Abstract Introduction Chronic neck pain (cNP) is one of the leading causes of disability worldwide, often being refractory to conventional forms of treatment. Various forms of electrical stimulation have been proposed to decrease pain and improve function. Patient-reported outcome measures (PROMs) for treatment of cNP have rarely been published. Methods An independent retrospective statistical analysis of PROMs data for users of H-Wave® device stimulation (HWDS), prospectively collected by the device manufacturer over a 4-year period, was conducted. Final surveys for 34,192 pain management patients were filtered for pain chronicity limited to 3–24 months and device use of 22–365 days, resulting in 11,503 patients with “all diagnoses”; this number was further reduced to 1482 patients with cNP, sprain, or strain. Results Neck pain was reduced by 3.13 points (0–10 pain scale), with significant (≥ 20%) relief in 86.6%. Function/activities of daily living (ADL) improved in 96.19%, while improved work performance was reported in 84.76%. Medication use decreased or stopped in 65.42% and sleep improved in 60.39%. Over 95% reported having expectations met or exceeded, service satisfaction, and confidence in device use, while no adverse events were reported. Subgroup analyses found positive benefit associations with longer duration of device use. Conclusion Near-equivalent outcomes were self-reported by cNP HWDS patients as for (previously published) chronic low back pain (cLBP) patients. HWDS provided effective and safe cNP relief, improvements in function and ADL, along with additional benefits including decreased medication use, better sleep, and improved work performance.
