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

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 Sihimé et de Glito dans l’unité structurale de la pénéplaine  bénino-togolaise des Dahomeyides au Togo (unités internes des  Dahomeyides), sont étudiées par la technique de l’anisotropie de la  susceptibilité magnétique (ASM). La susceptibilité   magnétique Km varie de 86,4 μSI à 213 μSi dans le pluton de Sihimé et de 45,87 μSi à 2455,76 μSI dans le pluton de Glito. Les foliations sont majoritairement orientées NE-SW (N 35° à N 53°) avec un pendage moyen (> 59°) à fort vers le NW ou vers le SE respectivement dans les parties à l’Ouest et à l’Est du pluton de Sihimé. Ces foliations sont subméridiennes (NNW-SSE à N-S) avec un  pendage faible à moyen au coeur du pluton et un pendage fort à ses extrémités Est et Ouest. Les linéations sont généralement à plongement faible à moyen et sont concordantes aux mesures prises sur le terrain. Les mesures d’ASM montrent que le pluton de Sihimé est entièrement paramagnétique par rapport à celui de Glito qui a un comportement mixte para- et ferromagnétique avec une dominance du comportement paramagnétique.Mots clés : Granitoïdes, Anisotropie de la susceptibilité magnétique (ASM), Chaîne 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 μSI to 213 μSi in the Sihime intrusion and from 45,87 μSi to 2455,76 μSI 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.
