OBJECTIVE: To investigate whether the direct application of vibratory stimuli
inhibits spasticity in the hemiplegic upper limbs of post-stroke patients.
DESIGN: A randomized controlled study. SUBJECTS: Thirty-six post-stroke patients.
METHODS: Patients were randomly allocated to the "Rest group", "Stretch group",
or "Direct application of vibratory stimuli group". After relaxing in a supine
posture for 30 min, subjects received the interventions for 5 min. The Modified
Ashworth Scale scores and F-wave parameters were recorded before, immediately
after and 30 min after each intervention. RESULTS: The Rest group showed no
significant changes in F-wave parameters and Modified Ashworth Scale scores. The
Stretch group showed a tendency to decrease in F-wave amplitude and F/M ratio
immediately after the intervention, but not 30 min later. The Direct application
of vibratory stimuli group showed significant improvements in F-wave parameters
and Modified Ashworth Scale scores immediately after the intervention, which
remained 30 minutes later. The changes in F-wave parameters and Modified Ashworth
Scale scores observed in the Direct application of vibratory stimuli group
significantly differed from those in the Rest group and the Stretch group.
CONCLUSION: The direct application of vibratory stimuli has anti-spastic effects
in the hemiplegic upper limbs of post-stroke patients.
