Investigation of the Relationship Between Arterial Stiffness and Pulmonary and Extrapulmonary Features in Patients With Ankylosing Spondylitis

Overview

The aim of this study was to investigate the relationship between arterial stiffness and pulmonary and extrapulmonary features in patients with ankylosing spondylitis.

Primary outcome measures

  • Arterial stiffness [Time frame: 1st day]
  • Respiratory muscle strength [Time frame: 1st day]
  • Respiratory muscle endurance [Time frame: 1st day]
  • Exercise capacity [Time frame: 1st day]
  • Peripheral muscle strength [Time frame: 1st day]
  • Muscle function [Time frame: 1st day]
Secondary outcome measures (6)
  • Physical activity [Time frame: 1st day]
  • Forced vital capacity [Time frame: 1st day]
  • Forced expiratory volume in one second [Time frame: 1st day]
  • Forced expiratory volume in one second/forced vital capacity ratio [Time frame: 1st day]
  • Peak expiratory flow [Time frame: 1st day]
  • Forced mid-expiratory flow [Time frame: 1st day]
