OBJECTIVE: To propose design requirements for new supports for guitar positioning, based on postural assessment, anthropometric criteria, self-efficacy and comfort perception.
METHODS: Nine healthy Classical Guitar students were recruited. A postural assessment was undertaken using REBA, and 3DSSPP software with three different supports for guitar positioning. After the use of each support, a questionnaire about self-efficacy and comfort perception was completed by the participants.
RESULTS: The higher scores of risk and a significant difference (ANOVA, p =≤05) regarding the left leg elevation were found with footstool usage. However, this one was identified by participants as the best support in terms of self-efficacy and comfort assessment.
CONCLUSIONS: To improve performance and prevent physical injuries for guitarists, there is a need for designing guitar positionings supports based on ergonomics principles. This paper proposes eleven guidelines for designing these supports.
