This study aimed to investigate the effect of Mathieson Laryngeal Manual Therapy (MLMT) following a therapeutic course in patients with primary Muscle Tension Dysphonia (MTD).
Materials and Methods: Twelve patients with primary MTD participated in this study. At first, videostroboscopy and perceptual voice assessment was performed, and the Persian version of Vocal Tract Discomfort (VTDp) scale was completed. After two and a half weeks that patients received no treatment, the assessments were repeated to evaluate the effect of spontaneous recovery. For studying the effect of MLMT, it was presented in five sessions. Then, all assessments were repeated. The frequency of supraglottic activity was elicited. For the perceptual evaluation and VTDp, the Wilcoxon nonparametric test was used to study and compare the effect of spontaneous recovery and MLMT.
Results: After spontaneous recovery, a significant difference was observed only in strain (P 0.05). There was no significant difference between spontanous recovery and MLMT based on the paerceptual voice evaluation and VTDp scale (P>0.05).
Conclusion: The MLMT can remarkably improve the supraglottic activity and perceptual characteristics of voice in primary MTD after a therapeutic course. Further studies are recommended to confirm the effectiveness of MLMT on decreasing VTD sensations.
