Brief summary

1. Objective and Rationale: The study seeks to evaluate how Dorsal Root Ganglion Stimulation (DRGS) influences autonomic functions in patients suffering from Complex Regional Pain Syndrome type I (CRPS I), offering new metrics beyond pain scores to assess therapeutic efficacy. 2. Innovative Approach: Continuous monitoring of patients using validated, CE-marked biosensors (Corsano Biosensor and Motionwatch8) to collect real-time physiological data during active DRGS therapy and therapy cessation periods. 3. Clinical Impact: Results from this study may improve patient management strategies and refine treatment protocols for individuals living with CRPS I.

Interventions

DEVICEdorsal root ganglion stimulation cessation

Treatment of DRGS will be stopped at home and physiological parameters will be monitored with bio wearables at home. physiological parameters will be monitored during a baseline period, before stopping DRGS. While DRGS is stopped. And during the period while the DRGS is turned back on.

Inclusion criteria

* Patients diagnosed with Complex Regional Pain Syndrome Type I (CRPS I) of the lower limbs. * Currently treated with Dorsal Root Ganglion Stimulation (DRGS). * Patients must experience \> 50% pain relief with DRGS therapy for at least three months. * Willingness and ability to comply with the study requirements, including wearing biosensors, and sharing their physiological parameters.

Exclusion criteria

* Refusal or inability to wear biosensor wearables. * Current pregnancy. * Patients with other significant medical conditions that could affect autonomic function. * Known allergies or intolerance to materials used in biosensors. * Diagnosis of untreated Obstructive Sleep Apnea Syndrome (OSAS). * Ongoing psychiatric disorders

Design outcomes

Primary

MeasureTime frameDescription
Heart Rate1 weekHeart Rate (beats per minute), measured using the Corsano Biosensor 287-2 wearable device (CE-MDR certified)
Heart Rate Variability1 weekHeart Rate Variability (milliseconds), measured using the Corsano Biosensor 287-2 wearable device (CE-MDR certified)
Respiratory Rate1 weekRespiratory Rate (breaths per minute), measured using the Corsano Biosensor 287-2 wearable device (CE-MDR certified)
Blood Pressure1 weekNon-invasive Cuffless Blood Pressure: systolic, mean and diastolic (mmHg), measured using the Corsano Biosensor 287-2 wearable device (CE-MDR certified)
Body Temperature1 weekCore Body Temperature (°C), measured using the Corsano Biosensor 287-2 wearable device (CE-MDR certified)
Oxygen Saturation1 weekOxygen Saturation (SpO2, %), measured using the Corsano Biosensor 287-2 wearable device (CE-MDR certified)
Sleep Quality1 weekSleep quality is measured using the MotionWatch 8 actigraphy device (FDA-cleared, CE-marked). For each night of sleep, the bed times and get-up times are entered (either manually, graphically or automatically) and the software automatically determines the sleep start and end times. The analysis then utilises the night-time movement data (e.g. immobile mins and mobile mins) to determine the quality of sleep and provides a list of key sleep parameters.
Physical Activity1 weekPhysical Activity (activity counts per time frame) is measured using the MotionWatch 8 actigraphy device (FDA-cleared, CE-marked).

Secondary

MeasureTime frameDescription
Pain intensity1 weekPain intensity (patient-reported) will be assessed using the Numeric Rating Scale (NRS; 0 = no pain, 10 = worst possible pain), recorded three times daily.
Sleep quality1 weekSleep quality (patient-reported) will be evaluated with a five-point Likert scale (1 = strongly disagree to 5 = strongly agree) based on specific sleep-related statements.
Patient Global Impression of Improvement1 weekPatient Global Impression of Improvement (PGI-I) will be used to assess overall patient-perceived change, using a seven-point Likert scale (1 = very much improved, 7 = very much worse).
Pain condition-related medication usage1 weekMedication intake will be recorded daily by the participant as a count of analgesic medication dosages taken.
