Dear all,
While there has been a huge amount of published research dealing with all
aspects of cervical activity, I've found very little that can be used for
specific (and quantitative) evaluation of injury risk associated with
cervical axial rotation.
In particular, have found only one paper that makes reference both to
rotation ROMs and uses times of exposure to these ROMs as injury criteria
(based on Swedish workers comp. data). Unfortunately for me, the paper is
Swedish; and I have no idea how to get a copy of it (library was not able to
help). The paper is:
Andersson, G. et al (1983) [English title: Model for evaluation of injuries
in the neck and shoulders according to the Swedish National work injury
insurance]. Lakartidningen, 80, 3186-3190.
I found the above reference cited in Eklund et al (1994) Head posture
measurements....etc. Ergonomics, 37(4), 623-639.
If anyone could please send a PDF or Word version of the paper it would be
very much appreciated!!
Secondly, are there any other published sources of such information. Quite a
few papers have provided range classifications (e.g., neutral, non-neutral)
but few provide any quantitative evidence-based rationale for these
classifications, nor do they give any indication of exposure thresholds -
i.e., how long must one be exposed to a "non-neutral" range (e.g. >15 deg)
to be at significant injury risk (even without considering
interactions....)?
Just a reminder...all the above relates to cervical axial rotation (not
flex/ext'n). However, any similar info on trunk rotation or lateral flex'n
(esp. if seated) also appreciated.
TIA,
Max.
