“…In fact, we observed a high coupling between Sha-Cal Inv/Eve and Sha-Cal Add/Abd in the Ctrl group and PwDM_noNP group. These observations differ from the data published by Pohl et al (2007), who only found a strong correlation during running but not during walking. Another plausible explanation for this lack of shank internal rotation in the PwDM_NP, next to the altered segmental kinematics during swing, may be a co-contraction of tibialis anterior and gastrocnemius during loading response.…”

“…The strong correlation reported by Pohl et al (2007) between rearfoot frontal plane motion (Sha-Cal Inv/Eve) and forefoot transverse plane motion (Cal-Met Add/Abd) was not observed in our study. Defining the aetiology of this discordance is not straightforward; however, potential influencing factors may be the considerable higher age of the Ctrl group in the current study as well as the difference of segmental modelling.…”

“…Based on previous publications (Pohl et al, 2006(Pohl et al, , 2007, it was decided to analyse the coupling between four intersegment rotations: 1) Sha-Cal Inv/Eve: Sha-Cal Add/Abd, 2) Sha-Cal Inv/Eve: Cal-Met DF/PF, 3) Sha-Cal Inv/Eve : Cal-Met (Inv/Eve), and 4) Sha-Cal Inv/Eve : Cal-Met Add/Abd. Correlation coefficients (r) greater than 0.7 (or less than −0.7) were considered to represent a strong coupling between two segmental rotations.…”

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.

“…Coupling motions between adjacent foot and ankle segments of healthy subjects have been studied [Chang 2008, Eslami 2007, Ferber 2011, Fowler 2009, Pohl 2007. However, several active and passive foot and ankle structures such as the leg tendons and plantar fascia cross multiple joints and attach non-adjacent segments.…”

Excessive foot pronation during static standing, walking and running has been reported as a contributing factor for the development of medial tibial stress syndrome (MTSS). The motion of foot pronation consists of hindfoot and forefoot motion. However, no previous studies have investigated forefoot and hindfoot kinematics during walking and running in subjects with MTSS. The current study sought to compare hindfoot and forefoot kinematics between subjects with and without MTSS while walking and running. Eleven subjects with MTSS and 11 healthy controls (each group containing 10 males and one female) participated in the current study. Segment angles of the hindfoot and forefoot during walking and running barefoot on a treadmill were recorded using three‐dimensional kinematic analysis. An independent t‐test was used to compare kinematic data between groups. Subjects with MTSS exhibited significantly greater hindfoot eversion and abduction (p < 0.05) during walking and running than subjects without MTSS, significantly greater forefoot eversion and abduction (p < 0.05) during walking, and significantly greater forefoot abduction during running (p < 0.05). Hindfoot and forefoot kinematics during walking and running were significantly different between subjects with and without MTSS. For prevention and rehabilitation of MTSS, it may be important to focus on not only hindfoot but also forefoot kinematics during both running and walking. © 2019 Orthopaedic Research Society.
