Multiple Sclerosis (MS) patients with subjective dysphagia will be tested for tongue strength fatigue using a strictly defined fatigue paradigm. A maximum of 40 sets will be performed, each set consisting of 5 repetitions of 80% of maximum isometric pressure (MIP) at the anterior tongue, followed by a MIP at the anterior tongue. Cut-off criteria are a MIP \<50% of the baseline MIP, pronounced subjective discomfort and/or exceeding the allocated test time of 30 minutes.
Eligibility is Mini-Mental State Exam-score (MMSE) \> 23, a Eating Assessment Tool-score (EAT-10) \> 3, or a Functional Oral Intake Scale-score (FOIS) \< 7, or failing the Yale Swallow Protocol.
