There is an ongoing debate regarding the advantages and harms of different running striking patterns. The purpose this study was to explore kinematic differences between with a midfoot- rearfoot (RFS) pattern.Multi-segment foot kinematics 12 students were assessed while barefoot at 3.3 m/s (±10%) using passive optoelectronic motion analysis system. Participants performed multiple trials landing on midfoot. Comparison waveforms one-dimensional statistical parametric mapping (1DSPM) (paired...

Ankle arthrodesis is considered to be an optimal treatment strategy relieve pain during walking in patients with isolated, end-stage tibiotalar osteoarthritis. The aim of this study was investigate the post-operative effect on ankle and foot joint biomechanics. We included both (

Patients with isolated ankle osteoarthritis (OA) often demonstrate disturbed biomechanics during walking. Clinicians believe that this triggers the distal foot joints to compensate these altered and are consequently subjected degenerative joint diseases due overuse.Do patients OA differ from those without in terms of (1) kinematics (2) kinetics as measured using three-dimensional (3-D) gait analysis? (3) Do compensatory strategies their Chopart, Lisfranc, or first metatarsophalangeal...

Abstract Introduction Haemophilic ankle arthropathy due to repeated joint bleeds often leads altered gait in adult patients with haemophilia. Aim To investigate the association between clinical features and blood‐induced damage scored using MRI findings haemophilic arthropathy. Methods This observational study investigated 48 ankles of 24 severe haemophilia (median age 33 years). Blood‐induced was by an experienced radiologist International Prophylaxis Study Group (IPSG‐)MRI score which...

A comprehensive insight into the effects of subtalar- and mid-tarsal joint osteoarthritis on lower limb's biomechanical characteristics during walking is lacking. Our goal was to assess kinematics kinetics compensatory mechanisms in patients with subtalar osteoarthritis.Patients symptomatic radiographically confirmed (n = 10) an asymptomatic control group were compared. Foot stance phase quantified using a four-segment foot model.During pre-swing phase, tibio-talar range motion sagittal...

The foot seems to demonstrate considerable power absorption and generation characteristics during running. These have been mainly accounted the mechanics of ankle joint, however, evidence suggests that joint kinetics overestimated by single-segment models. scope present study was estimate energetics ankle-, chopart-, lisfranc- hallux heel-strike Power occuring at different segments seven asymptomatic adults modelled using a four-segment kinetic model. Participants ran barefoot with an...

Abstract Introduction Patients with haemophilia (PwH) often prefer shod walking over barefoot as footwear offers ankle joint stability and comfort during gait. Yet, the biomechanical mechanisms contributing to latter remain poorly understood. Aim To explore effect of shoes on functioning foot complex in PwH without haemophilic arthropathy determine amount loading walking. Methods We analysed data (n = 5) severe 17) a control group 17). During 3D gait analysis, four‐segment kinetic model was...

Ankle cartilage damage due to repeated joint bleeds often leads altered gait in adult patients with hemophilia. It is therefore of clinical importance develop an understanding the biomechanical features hemophilia and without blood-induced age-matched control subjects. We recruited a group (n = 17), (PwH) ankle (PwH_NoCartDam , n 5) PwH severe (PwH_CartDam 19). collected three-dimensional analysis data following outcome variables ankle, Chopart first metatarsophalangeal (MTP 1) joints: range...

Abstract Aim To compare foot joint kinetics and energetics in male paediatric boys with without blood‐induced ankle destruction to these of matched control groups. Methods A cross‐sectional study was conducted which 3D gait analysis data were collected from thirty‐five children (6‐21 years) severe or moderate haemophilia twenty‐six typically developing boys. Structural integrity the tarsal joints all haemophilic patients assessed using IPSG‐MRI scale. All participants walked barefoot while...

A comprehensive insight into the in vivo foot kinetics of patients with posterior tibial tendon dysfunction (PTTD) is lacking to support clinical decision making. Our goal was study how PTTD alters kinetic and kinematic characteristics ankle a special focus on midfoot joints. Multisegment joint kinematics were compared based Rizzoli Foot Model inversed dynamics between control group (n = 25), Stage II 21) III 4) over entire stance phase. Compared controls, mean decrease power generation 1.3...

Abstract Background Application of in‐shoe multi‐segment foot kinematic analyses currently faces a number challenges, including: (i) the difficulty to apply regular markers onto skin, (ii) necessity for an adequate shoe which fits various morphologies and (iii) need repeatability throughout repeated measure condition. The aim this study therefore was design novel magnet based 3D printed measurements while using accordingly adapted modified shoes specific model. Methods Multi‐segment...

Foot structure and kinematics have long been considered as risk factors for foot lower-limb running injuries. The authors aimed at investigating joint kinetics to unravel their receptive propulsive characteristics while barefoot, both with rearfoot midfoot striking strategies. Power absorption generation occurring different joints of the in 6 asymptomatic adults were calculated using a 3-segment 4-segment kinetic model. An inverse dynamic approach was used quantify mechanical power. Major...

Background We aimed to determine the center of pressure (COP) trajectories and regional differences in natural rearfoot strikers while running barefoot, with a minimalist shoe, traditional shoe. Methods Twenty-two male ran at an imposed speed along instrumented runway three conditions: Metrics associated COP plantar force distribution, captured platform, were compared using one-way repeated-measures analysis variance. Results The forefoot contact phase was found be significantly shorter...

Ankle joint distraction (AJD) has been described to be a valuable joint-sparing alternative arthrodesis or arthroplasty; however, clinical endpoints associated this surgical intervention are lacking. The current case report describes and biomechanical outcome measures of ankle in 14-year-old patient with severe haemophilia A. Because persistent incapacitating pain the poor response conservative invasive treatment options, was performed using an external fixator encompassing two Ilizarov full...
