In this research an analysis for improving the fatigue behavior (safety factor of fatigue) non- articular prosthetic foot (SACH) in region (Bolt Adapter).The laser peening was carried to specimens properties bolt’s material. The tests mechanical and were material that bolt manufacture from it, a where failure occur inserted these program engineering (Ansys) calculate safety fatigue. results sho...

This paper presents the analysis, design, and preliminary testing of a prototype prosthetic foot for use in India. A concept consisting of a rigid structure with rotational joints at the ankle and metatarsal with rotational stiffnesses provided by springs is discussed. Because literature suggests that prosthetic feet that exhibit roll-over shapes similar to that of physiological feet allow more...

PURPOSE This study aimed to evaluate the effects of prosthetic foot types on the postural stability among transtibial amputees when standing on different support surfaces. MATERIALS AND METHODS The postural stability of 10 transtibial amputees wearing solid ankle cushion heel (SACH) foot, single-axis (SA) foot, and energy-saving and return (ESAR) foot was assessed. Results were compared with ...

Contrary to stance-phase dorsiflexion of conventional prosthetic feet, the microprocessor-controlled Proprio foot permits swing-phase dorsiflexion on stairs. The purpose of this study was to compare Symmetry in External Work (SEW) between a microprocessor-controlled foot and conventional prosthetic feet in two groups with unilateral transtibial amputation (Medicare Functional Classification Lev...

A review of prosthetic prescription practice reveals that in the United Kingdom about 85% of below and above-knee amputees are fitted with uniaxial feet, whereas in the United States about 80% are fitted with SACH feet. An evaluation method was developed to assess the performance of these two different types of feet. This included a subjective assessment procedure and a biomechanical evaluation...

The normal human running has been simulated by two-dimensional biped model with 7 segments. Series of normal running experiments were performed and data of ground reaction forces measured by force plate was analyzed and was fitted to some Fourier series. The model is capable to simulate running for different ages and weights at different running speeds. A proportional derivative control algorit...

To study and compare frontal plane kinetics and kinematics at knee joint during the gait cycle in persons with transtibial amputation using Patellar tendon bearing (PTB) suprapatellar (SP) cuff suspension and PTB supracondylar (SC) suspension, with SACH foot. Instrumented gait analysis was performed in 30 persons having unilateral transtibial amputation of traumatic origin using either PTB pros...

Recent advancement in prosthetic technology has led to the development of dynamic elastic response feet (DER), which are reported to store and release energy to facilitate gait. To date, there has been no objective evidence to suggest energy conservation while using these foot designs. The purpose of this study was to compare the energy expenditure of five commercially available prosthetic feet...

Zusammenfassung Im Beitrag werden Differenzkonstruktionen und praktische Ein‑/Ausschlussprozesse im formal inklusiven Grundschulsportunterricht untersucht. Auf Basis videographischer Daten wird in einer wissenssoziologischen, praxistheoretischen Perspektive an einem Fallbeispiel ein kollektiv-geteilter Orientierungsrahmen der Personifikation unterrichtlicher Handlungen aufgezeigt, dem drei Dime...

Die langfristige Sicherung der Wettbewerbsfähigkeit eines so breit aufgestellten Finanzdienstleisters wie der Allianz erfordert die Bereitstellung stabiler, performanter und funktionaler Anwendungssysteme. Die historisch begründeten dezentralen Strukturen im Versicherungswesen der Allianz mit den Stakeholdern der Bereiche Sach, Leben, Kranken und Vertrieb stellen die IT hier vor eine besondere ...
