Abstract
Purpose: The primary objective of this study was to determine if speech and pause measures obtained using a passage reading task and timing measures from a monosyllabic diadochokinesis (DDK) task differ across speakers of Canadian French diagnosed with amyotrophic lateral sclerosis (ALS) presenting with and without bulbar symptoms, and healthy controls. The secondary objective was to determine if these measures can reflect the severity of bulbar symptoms.
Method: A total of 29 Canadian French speakers with ALS (classified as bulbar symptomatic [n = 14] or pre-symptomatic [n = 15]) and 17 age-matched healthy controls completed a passage reading task and a monosyllabic DDK task (/pa/ and /ta/), for up to three follow-up visits. Measures of speaking rate, total duration, speech duration, and pause events were extracted from the passage reading recordings using a semi-automated speech and pause analysis procedure. Manual analysis of DDK recordings provided measures of DDK rate and variability.
Result: Group comparisons revealed significant differences (p = < .05) between the symptomatic group and the pre-symptomatic and control groups for all passage measures and DDK rates. Only the DDK rate in /ta/ differentiated the pre-symptomatic and control groups. Repeated measures correlations revealed moderate correlations (rrm = > 0.40; p = < 0.05) between passage measures of total duration, speaking rate, speech duration, and number of pauses, and ALSFRS-R total and bulbar scores, as well as between DDK rate and ALSFRS-R total score.
Conclusion: Speech and pause measures in passage and timing measures in monosyllabic DDK tasks might be suitable for monitoring bulbar functional symptoms in French speakers with ALS, but more work is required to identify which measures are sensitive to the earliest stages of the disease.
期刊介绍:
International Journal of Speech-Language Pathology is an international journal which promotes discussion on a broad range of current clinical and theoretical issues. Submissions may include experimental, review and theoretical discussion papers, with studies from either quantitative and/or qualitative frameworks. Articles may relate to any area of child or adult communication or dysphagia, furthering knowledge on issues related to etiology, assessment, diagnosis, intervention, or theoretical frameworks. Articles can be accompanied by supplementary audio and video files that will be uploaded to the journal’s website. Special issues on contemporary topics are published at least once a year. A scientific forum is included in many issues, where a topic is debated by invited international experts.
