Biomechanical Investigation of Methods of Grasping a Trombone: A Pilot Study

Abstract

Trombonists, like other musicians, are at risk for developing use-related musculoskeletal symptoms. This study investigated an ergonomic aid for playing the trombone, the Neotech Trombone GripTM, which assists a trombonist’s left hand in supporting the instrument. The objective of the study was to investigate effects of this device on the left upper extremity while playing the trombone in comparison to the standard, unaided method of grasping it. Seven trombone players used the grip for two weeks prior to providing objective and subjective data in a laboratory environment. They played a scale and a piece of their choice under four conditions: sitting or standing with or without the device on their trombone. While playing, muscle activity in the trapezius, anterior deltoid, middle deltoid, extrinsic finger flexor, and extrinsic finger extensor muscle groups on the left side of the body were collected. Perceptions on the device using a survey were also assessed. Results indicated a consistent decrease in muscle activity in the finger flexor group when using the device. Smaller, less consistent effects were seen in activity in the trapezius (decrease), finger extensor group (increase), and anterior deltoid (increase) muscles, while using the device. Effects were more pronounced in players with smaller hands (among the group of participants). Most players subjectively found the device beneficial and all would recommend it to other players.
