Abstract		Repeatability is an indispensable characteristic needed in systems for gait re-education in incomplete spinal cord injury and hemiparetic patients. In contemporary rehabilitation, where the treadmill and the physiotherapists' assistance play a main role, it is not possible to ensure sufficient degree of repeatability. We have developed a gait re-education system that uses a multisensor device for swing phase estimation to ensure the reliable and repeatable evaluation. In incomplete spinal cord injured persons some of the motive complexes have been affected and to restore the movement a functional electrical stimulation could be an assistive approach. Combining the stimulated and voluntary sensory gait reeducation supported exercise, a promising outcome of the rehabilitation can be expected. The developed re-education system was tested in an incomplete spinal cord injured patient with C4-5 lesion during . treadmill walking. The patients' task was to focus on cognitive feedback, providing the information of the swing phase guality, and perform a swing. The computer controlled electrical stimulation and provided the level of assistance needed on the basis of the information on a given number of consecutively performed swings. The approach resulted in signifzcant gait improvement, since the stimulation assistance was significantly decreased comparing to the intensity level at the beginning of the session.
Summary		Sisteme za ponovno učenje hoje po poškodbi hrbtenjače in hemiparezi združuje ponovljivost, lastnost, brez katere si učenja ni moč predstavljati. Pri sodobni rehabilitaciji, kjer imata glavno vlogo tekoči trak in pomoč fizioterapevtov, tega ni moč zagotoviti. Razvili smo sistem za ponovno učenje hoje, ki vsebuje večsenzorni sistem za ocenjevanje kvalitete zamaha, s katerim zagotovimo zanesljivo in ponovljivo oceno. Pri osebah z nepopolno poškodbo hrbtenjače, kjer so prizadeti nekateri gibalni sklopi, nam je v veliko pomoč pri restavraciji hoje funkcionalna električna stimulacija. S kombinacijo stimulirane in hotene hoje lahko ob podpori senzornega sistema dosežemo vzpodbudne rezultate pri rehabilitaciji hoje. Izdelan sistem za re-edukacijo je bil preskušen na pacientu z nepopolno poškodbo C4-5 pri hoji na tekočem traku. Pacientova naloga je bila, osredotočiti se na kognitivno informacijo o kvaliteti izvedenega zamaha in hoteno izvesti korak. Pri tem mu je bila v pomoč stimulacija, v kolikor je bilo to potrebno, kar je nadzoroval računalnik glede na kvaliteto zaporedno izvedenih zamahov. Izkazalo se je, da se je kvaliteta pacientovih zamahov izboljšala na višjo raven, tako da je bila podpora električne stimulacije veliko nižja, kakor v začetku.
