Impact of Quantitative Assessment of Parkinson's Disease-Associated Symptoms Using Wearable Technology on Treatment Decisions.

We read with interest the report by Santiago et al. [1], demonstrating that clinician decision making regarding the management of motor symptoms of Parkinson’s disease (PD) can be enhanced by home-based, continuous objective measurement. Within the UK National Health Service, we have also been using the Parkinson’s Kinetigraph (PKG) since 2015. Similar to the Santiago cohort, in routine care, physicians target PKG use in patients they believe continuous objective measurement will improve the value of clinical encounters. With support from Parkinson’s UK, we have carried out an evaluation of utility across seven centers from the Parkinson’s Excellence Network, comprising a mix of local services and regional specialist neuroscience centers led by consultant neurologists, geriatricians or Parkinson’s nurse specialists
