“…The same criticism as mentioned earlier can be used here as these were case series with only 2 and 3 subjects. In the study of Sanders et al (2000), the authors also conclude that effective techniques to accommodate time related stump volume fluctuations have a greater impact on maintaining consistent interface stress distributions than do alterations in cadence or componentry. Pressure measurement research in prosthetics seems to be a big challenge for future researchers.…”

A review was performed of the literature of the last eleven years (1990)(1991)(1992)(1993)(1994)(1995)(1996)(1997)(1998)(1999)(2000) with the topic: "clinical use of instrumented gait analysis in patients wearing a prosthesis of the lower limb". To this end a literature search was performed in Embase, Medline and Recal. Forty-five (45) articles were identified for study from which 34 were reviewed. The reviews were divided into five subtopics: 1) adaptive strategies in gait (12 studies); 2) the influence of different parts of the prosthesis on gait (12 studies); 3) pressure measurements in the socket in gait studies (4 studies); 4) the influence of the mass of the prostheses on gait (5 studies); 5) energy considerations in gait (2 studies).A considerable part of the studies concerned the adaptive strategies of the amputee in walking and running and the evaluation of different prosthetic feet. All aspects and outcomes were reviewed concerning the clinical relevance. ConclusionInstrumented gait analysis in prosthetics provides better insights and knowledge of the different adaptive mechanisms of the body in walking with a prosthesis. Most instrumented gait studies are done in a gait laboratory. This is not comparable with the patient's home or work situation. Instrumented gait studies assess only

“…Evidence in the literature has demonstrated that localized pressures within the socket vary substantially with movement and, therefore, might be used to determine activity type and stepping [20][21][22][23][24][25][26]. In addition, because the pressure measured is related to socket-residual limb movement, one might expect that a measure of wearing times could be determined from this pressure.…”

“…Changes in interface pressure with prosthetic alignment [20][21], activity type [22], time of day [23], change in limb components [24], wedging [25], and dependence on individual prosthesis fit [26] have all been demonstrated. This evidence suggests that pressure measurement could provide the information necessary to determine the activity being undertaken, allowing discrimination between different movement patterns.…”

“…Importantly, analysis of the pressure could also allow determination of wearing times. Measurement of the pressure has been accomplished by numerous research groups [20][21][22][23][24][25][26][27][28][29]. However, direct measurement at the residual limb-socket interface requires socket modification and may lead to interference between the socket and residual limb.…”

Abstract-Prostheses are prescribed to restore the mobility of people with amputated lower limbs. Monitoring the prosthesis wearing times and physical activity of prosthesis users would provide invaluable information regarding rehabilitation progress and suitability of the prosthesis. The validation of a method to determine wearing times and physical activity state, as well as strides taken, of amputees wearing suction suspension sockets is reported. Eight participants with transtibial amputation were fitted with custom-made suction sockets. Analysis algorithms were used to automatically characterize physical activity based on the pressure at the socket's relief valve. The algorithms were validated in a laboratory-based protocol that included walking, stair climbing, standing, sitting, donning, and doffing. Intraclass correlation coefficient (2,1) values of >0.98 were achieved with mean differences of -2.0%, 0.3%, 1.3%, and 0.7% for agreement between "off," "static," and "dynamic" times and stride count, respectively, as determined by the analysis algorithms and a concurrent video analysis. This study demonstrates that an interpretation of the pressure at the pressure-relief valve of suction suspension sockets can be used to determine wearing times and activity state.

“…Patients' rejection to the use of prosthesis propels the study of new techniques to make their use more natural (Ferris et al, 2012;Laferrier and Gailey, 2010;Rusaw and Ramstrand, 2010;Sanders, Zachariah, Baker, Greve and Clinton, 2000;Zhou et al, 2015). Changes in design, type of actuators, sensors and control techniques enable the improvement of commodities and functionality of prosthesis (Cherelle et al, 2014(Cherelle et al, , 2012Shultz et al, 2016;Zheng and Shen, 2013).…”

En el Centro de Diseño y Metrología del SENA– CDM se ha detectado que la población en condición de discapacidad de miembros inferiores representa un desafío técnico y tecnológico en la recuperación de las condiciones normales de la marcha, puesto que se requieren intervenciones costosas o elementos que ayuden al desplazamiento de estas personas, como bastones, sillas de ruedas, muletas u otros implementos que sirvan de soporte y faciliten la rehabilitación del paciente. Es importante tener en cuenta que hay dudas acerca de si las prótesis existentes en el mercado suplen las necesidades económicas y de funcionalidad de cada paciente. Con esta investigación se pretende implementar una prótesis transtibial, a fin de mejorar algunas condiciones de la marcha del paciente. Colombia no cuenta con muchas entidades que diseñen y fabriquen los elementos que componen una prótesis. Por tal razón y porque en el SENA, específicamente en el Centro de Diseño y Metrología- CDM, hace aproximadamente cinco años se viene trabajando en el diseño y adaptación de ortesis y prótesis, pero con componentes importados, se quiere diseñar e implementar una articulación de tobillo para amputación transtibial, haciendo uso del recurso humano y tecnológico disponible en el país, y así, poder desarrollar un sistema con manufactura propia y 100 % SENA, que cumpla con las características de funcionalidad y ergonomía para los pacientes con dicha discapacidad. Este artículo científico original recopila la Información más relevante sobre un tema que afecta nuestra sociedad. Aquí se analizan diferentes fuentes bibliográficas descritas en la literatura existente. Con ellas creamos las etapas necesarias para la redacción del artículo definiendo los objetivos de la revisión, haciendo la búsqueda más relevante de la bibliografía y organizando la información de acuerdo con mapas mentales para redactar el artículo.
