Differential effects of voice therapies on neurovegetative symptoms and complaints.
In previous studies , female patients in all age categories with a nonorganic dysphonia were found to report significantly more autonomic symptoms and complaints than healthy controls . After voice therapy , there was a highly significant reduction in the amount of autonomic symptoms and complaints ( related or not related to voice ) . The present prospect i ve study with a matched control group is design ed to test the hypothesis that a specific kind of therapy is more efficient than the usual approaches in reducing these neurovegetative symptoms and complaints .  Two matched groups of 34 patients diagnosed with nonorganic dysphonia and referred for voice therapy answered a question naire of 46 questions with 3 subsets and a consistency control . They received either " coordination therapy " (CTh)--a holistic approach addressing functional , personal and emotional aspects -- or a conventional voice therapy ( approximately 15 sessions ) . All patients again filled in a similar question naire after approximately 6 months . After therapy , there is in general a highly significant reduction in the amount of autonomic symptoms and complaints ( related or not related to voice ) , to such an extent that patients report on average no more general neurovegetative symptoms and complaints than those of healthy controls . Symptoms and complaints of other nature ( validity control ) are not influenced . When compared with patients receiving conventional therapy , those who received CTh demonstrate a significantly higher reduction for the subset " neurovegetative symptoms/complaints related to voice and speech .
