Decent Essays
This study looked at the short and long-term effects of the Lee Silverman Voice Treatment (LSVT) program for individuals with dysarthria resulting from a stroke or traumatic brain injury (TBI). Five males and five females, with an age range of 19-80 years, and a range of post-onset of 6-144 months participated in this study. Seven suffered from a TBI and 2 experienced a stroke. The severity of dysarthria ranged from mild to moderately impaired. Nine of out the ten participants also presented with some form of cognitive impairment. All participants spoke and understood English and were stimulable to an improvement in the volume/quality of their voice. An ABAA experimental design was used to look at the effects of the LSVT on the participant’s speech…show more content…
The Assessment of Intelligibility of Dysarthric Speech (ASSIDS) evaluated speech intelligibility. Participants read “The Rainbow Passage”, and the middle three sentences were extracted for analysis. The Direct Magnitude Estimation (DME) was used to evaluate perceptual speech dimensions of intelligibility, loudness, and articulatory precision. A sound level meter was used to record the maximum sound pressure level (SPL). Loudness was measured by continuously recording their vocal SPL on the sound level meter for 2-3 intervals while they read the Rainbow Passage and during conversational speech. The time-frequency analysis for 32-bit Windows (TF32) software program was then used to determine their maximum fundamental frequency range. Australian Therapy Outcome Measures Scale (AusTOMs) were administered by clinicians to assess the client’s speech impairment, ability to perform everyday tasks, participation in life roles, and their general well-being. A self-report questionnaire was given to the participants, in which they rated five aspects of their communication. The participants’ primary communicative partners were also given a questionnaire that rated five different aspects of the participant’s everyday
