The effects of patterned sensory enhancement (PSE) music on muscle power and
movement control in children with spastic diplegia (SD) during loaded
sit-to-stand (LSTS) were investigated. Twenty-three children with SD aged 5 to 12
years were recruited. Individualized PSE was composed by a music therapist based
on each subject's sit-to-stand (STS) movement with 50% 1-repetition maximum load.
Each subject performed LSTS continuously for eight repetitions under randomly
assigned music or no-music (Control) conditions while the kinematic and kinetic
data were measured simultaneously. For the music condition, PSE music was played
only during the first five repetitions (PSE condition), and the following three
repetitions were referred to as the Continuation condition. Paired t- or Wilcoxon
signed rank tests were used to compare the variables between the PSE and Control
conditions, and between the Continuation and Control conditions. Compared to the
Control condition, greater peak knee extensor power (P=0.009), greater total
extensor power (P=0.015), and better center-of-mass smoothness (P=0.01), but less
movement time (P=0.003) were found in the PSE condition. Significant effects of
the PSE music on the above variables were also found for Continuation condition.
The current results showed that individualized PSE music helped improve the
performance of LSTS in children with SD. The associated biomechanical features
also continued to exist in subsequent movement cycles after the music had ceased.
These findings suggest that therapy using LSTS combined with PSE music may be
beneficial for rehabilitating children with SD.
