Development and test results of a system for the recovery of the lower limbs

According to medical research,1 exertion of a certain level of loading to injured lower limbs is considered as important from the point of view of their recovery. Total unloading would decelerate coalescing of bones just like their permanent overloading. In order to avoid it, patients must be trained to walk with optimal load on lower limbs. A data logger with built-in load cell is designated both to sustain this process and to store data on load values exercised to limbs during recovery as well. The report below tells how this device was developed. DOI: 10.17489/biohun/2013/1/2

Is the Magyarmecske telluric conductivity anomaly a buried impact structure?

Abstract A more or less circular high-amplitude telluric conductivity anomaly is located at Magyarmecske, in southwestern Hungary. The authors collected and reinvestigated all available geophysical data previously measured in the area; based on this information it was concluded that the conductivity anomaly may well be explained as a buried impact crater. It is assumed that when the impact occurred, the target area was covered by a thick, coal-bearing Carboniferous sedimentary sequence. The projectile created a complex impact crater in these deposits, of a diameter of approximately 6–8 km. In the neighborhood of the crater the coal was modified by the impact's heat and pressure. Later the impact structure was partly eroded, partly deformed by younger tectonic movements, and covered by Neogene sediments of strongly variable thickness

Angel Heel rendszer: új mérési technika a részleges alsóvégtag-tehermentesítés tanításában és ellenőrzésében

In 2012 a three-round clinical trial started to test a new system developed by Metalelektro Méréstechnika Ltd. called Angel Heel by three different medical institutes. The tests of the system that was developed for controlling and training partial weight bearing based on acoustic feedback were performed with 150 people (in most cases after a hip or knee Total EndoProsthesis [TEP] surgery) in one year.The summarized results showed that the rate of patients’ lower limb overload decreased by 54% when the acoustic feedback of the system was activated. Also, the absolute amount of the overload was signifi cantly decreased (by 27%) related to the case when the acoustic feedback was deactivated. The clinical trial clearly proved the effi ciency of the Angel Heel system because it signifi - cantly decreased the amount and the rate of the injurious lower limb overloads during the rehabilitation.2012-ben indult az a három részből álló klinikai vizsgálatsorozat, amely során a DE OEC OrtopédiaiKlinika, a Kenézy Gyula Kórház és Rendelőintézet Rehabilitációs Osztálya és a DE OECOrvosi Rehabilitáció és Fizikális Medicina Tanszéke tesztelte a Metalelektro Méréstechnika Kft.által kifejlesztett Angel Heel nevezetű rendszert. A hangvisszajelzésen alapuló, az alsóvégtagrészleges tehermentesítésének kontrollálását és betanítását szolgáló rendszer tesztjei 150, főlegtérd- és csípőízületi total endoprosthesis (TEP) műtéten átesett résztvevő bevonásával, egy évalatt zajlottak le. Az összesített eredmények azt mutatták, hogy a rendszer hangvisszajelzésénekalkalmazásával az előre meghatározott maximális terhelést a betegek mintegy 54%-kal kisebbarányban lépik túl, valamint a túlterhelés mértéke is jelentősen, 27%-kal csökkent a hangjelzésalkalmazása nélküli esethez képest. A klinikai vizsgálatok egyértelműen bizonyították az AngelHeel rendszer hatékonyságát, hiszen lényegesen lecsökkenti a rehabilitáció során a káros következményekkeljáró alsóvégtag-túlterhelések arányát és mértékét is. DOI: 10.17489/biohun/2013/2/0
