Submental Muscle Tissue Compliance During Relaxation, Contraction, And After Tone-Modification Interventions, Heather M. Clark, Nancy Pearl Solomon Nov 2010

Submental Muscle Tissue Compliance During Relaxation, Contraction, And After Tone-Modification Interventions, Heather M. Clark, Nancy Pearl Solomon

International Journal of Orofacial Myology and Myofunctional Therapy

Deviations in muscle tone are presumed to accompany speech motor control deficits in select forms of dysarthria, although there is little confirmation of these associations. For patients experiencing neuromuscular impairments, therapeutic interventions and/or principles have been devised to alleviate tone deviations where they occur and to prevent the development or exacerbation of tone deviations. Potentially therapeutic effects of these interventions on muscle tone in the speech musculature have not been studied empirically. One reason for the paucity of research is that tools for assessing muscle tone in the speech musculature are not generally available. This pilot study explored the feasibility …


Dual-Task Interference: The Effects Of Verbal Cognitive Tasks On Upright Postural Stability In Parkinson's Disease, J. D. Holmes, M. E. Jenkins, Andrew M. Johnson, S. G. Adams, S. J. Spaulding Feb 2010

Dual-Task Interference: The Effects Of Verbal Cognitive Tasks On Upright Postural Stability In Parkinson's Disease, J. D. Holmes, M. E. Jenkins, Andrew M. Johnson, S. G. Adams, S. J. Spaulding

Occupational Therapy Publications

Although dual-task interference has previously been demonstrated to have a significant effect on postural control among individuals with Parkinson's disease, the impact of speech complexity on postural control has not been demonstrated using quantitative biomechanical measures. The postural stability of twelve participants with idiopathic Parkinson's disease and twelve healthy age-matched controls was evaluated under three conditions: (1) without a secondary task, (2) performing a rote repetition task and (3) generating a monologue. Results suggested a significant effect of cognitive load on biomechanical parameters of postural stability. Although both groups increased their postural excursion, individuals with Parkinson's disease demonstrated significantly reduced …
