Impaired trunk position sense and its relationship with trunk control and balance in cervical dystonia patients.

Background: Trunk position sense is an essential component of proprioception for maintaining balance. Although the loss of balance is a well-documented phenomenon in cervical dystonia (CD) patients, the evaluation of trunk position sense in this population remains a gap in the existing research.

Aims: The primary aim of this study was to compare trunk position sense between CD patients and healthy people.

Investigating the Relationship Between Maximum Phonation Time of Different Vowel Sounds and Respiratory Function.

Background: Spirometry testing, while effective, presents challenges including accessibility, cost, and patient cooperation requirements. Alternative methods for assessing respiratory function are needed. The aim of this study is to investigate whether the maximum phonation time (MPT) of different vowel sounds can serve as a reliable indicator of respiratory function in healthy young adults.
