Outline of Final Research Achievements

In clinical situations, Speech Therapists are likely to encounter patients who mention symptoms of fatigue in conversation. The previous research indicates the fatigue in patients with Parkinson’s disease, and Myasthenia Gravis. This study tested the assumption that speech is susceptible to fatigue in persons with dysarthria. After speech-like exercises, patients evaluated VOT, speech intelligibility, Tongue maximal pressure (kPa) was measured by the instrument @JMS, and patients rated fatigue with visual analogue scale (%).
1. Speech-related fatigue in patients with oral cancer indicated temporal improvement. Many patients revealed recovery of fatigue after 7-8months of operation, the first tongue pressure changed, and self-perceived fatigue gradually decreased.2. The most factors might impact speech-related fatigue are tongue pressure, speech intelligibility, chemo/radiation therapy.
