Functional capacity, physical activity, and arterial stiffness in patients with systemic sclerosis.

Objectives: Systemic sclerosis (SSc) is a complex immune-mediated connective tissue disease, involving skin manifestations, vascular features, and organ-based complications that may affect functional capacity and physical activity. Functional capacity and physical activity are associated with arterial stiffness; however, this relationship has not been evaluated in patients with SSc. Therefore, the objective of this study was to investigate the association of functional capacity and physical activity with arterial stiffness in patients with SSc.

Determinants of Six-Minute Walk Test Performance in Women with Systemic Sclerosis.

Objectives: The aim of this study was to investigate the determinants of six-minute walk test (6MWT) distance in women with systemic sclerosis.

Methods: In this cross-sectional study, 36 women with systemic sclerosis were assessed using the Medsger Systemic Sclerosis Severity Scale (MSS), modified Rodnan Skin Score (mRSS), Health Assessment Questionnaire (HAQ), University of California Scleroderma Clinical Study Consortium Gastrointestinal Tract Scale, quadriceps strength measurement, Milliken Activities of Daily Living Scale (MAS), and International Physical Activity Questionnaire. The 6MWT was performed to assess the participants' functional capacity and examine factors affecting functional capacity.

Comparison of physiological responses after incremental shuttle walking test and 6-minute walk test in patients with systemic sclerosis.

Background: The 6‑minute walk test (6MWT) is a commonly used to evaluate exercise capacity in patients with systemic sclerosis (SSc), but there was no study using the incremental shuttle walking test (ISWT) for assessing exercise capacity and comparing the patient's cardiorespiratory responses to these tests. The aim was to investigate the usability and determinants of the ISWT in patients with SSc and compare the physiological responses after the ISWT and 6MWT.

Methods: A total of thirty four female patients with SSc were included.

Validity and reliability of the Turkish version of the Multidimensional Dyspnea Profile in outpatients with respiratory disease.

Background/aim: Dyspnea is the subjective feeling of breathing discomfort, which is a significant problem for patients with heart and respiratory disease and also an important determinant of exercise tolerance, quality of life, and mortality in various diseases. Most of the scales are not enough to investigate the multidimensional effects of dyspnea; therefore, the Multidimensional Dyspnea Profile (MDP) was developed and validated in many languages. This study aimed to translate and culturally adapt the MDP into Turkish and investigate the psychometric properties of this adapted version in outpatients with respiratory disease.
