The objective of this work is to study and design a portable non invasive prototype which allows us to supervise the mastication frequency and pressure for specific meals, performing an analysis of sounds and pressures generated by facial muscles when they are chewing. These variables have a direct influence on people nutritious and dietary habits; also, a quickly eating makes people ingest a lot...
Distribution of Foot Pressure reflects the deformations of body biomechanical design. They are caused by different reasons: degenerative, by trauma, etc., being flat foots a common pathology in Peru with high incidence. However there isn't the properly technology to detect properly this disease because is detected by a non-reliable visual way using pedoscopes. Flat foot is the degree of internal plantar...
The purpose of this study is to develop a new ultrasound diagnostic system for non-invasive and quantitative assessment of mechanical properties of the bone or bone healing. In the previous papers, we reported that we had developed a new ultrasound system to measure a minute bone deformation using a multi-point echo-tracking (ET) and that it had a great potential for non-invasive and quantitative...
For femoral fracture reduction, we have developed a surgical robotic system. Indirect traction is employed in our system. Indirect traction in fracture reduction is a generally used surgical method for preventing complications such as bone splits caused by high stress on bones. For traction, a patientpsilas foot is gripped by a jig and pulled to the distal side. Indirect traction has the advantage...
In the previous paper, we reported that an ultrasound system using multi-point echo-tracking (ET) could have a great potential for non-invasive and quantitative diagnosis of bone healing. In this study, the results of a clinical evaluation of the previous method were reviewed and we further improved the ET system to obtain the higher accuracy. The objective of this study was to develop a new ultrasound...
To evaluate bone strength, it is significant to measure the degree of deformation or strain of bone under a certain load. However no method has been available to non-invasively measure bone deformation. To obtain bone mechanical properties such as elasticity, viscoelasticity and plasticity, we need to externally apply a load to a bone and to accurately measure the small displacement of a specific...
