More possibilities for your patients with spasticity.
Discover a new breakthrough in wearable, near full-body neurostimulation: a drug-free, non-invasive technology designed to enhance patients’ mobility and relieve their spasticity-related pain.
Neurostimulation is a proven approach that has been extensively evaluated in neuromuscular disorders like spasticity (1-6) – a debilitating condition associated with cerebral palsy (CP), multiple sclerosis (MS) and stroke. The Exopulse Mollii Suit takes this trusted technique a groundbreaking step closer to its true potential for people with spasticity.
Targeted neurostimulation tailored to each patient’s unique needs.
Just like you and your clinical team, the Exopulse Mollii Suit provides personalized care for every patient. With 58 embedded electrodes, each controlled by up to 30 settings, you can precisely target stimulation to up to 40 key muscle groups throughout the body – and potentially deliver significant improvement in patients’ mobility and pain symptoms in as little as an hour. (7)
How it works
The Exopulse Mollii Suit uses a proprietary, customizable stimulation pattern to release spastic muscles by reactivating their weakened antagonists, using a technique called reciprocal inhibition.
Unlike most standard spasticity treatments, this combined approach uses the body’s own natural reflex mechanisms to rebalance muscle activity – and may help patients move more freely, safely, and with less pain.
“It’s like I can breathe again.”*
Louisa’s MS-related spasticity was severely limiting her mobility when she discovered the Exopulse Mollii Suit. With near full-body stimulation, she experienced rapid improvement in her gait, balance, and motor function. Now, normal activities of daily living are a part of her day-to-day life once again.
“I can finally give hugs again.” *
When Michele experienced a progression of his dystonic spastic tetraparesis, he and his care circle looked to the Exopulse Mollii Suit to help support his mobility. Today, the Suit continues to help Michele stay active, upbeat, and top performer on his wheelchair rugby team.

With near full-body neurostimulation, better mobility is possible for patients experiencing spasticity related to numerous neurological disorders and injuries. See how the Exopulse Mollii Suit helped improve the mobility of these three unique patients.
With regular use, she trusts her Exopulse Mollii Suit to enable safe, stable ambulation, even on uneven surfaces.
After an hour in the Exopulse Mollii Suit, his performance on the validated Timed Up and Go (TUG) test improves dramatically.
Sixty minutes of stimulation with the Exopulse Mollii Suit gives him better control of both his upper and lower limbs.
Give your patients a chance to move more freely and safely. (6)**
Early clinical results show that patients with CP, MS, and stroke had better balance and reduced their risk of falls after just 60 minutes in the Exopulse Mollii Suit. Regular, every-other-day stimulation helped them maintain their improvement.
Help patients achieve swift, sustained relief from spasticity-related pain. (6)***
In the same preliminary study, an hour in the Exopulse Mollii Suit helped significantly reduce pain symptoms in patients who reported them. Four weeks later, patients who regularly used the Suit experienced continuing reduction in pain.

Indication and usage
The Exopulse Mollii Suit is an assistive medical device for pediatric and adult users with cerebral palsy (CP), multiple sclerosis (MS), stroke or other neurological disorders, who suffer from spastic and tense muscles, weak muscle activation and related pain.
The device is recommended to be used every other day, unless otherwise specified by a healthcare provider, preferably together with physiotherapy, training, or activity.
Do not use the Exopulse Mollii Suit:
If the user has implanted electronic medical devices or equipment which can be disrupted by magnets (e.g., shunts)
Together with electronic life-support equipment or high-frequency operation equipment
Together with EKG-equipment
There is a risk of the Exopulse Mollii Suit disturbing the function of the above-mentioned types of equipment. All incorrect usage is at the user's own risk.
Stimulation should not be applied:
Over swollen, infected, or inflamed areas or skin eruptions (e.g., phlebitis, thrombophlebitis, varicose veins, etc.).
Over the neck or mouth. Severe spasms of the laryngeal and pharyngeal muscles may occur, and the contractions may be strong enough to close the airway or cause difficulty in breathing.
Transthoracically, in that the introduction of electrical current into the heart may cause cardiac arrhythmias.
Do not use the Exopulse Mollii Suit without consulting a doctor in connection with:
Skin disease, rashes, or other skin problems
Another medical device or medical treatment
Usage in connection with the above can expose the user to unnecessary risk and is therefore at the user's own risk. Always consult a doctor.
Reported side effects
A small number of patients have reported mild, transitory side effects typical of electrical stimulation, including:
Minor skin irritation
The Exopulse Mollii Suit should preferably be used in combination with physiotherapy, training, or physical activity. It is not contraindicated for use with most standard therapies, such as BoTN injections or oral pharmaceuticals. It should not be used in combination with implanted medical devices, including an intrathecal baclofen pump.
Always document the patient’s current care regimen before starting stimulation with the Suit and consult the prescribing physician if needed.
Financial coverage for the Suit may vary depending on where your practice is located. For information about coverage in your area, contact your regional Ottobock representative.
Care and maintenance
The Exopulse Mollii Suit garments (not the control unit) are machine-washable up to 25 times at 40°C/104°F. The garments may also be cleaned in a steam cabinet as often as necessary.
The control unit may NOT be placed in a washing machine or steam cabinet. Doing so will void the two-year warranty.
The Exopulse Mollii Suit jacket and pants are constructed from comfortable, breathable, washable synthetic materials. The garments contain no animal products or fibers.
The Exopulse Mollii Suit has been evaluated in several small, independent studies with published outcomes. While these studies provided some directional clinical insights, there were limitations:
Small, heterogeneous patient cohorts
Varied endpoints and evaluation methods
No assessment of immediate clinical impact
These studies and their outcomes should be interpreted carefully in view of these restrictions in their conclusions.

**Based on change in Berg Balance Scale (BBS) score in an open-label study of group-level response to Suit stimulation in patients with CP (adult and pediatric), MS, and stroke. Results of this study were evaluated in 38 patients with impaired balance and an increased fall risk (n=15/15/8 CP/MS/stroke, baseline BBS score < 45). Patients in all cohorts reported significant improvement in BBS score after 60 minutes of stimulation (T1) and after 4 weeks of stimulation every other day (T2).
***Based on change in EQ5D pain levels in an open-label study of group-level response to Suit stimulation in patients with CP (adult and pediatric), MS, and stroke. Change in pain levels was evaluated in a subset of 32 patients who reported spasticity-related pain at baseline (n=10/15/7 CP/MS/stroke, baseline EQ5D pain > 1). Patients in all cohorts reported significant improvement in EQ5D pain score after 60 minutes of stimulation (T1) and after 4 weeks of stimulation every other day (T2).
