The DIMETER system makes it easier for doctors and other health professionals to objectively evaluate the tremors exhibited in the hands and fingers of patients affected by some disorders that impair their motor skills, such as Parkinson, Amyotrophic lateral sclerosis, or Charcot-Marie-Tooth disease.
To make such measurements, DIMETER uses an electromechanical apparatus that is controlled by the hand or finger of the affected patient and registers the movement and the forces that are generated. Using this device and a computer monitor, doctors execute a series of virtual static and motion tests, such as trying to keep the hand at rest, or describing a set movement, like a straight line or a spiral. In any of these tests a weight can be added to the patient to evaluate the effect on the tremor while the system constantly monitors and records each movement.
The computer gathers the data and processes it to provide the doctor with the information needed for the patient’s evaluation in a numerical or graphical format to the level of detail required. This report is objective and precise and enables doctors to adjust their diagnosis of the condition and monitor the progression of the disease, or the effectiveness of the treatment.
Medical diagnosis tool
The new device, patented by the Universidad Politécnica de Madrid, has been co-developed by the researchers Antonio Barrientos and Roberto González from the Grupo de Investigación en Robótica y Cibernética of the UPM, with the colaboration of the Centro Estatal de Autonomía Personal y Ayudas Técnicas (CEAPAT) of the IMSERSO.
This tool, designed for medical consults, not only provides information of the type and degree of the tremor, but helps by offering a diagnostic. This way doctors have a corroboration of the diagnosis and treatment for the patient ensuring they are cared for effectively. Moreover, the system collates accurate data of each patient’s case, helping the investigation and improving the diagnoses and treatment of the diseases that present such symptoms.
The DIMETER system has already been used at the Ramón y Cajal hospital to undertake a study of the effect that the Deep Brain Stimulation technique has on the tremors. The use of this system has also helped the development of a new system called ACORTE that uses the processed data from the DIMETER to enable people suffering from tremors to use a conventional computer mouse.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
