Impact of Perceived Safety and Barriers on Physical Activity Levels in Community-Dwelling Older Adults During the COVID-19 Pandemic in Singapore: A Cross-Sectional Mixed Methods Study.

This descriptive cross-sectional mixed methods study conducted in Singapore aimed to describe community-dwelling older adults' differences in physical activity (PA) based on perceived safety to exercise, barriers to PA, and preferred modes of PA during a pandemic. Out of 268 older adults, 25.4% felt unsafe to exercise during the pandemic.

Factors influencing fear of falling in community-dwelling older adults in Singapore: a cross-sectional study.

Background: Fear of falling (FoF) has far-reaching implications including activity restriction, functional decline and reduced quality of life. It is a common consequence of falls but may be present even in non-fallers. This study aimed to determine the factors associated with FoF in a segment of Singapore's community-dwelling older adults.

Does the multidimensional grading system (BODE) correspond to differences in health status of patients with COPD?

Study Objectives: To verify whether and to what extent the body mass index, airflow obstruction, dyspnea, and exercise capacity (BODE) index correlates with a disease-specific index of health status in patients with COPD.

Design: Cross-sectional study.

Setting: University-affiliated hospital.

Comparison of different exercise tests in assessing outcomes of pulmonary rehabilitation.

Introduction: Common modalities of clinical exercise testing for outcome measurement after pulmonary rehabilitation (PR) include walk tests, progressive cycle ergometry, and cycle endurance testing. We hypothesized that patients' responses to PR, as measured by those 3 tests, are differentially correlated, and we designed a study to investigate the tests' capacity to detect changes after PR.

Methods: We prospectively tested 37 male patients with stable chronic obstructive pulmonary disease who completed a comprehensive 6-week PR program that included supervised exercise training that emphasized steady-state lower-limb aerobic exercise.
