This was a Phase I study that examined the effects of a well defined intensive behavioral voice treatment, LSVTRTM, on communication behaviors of five people with dysarthria secondary to stroke. A single-subject A-B-A research design was used to detect whether there was a treatment effect. The results for each participant were evaluated for the following acoustic dependent variables; (1) SPL for speech tasks and sustained "ah", (2) duration of sustained "ah", (3) measures of phonatory stability for sustained "ah" including relative average perturbation and pitch perturbation quotient, (4) semi-tone standard deviation as a measure of F0 variation, and (5) rate of speech during paragraph reading. Additional dependent variables included listener ratings of word and sentence intelligibility and an estimation of overall preference as well as self and family ratings on the Voice Handicap Index and a visual analog scale. Qualitative data included interviews with Ps and family members regarding the functional impact of treatment on communication.

520 $a This was a Phase I study that examined the effects of a well defined intensive behavioral voice treatment, LSVTRTM, on communication behaviors of five people with dysarthria secondary to stroke. A single-subject A-B-A research design was used to detect whether there was a treatment effect. The results for each participant were evaluated for the following acoustic dependent variables; (1) SPL for speech tasks and sustained "ah", (2) duration of sustained "ah", (3) measures of phonatory stability for sustained "ah" including relative average perturbation and pitch perturbation quotient, (4) semi-tone standard deviation as a measure of F0 variation, and (5) rate of speech during paragraph reading. Additional dependent variables included listener ratings of word and sentence intelligibility and an estimation of overall preference as well as self and family ratings on the Voice Handicap Index and a visual analog scale. Qualitative data included interviews with Ps and family members regarding the functional impact of treatment on communication.
520 $a Multiple analyses were used to assess the treatment effect on the dependent variables. These included; (1) visual inspection of the data in terms of trend and level of performance during phases of the study, (2) a difference in mean relative to standard deviation (SD) to determine statistical significance, (3) effect size to estimate the magnitude of treatment effect if one was identified, and (4) the C statistic to determine whether there was a statistically significant trend in sequential evaluation measures.
520 $a The data demonstrated that the five participants with chronic stroke included in this study increased loudness as a result of intensive voice treatment and there was a positive impact on communication. These findings add to the existing literature of the efficacy of LSVTRTM in the treatment of people with PD and other neurological diagnoses. Further studies with additional participants are needed to determine the nature of the motor changes following intensive voice treatment and whether outcomes can be generalized to this population.
