Inter-rater and intra-rater reliability of the Brief-BESTest in people with chronic obstructive pulmonary disease.

Objective:: To investigate the inter-rater and intra-rater reliability of the Brief Balance Evaluation System Test (Brief-BESTest) in people with chronic obstructive pulmonary disease and its correlation between the Brief-BESTest score and lung function, functional exercise capacity, functional lower limb strength, and fear of falling.

Design:: Prospective, single-group, observational study.

Setting:: Outpatient pulmonary rehabilitation program.

Short-form Sun-style t'ai chi as an exercise training modality in people with COPD.

The aims of the study were to determine the effect of short-form Sun-style t'ai chi (SSTC) (part A) and investigate exercise intensity of SSTC (part B) in people with chronic obstructive pulmonary disease (COPD). Part A: after confirmation of eligibility, participants were randomly allocated to either the t'ai chi group or control group (usual medical care). Participants in the t'ai chi group trained twice weekly for 12 weeks.
