The article describes an innovative mechatronic device for hand rehabilitation, which enables diagnostics, comprehensive exercises and reporting the rehabilitation results of individual fingers of people who have lost their full efficiency as a result of past illnesses (i.a. stroke) and orthopedic injuries. The basic purpose of the device is to provide controlled, active exercises of the individual fingers, to widen the range of their movements, and to increase their precision of movement. The developed mechatronic device works with original software for PCs containing a diagnostic module, reporting module and a set of virtual reality exercises using biofeedback. The device uses auditory and visual biofeedback, and electromyography (EMG).
Purpose: The aim of the study is to define the impact of exercise on a treadmill on static balance and stability of posture in a group of patients after cerebral stroke rehabilitated in a late period, with an application of a treadmill with the function of visual biofeedback. Methods: The examination was carried out in a group of 46 people in a late period after ischemic cerebral stroke. The patients examined were randomly put to a group with intervention (n = 23), in which a rehabilitation programme with an application of a treadmill with the visual feedback function was realized and to a control group (n = 23). They evaluated balance in standing on both feet by means of a force plate, symmetry of load of lower limbs and dynamic balance in Up & Go test. Results: A statistically significant change of stabilometric parameters was observed only in the area of postural sways of the centre of pressure (COP). A significant improvement of the symmetry of load of lower limbs in standing ( p = 0.0266) was diagnosed in the examined group after the end of the programme. After the end of the programme no significant difference between the group with intervention and the control group as for a change of balance of the examined patients was found. Conclusions: In the examined group in the chronic period after cs no significant improvement of stabilometrically evaluated balance was obtained, but improvement of the symmetry of load of lower limbs as well as improvement of dynamic balance were observed.
Cel. Celem pracy jest ocena wpływu rehabilitacji metodą PNF (Prorioceptive Neuromuscular Facilitation - torowanie nerwowo-mięśniowe) na poprawę równowagi pacjentów po udarze mózgu oraz ocena równowagi w zależności od wieku, strony niedowładu, okresu od wystąpienia udaru na podstawie badań posturograficznych. Materiał i metody. Badaniem objęto 32 pacjentów po udarze mózgu poddanych 12-tygodniowej rehabilitacji metodą PNF w Zakładzie Rehabilitacji Szpitala Uniwersyteckiego w Krakowie. Grupę badawczą stanowiło 8 kobiet i 24 mężczyzn w wieku od 25 do 73 lat. W celu oceny skuteczności terapii i jej wpływu na poprawę parametrów równowagi przeprowadzono dwukrotne badanie stabilności posturalnej na platformie posturograficznej: w pierwszym i ostatnim dniu terapii. Badanie wykonano przy oczach otwartych i zamkniętych oraz w warunkach sprzężenia zwrotnego. Zestaw badanych parametrów obejmował: średni promień wychyleń, pole powierzchni statokinezjogramu, długość drogi przebytej przez środek ciężkości oraz koordynację.Wyniki. Na podstawie przeprowadzonej analizy stwierdzono istotnie statystycznie zmiany wszystkich parametrów całej badanej grupy (poziom istotności p. 0,05). Porównując wyodrębnione grupy, można stwierdzić istotną statystycznie poprawę wybranych parametrów równowagi po terapii w grupie chorych do 59. roku życia, w grupie chorych do 12. miesiąca od udaru i w grupie z lewostronnym niedowładem. Wnioski. Fizjoterapia metodą PNF wpływa na poprawę równowagi w pozycji stojącej u pacjentów po udarze mózgu, co potwierdzają wyniki uzyskane w badaniu posturograficznym. Wydaje się, że posturografia pozwala na obiektywną ocenę postawy ciała pacjentów po udarze mózgu.

Aim. The aim of this study was to evaluate the influence of the PNF method (Proprioceptive Neuromuscular Facilitation) on a balance improvement in a group of patients after the stroke, as well as to evaluate the influence of age, side of paresis and time elapsed from a stroke on balance disorders in this group. Material and methods. The examination of 32 stroke patients, who participated in a 12-week rehabilitation session with the PNF method, was carried out at the Rehabilitation Unit of University Hospital in Krakow. The group consisted of 8 women and 24 men, in the age of 25 to 73. In order to assess the therapy effectiveness, posturography measurements were performed before and after therapy course. The posturographic test was performed with open and closed eyes and with the feedback conditions. The examined parameters were: average radius of deflection, area of the statokinesiogram surface, lengths of the distance covered by the gravity center, as well as parameters of coordination. Results. Statistically significant (p . 0,05) change was observed in all tested parameters measured before and after therapy in an entire group of patients. The statistically significant improvement was noticed after therapy in the group of stroke patients younger than 59 years old, in a group under 12 months after stroke and also in a group with left hemiparesis. Conclusions. Physiotherapy conducted by PNF method improves the body balance in case of patients subjected to cerebral strokes, what was confirmed by posturographic examinations. It seems that the posturography allows for the objective assessment of the posture stability in stroke patients.
