“…The affected areas of the brain belong to the cortex. In this case, some works consider that the frequency range of this tremor is between 4.5 and 8 Hz [8], while other authors establish it between 4 and 8 Hz [7]. The frequency and amplitude increase with age.…”

“…If patients make a voluntary movement, then the tremor stops for a moment, but when the movement ends, the tremor continues with a slight to moderate intensity. Some previous works have estimated that the frequency of this tremor is in the range from 3.5 to 6 Hz [8], while others consider it to be between 4 and 6 Hz [7].…”

ABSTRACT:Human tremor can be defined as a somewhat rhythmic and quick movement of one or more body parts. In some people, it is a symptom of a neurological disorder. From the mathematical point of view, human tremor can be defined as a weighted contribution of different sinusoidal signals which causes oscillations of some parts of the body. This sinusoidal is repeated over time, but its amplitude and frequency change slowly. This is why amplitude and frequency are considered important factors in the tremor characterization, and thus for its diagnosis. In this paper, a tool for the prediagnosis of the human tremor is presented. This tool uses a low cost device (<$40) and allows to compute the main factors of the human tremor accurately. Real cases have been tested using the algorithms developed in this investigation. The patients suffered from different tremor severities, and the components of amplitude and frequency were computed using a series of tests. These additional measures will help the experts to make better diagnoses allowing them to focus on specific stages of the test or get an overview of these tests. From the experimental, we stated that not all tests are valid for every patient to give a diagnosis. Guided by years of experience, the expert will decide which test or set of tests are the most appropriate for a patient.Keywords: human tremor, Wiimote® device, filtering techniques, prediagnosis tool. RESUMEN:El temblor humano puede definirse como un movimiento rápido y, en cierta manera, rítmico de una o más partes del cuerpo. En algunas personas, este movimiento puede ser un síntoma de alguna alteración a nivel neurológico. Desde el punto de vista matemático, el temblor humano puede ser definido como una suma ponderada de diferentes señales sinusoidales que causan oscilaciones de algunas partes del cuerpo. Esta sinusoide se repite en el tiempo pero su amplitud y frecuencia cambian lentamente. Por esta razón, la amplitud y la frecuencia son consideradas factores importantes en la clasificación del temblor y por tanto útiles en su diagnóstico. En este artículo, se presenta una herramienta de ayuda al diagnóstico del temblor humano. Esta herramienta usa un dispositivo hardware de bajo coste (<$40) y permite calcular las principales componentes de esta sinusoide asociada al temblor de una manera precisa. Como casos de estudio se presentan su aplicación a dos casos reales para probar la bondad de los algoritmos desarrollados. Los casos muestran pacientes que sufrían temblores con distinta severidad y que han realizado una serie de tests con el dispositivo para que el sistema calculara las principales componentes del temblor. Estas medidas aportadas por el sistema ayudarían en un futuro a los expertos a tomar decisiones más precisas permitiéndoles centrarse en determinadas fases del test o la realización de tests más específicos para evaluar mejor las características propias del temblor del paciente. De la experimentación realizada podemos afirmar que no todos los tests son válidos para el diagnóstico para ...

“…Strokes are the third most common cause of death worldwide after heart disease and cancer (The Stroke Association, UK, 2008), and the most common cause of acquired physical disability. Tremor on the other hand, is one of the major causes of functional disability and the most common disorder in neurological practice, affecting mostly the elderly population [19][20][21]. Chronic neurological pain can worsen due to anxiety/stress and other factors.…”

Although technology and computation power have become more and more present in our daily lives, we have yet to see the same tendency in robotics applied to health care. In this work we focused on the study of four distinct applications of robotic technology to health care, named Robotic Assisted Surgery, Robotics in Rehabilitation, Prosthetics and Companion Robotic Systems. We identified the main roadblocks that are limiting the progress of such applications by an extensive examination of recent reports. Based on the limitations of the practical use of current robotic technology for health care we proposed a general modularization approach for the conception and implementation of specific robotic devices. The main conclusions of this review are: (i) There is a clear need of the adaptation of robotic technology (closed loop) to the user, so that robotics can be widely accepted and used in the context of heath care; (ii) For all studied robotic technologies cost is still prohibitive and limits their wide use. The reduction of costs influences technology acceptability, thus innovation by using cheaper computer systems and sensors are relevant and should be taken into account in the implementation of robotic systems.

Decision support: It refers to custom-developed algorithms combining and analyzing medical data to provide decision support. These are usually based on fuzzy logic or neural network models. * Feedback: Deals with decisions involving the nature, frequency, and quality of the feedback provided to the patients. * Risk analysis: It deals with security problems for each specific application and helps in determining contingency plans to ensure a level of security corresponding to the level of risks. * Telemedicine Service: It deals with data compatibility issues with the central patient medical record, the ability to use this information for research purposes, data transfer security, and the health service intervention time in emergency situations.
