented ability to collect data," said Darryl D'Lima, M.D., Ph.D., laboratory director at SCORE. "Before we created it, information about the amount of force generated in the knee by various activities came from untested mathematical formulas."
SCORE made history in 2004 when Clifford Colwell, M.D., implanted the first e-knee into a patient. Four people now have the prosthesis; all of them are participating in the study, which is led by Colwell and sponsored by rehabilitation device-maker AlterG Anti-Gravity Treadmill.
The treadmill was built with NASA technology and is available at the Scripps Memorial Hospital Encinitas rehabilitation center. Designed to simulate a weightless environment, it uses air pressure to lift the patient and reduce gravitational forces on the lower extremities.
