Article Synopsis
  • Parkinson's disease increases the risk of falls, which can lead to injuries and a decline in quality of life; therefore, accurate assessment of fall risk is essential for effective care planning.* -
  • Traditional fall risk assessments are subjective and time-consuming, while this study explored a short, sensor-based approach that can predict falls up to 5 years later using data from 104 individuals with PD.* -
  • The Random Forest machine learning classifier showed the best performance, achieving 78% accuracy at 60 months, with important predictors being walking and postural variability; incorporating age data further improved the prediction accuracy.*

Essential tremor (ET) is one of the most common movement disorders in adults. Deep brain stimulation (DBS) of the ventralis intermediate nucleus (VIM) of the thalamus and/or the posterior subthalamic area (PSA) has been shown to provide significant tremor suppression in patients with ET, but with significant inter-patient variability and habituation to the stimulation. Several non-invasive neuromodulation techniques targeting other parts of the central nervous system, including cerebellar, motor cortex, or peripheral nerves, have also been developed for treating ET, but the clinical outcomes remain inconsistent.
