W ramach pracy przeprowadzono badania zdolności utrzymywania równowagi dzieci z mózgowym porażeniem dziecięcym. Pomiary przeprowadzone na platformie stabilograficznej ZEBRIS FDM-S objęły grupę 16 dzieci. Główne parametry, które zostały wzięte pod uwagę to długość ścieżki oraz pole elipsypodparcia. Analizę wyników przeprowadzono uwzględniając podział grupy badanych na dzieci z diparezą oraz hemiparezą. Uzyskane wyniki porównano z rezultatami badań innych autorów.

This essay focuses on the ability to maintain a balance by children with cerebral palsy. Test group included 16 children (5 with diparesis and 11 with hemiparesis). Measurements were carried out on the Zebris FDM-S stabilographic platform. The main parameters that were taken into consideration were the length of the track and the support ellipse area. Final analysis contains the results of children division into two groups – with diperesis and hemiparesis. Results were compared with research carried out by the other authors.

U pacjentów z niedowładem połowiczym występuje znacznie zaburzony wzorzec chodu. Przeprowadzono analizę rozkładu sił i symetrii ciała przy zastosowaniu standardowego zaopatrzenia ortopedycznego podczas reedukacji chodu u pacjentów z hemiplegią. Artykuł ma na celu zwrócenie uwagi na potrzebę bardzo ostrożnego doboru zaopatrzenia ortopedycznego dla pacjentów z niedowładem połowiczym oraz przedstawia alternatywne metody postępowania.

The study was based on many experiments of gait characteristics analysis, finally on observations of 117 patients suffering from motor disturbances. Among them were 42 cases with hemiparetic syndrome, mostly after cerebral stroke, 52 cases affected by acute sciatic neuralgia and 23 patients with recognition of Parkinson - disease symptoms. The control group was 16 healthy adults selected from medical staff - examined by pedobarographic equipment - PSW [4]. Based on these observations several classification proposals have been introduced. The majority of works concern gait disturbances investigations for three remarkable neurological diseases. They provide us with new diagnostic techniques based on some gait measures implementation.

The aim of this study was to estimate the strength of spastic muscles using Biodex System 3 within a group of patients with hemiparesis in after-stroke population. Measurements of the moments of force in elbow flexors and extensors of both spastic and non-spastic limbs were conducted under isostatic conditions. We analysed the values obtained for both limbs in order to determine the spasticity level on an Ashworth scale (0–4). The subjects were 10 patients with hemiparesis and varying spasticity selected from an after-stroke population. The analysis showed that spastic muscles activated less force than non-spastic muscles of the same patient. Furthermore, in a spastic limb, higher values of force were noted in the flexors than in the extensors of the elbow. In a non-spastic limb, the values of force were higher in the extensors of the elbow joint than in flexors. It is worth adding that the dynamics of force exposure, defined by a gradient of force, was much lower in spastic muscles than in non-spastic ones. Objective estimation of muscle force can be done by measuring the moments of force in particular groups of muscles upon the isokinetic contraction appearing. The repeatability of measurements may enable the kind of kinesitherapy to be determined as well as the assessment of the effectiveness of exercises in regard to force increase and dynamics of spastic muscles.

