Effects of different violin playing techniques on workload in forearm and shoulder muscles

The user experience of violinists playing with a novel ergonomic chinrest: An evaluation on motivation, usage behaviour, usability and acceptance

BACKGROUND

This study focuses on the user experience of a novel developed ergonomic chinrest (EC), customised to accommodate the individual violinist's anthropometry and playing style. The EC was recently tested for biomechanical effect, but the violin player's motivation, usage behaviour, usability and acceptability may be equally important.

OBJECTIVE

To explore the user experience of violinists who used the novel EC with a low shoulder rest for two weeks. Through that experience, we wanted to learn about the potential user barriers and facilitators related to their motivation, usage behaviour, usability, and acceptability, when trying a new product.

METHODS

Thirty-eight professional violinists participated and evaluated motivation, user behaviour, usability and acceptance using a 5-point Likert scale and open-ended questions.

RESULTS

Participants showed high motivation hoping to improve posture, reduce muscle tension and enhance performance. Usage behaviour was also high, while product appearance, adjustment time, and sound impact were negatively evaluated. However, 37% planned to continue to use EC after the study.

CONCLUSION

Participants showed high motivation and usage behaviour but faced challenges with product appearance, adjustment time, and sound impact compared to their usual chinrest. Incorporating user feedback and addressing design and usability challenges can enhance the user experience.

Measuring the usability of a novel ergonomic chinrest during violin playing: A feasibility study

BACKGROUND

Playing the violin often requires a rotated and lateral flexed neck, leading to potential neck and shoulder problems. An ergonomic chinrest (EC) with or without a shoulder rest (SR or WSR) may enhance neutral neck positioning, but the feasibility of the EC needs to be studied.

OBJECTIVE

Our goal was to evaluate the usability of the EC for a two-week familiarisation period, including aspects such as playing performance, comfort level, and emotional response (e.g., feelings about using the product) among a group of violinists.

METHODS

A one-arm feasibility study was conducted to assess the feasibility of violinists playing with EC every day for two weeks. Six violinists who usually played with SR were included and asked to divide their daily playing time equally between SR and WSR. Feasibility outcomes were measured as adherence (days), compliance (playing hours per day) and usability (5-point Likert scale and open-ended questions). Compliance was achieved with a minimum of 25% playing time.

RESULTS

Daily violin playing with EC showed high adherence of 89.3%. Compliance with the 25% play time criterion was met for SR, but not for WSR. Low playing performance (median 45.8 points difference), long confidence time (two violinists failed to reach a confidence level) and mainly negative feedback (26 out of 33 comments) were found in WSR compared to SR.

CONCLUSIONS

The feasibility of playing WSR was low and negatively impacted playing performance. As a result, a larger-scale study will only evaluate the EC with SR due to greater feasibility.
