Functional Treatments

In functional intimate health, patients often present with symptoms that converge around a common pathway: pelvic pain, insomnia, sexual dysfunction and fatigue are manifestations of autonomic nervous system (ANS) dysregulation. When the ANS is out of balance, pelvic organ function, sleep quality, sexual response and recovery can all be affected in cascade.

Non-invasive neuromodulation with NESA XSIGNAL® helps regulate the central system that coordinates all these processes simultaneously. It does not replace your functional assessment or your interventions: it complements 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.

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 Functional Treatments, the protocols act specifically on the transversal autonomic regulation underlying pelvic pain, sexual dysfunction, insomnia and chronic fatigue.

Testimonials

“It is very minimally invasive. Secondly, we can do it in a doctor’s office. We don’t have to use an operating room, as is the case with other technologies.”

“It is a technology that is not expensive, that can yield very good results, but selecting patients with the characteristic phenotype suggesting an autonomic nervous system dysfunction.”

“There are plenty of patients who require exploring alternative paths, and this is the most promising one.”

“There is a lot of soul in the pelvis… when children are stressed they have stomach aches or urinary problems, and in that sense it would be a good tool because it neuromodulates the entire central nervous system.”

“With NESA®, Bárbara reduced urinary frequency, improved pain and recovered sleep and her autonomy. From the fourth session she noticed more rest and better stress management.”

“Carme, with postpartum overactive bladder, managed to reduce anxiety and lengthen the time between urinations thanks to NESA®. Now she lives with more stability and confidence.”

“The autonomic nervous system is everything; the bladder works thanks to the parasympathetic system, and managing to reorder that balance between the sympathetic and parasympathetic systems is a fascinating world full of possibilities.”

“NESA improves urinary symptoms, sleep and anxiety in a comfortable and non-invasive way, with high patient satisfaction and great projection in urogynecology and functional medicine.”

“From the first sessions I noticed improvements: I sleep all night, without anxiety or interruptions to go to the bathroom. I feel much more rested and relaxed.”

“At GUFFU 2025, NESA emerges as a hope for a holistic and personalized treatment of overactive bladder, with promising results and patients already on a waiting list.”

“Seeing the evolution and happiness of patients, improving their quality of life, is the greatest reward. With NESA, for a few months now, we have observed objective improvements in very desperate patients who recover confidence and social activities thanks to this new technology.”

“NESA acts on the autonomic nervous system and offers rapid responses in different dysfunctions. Its potential in the regenerative area has especially surprised me.”

“NESA offers a non-invasive and accessible alternative to treat conditions such as overactive bladder, insomnia or irritable bowel, encouraging the active participation of the patient and with better tolerance than other methods.”

“With NESA we expand our therapeutic tools to address chronic problems, especially in gynecology, with great expectations after the positive experience of our physiotherapists.”

“NESA is a non-invasive, effective and cost-efficient alternative, ideal for patients who do not respond to conventional treatments, focused on restoring quality of life and well-being.”

“NESA is a non-invasive and comfortable option to treat symptoms related to menopause, such as hot flashes, sleep alterations and urinary urgency, improving quality of life without side effects.”

“NESA brings a modern and non-invasive vision to functional urology, improving vital reflexes and quality of life, with a personalized approach focused on the patient.”

“At Don Benito Villanueva hospital, a pioneer in Spain with this technology, we already see clear benefits in just three months. It is a more economical and effective option, focused on patient well-being.”

“NESA technology has great value because it allows improving the patient without the need to go to the operating room. Being non-invasive, it frees up hospital resources, reduces waiting lists and can be applied by nursing staff, increasing care capacity.”

“This basic treatment significantly improves quality of life, especially in women with incontinence problems. It is painless, accessible free of charge in our health system, and I encourage everyone to consult their doctor to receive this effective help.”

From the first day with NESA I noticed improvement: I stopped going to the bathroom so many times and no longer needed to wear protection. In addition to improving my incontinence, I feel more relaxed, sleep better and live again. I would recommend this treatment to everyone; its arrival at the hospital has been a true opportunity.

“This non-invasive technology improves quality of life without pain, reduces costs and increases healthcare efficiency. As pioneers in Spain, we recommend it for all public hospitals.”

“For example, treating a patient… overactive bladder… I have seen very good results, I have to wait for this to be reproduced with more patients, but in this case it caught my attention that with only two sessions the patient is seeing changes”

“NESA came up and I think it’s one more therapy that should be introduced in all healthcare professionals.”

“The autonomic nervous system is unknown in physiotherapy and its treatment can open a world of possibilities in the treatment of pathologies such as pain, fatigue, depression, overactive bladder, among others.”

“I have worked extensively with pelvic floor pathologies, both female and male, and visceral pathologies. Being able to synthesize in a machine and a device the activation of the autonomic nervous system for the global recovery of the person is fundamental and is the distinctive touch of NESA.”

“I have seen that from menopause there is a lot of difference in women’s sleep quality. Sometimes it’s because of hot flashes, sometimes because the number of sleep hours decreases. There are probably other vital factors that influence this, but there is indeed a decrease in hours and quality of sleep. I think NESA has an important job to do here.”

“It seemed to me an opportunity to address many pathologies and understand the person’s health in an integral way, which ultimately is what is important.”

“I hope we can give a little light to our patients who turn to us to seek a solution to their problems in a non-invasive and effective way.”

“For me the greatest advantage of NESA is that it is a treatment that has absolutely no side effects, that will always create a change effect in the body that can be positive and that is not aggressive, that is not felt, that is easy to apply and that will add to all types of treatments you may consider indicated for that patient.”

“The arrival of NESA at our public hospital offers a painless and non-invasive therapy that significantly improves quality of life, motivating patients with a comfortable and effective treatment that replaces previous invasive methods.”

“NESA therapy, with NESA neuromodulation, adds value and we will have to incorporate it naturally. We look forward to applying it to patients, with the certainty that it will contribute to improving their quality of life.”

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 functional 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.
