McHenry, M.A., Minton, J.T., Wilson, R.L., & Post, Y.V. (1994). Intelligibility and nonspeech orofacial strength and force control following traumatic brain injury. Journal of Speech and Hearing Research, 37, 1271-1283. Type of Study Research study Subjects 11 males, 9 females; ages 16-35; 4-106 months post-injury Diagnoses Severe TBI Speech Condition Intelligibility deficits: 3%-100% sentence intelligibility Purpose To determine differences in nonspeech orofacial-force generation for range of intelligibility To determine if there is differential impairment in force generation between intelligibility groups according to level of force tested To determine if there is differential impairment force generation between intelligibility groups according to orofacial structure Methods Oral-peripheral exam Laryngeal resistance estimation Dynamic and sustained nonspeech orofacial force testing Audiotaping CAIDS Results More and less intelligible subjects did not substantially differ in dynamic and sustained force generation Other factors contribute to intelligibility besides dynamic and sustained force generation Treatment Implications Assessing individual articulators may help in designing treatment intervention but differential impairment cannot be determined with nonspeech orofacial force generation.   Assessment Treatment Speech Characteristics Books and Book Chapters Instruments Other Links Search Home   To return to the Abstract References, click on Assessment, Treatment, or Speech Characteristics or use your browser to go Back.
