The Effect of a Wearable Cueing Device on Freezing of Gait in Parkinson's Disease

The CuePeD trial is an intervention trial measuring the effectiveness of a novel treatment for Freezing of Gait (FOG) in Parkinson's disease (PD). The primary intervention is the use of a wearable cueing device (WCD), which detects and responds to FOG and extinguishes on the resumption of normal walking. It is designed for use in PD patients with FOG, in their home environment where FOG is most severe. Kinematic data will be logged by a memory card in the belt worn device recording FOG, and falls. The device will be used on 3 different settings in a gait laboratory environment, and then for 2 weeks in the patient's own home using the same 3 settings. A battery of psychometric instruments will be administered before and after the trial
