Abstract
|
|
|
Objectives: The aim of this study was to investigate whether Doppler ultrasound device is applicable for the evaluation of facial palsy patients.
Methods: A total of 25 patients participated in the first assessment and 22 of them finished a follow-up assessment one week later. An assessment comprised of a Minimax-Doppler-K device examination on bilateral acupoints ST5, SI19, ST2, and BL1, House-Brackmann grading, and subjective symptom questionnaire. Measurement reliability was assessed and clinically meaningful variations of Doppler measurement values were explored.
Results: Doppler ultrasound examination revealed a significant difference of some measurement values between values of the symptom side and the contralateral side, between groups of severe paralysis and moderate paralysis, and between groups of short duration(0-3 weeks) and long duration (3weeks-5 months) by non-parametric analyses (p<0.05). Several re-examination values showed a significant correlation with the first examination values by Spearman’s correlation tests (p<0.05).
Conclusions: This study revealed several possibilities for the clinical application of this device. Further validity tests and device improvements for a user’s convenience would be helpful for its practical application.
