چکیده

مقدمه واهداف
سیستم تنفسی منبع تامین کننده انرژی جهت ارتعاش نرمال تارآواها بدون هیچ­گونه فشار مضاعف بر عضلات داخلی و خارجی حنجره بوده و برای کاربران حرفه ای صوت از اهمیت ویژه ای برخوردار می باشد. با توجه به شیوع بالای اختلالات صوتی در آموزگاران به عنوان یکی از گروه­های مهم کاربران حرفه ای صوت، پژوهش حاضر برای مقایسه کفایت تنفسی به­وسیله­ی دو معیار MPT وs/z Ratio در دوگروه آموزگاران با و بدون خطر ابتلا به مشکلات صوت بر اساس چک لیست SIVD طراحی شد.
مواد و روش ها
پژوهش حاضر درچهارچوب یک پژوهش مقطعی بر روی 100 آموزگار مقطع ابتدایی انجام شده است. آموزگاران ابتدا چک لیست SIVD را تکمیل کرده و پس از آن معیار های MPT و s/z Ratio آن­ها محاسبه شد. داده ها توسط نرم افزارSPSS مورد تجزیه و تحلیل قرار گرفتند.
یافته ها
در آموزگاران مرد تفاوت معناداری بین دو گروه به لحاظ میانگین MPT وs/z Ratio دیده نشد(05/0p>). در گروه آموزگاران زن میانگین MPT در گروه در معرض ریسک ابتلا به مشکل صوت و گروه بدون ریسک ابتلا تفاوت معنادار بود (01/0Pv= ).
نتیجه گیری
نتایج نشان می­دهد که کفایت تنفسی در آموزگاران به شکل کلی کمتر از نرمال است اما با وجود عدم تفاوت معنادار بین میانگین ها در دو گروه با ریسک ابتلا به مشکل صوت و بدون آن، می­توان گفت که با وجود اهمیت کفایت تنفسی در آواسازی، احتمالا به تنهایی تاثیر مستقیمی بر خطر ابتلا به مشکلات صوت ندارد.

چکیده [English]

Background and aim: The respiratory system is considered as a source of energy for normal vibration of vocal folds with no extra forces on external and internal laryngeal muscles. This system is specifically important in professional voice users. With regard to the high incidence of voice problems among teachers, as a significant group of professional voice users, the present study was conducted to investigate the respiratory competency using MPT and s/z Ratio criterion in teachers with and without voice problems risks classified based on their scores on Screening Index for Voice Sisorder (SIVD).
Materials and Methods: The current cross-sectional study was carried out on 100 elementary school teachers. The participants first completed the SIVD questionnaire, and then the MPT and the s/z Ratio were calculated for each teacher. Data analysis was run using SPSS (v. 18).
Results: No significant difference was observed between means of MPT and s/z Ratio in male participants in the two groups. However, the difference between means of MPT in female participants was found to be significant (p= 0.01).
Conclusion: The results suggest that although respiratory competency was lower than normal in all the teachers, it cannot solely be the cause of developing the risk of voice problems.
