effects of using the electrodress mollii on spasticity

Conditions: Spasticity, Muscle; Stroke; Electric Stimulation Therapy

Summary: spasticity is a common manifestation of lesions of central motor pathways, such as after stroke, traumatic brain or spinal cord injury and in cerebral palsy and is associated with increased impairments and disabilities. spasticity may be associated with pain and contractures, caused by muscle weakness, reduced muscle length and volume that add to the disability.treatments of spasticity comprise physical therapy, pharmacological agents and surgical treatment. recently, a systematic review concluded that transcutaneous, electric nerve stimulation may have beneficial effects on spasticity and activity performance after stroke, which lends support to the new treatment method mollii, which will be evaluated in this study.the mollii suit provides electric stimulation through multiple electrodes places in a tight fitting suit. this study relates to the clinical trials performed at the university department of rehabilitation medicine at danderyd hospital in stockholm and comprises an initial study of effects on spasticity ("mechanical substudy") and a following, exploratory treatment trial ("clinical substudy") in patients with spasticity after stroke.
