Identification of gait stability indices for the rehabilitation follow-up of people with transtibial amputation: a preliminary study
Resuming activities of daily living after a lower limb amputation represents a challenge, especially because of the high risk of falling. Thus, rehabilitation initially focuses on stability. Despit..
Definition of an optimal model based on segments' contribution for the estimation of the acceleration of the center of mass in people with lower-limb amputation
In the context of rehabilitation of people with amputation, gait analysis provides information about gait alterations. In that perspective, the body center of mass (BCoM) trajectory, or its derivat..

Systematic review of studies examining transtibial prosthetic socket pressures with changes in device alignment
Suitable lower-limb prosthetic sockets must provide an adequate distribution of the pressures created from standing and ambulation. A systematic search for articles reporting socket pressure changes in response to device alignment perturbation was carried out, identifying 11 studies. These were then evaluated using the American Academy of Orthotists and Prosthetists guidelines for a state-of-the-science review. Each study used a design where participants acted as their own controls. Results were available for 52 individuals and 5 forms of alignment perturbation. Four studies were rated as having moderate internal and external validity, the remainder were considered to have low validity. Significant limitations in study design, reporting quality and in representation of results and the suitability of calculations of statistical significance were evident across articles. Despite the high inhomogeneity of study designs, moderate evidence supports repeatable changes in pressure distribution for specific induced changes in component alignment. However, there also appears to be a significant individual component to alignment responses. Future studies should aim to include greater detail in the presentation of results to better support later meta-analyses
Upper mantle anisotropy of the Borborema Province, NE Brazil: Implications for intra-plate deformation and sub-cratonic asthenospheric flow
Susceptibilite et fabrique magnetiques des granites panafricains dans les unites internes de la chaine des dahomeyides au Togo : Cas des granites de Sihime et de glito
Les fabriques contemporaines de la mise en place des granites panafricains de SihimĂ© et de Glito dans l’unitĂ© structurale de la pĂ©nĂ©plaine bĂ©nino-togolaise des Dahomeyides au Togo (unitĂ©s internes des Dahomeyides), sont Ă©tudiĂ©es par la technique de l’anisotropie de la susceptibilitĂ© magnĂ©tique (ASM). La susceptibilitĂ©Â Â magnĂ©tique Km varie de 86,4 ÎĽSI Ă 213 ÎĽSi dans le pluton de SihimĂ© et de 45,87 ÎĽSi Ă 2455,76 ÎĽSI dans le pluton de Glito. Les foliations sont majoritairement orientĂ©es NE-SW (N 35° Ă N 53°) avec un pendage moyen (> 59°) Ă fort vers le NW ou vers le SE respectivement dans les parties Ă l’Ouest et Ă l’Est du pluton de SihimĂ©. Ces foliations sont submĂ©ridiennes (NNW-SSE Ă N-S) avec un pendage faible Ă moyen au coeur du pluton et un pendage fort Ă ses extrĂ©mitĂ©s Est et Ouest. Les linĂ©ations sont gĂ©nĂ©ralement Ă plongement faible Ă moyen et sont concordantes aux mesures prises sur le terrain. Les mesures d’ASM montrent que le pluton de SihimĂ© est entièrement paramagnĂ©tique par rapport Ă celui de Glito qui a un comportement mixte para- et ferromagnĂ©tique avec une dominance du comportement paramagnĂ©tique.Mots clĂ©s : GranitoĂŻdes, Anisotropie de la susceptibilitĂ© magnĂ©tique (ASM), ChaĂ®ne Panafricaine des Dahomeyides, Togo.Magnetic susceptibility and fabric of pan-african granites Within the internal units from the Dahomeyide belt in Togo: Case of the sihime and glito granitesAnisotropy of magnetic susceptibility (AMS) studies were carried out within panafrican granitic intrusions (Sihime and Glito) which outcrop in the benino-togolese structural unit or the so-called internal structural units from the Dahomeyide belt in Togo. The mean magnetic susceptibility Km is ranging from 86,4 ÎĽSI to 213 ÎĽSi in the Sihime intrusion and from 45,87 ÎĽSi to 2455,76 ÎĽSI in the Glito ones. The magnetic foliations are mainly NW-SE trending with a medium to steep northwestern ward dip. Near the eastern and western edges of the Sihime pluton the folations are southeast dips. In the Glito intrusion, the foliations become NNW-SSE to N-S with generally medium westward dip. Magnetic lineations display generally shallow to medium plunges and parallel trending with the foliations. Magnetic susceptibility (Km) values obtained in the Sihime pluton are typical of dominantly paramagnetic rocks whereas the Glito pluton present the characteristics of both paramagnetic and ferromagnetic granitoids with a prominent paramagnetic signature.Keywords : granitoids, Anisotropy of magnetic susceptibility (AMS), Panafrican Dahomeyide Belt, Togo. Â
