Rehabilitation and Physiotherapy

Rehabilitation and Physiotherapy works with the body’s capacity to tolerate load, adapt to stimulus and progress between sessions. When the autonomic nervous system (ANS) remains in chronic sympathetic overactivation, that capacity narrows — not because the tissue is weak, but because the system governing recovery is locked in defence mode.

Non-invasive neuromodulation with NESA XSIGNAL® acts directly on the ANS, expanding the patient’s tolerance window so your manual techniques, exercise and progressive loading find the response they deserve. It does not replace your approach: it enhances it.

Treatment

NESA XSIGNAL® modulates the autonomic nervous system (ANS) to support load tolerance, accelerate recovery between sessions, reduce centrally amplified pain and help restore restorative sleep patterns that consolidate motor adaptations.
It may reduce hyperreactivity, improve heart rate variability (a marker of adaptability) and support consolidation of gains between sessions. Patients progress more consistently when the ANS is better regulated.
It integrates into your plan without conflict with any technique. Before high-load sessions, it can be used as autonomic preparation; afterwards, as a recovery protocol. Each NESA session is tailored to the current barrier: pain, sleep, fatigue or tolerance.

Functional objectives

  • Improved tolerance to therapy and loading.
  • More efficient recovery between sessions.
  • Improved pain control and reduced hypersensitivity.
  • Better sleep and more restorative rest.
  • Improved sympathetic/parasympathetic balance.
  • Greater adherence to, and progression within, the treatment plan.

Applications

Common Clinical Presentations

  • Chronic or recurrent pain — Often amplified by central sensitisation. May benefit from addressing both central and peripheral nociceptive processing.
  • Hypersensitivity / central sensitisation — The patient experiences more pain than would be expected from the diagnosis. Local physiotherapy combined with autonomic regulation may support normalisation of pain processing.
  • Fatigue and reduced recovery — Often centrally mediated rather than peripheral. The patient may struggle because energy is directed towards defence rather than repair. Common in post-viral states, overtraining and chronic conditions.
  • Sleep disturbances — Fragmented sleep with reduced restorative depth. Without adequate sleep architecture, exercise adaptations are limited. Physiotherapy combined with improved nocturnal autonomic regulation may support consolidation.
  • Elevated physiological stress / hyperarousal — A high baseline level of arousal. The patient fatigues quickly, recovers slowly and may develop fear of activity. The aim is to reduce baseline arousal.
  • Inflammation and edema.

As Support for Recovery Processes

  • Post-surgical recovery.
  • Return to loading / return to activity.
  • Low exercise tolerance.
  • Inflammation and edema.
  • Support for microcirculation and tissue perfusion.
Beneficios rehabilitación y fisioterapia

Benefits

  • Support for pain control: acute and persistent — Helps reduce nociceptive reactivity and central amplification. Patients may tolerate manual techniques more effectively.
  • Improved tolerance to therapeutic load and exercise — Expands what the patient can tolerate. Supports return to activity and improves the effectiveness of loading programmes.
  • Improved sleep and recovery — Supports more stable sleep architecture, where motor adaptations are consolidated.
  • Support for microcirculation and peripheral vascular function — May contribute to improved tissue oxygenation, greater work capacity and more efficient clearance of metabolites following effort.
  • Support for inflammatory and oedema processes — Helps regulate inflammation so it remains adaptive rather than persistent. Oedema may resolve more efficiently.
  • Complementary, non-invasive and drug-free support — Compatible with exercise, manual therapy, traction, electrotherapy and pharmacological treatment.
  • Individualisable protocols based on symptoms and autonomic profile — Tailored to the patient’s presentation, whether dominated by pain amplification or central fatigue.

