Summary

A one-day crossover randomised trial was conducted to compare violinists using an ergonomic chinrest (EC) with do-as-usual on muscle activation, kinematics and sound. After two weeks of testing the EC, self-perceived evaluations on comfort, performance, sound, neck alignment and muscle tension were reported in a questionnaire between EC and do-as-usual.

The main question is to answer if:

1. the EC is superior compared to do-as-usual and gives a more aligned neck posture and less muscle tension/dynamic muscle activity
2. the EC is subjectively evaluated as better than do-as-usual regarding self-perceived comfort, performance and sound

Conditions

  • Ergonomics

Interventions

DEVICE

Ergonomic chinrest used with low shoulder rest (EC)

Participants will play the violin using the ergonomic chinrest with a low Kun Super shoulder rest (EC) for two weeks before the test day (crossover study), measuring upper body kinematic and muscle activity. The novel ergonomic chinrest (Kréddle®, Wyoming, US) is fully adjustable to accommodate each violinist's body type and performance style: regarding height, rotation and tilting. The low Super Kun shoulder rest has been adjusted to be in the lowest position for all legs attached to the violin before the violinists received it. All participants was told not to adjust the shoulder rest but adjust the chinrest.
