Efficacy and Cost-effectiveness of Spasticity Treatment With Multifocal TENS

Spasticity is a common consequence of injury to the central nervous system and can be a major problem in motor function and everyday activities. A method for treating spasticity that applies low-amplitude electrical stimulation through a garment with built-in electrodes, Mollii® (Elektrodress), has been developed. The garment is to be used in combination with individualized training and the stimulation is mainly given to antagonists of spastic muscles. The general objective of this study is to evaluate the efficacy of and costs associated with the Mollii® treatment of spasticity due to stroke or cerebral palsy. Primary objectives are; * to study whether treatment with the Mollii® improves function and activity * to evaluate the cost-effectiveness of the treatment, from both a health-care perspective and a societal perspective. Secondary objectives are; * to study whether there are differences in treatment effect between the stroke and the Cerebral Palsy groups in a subgroup-analysis * to assess compliance with treatment * to report any adverse effects.
