Hi all,

Thanks to all who replied to my request. It was great to get such a rapid
response. My original posting was

The paper I was after was

Holden, J. P., Stanhope, S. J. The Effect of Variation in the Knee Center
Location Estimates on Net Knee Moments. Gait & Posture 1998; 7:1-6.

However, some other very good articles were also suggested, and I have
found some other papers as well. These have been and will be very useful in
assessing the accuracy of the inverse dynamic method. These are

the moments measured by an isokinetic dynamometer, J. Biomechanics, 21(1),
5-12.
