Preoperative gait characterization of patients with ankle arthrosis

Rear-foot, mid-foot and fore-foot motion during the stance phase of gait

“…This marker set was successfully tracked with standard full body TV camera configuration, thus saving the examiners from special camera arrangements and system calibration procedures [26,28,47]. In addition, not only is the marker set proposed here compatible with our original protocol for lower limb kinematics [48], but also the ability of the stereophotogrammetric system to track successfully both relevant marker sets was demonstrated in a few trial tests.…”

The effect of low-mobile foot posture on multi-segment medial foot model gait kinematics

“…Subsequent studies have reported significant kinematic differences between participants with ''normal'' foot posture and those with clinical pathologies [14][15][16], suggesting that MSFMs have the ability to differentiate between ''normal'' and ''abnormal'' gait.…”

Consequences of Ankle Inversion Trauma: A Novel Recognition and Treatment Paradigm

“…The vast majority of post-traumatic ankle OA research has been focused on patient-oriented evidence and the results consistently show, regardless of the scale used, that those with post-traumatic ankle OA have greater levels of self-reported disability relative to age matched controls. (Horisberger, Hintermann, & Valderrabano, 2009a;Hubbard, Hicks-Little, & Cordova, 2009b;Khazzam, Long, Marks, & Harris, 2006;Messenger, Anderson, & Wikstrom, 2011;Valderrabano et al, 2007;Valderrabano et al, 2006b) Clinical-oriented evidence shows similar impairments as those associated with acute LAS and CAI. Specifically, decreases in ankle muscle strength and increased mechanical stiffness have been observed relative to age matched controls.…”

“…plantar pressure distributions and COP displacements) have been reported to be altered and/or increased (Horisberger et al, 2009a;Hubbard et al, 2009b;Messenger et al, 2011) and walking gait velocity, cadence, and stride length are all reduced in those with ankle OA. (Khazzam et al, 2006;Valderrabano et al, 2007) Most recently, Messenger et al (Messenger et al, 2011) illustrated that post-traumatic ankle OA alters gait initiation relative to uninjured age-matched controls. This evidence further illustrates that the long term sequela of LAS are global in nature and can negatively influence the central nervous system.…”
