Digital Dance for People With Parkinson's Disease During the COVID-19 Pandemic

The following feasibility outcome measures were assessed: (a) Technical and safety issues, (b) Compliance and motivation, (c) Self-assessed improvement in physical function, wellbeing and cognitive function and (d) The importance of dance as an artistic and creative activity.

Each feasibility outcome measure was assessed via a 5-point Likert scale ranging from (1=very unsatisfactory, 5=very satisfactory), (1=not motivated, 5=very motivated), (1=noticeable worsening, 5=noticeable improvement) or (1=not meaningful, 5=very meaningful). Furthermore, each feasibility outcome measure had an open-ended question connected to it in order to capture any details related that feasibility domain. Two open-ended questions regarding positive and negative aspects of digital dancing were also included.

For each feasibility outcome measure, a criterion of success was developed in order to judge the the success rate of these feasibility outcome measures.

Severity of depression and anxiety symptoms measured by Hospital Anxiety Depression scale Anxiety score: 0-21 higher score indicate more anxiety Depression score: 0-21 higher score indicate more depression

Two questions from the Mental Fatigue Scale were used to measure mental fatigue (item 3) and recovery (item 4). Answers were given on a 7-point Likert scale.

Two focus group interviews were conducted to examine the broader experience of digital dance for people with PD.
