Non-invasive modulation of autonomic control in support of respiratory function and recovery.
Breathing that tightens under stress
Like airways that narrow with agitation and open when the body calms. The ANS regulates bronchial calibre; with high “gas” the airways become hyper-reactive.
Self-assessment, not self-diagnosis — discuss with a professional.
Support for parasympathetic tone.
Aid in recovery and load tolerance.
Better sleep quality.
Mechanism, indications, protocols and clinical data for implementing NESA.
Microcurrents through the wrists and ankles — the whole autonomic axis at once.
The vagus nerve carries afferent signals from the airways and modulates cough-reflex sensitivity. A disturbed autonomic balance with sympathetic dominance can shift the threshold and amplify functional complaints such as nervous or irritant cough. NESA addresses not the lung-tissue structure but the processing and regulation of reactivity; HRV serves as an objective marker of autonomic adaptability.
Clinical fields: nervous cough (H3 — min. 20 sessions; P1, P2, P7, P8; electrode: sternum, C6–C7, nasion) and symptom management in pulmonary fibrosis (H4 — up to 20 sessions, palliative, for dry cough from parenchymal remodeling, not for COPD/productive cough; induction 3–4×/week, then maintenance up to 1×/month). Three phases: central → metameric → focal. 60-min session, LOW; no HIGH in the pulmonary protocols.
For the pulmonary indications (nervous cough, fibrosis) our base has no field-specific RCTs. Application is mechanism-based — aiming at improved adaptive response, not a change in structural lung status. As proof of principle:
HRV (SDNN) and vagal tone (RMSSD).
in fibrosis, application is symptomatic and palliative; sustained maintenance is needed for any effect.
Limits & safety: NESA promises no cure and does not change structural lung status. Protocols are guidelines, not prescriptions; they complement — not replace — pulmonary diagnostics and therapy. XSIGNAL is a medical device, not for everyone. In progressive lung disease, use is coordinated with the treating team. Absolute contraindications: pacemaker and pregnancy.

Every protocol in this field combines the reference programmes P1–P9 — general homeostasis, body levels, ANS/CNS and targeted nerves — according to the clinical goal.
See programmes P1–P9 →Parameters are guides; the therapist adapts them to the patient.
NESA is not suitable for every patient and promises no cure.
Absolute contraindications (pacemaker, pregnancy, active implants) follow the device IFU.
