Wearable Cueing Devices in PD
Author(s):
An expert neurologist discusses sensory-based wearable devices used to control PD symptoms, commenting on challenges with these devices.
This is a video synopsis/summary of a panel discussion involving Zoltan Mari, MD.
The speaker delves into the realm of tremor-helping devices, which patients often inquire about due to their potential to alleviate symptoms associated with Parkinson's disease and essential tremor. One such device is the CUE1, originating from the UK, and although widely used there, it awaits FDA approval in the United States pending a prospective study, which the speaker is actively involved in organizing. The CUE1 aims to address not only tremor but also other motor symptoms like bradykinesia and freezing of gait through vibrotactile stimulation on the chest, akin to the mechanism of action seen in deep brain stimulation.
Another device, the Cala kIQ bracelets, utilizes accelerometers to identify tremor and deliver gentle electrical stimulation to disrupt tremor episodes. Various other sensory-based technologies, including sound, transcranial direct current stimulation, and visual interventions, also target motor symptoms through disruption of sensory inputs to the brainstem.
However, the speaker highlights several challenges facing these technologies. Firstly, conducting well-controlled prospective studies poses difficulties due to the lack of clear placebo solutions. Secondly, commercialization often precedes scientific validation, leading to hesitancy within the movement disorder specialist community regarding the efficacy and appropriate patient selection for these devices.
In conclusion, while tremor-helping devices offer potential benefits, rigorous scientific validation and careful patient selection are essential to ensure their efficacy and appropriate use in clinical practice. Addressing these challenges will be crucial in harnessing the full potential of these technologies for improving the quality of life for individuals with Parkinson's disease and essential tremor.
