Abstract
A walking stabilizer equipped to combat the effects of akinesia paradoxica by employing a novel method and device to regulate and actuate a projection instrument which generates a pattern perpendicular to the user's direction of travel. The regulating and actuating device comprises a two pole series switch circuit configuration in tandem with the walking stabilizer's novel dual action braking mechanism. The projection device is only operable when the user concurrently selects its use and when the walker stabilizer is free for movement or in contact with the patient.
