About Mollii

What is Mollii?


Mollii is a suit consisting of a pair of trousers, a jacket and a detachable control unit. The Mollii garments includes 58 imbedded electrodes, positioned to stimulate 40 key muscles in the body. Through a low frequency electro-stimulation, Mollii relaxes spastic, tense and aching muscles safely and simply. Programmed after each person’s needs, Mollii prevents and counteracts different forms of muscle shortening and rigidity, helps the user regain control over muscular tension, and reduces pain related to spasticity. In addition, through electro-stimulation settings, Mollii may facilitate the activation of muscles, and thereby may facilitate muscle contractions, which in turn enable movements.

Who uses Mollii?


Mollii is used by people who suffer from spasticity and spasticity-related pain, which is typically found in people with cerebral palsy, stroke, multiple sclerosis, spinal cord injury, acquired brain damages and other neurological injuries that result from or create motor disabilities, and generally induce pain. Mollii is used both by adults and children; and is available in men and women sizes starting from 104 cm. up to XXXL.

Mollii can be used in both a home and clinic environment; and is simple to use for all ages. Users dress-up with a Mollii the same way they would with an ordinary garment. There is a button for on/off and a button for play/ pause. A single push of the button starts the muscle stimulation, which proceeds automatically for 60 minutes, and has a lasting positive effect for up to 48 hours.”

How does it work?


Mollii stimulates the antagonist to the spastic muscle. If the bicep is spastic, the tricep is stimulated, which in turn makes the bicep relaxed. Relaxing the muscle enables active movements and a gradual improvement in function, while the body keeps this positive effect for up to 48 hours. The physiological mechanism is called reciprocal inhibition.

Mollii also reduces pain related to spasticity, both through the reciprocal inhibition, and via the gate control theory of pain, which asserts that non-painful input such as the electric stimulation of skin-nerves closes the nerve-gates to painful input, which prevents pain sensation from traveling to the central nervous system.

Moreover, Mollii may facilitate the sub-threshold stimulation of a muscle by preparing the muscle for contraction before generating a shortening of the muscle, thereby reducing the nerve signal-strength required by the patient to actually generate a muscle contraction.

It is a safe and simple assistive device that can increase quality of life and help recover faster motor functions. The device is used for one hour every second day. For optimum effect, Mollii should be used together with physiotherapy, training, activity and movement. The positive effect is individual and remains for up to 48 hours.

Frequently asked questions

1Who is Mollii for?
Mollii is an assistive device for people with spasticity and other forms of motor impairment due to cerebral palsy, stroke, brain damage, spinal cord injury or other neurological injuries. Molli can also be used to alleviate spasticity related pain.
2How does the Mollii suit work?
Molli is a functional garment that consists of a pair of trousers, a jacket and a detachable control unit which sends electrical signals to the user via electrodes on the inside of the garment. The suit has 58 electrodes which can be combined in various ways. Mollii has a control unit which is individually programmed for each user. The person prescribing Mollii uses a computer program to adapt the active electrodes and the intensity (which muscles are to be activated by means of current). The settings are then saved in the Mollii control unit, making it simple for the device to be used at home.
3What happens in the body when Mollii is used?
Mollii uses low level electric current to produce basic tension in the musculature. The current stimulates the antagonist to the spastic muscle. If, for example, the biceps is spastic, the triceps is stimulated which in turn makes the biceps relax. Relaxing the muscle enables active movement and a gradual improvement in function. The physiological mechanism is called reciprocal inhibition.
4What sizes are available for the Mollii suit?
Available in 24 sizes for children from size CL 104 to ladies and mens sizes. Children (CL): 104, 110, 116, 122, 128, 134, 140, 146, 152 Ladies: XS, S, M, L, XL, XXL, XXXL, SXL Mens: XS, S, M, L, XL, XXL, XXXL
5Is the Mollii suit User-friendly?
Mollii is a functional assistive device that is designed to be used in the home environment. It is simple to use. If a person can put on an ordinary garment him/herself, then he/she can put Mollii on him/herself. There is a button for on/off and a button for play/ pause. A single push of the button starts muscle stimulation, which proceeds automatically for 60 minutes. The device is used for one hour every second day.
6How often should the Mollii suit be used?
The device is used for approximately one hour on 3-4 occasions per week. For optimum effect, Mollii should be used together with physiotherapy, training, activity and movement. The effect is individual and remains for up to 48 hours.
7Mollii suit Safety
Mollii is not to be used with electrical implanted devices or medical devices that are affected by magnets, such as shunts. Consult a doctor at: cardiovascular disease, malignancy (cancer), infectious disease, fever, pregnancy, rashes or skin problems and if Mollii is intended for use with other medical devices or other medical treatment. The product is to be used according to the user manual.
