Feasibility of Dance in People With COPD

Enrollment rate is calculated as a percentage (number of people enrolled/ number of people approached)

Attendance rate is calculated as a mean percentage for the group (number of sessions attended/ number of total sessions)

Participant satisfaction and the perceived benefits were assessed by asking participants to complete a nine-item survey which asked participants to report their level of agreement with statements on enjoyment and perceived improvements or benefits according to a 5-point Likert type scale (1 = strongly agree, 5 = strongly disagree). The questionnaire contained open-ended questions asking participants what they liked best and least as well as what they would change about the intervention.

Adverse events were tracked and the program is considered safe and feasible if no adverse events occurred.

Changes in the distance walked as measured using 6-minute walk test. The farther the distance walked in 6 minutes, the better the functional capacity.

Change in balance from baseline to end of 8-week dance program as measured by Balance Evaluation Systems Test (BESTest). The BESTest consists of 36 items that evaluate balance impairments across six postural control contexts. These six contexts are: biomechanical constraints, stability limits/verticality, anticipatory postural adjustments, postural responses, sensory orientation and stability in gait. Total score of BESTest is 108 points (the item-level score ranges from 0 "severe impairment to 3 "no impairment"), calculated into a percentage score (0%-100%) with the higher score the better the balance.

Change in balance from baseline to end of 8-week dance program as measured by Balance Evaluation Systems Test (BESTest) and Berg balance scale. Berg balance scale comprises a set of 14 simple balance related tasks, ranging from standing up from a sitting position, to standing on one foot. The degree of success in achieving each task is given a score of zero (unable) to four (independent), and the final measure is the sum of all of the scores, with a higher score indicating better balance.

Change in balance confidence from baseline to end of 8-week dance program as measured using the Activities-specific Balance Confidence (ABC) scale. The scale consists of 16 statements on different activities and the participant indicates their level of confidence in doing the activities without losing their balance or becoming unsteady from choosing one of the percentage points on the scale from 0% to 100% with the higher values represent a better balance confidence.

Change in anxiety and depression from baseline to end of 8-week dance program measured using Hospital Anxiety and Depression Scale.The scale consisted of 14 items (seven for anxiety and the same for depression). Each item is a four point (0-3) response category so the possible scores ranged from 0 to 21 for anxiety and 0 to 21 for depression with the lower score is the better outcome

Change in health related quality of life from baseline to end of 8-week dance program measured using the chronic respiratory questionnaire which is an interviewer-administered one that measures both physical and emotional aspects of chronic respiratory disease. The questionnaire is a 7-point modified Likert Scale, consists of 20 items that explore four categories: dyspnea, fatigue, emotional function and mastery. The maximum score possible is 140 and the lowest is 20 with the higher scores indicate better health-related quality of life
