Evidence for effectiveness of treatment of loudness, rate, or prosody in dysarthria: a systematic review

CRD summary The review assessed interventions for global aspects of speech in individuals with dysarthria. The authors concluded that there was limited evidence of efficacy, with the exception of modification of loudness in individuals with Parkinson's disease hypokinetic dysarthria, for which there was some evidence of effectiveness. The review methodology and results were poorly reported and the reliability of the conclusion cannot be determined.
