It's a shocker for rockers
(Research paper: Head and neck injury risks in heavy metal: head bangers stuck between rock and a hard bass)Head banging increases the risk of head and neck injury, but the effects may be lessened with reduced head and neck motion, head banging to lower tempo songs or to every second beat, and using protective equipment such as neck braces, finds a study in the Christmas issue published on bmj.com today.
What began in 1968 at a Led Zeppelin concert with fans banging their heads on the stage, has developed into a collection of distinctive styles including the up-down, the circular swing, the full body and the side-to-side.
Anecdotal reports of head banging induced injury include hearing loss, stroke and mild traumatic brain injury, but there has been little formal research into head banging.
Declan Patton and Professor Andrew McIntosh from the University of New South Wales, analysed the injury risk from head banging and examined possible ways to protect against these injuries.
The researchers attended hard rock and heavy metal concerts including Motörhead, Ozzy Osbourne and Skid Row, and identified that the up-down style was the most common head banging technique. They constructed a theoretical head banging model of this popular style to examine the effect the range of head and neck motion has on injury severity. A focus group of ten musicians was used to calculate the average tempo of their favourite head banging songs.
The authors found that there is an increasing risk of neck injury beginning at tempos of 130 beats per minute related to the range of motion in the head banging style....
