Hand-Arm Vibration Exposures in Male Drummers: A Cross-Sectional Study

Area of Science:

• Occupational Health
• Musculoskeletal Disorders
• Vibration Science

Background:

• Hand-arm vibration (HAV) exposure is linked to carpal tunnel syndrome (CTS), a common playing-related musculoskeletal disorder (PRMD) in drummers.
• Previous studies assessed HAV exposure for short drumming durations; realistic playing conditions require further investigation.

Purpose of the Study:

• To quantify HAV exposure in drummers under typical playing conditions.
• To compare measured HAV exposure levels against established occupational health limits.

Main Methods:

• A cross-sectional study involving 12 male drummers playing three songs.
• HAV exposure was recorded using a triaxial accelerometer over a mean set duration of 12 minutes.
• Daily vibration exposure 8-hour energy equivalent values [A(8)] were calculated and compared to ACGIH AL and TLV.

Main Results:

• Mean A(8) values significantly exceeded both the ACGIH Action Limit (AL) and Threshold Limit Value (TLV) for both left (8.5 m/s2) and right (10.1 m/s2) hands.
• All participants exceeded the AL in at least one hand, with 11 exceeding it in both.
• Nine participants exceeded the TLV in both hands.

Conclusions:

• Drummers' HAV exposure during realistic playing conditions likely contributes to CTS and other PRMDs.
• Findings underscore the need for strategies to mitigate vibration exposure and reduce PRMD risk in this population.
• Further research should explore diverse playing scenarios, genres, and demographics to refine understanding.
