OBJECTIVE: To examine the effects of skill training on swallowing in individuals
with dysphagia secondary to Parkinson's disease (PD) and to explore skill
retention after treatment termination. DESIGN: Within-subject pilot study with
follow-up after 2 weeks of treatment and after a 2-week nontreatment period.
SETTING: Clinic in a research institute. PARTICIPANTS: Patients (N=10; mean age,
67.4y) included 3 women (mean Hoehn and Yahr score, 2.6) and 7 men (mean Hoehn
and Yahr score, 2.4). INTERVENTION: Patients underwent 10 daily sessions of skill
training therapy focused on increasing precision in muscle contraction during
swallowing using visual feedback. MAIN OUTCOME MEASURES: Data from the timed
water swallow test, Test of Mastication and Swallowing Solids, surface
electromyography (sEMG) of submental muscles, and swallowing-related quality of
life questionnaire were collected at 2 baseline sessions (conducted 2wk apart) at
the end of treatment and after 2 nontreatment weeks to assess skill retention.
RESULTS: Immediately after posttreatment, the swallowing rate for liquids
(P=.034), sEMG durational parameters of premotor time (P=.003), and preswallow
time (P<.001) improved. A functional carryover effect was seen from dry to water
swallows (P=.009). Additionally, swallowing-related quality of life improved
(P=.018). Reassessment at 2 weeks after treatment termination revealed short-term
retention of treatment effects. CONCLUSIONS: A skill-based training approach
produced functional, biomechanical, and swallowing-related quality of life
improvements in this cohort indicating compelling evidence for the effectiveness
of this novel approach for dysphagia rehabilitation in PD.
