Using an Ergonomic Chinrest With or Without Shoulder Rest During Violin Playing: a Feasibility Study

Ergonomics Clinical Trial

Official title:
Usability and Acceptability of an Ergonomic Chinrest With or Without Shoulder Rest During Violin Playing: a Feasibility Study

Clinical Trial Summary

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.

Clinical Trial Description

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. When this study was initiated, we aimed at a sample size of 10-12 as a rule of thumb for a pilot/feasibility study. However, due to the corona pandemic and the many national restrictions including keeping distance, seeing only a few people, getting tested for the virus and staying at home, if possible, this number could not be reached. Even though the study was planned to include more participants the result from this small study is pointing in one direction, which is supported in a previous study as well. ;
