About this study

this study for investigation of correlation between voice pitch and tension of suboccipital muscles

Read the detailed description

participants will be assigned randomly , normal people i will use 2 instruments first : compturized speech lab (CSL) to analyze voice pitch second: electromyography EMG to measure suboccipital muscle tension during speech this task will be repated twice first one during normal speech , second one during change in voice pitch

Keywords
voice pitch changes, tension of suboccipital muscles, correlational study
Medical subject headings
Dysphonia

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. tension of suboccipital muscles

    Measured: immediately during voice pitch changes

Secondary outcomes (1)
  1. suboccipital muscles tension

    suboccipital muscles tension will be measured by Electromyography during change of voice pitch

    Measured: 5 minutes :tension will be measured twice during speech