“We believe NESA technology will help us in two fundamental aspects: improving sleep and modulating the autonomic nervous system in patients with long COVID.”
“Before, I couldn’t help these people, I did what I could but it didn’t work. With NESA, I have the opportunity to change my patients’ lives, give them a good feeling and a better quality of life.”
“Before, I was in much more pain, and now I have managed not to feel pain in my feet when walking or in many other things.”
“I have been a physiotherapist for 21-22 years, although I was born in Seville, I have been living for 15 years in Granada, where I have the Fisioterapia Bola de Oro clinic. We work in general physiotherapy, especially with musculoskeletal injuries.”
“We have had cases of long COVID that have improved, especially fatigue and that mental fog they talk about.”
“With NESA®, I went from minutes to an hour of deep sleep. I feel more relaxed, sleep better and face the day with more calm. The sessions make me feel good and notice real improvements.”
“After years without improvement with aggressive treatments, a patient found real relief with NESA, without pain. She came back because the results exceeded her expectations.”
“With NESA, changes were already noticeable from the first session: ‘I sleep better’, ‘I’m in less pain’, and I also perceived improvements in mobility and tissue.”
“After 15 to 18 sessions, I began to notice that my sleep had changed; it was deeper, which released a lot of tension and helped me perform better.”
“Discovering NESA has been very important to me because it calms me a lot, I sleep better, I’m calmer, my nervous problems are more relaxed, my mouth and my deviations are calmer, I don’t tremble as much.”
“With NESA®, I improved after surgery, regulated sleep and stopped medication. In a few sessions, I reduced pain, anxiety and anguish. It has been a very positive experience that I highly recommend.”
“After the 4th or 5th session with NESA I felt my mind clearer, more energy and the improvement has been maintained.”
“What we have worked on most with NESA is sleep, and we have achieved significant improvements in patients with sleep alterations.”
“The first night I tried NESA I slept like I hadn’t slept in a long time. It was spectacular.”
“Many patients recognize that it has changed their way of sleeping, improving their rest and making pain no longer so important.”
“Patients with sleep and anxiety problems, like those who couldn’t sleep a full night, are resting much better. This positively impacts their daily life, improving their general well-being.”
“Being the first nervous system rehabilitation unit in Bilbao… implies a reference center in this.”
“Treatment with Nesa helps significantly reduce pain in patients, which facilitates their rehabilitation.”
“The NESA equipment caught my attention because it’s non-invasive neuromodulation, something that helps people without having to be invasive.”
“By improving rest, patients notice a change in their mood and energy, and it is often their family members who highlight the improvement in their emotional well-being.”
A specialized course addresses the application of Nesa in urogynecological disorders in men, women and children. This effort is part of the company’s commitment to ensure that its technology is scientifically validated before being widely implemented in the clinic.
“The more therapeutic options we have to offer the patient, the better… technologies that are less invasive can be more suitable for them.”
“NESA has proven to be effective in addressing chronic pain of years of evolution that conventional treatment was not achieving. This is especially relevant in cases where patients have postoperative limitations and manage to perform exercises that were previously impossible for them.”
“I would highlight NESA’s compatibility and complement with all types of therapy. It fits well with any treatment, especially in chronic pain and sleep problems.”
“With this technology, the patient not only improves the pathology for which they came, such as specific pain, but also observes a more global improvement in aspects such as fatigue and sleep, even in things they weren’t aware of.”
“I have decided to incorporate NESA in my practice to have more tools that allow me to help my patients, especially those with autonomic nervous system problems, stress, chronic pain and sleep alterations.”
“We had a case of a patient of about 40 years with chronic lumbar and cervical pain, and with a few sessions he began to improve notably, feeling more comfortable. The speed with which the effects are seen is something that really stands out in our practice.”
One of the most notable cases was that of an 80-year-old patient with spinal canal stenosis, whom no doctor wanted to operate on. After six sessions, the patient arrived with a smile, saying he could now leave home and walk with quality of life.
“Being a non-invasive technology, NESA is suitable for patients who do not tolerate other techniques, such as those that include needles, offering benefits without causing aversion or discomfort.”
“The fact that NESA is non-invasive and painless equipment helps a lot for patients to opt for this type of treatment, especially those reluctant to needles or invasive procedures.”
“NESA technology, based on bioelectricity, has been an essential tool in our center, complementing our manual therapy and physiotherapy protocols. It allows us to act at the micro and cellular level, which helps tissues recover their physiology.”
“I have been with chronic pain for years, and after using NESA, I noticed an improvement in sleep quality, pain and quality of life in just two or three sessions.”
