About

Spasticity is a common and debilitating complication in neurological conditions such as multiple sclerosis, cerebral palsy, and stroke. Stroke, a leading cause of global disability and death, occurs when blood flow to the brain is disrupted, causing neuronal damage. Approximately 80% of strokes are ischemic, with 20% being hemorrhagic. Several factors, including age, sex, vascular conditions, and lifestyle choices, increase the risk of stroke. Spasticity affects 19-28% of stroke survivors in the short term and up to 46% in the long term, severely impacting mobility and quality of life. Management typically involves pharmacological and nonpharmacological interventions, though these often have limited effectiveness and side effects. In this context, non-invasive techniques like transcutaneous stimulation with the EXOPULSE Mollii suit may offer a valuable alternative for managing spasticity and its associated symptoms.

  • Suffering from other somatic or neuropsychiatric diagnoses (e.g., arrhythmias, uncontrolled epilepsy, diseases causing osteoarticular and muscular pain).
  • Having a body mass index above 35 Kg/m2.
  • In case of introducing a medical device other than EXOPULSE Mollii suit during the study period.

34 participants in 2 patient groups

Experimental Condition
Active Comparator group
Description:
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. These parameters were previously found to be safe in human studies. Based on the clinical exam of each patient, the spastic muscles will be targeted. EXOPULSE Mollii Suit is used for activation of weak muscles or relaxation of spastic muscles mediated by a physiological reflex mechanism referred to as reciprocal inhibition. By sending an electrical signal to an antagonistic muscle, the spastic muscle will subsequently relax.
Treatment:
Device: EXOPULSE MOLLII SUIT (active)
Control Condition
Sham Comparator group
Description:
In the control condition, the patients will receive a sham stimulation, for which the control unit will be programmed to start stimulating for 1 minute then it will shut off. There is no risk related to the sham intervention since it consists of applying the same parameters used for the active session (low frequency: 20 Hz; current intensity: 2 mA; pulse width ranging from 25 to 170 µs) but for a shorter duration of time (1 minute instead of 1 hour).
Treatment:
Device: EXOPULSE MOLLII SUIT (sham)
