"Care-Quip" 4 wheely walkers with stoppers at the back wheels were especially designed for patients with PD.Hence the patient only has to lean on the frame to slow it down.The handbrake version requires dual activity which causes an increase in the apraxic features of PD gait thus reducing gait safety.Thus the CQ frame with stoppers produces a safe reciprocal gait.If necessary the back wheels can be removed for further safety.The frame also has a seat and basket.It can be purchased from Linds Rehabilitation (Aust) for approx. $210.00.
