Humanoid robots have been extensively studied in the last few years. The motivation for this study is that bipedal locomotion is superior to wheeled approaches on real terrain and situations where robots accompany or replace humans. Some examples are, on the development of human assisting device, such as prosthetics, orthotics, and devices for rehabilitation, rescue of wounded troops, maidens, ...

The construction of artificial muscles is one of the most challenging developments in today's biomedical science. The application of artificial muscles is focused both on the construction of orthotics and prosthetics for rehabilitation and prevention purposes and on building humanoid walking machines for robotics research. Research in biomechanics tries to explain the functioning and design of ...

BACKGROUND Energy expenditure and walking speed are generally recommended for use as measures of status and outcome for walking. The objective of this study was to measure the physiological cost index (PCI) and comfort walking speed (CWS) at three levels of lower limb amputation: transfemoral, transtibial and Syme level, and the relationship of these physiological variables to prosthetic ambula...

OBJECTIVE To assess prosthetic use by upper extremity amputees, and their difficulties with prostheses in activities of daily living and occupations. METHOD This study is based on a survey of 307 subjects, who were using prostheses manufactured in the Center of Prosthetics and Orthotics. The survey questionnaire included items about general demographic characteristics, side and level of amput...

Soft robotic systems generally require both soft actuators and soft sensors to perform complex functions. Separate actuators and sensors are often combined into one composite device when proprioception (self-sensing) is required. In this article, we introduce the concept of using a conductive liquid to perform both the sensing and actuation functions of a proprioceptive soft actuator. The worki...

This study made use of a controlled longitudinal design to assess the impact on pre-registration health and social care students of an interprofessional intervention on the attitudes to and perceptions of interprofessional ideals. Evaluation, over four years, of Nursing, Occupational Therapy, Podiatry, Prosthetics and Orthotics, Physiotherapy and Radiography students was performed using the ada...

OBJECTIVE To analyze the expenditure of the Ministry of Health with osteoporosis treatment in the Brazilian Public Health System (SUS) in 2008-2010 triennium and estimate the influence of demographic, regional and disease related variables on average expenditure per procedures performed. METHODS A cross-sectional, descriptive and analytical study based on secondary data from DATASUS related t...

BACKGROUND The interface pressure between the residual limb and prosthetic socket has a significant effect on an amputee's satisfaction and comfort. This paper presents the design and performance of a new prosthetic socket that uses an air splint system. METHODS The air splint prosthetic socket system was implemented by combining the air splint with a pressure sensor that the transhumeral use...

The purpose of this investigation was to develop a numerical method for fabricating prosthetic sockets for below-knee amputees. An optical/laser digitiser scans an amputee's stump and collects three dimensional numerical data describing the surface of the limb and describing specific modification site locations. The numerical data from the laser camera representing the stump and modification si...
