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.

“Evaluation of a self-administered electrical stimulation using the Mollii suit for the treatment of chronic pain – a placebo-controlled trial.” The study included 50 adult study participants with chronic pain, all diagnosed with fibromyalgia. No one was on pain medication at the time of the study. The placebo trials took place two weeks prior to the effect trial with no changes in everyday lifestyle during the two-week period. The results were measured using a visual analogue scale (VAS) right before, 1 hour after, and 24 hours after the intervention.

30 children and young adults with cerebral palsy are included in the study. The study duration is six months and the children use Mollii during one hour, three to four times per week. The objective of the study is to evaluate the short and medium-term effect of the reciprocal inhibition mechanism on spasticity. The outcome measures are pain, effects on sleep, bowel movement and medication use during the 6 months of using reciprocal inhibition.
Part of the study results has been presented as a poster: "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. For the poster presentation the author chose 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.

“Pain Reducing Properties of the Mollii Suit on Adults with Chronic pain syndromes”. The open-label uncontrolled study included 200 adults (75 males and 115 females) who used Mollii suit therapy for one-hour. The aim of the study was to investigate the Mollii Suit effect on pain in adults with different pain diagnoses. 72 were diagnosed with fibromyalgia, 29 with Parkinson’s disease, while other diagnosis had a frequency <20. Patients were asked to fill a Visual Analogue Scale (VAS) just before the intervention (VAS-0), immediately afterwards (VAS-1) and twenty-four hours (VAS-24) later. A mixed-effect model, used to assess VAS change while controlling for sex, age, and diagnosis type, showed a significant drop in VAS-1 and VAS-24. The results were not affected by patients’ diagnoses, age or sex. Wearing the Mollii suit for 1 hour demonstrated significant subjective improvements in VAS scores. The abstract was orally presented at the XXIV World Congress of Neurology - WCN Oct 2019.

“A pilot study of children and parents’ experiences of the use of a new assistive device, the electro suit Mollii.” The qualitative study describes experiences from children with cerebral palsy and their parents regarding the use of the Mollii suit. Individual interviews were conducted with 6 children, age 5-10 years and their parents at the end of a 3-month trial period. All children reported some positive impact and the parents also saw improvements. Examples of positive effects observed were improved ability to perform activities, increased strength and ability to maintain body position, reduced pain, and improved sleep.

”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.

“Effects of the Inerventions method on gross motor function in children with spastic cerebral palsy.” 16 children with CP, GMFCS 1-3 were included in a randomized controlled trial. The subjects were divided into two subgroups - one group (n=8) was using Mollii and the other group (n=8) was given conventional physiotherapy. The intervention period was three weeks and Mollii was used for one hour, three times a week.The results showed improvement in gross motor function and mobility in both groups, and that conventional physiotherapy had no superior efficacy compared to the Inerventions method with 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.” The study was presented as a poster at the European Neurorehabilitation Congress, Budapest, Oct 2019. 1 Leeds Community Healthcare NHS Trust, Community Neurological Rehabilitation Service, Leeds, United Kingdom
