Bethesda, MD - Hanger Orthopedic Group, Inc. announced today an agreement under which Hanger's wholly-owned subsidiary Innovative Neurotronics, Inc. (IN, Inc.) has granted Teijin Pharma Limited exclusive rights to develop and commercialize IN, Inc.'s initial product offering, the WalkAide(R) System, in Japan. Teijin Pharma Limited is a wholly owned subsidiary of Teijin Limited, a multinational corporate enterprise headquartered in Osaka, Japan. The WalkAide System is a technology that employs functional electrical stimulation to combat lower limb neuromuscular paralysis.

"This agreement is a significant milestone in IN, Inc.'s strategy to extend the adoption of its WalkAide System technology," IN, Inc. President Jeff Martin said. "We are delighted that one of Japan's leading healthcare companies will be working with us to make the WalkAide System available to the many thousands of people in Japan who can benefit from this advanced technological solution to neuromuscular impairment due to stroke, partial spinal cord injury, and traumatic brain injury."

"The consummation of this partnership is further validation of our technology and is a major step towards developing effective global distribution channels for our solution," added Ivan Sabel, Chairman and CEO of Hanger Orthopedic Group, Inc.

Under the terms of the agreement, Teijin Pharma Limited will be responsible for achieving regulatory approval to permit the WalkAide System to be marketed in Japan. It will also be responsible for attaining public reimbursement for the WalkAide System in Japan. Cleared by the U.S. Food and Drug Association in September 2005 and made available in the United States in May 2006, the WalkAide System achieved ISO 13485:2003 and ISO 9001:2000 certification from BSI, Inc. in October 2006, a requirement to obtain marketing approvals in Japan.

The WalkAide System employs functional electrical stimulation to treat a form of paralysis known as "foot drop" due to stroke, spinal cord injury, traumatic brain injury, and other pathologies such as multiple sclerosis and cerebral palsy. By applying low level electrical currents directly to a motor nerve in the leg, the portable WalkAide instructs the muscle to flex the foot so the patient can walk more normally.

A study published in the September 2006 issue of the peer-reviewed journal Neurorehabilitation and Neural Repair suggests the WalkAide can reveal hidden potential for additional patient recovery and mobility. The walking speed of patients wearing the WalkAide increased by 15% after three months. With continued usage, patients' walking speed increased by 32% after six months and by nearly 50% after twelve months. The study also showed the number of steps taken per day by WalkAide users increased significantly over the year.
