The aim of this study was to correlate clinical and functional evaluations with kinematic variables of upper limp reach-to-grasp movement in patients with tetraplegia. Twenty chronic patients were selected to perform reach-to-grasp kinematic assessment using a target placed at a distance equal to the arm's length. Kinematic variables (hand peak velocity,(More)
A rehabilitation program toward restoring upper limb movements based on neuromuscular electrical stimulation (NMES) depends on closed-loop control performance, which has been limited by the development of sensors for practical daily use. This work proposes a system to obtain force feedback. The system is comprised of a Lycra commercial glove with force(More)
Medial opening-wedge has gained popularity in comparison to other techniques of high tibial osteotomy. This technique involves the creation of a gap in the tibia. Filling the gap with autologous iliac bone graft was recommended in the classic description, to prevent complications such as correction loss or delayed bone union. No previous reports have(More)
STUDY DESIGN This is cross-sectional study. OBJECTIVES The aim of this study is to investigate the cardiac structure and function of subjects with spinal cord injury (SCI) and the impact of metabolic, hemodynamic and inflammatory factors on these parameters. SETTING São Paulo, Brazil. METHODS Sixty-five nondiabetic, nonhypertensive, sedentary,(More)
A three-layer artificial neural network was used for adaptive control of gait swing generated by neuromuscular electrical stimulation (NMES) in a spinal cord injured subject. Network inputs consisted of knee and ankle goniometer signals for System 1, and knee and hip angular data for System 2. Controller output was proportional to changes in applied NMES(More)
The protection and management of protected areas must be adapted to the effects of climate change. An important question is if the law on protected areas is capable of dealing with the required changes. In general, both international nature conventions and European Union nature conservation law do not contain any specific provisions on climate change and(More)
The purpose of this study was to evaluate whether intraoperative nidus detection with a hand-held gamma probe was efficient enough for use as a routine procedure. Thirty-seven patients with osteoid-osteomas were submitted to surgical treatment. The first group consisted of 19 patients submitted to open nidus resection using a hand-held gamma probe as guide.(More)
The myoelectric signal can be used to control many rehabilitation systems, for instance, prostheses and artificial neuromuscular electrical stimulation toward restoring movement to spinal cord injured subjects. These mobile systems are usually used in different environments and thus are being exposed to different noise levels with characteristics not(More)
Quadriplegic subjects present extensive muscle mass paralysis which is responsible for the dramatic decrease in bone mass, increasing the risk of bone fractures. There has been much effort to find an efficient treatment to prevent or reverse this significant bone loss. We used 21 male subjects, mean age 31.95 +/- 8.01 years, with chronic quadriplegia,(More)
