A 55-year-old male subject was treated with a two-tiered neurotherapy approach for a period of six months beginning approximately one year after a left-side CVA. Medical evaluation revealed left posterior temporal/parietal infarctions secondary to occlusion of the left internal carotid artery. The patient complained of hesitant speech with word finding difficulty and paraphasia, difficulty focusing his right eye, lack of balance and coordination, poor short-term memory, poor concentration, anxiety, depression, and tinnitus. A quantitative electroencephalograph (QEEG) analysis revealed increased left-side 4-7-Hz activity and alpha persistence on eye opening. Two neurotherapy approaches were used beginning with electroencephalographic entrainment feedback (EEF). This was followed by neurofeedback to inhibit 4-7 Hz and increase 15-21 Hz over sensorimotor and speech areas. At the conclusion of treatment there were significant reductions in slow-wave activity. Improvement was evident in speech fluency, word finding, balance and coordination, attention, and concentration. Depression, anxiety, and tinnitus were greatly reduced.
This report of a case study of an unusual child aims to set the use of electropalatography (EPG) within the wider context of general communication therapy. It concerns a child of 12 years, diagnosed as having congenital suprabulbar paresis (Worster-Drought syndrome) who presents with severe developmental dysarthria; his speech is unintelligible, with hypernasality and glottalised articulation. His baseline EPG assessment patterns show minimal tongue-to-palate contact for all lingual obstruents, although he can demonstrate some tongue movement for non-speech skills, and has a slow but near normal swallow pattern. EPG therapy was used for tongue movements, but was adversely affected by his velopharyngeal insufficiency.
