Wearable sensors reveal hidden body changes during nerve stimulation for CRPS pain

This study looked at 24 people with Complex Regional Pain Syndrome (CRPS) type I in their legs who already use a device that stimulates nerves near the spine (dorsal root ganglion stimulation) to control pain. Researchers used special wearable sensors to track things like heart rate, breathing, sleep, and activity while the device was on and off. The goal was to see if the device affects more than just pain, helping doctors better understand and manage the condition.
