简要总结
A one-arm feasibility study was conducted to test if violinists would accept to play with an identified ergonomic chinrest (EC) with the brand name Kréddle every day for two weeks. Every day the participants had to divide their total playing time equally between EC+ (ergonomic chinrest with shoulder rest) and EC- (ergonomic chinrest without shoulder rest) each day.
详细描述
This study is testing the feasibility (usability and acceptability) of a two-week familiarization period where violinists usually playing with a shoulder rest had to play their violin with an ergonomic chinrest (EC) with (EC+) and without a shoulder rest (EC-).
Primary outcomes were compliance, adherence, usability and acceptability of the familiarization period.
Prior the familiarization period each violinist received the chinrest (Kréddle) and a shoulder rest (Kun Super rest violin 4/4) and had to follow instructions given through three introduction videos.
The included violinists received a web questionnaire (QA) before and after the familiarization period. This period is unsupervised with the EC (ergonomic chinrest). Every day each violinist should equally divide their total playing time between playing without shoulder rest (EC-) and the other half with the shoulder rest (EC+) with the EC. A diary was answered each day containing different questions in regard to playing hours and usability.
The reporting in this study adheres to the CONSORT 2010 extension for pilot and feasibility trials.

结局指标
主要结局
Acceptability
时间窗: Two weeks
Every day each violinist was encouraged to write feedback in the diary about using EC+, EC- and about the intervention. The descriptions and comments were categorized into comments about using EC-, EC+ or general comments; the response was grouped as positive or negative feedback.
Usability
时间窗: Two weeks
Self-reported information about the usability of the EC- and EC+ was obtained by asking questions about perceived performance, comfort, and sound experience, as well as adjustment and confidence level. Furthermore, if the instructions videos given prior to the familiarization period were usable.
Compliance
时间窗: Two weeks
Compliance for playing with EC- and EC+ was reached if the violinist managed to play minimum 25% out of total playing time with each of both settings. If compliance was \<25% it was considered that it would be a problem to use the setting
Adherence
时间窗: Two weeks
Adherence to the protocol was recorded from the self-administrated two-week diary. The violinist had to answer a small questionnaire and play each day with one of the settings. Adherence is counted as numbers of days played with the different settings out of the two weeks given.
次要结局
- Neck movement was recorded by the device called ViMove.(Two weeks)
