Guitarists interact with many elements such as music stand, chair and implements for instrument positioning in order to accomplish their artistic activity. Regarding auxiliary implements for guitar positioning, it has been recognized, that in addition to providing a better accessibility and a simpler interaction with the musical instrument, it’s necessary to analyze their characteristics and their relationship with the postural variations in musicians to identify possible risk factors and establishing new conditions to prevent them.
This paper aims to describe a postural analysis of three existing auxiliary implements as the base for generating design parameters of a new device for guitar positioning.
To carry out the postural evaluation, guitarists were asked to play a fingering exercise specially designed for this study. They were video recorded in three different angles simultaneously. Afterwards, all videos were synchronized and divided in photograms in order to apply the Rapid Entire Body Assessment (REBA), which was useful as a diagnostic test to identify higher risk postures. Subsequently, the angles of the above-mentioned body segments were estimated using the 3DSSPP software.
