The design of these devices involves the human body as a support environment. Based on this premise, the development of wearable devices requires an improved understanding of the skin strain field of the body segment during human motion. This paper presents a new methodology to improve and optimize the design of wearable devices, specifically orthoses, based on the combination of biomechanical studies, computer aided design/computer aided engineering (CAD/CAE) tools and 3D printing technology.

A new exoskeleton for human gait motion assistance and rehabilitation is proposed, to investigate motion capabilities and feasibility. Human gait analysis on healthy and disabled subjects is performed to obtain references motion laws for normal gait. A dynamic simulation model of exoskeleton is achieved in ADAMS computational environment. The exoskeleton prototype motion laws, resulted from motion analysis based on ultra speed video cameras are compared with human subject motion laws.

In our study, our aim was biomechanically to investigate the effectiveness of Pertrochanteric Fixators (PTFs) applied with two different configurations of schanz screws inserted to the femoral head in ITFs.

In this study, the drilling process was performed with Kirschner wire (K-wire) for stabilization after reduction of Salter–Harris type-3 epiphyseal fractures of distal femur. The numerical analyses were performed with finite element method. An analytic model and software were developed to identify the temperature distributions occurring in the K-wire and sawbones material during drilling process. A good consistency was obtained between experimental results and finite element analysis results.
