“…Adjustment for multiple testing in this study was performed over the set of five test points. This choice can be contested, however, it is a generally accepted approach in explorative studies (Khazzam et al, 2007;Ness et al, 2008). Moreover, a closer look at our data supports this decision, as our significance level (P b 0.01) creates a 'benchmark' where it seems that minimally 30% difference in range of motion is being considered as significant (e.g.…”

“…More recently, 3D multisegment foot models (3DMFMs) emerged allowing the quantification of the mobility of different foot segments during clinical gait analysis (Baker and Robb, 2006;Deschamps et al, 2011). The clinical usefulness of this method with respect to pathomechanical modelling has been underpinned with methodological as well as clinical studies in different patient populations (Deschamps et al, 2012a(Deschamps et al, , 2012bNess et al, 2008). So far, clinical usefulness of this segmental modelling in patients with DM has been explored by two different research groups (Rao et al, 2007;Sawacha et al, 2009).…”

Background: Reduction in foot mobility has been identified as a key factor of altered foot biomechanics in individuals with diabetes mellitus. This study aimed at comparing in vivo segmental foot kinematics and coupling in patients with diabetes with and without neuropathy to control adults. Methods: Foot mobility of 13 diabetic patients with neuropathy, 13 diabetic patients without neuropathy and 13 non-diabetic persons was measured using an integrated measurement set-up including a plantar pressure platform and 3D motion analysis system. In this age-, sex-and walking speed matched comparative study; differences in range of motion quantified with the Rizzoli multisegment foot model throughout different phases of the gait cycle were analysed using one-way repeated measures analysis of variance (ANOVA). Coupling was assessed with cross-correlation techniques. Findings: Both cohorts with diabetes showed significantly lower motion values as compared to the control group. Transverse and sagittal plane motion was predominantly affected with often lower range of motion values found in the group with neuropathy compared to the diabetes group without neuropathy. Most significant changes were observed during propulsion (both diabetic groups) and swing phase (predominantly diabetic neuropathic group). A trend of lower cross-correlations between segments was observed in the cohorts with diabetes. Interpretation: Our findings suggest an alteration in segmental kinematics and coupling during walking in diabetic patients with and without neuropathy. Future studies should integrate other biomechanical measurements as it is believed to provide additional insight into neural and mechanical deficits associated to the foot in diabetes.

We describe a multi-segmented foot model comprising lower leg, rearfoot, midfoot, lateral forefoot, medial forefoot, and hallux for routine use in a clinical setting. The Ghent Foot Model describes the kinematic patterns of functional units of the foot, especially the midfoot, to investigate patient populations where midfoot deformation or dysfunction is an important feature, for example, rheumatoid arthritis patients. Data were obtained from surface markers by a 6 camera motion capture system at 500 Hz. Ten healthy subjects walked barefoot along a 12 m walkway at self-selected speed. Joint angles (rearfoot to shank, midfoot to rearfoot, lateral and medial forefoot to midfoot, and hallux to medial forefoot) in the sagittal, frontal, and transverse plane are reported according to anatomically based reference frames. These angles were calculated and reported during the foot rollover phases in stance, detected by synchronized plantar pressure measurements. Repeated measurements of each subject revealed low intra-subject variability, varying between 0.78 and 2.38 for the minimum values, between 0.58 and 2.18 for the maximum values, and between 0.88 and 5.88 for the ROM. The described movement patterns were repeatable and consistent with biomechanical and clinical knowledge. As such, the Ghent Foot model permits intersegment, in vivo motion measurement of the foot, which is crucial for both clinical and research applications. Keywords: multi-segment foot model; foot and ankle kinematics; gait analysis; Ghent Foot Model Multi-segmented foot models can provide better insight into foot kinematics (and to a less extent segmental foot kinetics) during gait than single segments models. Clinically, they are used to describe and analyze functional characteristics associated with foot impairments. A number of multi-segmented foot models, using either bone pins or surface markers, have been proposed. They vary according to the number of segments and functional unit definition, in the methods of calculating intersegment angles, and in the definition of the neutral foot reference position. 1,2The need exists for a clinically relevant, user-friendly multi-segment foot model that would include the lower leg, hindfoot, midfoot, medial and lateral forefoot, and the hallux, with wide utility to investigate single joint/segment joint dysfunction through to complex foot deformities. Models with <5 segments often can not describe whole foot kinematics. [3][4][5][6][7] In contrast, those with nine segments 8 are not always easily applicable in clinical settings. To our knowledge and based upon a recent review, 2 no such model is currently available.There are two main reasons why a 6 segment model is clinically relevant. First, these segments are examined clinically by physical therapists and podiatrists. The medial arch, formed by the rearfoot (talus), the medial part of the midfoot, and the first ray, plays an important role in foot function during weight bearing activities. 9 Different arch configurations are an intrinsic ris...
