Conclusion: “Cleft palate and control patients showed overlapping ranges of velopharyngeal mobility, indicating that muscle function cannot be classified as normal or pathologic by a single acoustic measurement. An objective method of assessing velopharyngeal mobility may, however, provide a diagnostic tool for monitoring therapeutic progress or stagnation of logopedic therapy. As acoustic reflection measurements are noninvasive and can easily be performed without any discomfort to the patient, repeated evaluation offers the possibility of direct feedback in logopedic training. Beyond logopaedic thera0py of cleft palate patients, this technique may prove helpful in monitoring rehabilitation after cerebral apoplexy and other neurological deficits.”
