Researchers tracking real-world function after subthalamic nucleus deep brain stimulation for Parkinson’s disease found that continuous wearable data captured post-surgical sleep and readiness improvements not reflected in standard clinic activity scores, offering new insight into how consumer smart rings complement traditional patient evaluations.
Monitoring movement disorders outside the clinic has taken on new technical dimensions as researchers report a single-patient case of a 68-year-old man with PD who continuously wore an Oura Ring before and after STN DBS. Consumer-grade wearable devices present a scalable, low-burden means of longitudinal monitoring outside the clinic. Proprietary composite “Activity”, “Readiness”, and “Sleep” scores were analysed descriptively across predefined 60-day pre- and post-DBS periods, excluding the immediate perioperative period. Longer-term trends were assessed over 12 months alongside clinical outcomes.
Northwestern Medicine Neuromodulation and Functional Neurosurgery Program
Subthalamic nucleus deep brain stimulation is a well-established therapy for Parkinson’s disease, but conventional follow-up may miss postoperative fluctuations. Northwestern Medicine is a premier destination for the treatment of movement disorders, and offers deep brain stimulation as a treatment option for patients with Parkinson’s disease, essential tremor and dystonia. The Neuromodulation and Functional Neurosurgery Program specialists collaborate in integrated teams to provide patients with a comprehensive multidisciplinary approach patient care. Deep brain stimulation delivers high frequency electrical stimulation to precise areas of the brain, thereby reorganizing the abnormal signals that result in the symptoms caused by the illness.
Deep brain stimulation (DBS) delivers high-frequency electrical stimulation to precise areas of the brain to block the faulty signals that cause tremors and other movement symptoms. During the surgical procedure, an electrode is placed inside the brain, which is connected to a very small neurostimulator (electrical generator) implanted in the chest or abdomen. Electric current is then delivered from the neurostimulator through the electrode to the targeted area of brain tissue, to block the faulty signals that cause the symptoms. This treatment can be effective in treating tremors, stiffness, walking difficulties, slowed movement and extra movements.
DBS should be considered when symptoms are progressing and becoming more difficult to manage, and when medications do not adequately control symptoms. Medications meant to control symptoms may result in side effects such as dyskinesias (involuntary extra movements), psychiatric problems or other complications. Motor fluctuations and unreliable responses to medications can interfere with quality of life.
Divergence Between Clinic Scores and Free-Living Activity
Conventional postoperative follow-up typically relies on intermittent clinical evaluations. Early post-DBS, “Sleep Score” improved from 45.0 to 53.5 and Readiness Score
from 67.5 to 71.0, while “Activity Score” and daily step count remained stable despite improvement in the Movement Disorder Society-Unified Parkinson’s Disease Rating Scale Part III score.”
Multidisciplinary Evaluation and Target Selection
Patient care requires a multi-disciplinary team including neurologists with specialized training in movement disorders, functional neurosurgeons, neurophysiologists, DBS nursing specialists, neuropsychologists, social workers and rehabilitative therapists. In the case of Parkinson’s disease, two brain regions have been identified where DBS is appropriate: the subthalamic nucleus (STN) and the internal segment of the globus pallidus (GPi). In essential tremor, the ventral intermediate nucleus (Vim) of the thalamus is the optimal target. In dystonia, the preferred target is the GPi.
