Abdominopelvic Treatments

Overactive bladder, chronic pelvic pain and post-surgical pelvic dysfunction share a common denominator: autonomic nervous system (ANS) dysregulation. The hypogastric and sacral plexuses (S2–S4) respond directly to ANS state. When sympathetic activation predominates, the bladder becomes irritable, pain persists and recovery slows.

Non-invasive neuromodulation with NESA XSIGNAL® targets the sacral and lumbar segments involved in continence, pain and visceral function. It does not replace your manual or functional approaches: it enhances 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.

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 Abdominopelvic Treatments, the protocols act specifically on the sacral and lumbar segments that control urinary continence, chronic pelvic pain and visceral function.

Testimonials

“Especially in patients with pain, anxious patients, and those with overactive bladder, we are absolutely clear that NESA will significantly help us in their treatment.”

“From the very first day with NESA I noticed a change. I slept deeply, as if a switch had been turned off. The abdominal inflammation and digestion also improved a lot.”

“NESA has made it possible to provide a response to patients with endometriosis and chronic pelvic pain who were in therapeutic limbo, improving symptoms such as generalized pain, fatigue, insomnia and lack of concentration.”

“NESA® reduced the hyperactivity of the nervous system, improving chronic pain, fatigue and headaches. It was a before and after for the patient and her family.”

“Francisco came with chronic pelvic pain, anxiety and difficulty sleeping. With just 10 sessions of NESA® and physiotherapy, he reduced pain, improved sleep and recovered quality of life.”

“NESA is a non-invasive therapy with great potential in symptoms such as pain, fibromyalgia and migraines. If it works, we have to know it, accept it and share its benefits.”

“In menopause, the patient presented insomnia, dyspareunia and urinary frequency. With NESA® and combined therapy, sleep improved, symptoms reduced and she recovered confidence and well-being.”

“Cristina suffered from dysautonomia and a constant urinary urge. With NESA®, she significantly reduced symptoms and went from going to the bathroom every 10 minutes to enjoying full afternoons away from home.”

“With NESA®, Lucía improved sleep, muscle relaxation and digestive discomfort. The treatment reduced chronic pain and progressively improved her quality of life.”

“Therapy with NESA® improved Belén’s sleep, reduced awakenings and bladder hyperactivity. It alleviated postoperative symptoms and, together with manual therapy, improved her digestive and visceral problems.”

“Ana arrived with extreme pelvic pain that affected her entire life. After 10 sessions of NESA®, she reduced stress, anxiety and pain, and now lives normally and with confidence in her evolution.”

“NESA notably improves sleep in patients with pelvic pain or urinary urgency, enhancing concentration, memory and well-being with a comprehensive and cost-effective approach.”

At only 19 years old, she came with chronic pelvic pain, bladder pain syndrome and vulvodynia, which severely affected her quality of life. After 10 sessions with NESA®, physiotherapy and personalized exercise, the pain decreased, she reduced urinary frequency, returned to playing sports and recovered her social life and confidence.

“What has fascinated me about NESA technology in view of the profile of patients I attend in consultation is how effective it is being painless.”

“It catches my attention a lot that it’s not invasive, that it’s not painful, and that it’s giving good results. Obviously, you have to know it well.”

“In this case NESA is non-invasive, painless, barely perceptible by the patient. What happens is that they do feel the results.”

“The case that has surprised me most was a patient who had to go to the bathroom every 5 minutes. Today she has a totally normal life, can even go up to 5 hours without going to the bathroom.”

“The autonomic nervous system regulates any body function, and working with it is very important. NESA has helped open the range of treatment possibilities in my clinic, since I felt a bit limited with only manual therapy.”

“The virtue I would highlight most about NESA would be its approach to so many pathologies it covers, from pelvic floor pathologies to others that can be treated by psychologists, such as stress, anxiety and depression.”

“Since we have the NESA machine, we have observed a greater flow of patients using it both by our recommendation and coming from outside. Although patients already improved with treatment before, now the improvement is faster.”

“We decided to trust NESA technology to be able to treat the patient globally, especially those with long-evolution pathologies and involvement of the autonomic nervous system. This is what is worked on most with NESA.”

“Being able to work with NESA is an opportunity for both physiotherapists and patients, since it allows improving pathologies that with our hands alone we cannot cover. It is very beneficial for patients’ quality of life, especially in cases of sleep quality and anxiety.”

“Introducing something that really improves them is fundamental, it is a treasure to be able to achieve that.”

“The truth is that in this aspect patients have improved quite a bit and we, well, it is something that since we have it we use it.”

“I have been absolutely impressed with the possibilities that NESA offers, the ability to dialogue with our autonomic nervous system and to be able to influence modulation between sympathetic and parasympathetic.”

“If we balance the autonomic system, the sympathetic with the parasympathetic, we put it in balance, it seems that everything improves at the emotional and physical level.”

“When I saw this technology about a year ago, I immediately shared it with my colleagues at the hospital. I told the head of service who had already heard about it and it immediately interested us. It’s a new thing we have to try and I think it’s going quite well.”

“We have started doing the pilot with NESA… one of my motivations to move forward with this project was that I saw they were patients whose quality of life was quite affected.”

“The treatment has improved sleep and tranquility of patients, even in complex cases with chronic pain, positively impacting their quality of life and family environment.”

“After 12 sessions with NESA, my patient sleeps very well, performs activities she could not before and has even improved motor functions, showing great satisfaction with the treatment.”

“NESA technology little by little you realize it gives you that point of work on the autonomic nervous system, that you as a physio, with all kinds of therapies, you will never reach.”

When specific work on the autonomic nervous system is incorporated, the effect is often systemic: reduced physiological “noise”, more consistent recovery and improved adaptive capacity. In abdominopelvic 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.
