Formatted abstract
Electromagnetic articulography (EMA) was used to examine lingual kinematics
in a heterogeneous group of seven adults with Multiple Sclerosis
(MS), including two with relapsing-remitting and five with primary progressive
forms of MS, with the latter group including two participants
with dysarthria. Tongue tip and tongue body movements were tracked as
two sentences, one loaded with alveolar consonants and the other with
velar consonants, were read aloud six times each. The results are reported
as a series of descriptive case reports. Subclinical kinematic disturbances
were identified in nondysarthric participants with MS. Specifically, the
results revealed that two MS participants (one dysarthric, one nondysarthric)
exhibited significantly increased sentence durations compared to
the control group (n = 14). Two other MS participants (one dysarthric,
one nondysarthric) exhibited significantly increased tongue movement
speed and distances, the effects of which may have counteracted to result
in comparable sentence durations to the control group. The remaining
three non-dysarthric participants with MS exhibited comparable values alto
the control group for each kinematic parameter, with the exception of
increased tongue back articulatory stiffness for one participant. The possible
mechanisms underlying the increased tongue movement duration,
speed, and distance values are explored, including compensatory strategies
for motor control disturbances.
