Movement and drainage in a natural rhythm.
NESA supports lymphatic drainage through non-invasive regulation of the autonomic nervous system.
Information for healthcare professionals
Do you recognise yourself?
Swelling, heaviness and slow drainage
Like a blocked return pipe — the water won’t drain. In oedema the autonomic tone regulates the vessels; with high “gas” venous return slows.

Mechanism, indications, protocols and clinical data for implementing NESA.
Microcurrents through the wrists and ankles — the whole autonomic axis at once.
A complement to manual drainage.
Lymphatic and vascular transport are substantially influenced by the ANS: the sympathetic system regulates vascular tone and microcirculation. NESA is used in parallel with manual lymphatic drainage — the lead electrode follows the physiological outflow path, distal→proximal, matching the direction of the manual technique.
Clinical fields: lymphoedema, synchronous with manual drainage (I3 — P7 lasting as long as the manual session; electrode moved distal→proximal along drainage zones) and upper-limb lymphoedema after mastectomy (G1 — 20–30 baseline sessions + maintenance, min. 3×/week; with extensive lymphadenectomy, more modest expectations, transparently communicated). Three phases: central (P1, C6–C7) → metameric (L3) → focal along the zones. 60-min session, LOW; no HIGH in the lymphoedema protocols.
For lymphological indications we build on NESA's general ANS evidence. Application is mechanism-based — autonomic regulation of microcirculation and vascular tone alongside manual drainage. As a general principle (not a lymphological endpoint):
carotid vasodilation (cross-sectional area) — Mínguez-Esteban, Front Neurosci 2025.
HRV (SDNN) and vagal tone (RMSSD).
Limits & safety: NESA is applied after individual medical assessment. Protocols are guidelines; they complement manual drainage. XSIGNAL is a medical device — applied after individual assessment. With an oncological history (common in post-mastectomy lymphoedema), application is by qualified staff within an interdisciplinary plan. Absolute contraindications: pacemaker and pregnancy.

At the core: programmes P1–P9
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.

Parameters are guides; the therapist adapts them to the patient.
NESA is applied after individual assessment — as part of the overall medical plan.
Absolute contraindications (pacemaker, pregnancy, active electrical implants) follow the device IFU.
Before you invest — the independent assessment.
We map clinical goals, workflows, budget and reimbursement — then recommend the solution that meets the department’s needs, not the easiest to sell.
