Résumé / Abstract
Soft tissue artefacts (STA) is one of the main limitations for using motion capture. Foot joint arthrodeses are frequently performed in end-stage osteoarthritis. Tibio-talo-calcaneal (TTC) arthrodesis consists to fuse the joints between the calcaneus, the talus and the tibia together. One may expect that motion recorded during gait between the segments of the calcaneus and the shank would result only from STA. Four subjects who underwent a TTC arthrodesis performed a gait analysis with a modified version of the Rizzoli foot model. Effects of STA found for the shank-calcaneus dorsi-plantar flexion were larger than that reported in previous studies. This might be due to major skin sliding over the calcaneus for these subjects. S tudies assessing subjects with TTC arthrodesis should interpret kinematic data with caution.
