Dysphagia is a disabling, life-threatening symptom that can cause death in Multiple Sclerosis people (pwMS) through aspiration pneumonia. Speech therapists use behavioural therapies (compensatory and rehabilitative) to alleviate such swallowing problems, with limited benefit. Compensatory strategies such as postural changes and changes in food consistency, have been found to be partially effective, especially in patients with mild dysphagia and may be ineffective in patients with more severe dysphagia. The rehabilitative strategies include "no swallow exercises" which aim to strengthen isolated muscles used in swallowing (such as tongue strengthening) and "swallowing exercises" that aim at strengthening all the muscles used in swallowing while executing a hard, effortful, or prolonged swallow. To date, no randomized clinical trials have shown that rehabilitative strategies are effective. Neuromuscular electrical stimulation (NMES), often referred to as electrical stimulation, was introduced as a novel therapy for dysphagia in the late 2001. The principles of NMES in the limb rehabilitation literature are well established. However published protocols applying NMES to swallowing function have shown mixed results in people with stroke and only one study was published on MS people. This will be a double blinded, randomized clinical trial (patients and research staff blinded) with two arms: standard speech therapy plus Active NMES vs speech therapy with Sham NMES. The aim of this study is to determine whether NMES added benefit to a therapy program comprised of standard swallowing exercises in dysphagic pwMS.
