The purpose of this study was to exam the effects of music therapy
intervention focused on singing and playing wind instruments on the
improvement of phonation and articulation for the children with cerebral
palsy. The study was conducted in N national rehabilitation center from
June, 7, 2012 to August, 16, 2012, twice a week. Total number of music
therapy sessions were 20 times. The subjects were 8 -experimental group 4
children, control group 4 children- whose age ranged from 5.9 years to 8.6
years. The music therapy for the experimental group children was
implemented in individual session form for 30 minuets. The measurement of
the effectiveness of music therapy was analysed about the differences
between the experimental group and the control group by using Praat. The
data of experimental group and control group -maximum phonation time,
jitter, shimmer, pitch, intensity, formant 1, 2, 3- were analysed with SPSS
V.19 program which was used with paired sample test –wilcoxon test- and
independent sample test -Mann-Whitney U test.
The results of this study, first, the phonation quality was increased 11
times on maximum phonation time scores, decreased 95%, 77% on jitter and
shimmer scores, increased 50%, 71% on pitch and intensity scores in
experimental group after music therapy intervention with singing and playing
wind instruments focused on the respiratory training. On the other hand, the
control group nearly not changed.
Second, the articulation improvement was increased 31%, 41% on formant 1
and 2 scores, decreased 20% on formant 3 scores in experimental group after
the respiratory training focused on music therapy intervention. Chin, tongue
and lips showed positive change on the coattails of this articulation
improvement. On the other hand, the control group nearly not changed.
Meanwhile, except for the formant 1, 2 and 3, the maximum phonation time,
jitter, shimmer, pitch, intensity scores indicated experimental group's paired
sample test (p<.05). Except for the formant 1, the maximum phonation time,
jitter, shimmer, pitch, intensity, formant 2 and 3 scores indicated experimental
group and control group's independent sample test(p<.05).
As a result, the findings of this study showed that respiratory training
focused on music therapy intervention positively effected on the phonation
and articulation improvement of the children with cerebral palsy.
