Overall, 83% of patients indicated they were willing to recommend PNS to a friend or family member, 74.4% reported overall satisfaction, and the average treatment satisfaction score was 7.63 on an 11-point scale, which the researchers called “remarkable.”
In descending order, the reasons for patient dissatisfaction were the cost of the procedure, device malfunction, and unmet expectations. However, the researchers concluded that PNS can offer long-term benefits for patients with intractable headaches, and should be considered a viable treatment option.
