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...
Background It is usually challenging to achieve surfaces that are highly adhesive, yet can be detached easily. Geckos’ foot hairs, however, can be easily detached from a surface even though they adhere to it strongly enough to hold the animal’s body against gravity. Inspired by Nature, a combination of strong adhesion and easy detachment in adhesion system can be achieved and the possibility of...
Musculoskeletal conditions of the foot and ankle are an important public health challenge due to their increasing incidence combined with their substantial negative impact on patients' quality of life. Non-pharmacological treatments serve as the first line of treatment and are frequently used for patients with musculoskeletal conditions of the foot and ankle. This review provides a summary of t...
BACKGROUND Quantifying detailed 3-dimensional (3D) kinematics of the foot in contact with the ground during locomotion is crucial for understanding the biomechanical functions of the complex musculoskeletal structure of the foot. Biplanar X-ray fluoroscopic systems and model-based registration techniques have recently been employed to capture and visualise 3D foot bone movements in vivo, but su...
asymmetric polyethersulfone (pes) microfiltration flat sheet membranes were composed by the phase inversion method (pim) and were used as supports. composite membranes were fabricated by coating silicone rubber as selective layer. effect of different concentrations of pes and pdms and different solvent such as nmp, dmf and dms effects as pes solvents and support thickness and different coagulat...
A model for head, tentacle, and foot formation in Hydra is proposed. The model shows that systems which suggest a positional information scheme may be realized by a set of hierarchically coupled pattern forming systems: a structure generates the precondition for a second structure but excludes this structure locally. In this way, a well-regulated neighborhood of structures is enforced. Accordin...
Objective: The aim of this study was to evaluate the effect of unstable shoes on the sole of the shoes pressure of walking in healthy male students with different geometric shapes. Today, various shoes have been developed to reduce the effects of injury parameters and improve performance parameters for walking. Methods: 20 of the healthy male lambs were selected 178.96 ± 3.92 cm, 27 ± 3 years...
