Rl. Blake et Hj. Ferguson, CORRELATION BETWEEN LIMB LENGTH DISCREPANCY AND ASYMMETRICAL REARFOOTPOSITION, Journal of the American Podiatric Medical Association, 83(11), 1993, pp. 625-633
Ten subjects with a known limb length discrepancy were filmed with the
two-dimensional Motion Analysis Foot Trak System(R)1; eight were film
ed running and walking and two were filmed walking only. A control gro
up of ten subjects with no measured limb length discrepancy was filmed
in the same manner (eight walking and running and two walking only).
The calcaneus-to-vertical angle was recorded for the entire stance gai
t cycle (heel contact to toe-off). Analysis of the data between the sh
ort and long side showed a significant difference in calcaneal positio
n between the two sides at midstance, with the longer side being more
everted by 3-degrees or greater than the short side in most cases. The
re was no significant difference in the calcaneus-to-vertical angle at
heel contact between the long and short side. There was no significan
t difference between the calcaneus-to-vertical angles of the right and
left sides of the ten control subjects, either walking or running.
