PD-Watch

Target population: Patients with Parkinson's Disease or Tremor 

Measures:  Tremor, Dyskinesia 

Clinical support:  Monitoring 

Some of the proposed solutions are based on wearable sensors and on the signal processing to evaluate the frequency content in the range in which PD movements typically occur (i.e. usually up to 12 Hz). However, most typical habitual motor activities performed by patients may have a power spectrum (e.g. up to 20 Hz) that overlaps with the range in which physiological movements typically occur. Hence, solely evaluating the frequency content does not usually offer a sensible distinction between movement disorders and normal daily motor activity.

In order to improve this, the PD-Watch has been proposed that evaluates the frequency data content coming from an accelerometer and identifies specific movement patterns that movement disorders are typically associated with (e.g. hand tremors due to PD usually occur between 3 Hz and 7 Hz with a supination–pronation characteristic). With reference to PD-induced hand tremor detection, this tool checks both if the movement frequency falls within the above quoted typical range and if it has a supination–pronation pattern. This reduces the probability of being misled by other physiological or pathological movements occurring at same frequency as PD tremors, but with a movement pattern that differs from the characteristic supination–pronation motion.
