Perceived Barriers to Physical Activity Among Youth Living in Rural and Urban Canadian Communities: A Nationally Representative Cross-Sectional Study.

Background: We used nationally representative data to explore associations among location of residence (rural/urban) and perceived barriers to physical activity (PA) in Canadian youth.

Methods: We analyzed the 2017 Canadian Community Health Survey, Barriers to Physical Activity Rapid Response data for 12- to 17-year-old youth. Nine items from the survey assessing perceived barriers to PA were combined into 3 barrier domains: resources, motivational, and socioenvironmental.

Intensive care unit clinicians identify many barriers to, and facilitators of, early mobilisation: a qualitative study using the Theoretical Domains Framework.

Question: From the perspective of intensive care unit (ICU) clinicians, what are the barriers to and facilitators of implementing early mobilisation?

Design: A qualitative study using focus groups, with analysis using the Theoretical Domains Framework.

Participants: Physicians, nurses, respiratory therapists and physiotherapists from the ICUs of three university-affiliated hospitals in Montreal, Canada.

Methods: Four focus group meetings were conducted with 33 participating ICU clinicians.

Early rehabilitation reduces the likelihood of developing intensive care unit-acquired weakness: a systematic review and meta-analysis.

Background: Intensive care unit-acquired weakness (ICUAW) is associated with significant impairments in body structure and function, activity limitation, and participation restriction. The etiology and management of ICUAW remain uncertain.

Objective: To estimate the extent to which early rehabilitation interventions (early mobilization [EM] and/or neuromuscular electrical stimulation [NMES]) compared to usual care reduce the incidence of ICUAW in critically ill patients.

Effects of Pressure Support Ventilation May Be Lost at High Exercise Intensities in People with COPD.

Pressure support ventilation (PSV) may be used for exercise training in chronic obstructive pulmonary disease (COPD), but its acute effect on maximum exercise capacity is not fully known. The objective of this study was to evaluate the effect of 10 cm HO PSV and a fixed PSV level titrated to patient comfort at rest on maximum exercise workload (WLmax), breathing pattern and metabolic parameters during a symptom-limited incremental bicycle test in individuals with COPD. Eleven individuals with COPD (forced expiratory volume in one second: 49 ± 16%; age: 64 ± 7 years) performed three exercise tests: without a ventilator, with 10 cm HO of PSV and with a fixed level titrated to comfort at rest, using a SERVO-i ventilator.

Interprofessional Survey of Perceived Barriers and Facilitators to Early Mobilization of Critically Ill Patients in Montreal, Canada.

Objective: Early mobilization is safe, feasible, and associated with better outcomes in patients with critical illness. However, barriers to mobilization in clinical practice still exist. The objective of this study was to assess the knowledge and practice patterns of intensive care unit (ICU) clinicians, as well as the barriers and facilitators to early mobilization.