Udary mózgu, będące dramatycznym powikłaniem chorób układu naczyniowego, stanowią duży problem zdrowotny we współczesnym społeczeństwie, prowadząc do niepełnosprawności, otępienia i depresji, a często też do śmierci. Trudności w chodzeniu stwierdza się u 70% osób przeżywających udar, natomiast u 30% utrzymuje się ciężkie upośledzenie ruchowe, wymagające stałej opieki. Dlatego istotnym zagadnieniem jest problem przywrócenia lokomocji lub jej usprawnienia. Celem pracy była jakościowa i ilościowa ocena chodu osób po udarze mózgu z niedowładem połowiczym prawo- i lewostronnym. U 25 osób (17 osób z niedowładem połowiczym prawostronnym, 8 osób z niedowładem połowiczym lewostronnym) przeprowadzono ocenę funkcjonalną niedowładnej kończyny dolnej, ocenę chodu (wydolność chodu, sprawność chodu) oraz dystans chodu. Analizowano zależność pomiędzy stanem neurologicznym a lokomocją. Wykazano istotną statystycznie zależność między badanymi cechami. Wyniki przeprowadzonych badań wskazują na potrzebę wykonywania neurologicznej i funkcjonalnej oceny chorych po udarze oraz monitorowania postępowania usprawniającego. Brak poprawy może być wskazaniem do dokonania zmian w programie rehabilitacyjnym, szczególnie w pierwszych miesiącach po udarze. Wyniki postępowania fizjoterapeutycznego zależą w dużej mierze od wyboru właściwej strategii leczenia.

Apoplectic stroke is a dramatic complication of the cardiovascular system's diseases and it has become one of the most distressing health problems of contemporary societies. Often it results in handicap, postapoplectic dementia, depression and high death rate. Around 70% of survivors have difficulties in walking, while the remaining 30% suffer from acute motor impairment and require constant medical attention. Therefore, restoration or, at least, improvement of locomotion is the main goal of rehabilitation of the cerebral hemorrhage survivors. Studies on gait pathologies provide valuable clues for planning physiotherapy that would minimize or eliminate the given dysfunction. The aim of this study was qualitative and quantitative evaluation of gait in cerebral hemorrhage survivors with the right- or the left-sided hemiparesis. 25 patients (17 with the right-sided and 8 with the left-sided hemiparesis) were subjected to functional evaluation of the paretic lower limb, gait evaluation (gait efficiency and gait ability) and walking distance assessment. Correlation between the neurological and locomotor status of the patients was evaluated. The analysis showed a statistically signify- cant correlation between the examined traits. It also indicates a necessity for performing neurological and functional evaluation of patients after stroke and monitoring of the rehabilitation progress. Lack of improvement may indicate that the rehabilitation scheme needs to be altered, especially in the first months after the stroke. The final effect of rehabilitation depends, to a large extent, on the choice of appropriate physiotherapeutic strategy.

Present medicine uses computers in various applications, especially in a field of a diseases level classification and diagnosis. In many cases an automatic conclusion making units are the main goal of the computer systems usage. The software units are developed for the diseases classification or for monitoring of the disease medical treatment. An example application was described in this paper. It concerns a gait abnormalities level analysis that is described by a data records gathered by insoles of Parotec System for Windows (PSW) [17,18]. The PSW software package is used for visualisation of the gait characteristic static and dynamic characteristic features. In the authors' works many additional data components were distinguished. The field of the applications is located within the neurological gait characteristics also the source applications concern orthopaedics [16,18]. Careful analysis of the data provided the developers with new areas the PSW applications [4,11,13]. For conclusion making units the artificial networks theory was implemented [2,4,11,13]. For more effective training of the neural networks specific characteristic measures were introduced [4,5]. They allow controlling the training process more precisely, avoiding mistakes in current records classification.

To the control group 16 healthy adults was selected from our medical staff. All subjects were examined using pedobarographic equipment - Parotec System for Windows (PSW) [1]. Based on these observations several pattern solutions have been introduced. They concern gait disturbances in three distinguished neurological diseases. These findings extracted a new data from the PSW records and options and new diagnostic techniques based on the gait characteristics observation.

This study was based on 27 patients' motor gait disturbances analysis using their pedobarographic records, affected by neurological diseases - hemiparesis or sciatic neuralgia. The evidence comparison concerns the data records collected before and after the rehabilitation processes. The essential conclusions explain a walk characteristics analysis explaining the neurological status of the patient and how to implement the PSW [2, 3] options in clinical practice. This approach can also be used for medical jurisdiction processes as a unique tool for the disease evidence making.
