Exopulse Mollii Suit, Motor Functions & CP Children With Cerebral Palsy

Study Overview
=================
Brief Summary
-----------------
Cerebral Palsy (CP) is is estimated to be around 1.5-3 per live birth, with prenatal factors accounting for 75% of cases. CP appears in early childhood and persists with age and is characterized by permanent lesions or abnormalities affecting the immature brain. It mainly occurs as a motor system disorder (e.g., abnormal movements or posture) with the presence of hemiplegia, diplegia or tetraplegia, and spastic, dyskinetic or atactic syndromes. .This study will explore the potential clinical benefits of the Molliimethod in children with cerebral palsy. Spasticity impacts balance and mobility, halts the patients quality of life and their ability to perform their activity of daily living, and could also increase the risk of fractures and falls. Available interventions that aim on improving spasticity are facing limitations such as varios side effects. Therefore, developing novel therapies such as the EXOPULSE Mollii Suit could help to overcome such limitations and noninvasively improve balance, mobility, quality of life and reduce spasticity and pain in children with CP.

Detailed Description
-----------------
Cerebral Palsy is a heterogenous group of disorders that was first introduced in the literature in 1843 by Little who described musculoskeletal deformities and spastic limbs in the context of neonatal hypoxia. The clinical classification of CP could be based on several system. For instance, the classification by Balf and Ingram takes into account the type, lesion location and severity of the clinical symptoms, and entails the following CP types that could be further considered as mild, moderate or severe: diplegia, hemiplegia or tetraplegia with the presence of spastic syndromes, dyskinetic syndromes and ataxia. In the context of CP, spasticity is a frequent and debilitating symptom that could occur in 70-89% of individuals. Spasticity could subsequently alter the development of motricity, quality of life, patients' self-es-teem and seems to be associated with several health consequences, namely pain, infections, joint deformities, thrombosis and bedsores. Managing spasticity in CP include the combination of pharmacotherapy, motor rehabilitation, and surgical interventions. It is now widely accepted that spasticity impacts balance and mobility, halts the patients quality of life (e.g., urinary symptoms, sexual dysfunction, mood symptoms, low self-esteem) and their ability to perform their activity of daily living, and could also increase the risk of fractures and falls. The available interventions targeting spasticity are faced with some limitations. For instance, botulinum toxin injection does not seem to improve motor functions and quality of life as well as available oral agents are challenged by their potential side effects. Therefore, developing novel therapies would help to overcome the actual limitations. Transcutaneous Electrical Nerve Stimulation (TENS) has proven some efficacy in spasticity management. However, one should note that practical difficulties could arise when using TENS at home or in clinical practice (i.e., correctly attaching electrodes). To overcome these limitations, the Exopulse Mollii Suit has been developed by Exoneural Network AB (initially Inerventions AB), a Swedish medtech company. It represents an innovative approach for non-invasive electrostimulation to reduce spasticity and improve motor function. Based on the theoretical and practical background outlined above, this study will explore the potential clinical benefits of the Mollii-method in children with cerebral palsy. The overall aim of this study is to evaluate the short-term impact of Exopulse Mollii Suit on balance in pediatric patients with cerebral palsy who are suffering from spasticity as well as assessing the effects of Exopulse Mollii Suit on spasticity, mobility, pain, and quality of life.

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Crossover Assignment
Interventional Model Description: Active Comparator: Active Active sessions will last 1 hour each. The following parameters will be used for electric stimulation: low frequency (20 Hz), low current intensity (2 mA), with a small pulse width of 25-170 microseconds. Sham Comparator: Sham In the sham condition, the control unit will be programmed to start stimulating for 1 minute then it will shut off.
Masking: Triple


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Active Stimulation<br>Active sessions will last 1 hour of stimulation per day for 2 weeks. The following parameters will be used for electric stimulation: low frequency (20 Hz), low current intensity (2 mA), with a small pulse width of 25-170 microseconds. | Device: Exopulse Mollii Suit<br>* Exopulse Mollii suits consists of a body Garments (Jacket and Pants) and a control unit. The body Garments (Jacket and Pants) is a suit with 58 embedded electrodes that can stimulate 40 groups of muscles, conductive wires and connectors to a detachable control unit, whose intended purpose is to transmit electric pulses from the control unit to key nerves and corresponding muscle groups throughout the body. The control unit is a battery powered electrical device which sends low intensity electric pulses through connectors to the Body Garments which in turn transmits the pulses from the connectors to key nerves and corresponding muscle groups throughout the body.<br>|
| Sham Comparator: Sham Stimulation<br>In the sham condition, subjects will be asked to wear the device for 1 hour per day for 2 weeks. During 1 hour use per day, the actual stimulation will last only 1 minute and then will shut off. | Device: Sham Exopulse Mollii Suit<br>* In the sham condition, the control unit will be programmed to start stimulating for 1 minute then it will shut off.<br>|
