Multiple Sclerosis Clinical Trial
Official title:
Efficacy of tDCS on Pain Experience in People With Multiple Sclerosis: A Pilot Randomized Control Trial
Pain is a common symptom experienced by people with MS and can significantly interfere with participation in the activities of daily living and adversely affect health-related quality of life. Pain in people with MS has the potential to become chronic, as a consequence of neuronal reorganization. Transcranial Direct Current Stimulation (tDCS) promotes the modulation of brain activity and its prolonged and continuous application can effect plastic modification. Combining tDCS with rehabilitation treatment may have effect in reducing pain in people with MS. This is a pilot randomized control trial to test the effects of tDCS in MS-related pain rehabilitation, its efficacy on pain (intensity, quality, interference with physical functioning), catastrophizing, emotional functioning and quality of life. Furthermore, we will explore the effects on pressure pain threshold and EEG recording. Correlations between sample characteristics and pain features will be investigated. Considering role of tDCS on neuropsychological functions, selective attention will be assessed.

Secondary | Pain Catastrophizing Scale (PCS) | Assessment of a tendency to misinterpret or exaggerate apparently threatening situations that can lead to increased sensitivity to pain. | 1 week, 4 weeks, 8 weeks | |
Secondary | Coping Strategies Questionnaire (CSQ) | Assessment of the frequency of coping strategies in response to pain. | 1 week, 4 weeks, 8 weeks | |
