Efficacy of NESA Non-Invasive Neuromodulation in Patients with Post-Traumatic Cervicalgia

Injuries to the cervical spine from in-itinere traffic accidents result in significant healthcare, labor, and indemnity costs. The treatment of potential functional repercussions represents a significant challenge, with symptoms frequently resulting in the prolongation of therapies. The objective of the study was to evaluate the efficacy of the NESA non-invasive neuromodulation in the treatment of cervical spine injuries. The device employs superficial microcurrents to modulate the autonomic nervous system, thereby promoting relaxation, vasodilation, and muscle nutrition. This observational multicenter study was conducted at ACTIVA Mutua’s rehabilitation facilities in Madrid, Barcelona, and Córdoba. 21 patients presenting grade I-II cervical whiplash, as per the Foreman and Croft classification, were evaluated using the Biomek biomechanical analysis system before and after the intervention, which comprised 14 days of NESA neuromodulation with active exercise. Pain and cervical disability questionnaires were administered to assess subjective outcomes. Results demonstrated a reduction in cervical mobility limitations and the onset of pain and disability within 14 days. A statistical analysis of mobility data (initial assessment vs. evolutionary control) revealed an increase in mobility in the four movements: flexion, extension, lateral flexion, and rotation. In relation to the values of the questionnaires, a decrease in cervical pain and disability was observed.
