The motor system involves coupling a Slide-skate mechanism to a planetary system consisting of two gears; joined together by two rotation pairs that ensure the successful operation of the couple ensemble. The planetary system was constructed in its simplest technological variant: based on a diameter of the gear pair to obtain a small step (200mm) to facilitate the process of gait retraining in patients with limited locomotion induced by neurological diseases and/or stroke. The coupling allows the regulation of the gait step without changing the gear pairs. The slide performs a similar work of radio-variable crank. The motor system was designed to ensure the continuous regulation of the step within the range of 200 to 450 mm while retrains normal gait without change gear pairs or altering the duration percentage of the two main phases of the human gait cycle.","PeriodicalId":151015,"journal":{"name":"2013 Pan American Health Care Exchanges (PAHCE)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130521195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Steady images or real-time video can be projected on the helmet together with a selected visual impairment.

We develop a preliminary computational model of excitable single neurons that simulates the voltage-gated currents as well as the pH and Ca2+ sensitive K+ currents. This work yield valuable insights into the neuronal properties that determine chemosensitive gain and support the hypothesis that braking pathways may play a more significant role in setting single cell responses to CO2/H+ in central chemosensitive neurons. These results are thus likely to delineate the investigation about new therapeutic targets for drugs aimed at altering central chemosensitive gain for the treatment of major disorders.","PeriodicalId":151015,"journal":{"name":"2013 Pan American Health Care Exchanges (PAHCE)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127577246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
