Clinical studies

Published and ongoing studies


A number of clinical studies are ongoing in several countries, led by renown hospitals and doctors, including Karolinska Institutet and Hvidovre Hospital, on a large panel of more than 350 adults and children, most of which are diagnosed with cerebral palsy (CP), multiple sclerosis (MS) or stroke. The studies completed to date show in part improvements in spasticity, muscle relaxation, associated pain relief, sleep as well as physical abilities such as range-of-motion, balance, hand-arm functions, walking and mobility, and thus in overall quality of life.

“Qualitative study of a transcutaneous electrical stimulation garment (Mollii suit) to reduce pain, improve capabilities and quality of life in children with cerebral palsy.” The qualitative part of the study aimed to examine the acceptability, outcomes of use and costs of the Mollii Suit as an intervention of ten children with cerebral palsy. The intervention period was 6 weeks, in which the participants used Mollii 1 hour every other day. The data was collected via a semi-structured interview with participants and their parents. The results show, among other things, that Mollii is perceived to be 'relaxing' and easy to include in everyday life. Other positive changes were reported such as improvement in attention, energy levels, concentration, sleep, improved standing posture, joint positioning, motor skills and reduced pain. The quantitative part of the study is expected to be published in the end of 2019.

"The Mollii-suit - A novel method using reciprocal inhibition on children with cerebral palsy, GFMCS IV-V. A 6 month prospective study." 30 children and young adults with cerebral palsy were included in the study where the intervention period were six months and the children used Mollii during one hour, three to four times per week. The purpose of this study was to investigate whether a novel method of using reciprocal inhibition affects range of motion and spasticity on children with cerebral palsy. The results shows an improvement in spasticity in the hamstrings muscle group and quadriceps measured with Modified Ashworth and Modified Tardieu Scale. The passive ROM showed a suggestive trend towards statistically significance different in hamstrings and quadriceps. Individualized goals (GAS) related to function and mobility improved significantly throughout the intervention period.

”Evaluation of a self-administered transcutaneous electrical stimulation concept for the treatment of spasticity – a randomised placebo-controlled trial.” The study included 27 participants with spasticity - 12 with cerebral palsy and 15 with stroke. The intervention period was 12 weeks, divided into two periods. 6 weeks with an active Mollii suit and 6 weeks with an inactive Mollii suit (placebo suit). Goal attainment scaling (GAS), change in mobility, arm-hand ability, spasticity and pain were measured at baseline and after 6, 12 and 18 weeks. The results showed an improvement in walking speed. And a significant difference in GAS was also shown during the period of active use of Mollii.

“Single Case Study: Low threshold electrical stimulation (LTES) using the Mollii suit as treatment modality for severe ataxia in an adult with Multiple Sclerosis” A single case study, was performed on a 40-year old male with primary progressive multiple sclerosis and ataxic symptoms. The ataxia was so significant that the patient had lost the ability to stand within a year. The aim of the study was to see if the use of the LTES (low threshold electrical stimulation) Mollii suit could reduce symptoms of ataxia and improve function in the patient. The outcome measures were Modified Fatigue Impact Scale, Motricity Index, Scale for the Assessment and rating of ataxia (SARA), Arm Activity Measure (ArMA), video of arm movements and slide transfers. The participant wore the Mollii suit for one hour every day which resulted in significant progress in all the above measurements. He was also able to walk 100 metres using a pulpit frame with assistance and he also demonstrated increased independence when feeding and drinking. The author of the study concluded: “It was clearly evident that the Mollii suit was very beneficial to control ataxic movements and demonstrate significant improvements in functional tasks.” Poster at the European Congress of Neuro Rehabilitation, Budapest, Hungary 2019
