Neurological treatments

Every neurological patient has autonomic dysfunction. It is not a comorbidity: it is a feature of the diseased nervous system. Autonomic neuropathy in diabetes, vegetative dysfunction in Parkinson’s, autonomic lability in epilepsy. HRV predicts neurodegenerative progression better than many motor scales — yet it remains unmeasured in most clinical protocols.

Non-invasive neuromodulation with NESA XSIGNAL® improves autonomic regulation, stabilises sleep, reduces falls and enhances the effect of your neuromodulatory drugs. It does not replace them: it amplifies them.

Treatment

Non-invasive neuromodulation with NESA XSIGNAL® acts directly on the autonomic nervous system, supporting processes that influence pain, tone, inflammation, microcirculation and sleep quality.

By targeting autonomic regulation, it may help reduce hyperreactivity, improve physiological variability and promote more efficient recovery between sessions.

It integrates as a supportive component within the treatment plan, without interfering with other interventions, and can be tailored to the patient’s profile: symptoms, sleep, pain, stress levels and load tolerance.

Functional objectives

  • Improved pain control and reduced hypersensitivity.
  • Better sleep and more restorative rest.
  • More efficient recovery between sessions.
  • Improved sympathetic/parasympathetic balance.

Applications

Common Clinical Presentations

  • Neuropathic pain.
  • Sleep disorders.
  • Fatigue and reduced recovery capacity.
  • Autonomic dysregulation (sympathetic/parasympathetic imbalance).
  • Headaches and migraine.

As Support for Recovery Processes

  • Post-surgical recovery.
  • Support for microcirculation and tissue perfusion.
  • Return to loading / return to activity.
  • Low exercise tolerance.

Benefits

  • Support for pain management: acute and persistent.
  • Improved sleep and recovery.
  • Reduced hyperreactivity and enhanced stress regulation.
  • Better functional capacity and participation in therapy.
  • Complementary, non-invasive and drug-free support.
  • Individualised protocols tailored to symptoms and autonomic profile.

Introducing NESA XSIGNAL®

NESA XSIGNAL® is a non-invasive neuromodulation system that applies very low-intensity microcurrents through electrodes, with protocols oriented towards regulation of the autonomic nervous system. It is designed to integrate into clinical practice as part of the multimodal approach.

In Neurological Treatments, the protocols act specifically on the autonomic dysfunction associated with neurodegenerative pathology, epilepsy, multiple sclerosis and diabetic neuropathy.

Testimonials

“I feel that when they see the benefits that they have already seen in my consultation but they will see us more completely, they will feel very happy and so will I.”
“I think a non-invasive method is interesting especially for patient safety and ease of use that can be extended worldwide. If we have the parasympathetic neuromodulator nervous system, we can achieve control not only in sleep but also, for example, at the heart level.”
“Non-invasive neuromodulation is being a key tool when it comes to providing benefit and adequate treatment to all these patients. This translates not into the cure of these pathologies, but into mitigating and greatly decreasing the intensity of these symptoms. This finally translates into a considerable increase in these patients’ quality of life.”
“The patient with post-COVID-19 vaccine neuropathic pain experienced notable improvement after 15 sessions of NESA® neuromodulation, with decreased joint pain, increased energy and reduced fatigue, achieving significant recovery although she still attends occasional follow-up sessions.”
“After starting treatment with NESA, I stopped using crutches and noticed a great improvement in my mobility. Now I walk daily with my wife, which I couldn’t do before, and I experienced a very strong change in my quality of life.”
“It has been the little push that I needed to finish my recovery. NESA, added to the two therapies I was doing, has allowed me to recover. I haven’t had any syncope, which were repeated with quite continuity. I’m very happy and noticing improvement.”
“With NESA, by influencing the nervous system, it is a very good tool that allows us to reach deep levels that with other techniques or with the hands we cannot reach.”
“NESA has proven useful in cases of anxiety and depression associated with chronic pathologies, helping patients improve their emotional and physical balance.”
The impact of regulating the ANS in neurological treatments
When specific work on the autonomic nervous system is incorporated, the effect is usually transversal: less physiological “noise”, better recovery and greater adaptive capacity.

In neurological treatments, this may translate into:
Supporting autonomic balance may expand the patient’s adaptive capacity, allowing local interventions such as manual therapy, exercise or procedures to be better tolerated and more consistent over time.
