2 What is MS? An autoimmune disease Destruction of myelin Destruction of axons

3 What is MS? Etiology/Pathophysiology Cause is unknown No specific gene has been identified Age of onset Symptoms occur between the ages of Rarely manifests before age 15 or after age 60

4 Epidemiology Affects 250, ,000 people in the US Women are twice as likely as men to be affected Northern European heritage are most likely to be affected Very rare among Asians, North & South American Indians, and Eskimos Higher incidence in Northern US, Canada and Northern Europe than the rest of the world Rare between the equator and latitudes degrees north and south National MS Society

South American Indians, and Eskimos Higher incidence in Northern US, Canada and Northern Europe than

5 Environmental Factors Climate Humidity Hours of daily sunshine Resistance to certain viruses Consumption of cow s milk Toxins Trauma

6 Progression Slowly progressive disease of the CNS Four types of MS Relapsing-Remitting 80-85% Secondary Progressive 70% of the 80-85% Primary Progressive 15-20% Progressive-Relapsing Rare National MS Society

7 Symptoms & Signs Weakness Fatigue Sensory loss Bladder or bowel dysfunction Vertigo Dysphagia Ataxia Dysarthria National MS Society

8 Effects on Speech, Language and Swallowing Swallowing Language Speech Spastic Ataxic Mixed: spastic and ataxic Duffy (2005)

10 Deep Brain Stimulation 7 patients with MS with severe ataxia and intention tremor Electrodes implanted into left and/or right ventrolateral area of thalamus Limb ataxia and tremor improved Decreased articulatory performance Strained phonation in female patients Putzer, Barry, & Moringlane (2007)

11 Inspiratory Muscle Training Patients received 10 weeks of training Inspiratory Muscle Training (IMT) device One month post-training benefit Klefbeck & Nedjad (2003)

12 Expiratory Muscle Training 17 participants with MS 8 week training period Positive Expiratory Pressure (PEP) threshold trainer Maximum Expiratory Pressure (MEP) Vowel prolongation increased, e.g. [ah] No effects of dysarthria Chiara, Martin, & Sapienza (2007)

13 Rate Rigid rate control Metronome Finger tapping Alphabet board Rhythmic rate control Visipitch Auditory feedback Direct Magnitude Production (DMP) Reduced rate Improved intelligibility Loss of naturalness of speech Miller (no date)

Direct Magnitude Production (DMP) Reduced rate Improved

14 Loudness Lee Silverman Voice Treatment (LSVT) Increased vowel space Increased intelligibility Increased ease of perception Tjaden & Wilding (2004)

15 Summary Variability among MS Varying types of dysarthrias Varying degrees of severity of dysarthria No clear-cut treatment options
