Caregiver Burden and Correlation With Clinical Outcome in Spinal Cord Stimulation for Chronic Neuropathic Pain

Spinal cord stimulation is an effective therapy for chronic neuropathic pain. After careful selection, the satisfaction for the patient is often considerable. The investigators want to investigate the caregiver burden for relatives of patients who are treated with spinal cord stimulation. This will be evaluated by appropriate scores at baseline, during neurostimulator trial and 3,6 and 12 months after implantation. At the same time the patient satisfaction and pain reduction will also be evaluated independently. In this prospective cohort different parameters will be assessed at baseline, trial, 3, 6 and 12 months follow-up for the patient and their caregiver. For the patient this will include Numeric Rating scale (NRS) for leg and back pain, Oswestry Disability Index (ODI), EuroQuality of Life-5 Dimensions score (EQ5D), opiate use and Relation Quality Index (RQI). For the caregiver the Zarit Burden Index (ZBI), Relation Quality Index (RQI) and Modified Caregiver Strain Index (MCSI). With regard to the research questions, subgroup analysis will be performed regarding to age, sex, education, neurostimulation pattern, surgical vs percutaneous lead placement, working status of both patient and caregiver and caregiver relation characteristics.
