  • Purpose The primary purpose of this 900 project was to explore the effects of Lung Volume Recruitment (LVR) on voice and speech in patients with Amyotrophic Lateral Sclerosis (ALS) through the development of analysis protocols for several dependent measures. Methods Speech and voice data from a larger study were analyzed using protocols developed for the purposes of this project. Results No significant therapeutic benefit was found for any dependent measure examined in this study. Study protocols were developed and students achieved high inter-rater reliability when analyzing data according to guidelines. Implications Although researchers and clinicians have suggested a therapeutic benefit of LVR on voice and speech in patients with ALS, the results of the current study do not support these claims. Possible reasons for the findings and directions for future research are discussed.
