OBJECTIVE Spasticity is a common complication with neurological diseases and CNS lesions. Instrumented systems to evaluate spasticity often cannot provide an immediate result, thus limiting their clinical usefulness. In this study we investigated the accuracy and reliability of the portable Neurokinetics RA1 Ridgidity Analyzer to measure stiffness of the ankle joint in 46 controls, 14 spinal co...

In this paper we present a solution of the adaptive control problem of the manipulator of robot Mitsubishi RV-1A at the end-effector motion on the optimal (in terms of a set of criteria) trajectories. For the trajectories planning a minimal torque changes criteria and a minimal discomfort criteria, founded with a biomechanical point of view was used. Control system that uses a linearized manipu...

SUMMARY Etching of sacrificial material is widely used in surface micromachining technology to form integrated micro mechanical structures. The process typically consists of three steps: the removal of sacrificial-layer material using liquid chemicals, rinsing, and removal of the rinse liquid (drying). The last step is known to cause surface sticking and drastic reduction of device yield. This ...

Muscular strength is generally measured using either of the following methods, one repetition maximum (1RM) of a weight-lifting exercise, a resisted maximal effort and portable or laboratory-based dynamometry. The 1RM method refers to measurements of maximum strength using a strength training device such as a barbell or stationary weight-lifting machine. Dynamometry can be divided into two sepa...
