These are more papers for my boss so I can try to keep him sweet! Would appreciate if anyone could get them as I can't.
Willson, J. D., Ireland, M. L., Davis, I. M. 2006. Core strength and lower extremity alignment during single leg squats. Medicine & Science in Sports & Exercise 38: 945-952
Earl, J. E., Monteiro, S. K., Geiser, C. F., Alexander, P. T. 2007. Reliability and validity of a 2-d approach to assessing frontal plane dynamic alignment of the lower extremity. Journal of Orthopedic & Sports Physical Therapy 37: A1-A19
Willson, J. D., Davis, I. 2007. Utility of the frontal plane projection angle of the knee during single leg squats. Journal of Orthopedic & Sports Physical Therapy 37: 19-A20
I think the second and third only come as abstracts but my boss is convinced otherwise!
Thanks, Nx