“NESA is ideal for patients reluctant to needles or invasive treatments. Its integration with other therapies allows a multidisciplinary approach, achieving better results for patients.”
“After a disabling injury in the groin, Pascual avoided the operating room thanks to NESA®. In a few sessions he recovered mobility, returned to exercising and resumed his normal life. Today he recommends the treatment for having given him back well-being.”
“The autonomic nervous system has been quite a discovery for me. I noticed that I was missing tools in my practice and NESA has been the solution I needed.”
“I think NESA enhances the manual treatment we perform, improving the results we obtain through osteopathic and manual techniques, especially in the autonomic nervous system, a key area in physiotherapy.”
I myself suffered insomnia for 10-12 years, and after using NESA, I have noticed that I wake up with more desire and energy, and increasingly more nights in which I sleep well consecutively.
“I like to look for new ways to integrate treatments, not focus only on one thing, but create a breadth of treatments so that people can come for different reasons.”
“The autonomic nervous system is something that physiotherapists have never been able to treat directly. NESA allows us a more integrative approach, especially in topics like sleep, which is crucial for recovery and cellular tissue regeneration.”
“A colleague of mine, a physiotherapist, had migraine problems and in a very short time with NESA she has managed for them to subside. She has been without migraines for a long time and had always suffered from them.”
“We have opened up to patients with fibromyalgia and sleep disorders. Before we didn’t have so many patients of this type at the clinic, but with NESA technology, we have seen significant improvements in their quality of life.”
“NESA technology is a great help, especially in patients with anxiety, depression, sleep disorders, mood disorders or with traumatic backgrounds. It is a tremendous entry door that allows resources to later do deeper work.”
“Patients who had spent months without resting a full night have managed to sleep straight after just six sessions with NESA.”
“The nervous system, both voluntary and autonomic, is the soul mater of our body. When it fails, multiple problems are triggered that are difficult to reverse, the autonomic system being especially complex but essential for the correct functioning of the body.”
“Having a NESA device in a hospital would be very important because it would greatly reduce waiting lists, prevent surgeries that wouldn’t be necessary, and reduce the toxicity of medications in patients.”
“Patients don’t usually come in for sleep problems, but it does come associated with the conditions they have. So it’s true that it’s one of the first things in which I find improvement.”
“I’ve treated a diabetic neuropathy with very intense pain in the legs and cramps, and with NESA the sleep problems have disappeared completely, which has been a great relief for the patient.”
“The novelty of the NESA equipment allows us to deal with pathologies that at a clinical level were escaping our hands, covering a wide variety of pathologies.”
“Since I use NESA, I have improved my quality of life: I sleep better, I manage pain and I can enjoy more time with my son. That it is available in public hospitals is a great advance to avoid surgeries and private treatments.”
“NESA has opened doors to a new world of possibilities, especially in cases where the improvement of sleep quality or urinary incontinence was difficult to address effectively. This technology allows us to help people even more.”
All opinions
The impact of ANS regulation in rehabilitation and physiotherapy
When autonomic regulation is integrated into practice, changes become visible week by week: less spontaneous pain, better sleep, greater load tolerance and faster recovery. A stable ANS allows your physiotherapy to be more effective. In rehabilitation, this translates into:
A regulated ANS increases what the patient can tolerate. Loads that previously triggered reactive pain may become manageable. Functional gains consolidate more effectively because the body is not operating in a constant defensive state. Progression becomes consistent rather than erratic.

Pain observed in clinical practice is not only mechanical; it also reflects sympathetic overactivation. Each physiotherapy session may gradually reduce sympathetic tone and increase parasympathetic activity. NESA may support this shift. The patient not only experiences less pain, but also perceives less threat within the body.

This is where much of the adaptation takes place: motor consolidation, protein synthesis, collagen repair and regulation of inflammation. A patient with fragmented sleep rarely progresses in a linear way. Daytime physiotherapy combined with stable nocturnal sleep rhythms supported by autonomic regulation may contribute to more consistent recovery.

Better perfusion = better oxygenation during effort = greater endurance = lower lactate accumulation = improved recovery. A patient with chronic vasoconstriction will never reach their full load potential. Restoring vasomotor function is like removing the engine’s RPM limiter.

NESA does not replace what you already do well. Your clinical toolkit remains central.
NESA adds a regulatory layer: it helps the autonomic nervous system become more receptive to intervention rather than defensive against it. A better-regulated patient responds more effectively to therapy, progresses more visibly and is more likely to stay engaged.
