W ramach pracy przeprowadzone zostały badania wspomagające proces przygotowania i doboru zindywidualizowanych ortez kończyny dolnej. Badania obejmowały analizę chodu pacjentów z mózgowym porażeniem dziecięcym MPD o różnej postaci i stopniu upośledzenia ruchowego. W przypadku wszystkich przebadanych dzieci wyniki badań chodu wykorzystano do przygotowania zaopatrzenia ortopedycznego w postaci ortez stopy i stawu skokowego AFO lub dynamicznej ortezy stopy i stawu skokowego DAFO. W artykule przedstawiono również metodykę analizy wytrzymałościowej ortez z wykorzystaniem metody elementów skończonych (MES). W procesie przygotowania indywidualnych ortez do rehabilitacji wykorzystano ręczny skaner 3D. Na podstawie rezultatów skanowania opracowano model geometryczny 3D spersonalizowanej ortezy stawu skokowego, a następnie model dyskretny 3D. Obliczenia wytrzymałościowe modelu MES ortezy pozwoliły dobrać optymalną grubość ortezy.

The research is concerned with support of the process of preparation and selection of lower limb individual orthosis. The paper presents the analysis of gait in patients with cerebral palsy CP in varying forms and degrees of motor impairment. The results obtained from laboratory tests of children’s gait were used for the preparation of orthopedic orthosis in the form of AFO (ankle foot orthosis) type or DAFO (dynamic ankle foot orthosis) type. The article also describes the methodology of strength analysis of orthosis with the use of the Finite Element Method (FEM). A manual 3D scanner was applied in the process of the preparation of individual orthosis. A 3D geometrical model was developed for individual ankle orthosis based on the results of the scan. Further a devised 3D discretized model FEM allowed to carry out of strength analysis and choose the optimum orthosis thickness.

Purpose: of this paper is to presents a method of interactive rehabilitation based on a mechatronic system supporting psychomotor rehabilitation of children with lower limbs dysfunction. Design/methodology/approach: The method is grounded on stimulation of senses through image and sound. To achieve this purpose one used modern multimedia solutions in conjunction with an intelligent controlling system. The system controls the degree of the set rehabilitation load as well as measures the child’s concentration. Findings: The proposed method is a kind of contemporary physiotherapy which combines traditional cyclotherapy and stimulation of the child’s intellectual development by means of Glenn Doman’s improvement method or with the use of music therapy depending on the degree of the child’s intellectual development. Therapeutic activities undertaken with the use of the developed equipment may in the case of paresis or paralysis restore the action of the muscles by improving their elasticity or increasing their ability to react to stimulation of the nervous system. Research limitations/implications: The combination of movement therapy with psychological stimulation enables the children to use their abilities more efficiently and speeds up the rehabilitation process. Practical implications: The application of the equipment in question increases efficiency of the therapists’ and parents’ actions, being at the same time a vital element supporting the laborious and painstaking process of rehabilitation of little patients. Originality/value: The method consists in movement therapy combined with simultaneous psychological stimulation of the child.

Rehabilitation will take place in the form of a play with the use of specially designed equipment. Design/methodology/approach: This work reviews selected methods of improving the children’s condition, which methods may be applied in interactive rehabilitation. Findings: The combination of movement-based therapy with mental stimulation will make it possible to use the child’s potential in a more effective way and quicken the process of rehabilitation. Research limitations/implications: In further stages of works it is expected to make a prototype device that can be transferred to a public benefit organization or an organization of a similar nature in order to conduct researches within their own works. Practical implications: The combination of movement therapy with psychological stimulation will exploit, to the maximum extent, natural abilities of brain development in small children. This is enormously important as it is often a factor that conditions the length and, first of all, the quality of life of the patients. Originality/value: The device being developed will include all the most important factors that may affect the physical structure of children and their psyche, which can directly affect the improvement of their health.

Purpose: This article presents the concept of an interactive rehabilitation equipment designed for children under 3 years of age with dysfunction of the lower limbs. Through the use of interactive play-boards and games not only will the children learn faster, but the whole process of rehabilitation will be really fun. Furthermore, the device can be connected to a computer or a special synoptic screen mounted on a special rack. Thanks to an interactive combination of the function of movement rehabilitation with mental stimulation of a child it will be possible to support the development of cognitive functions, cause-effect thinking, stimulation of the senses and to improve coordination and spatial orientation of the young patient. Design/methodology/approach: The novelty of the station is combination of the traditional cycle-therapy with the Glenn Doman improvement method, or with music therapy, depending on the degree of disability of a child. Findings: Combination of the traditional cycle-therapy with music therapy or Glenn Doman’s method in rehabilitation of small patients will help to maximize the children’s activity and their involvement, which at this stage of development is possible only by giving rehabilitation exercises an attractive form of plays and games. Research limitations/implications: FMEA is a very important method which should be employed in companies fPractical implications: The researches from the broadly understood biomechanics that are carried out shall lead to a construction of a rehabilitation device designed for children under the age of three. The proposed device should be very effective in the rehabilitation process, even for the youngest children, and due to its relatively simple modular construction and the possibility of cooperation with many plays and games, it should also be a market success by contributing to the effective rehabilitation of the considerable population of children who require such rehabilitation. Originality/value: The device being developed will include all the most important factors that may affect the physical structure of children and their psyche, which can directly affect the improvement of their health.

W pracy przedstawiono koncepcję stacjonarnego, interaktywnego rowerka rehabilitacyjnego dla dzieci poniżej trzeciego roku życia. Rehabilitacja małych dzieci musi być dostosowana do ich potrzeb oraz możliwości, a także powinna w sposób wszechstronny uwzględniać ich odrębność strukturalną i czynnościową wynikającą z wieku. Leczenie dysfunkcji kończyn dolnych przy minimalnej świadomości dziecka podczas zabawy podnosi atrakcyjność rehabilitacji, zwiększając zainteresowanie małego pacjenta oraz umożliwia dłuższe wykonywanie różnych czynności nie powodując znudzenia. Koncepcję rowerku wykonano w programie Autodesk Inventor.

This paper presents the concept of a stationary, interactive rehabilitation bicycle for children below the age of three. The rehabilitation of small children has to be adjusted to their needs and possibilities and it should comprehensively take into account children’s structural and functional diversity related to their age. The treatment of dysfunction of lower limbs while the child is barely aware of it during play, increases the attractiveness of rehabilitation and thus child’s engagement and allows for longer exercises that do not cause boredom. The concept of the bicycle has been prepared with the use of Inventor software.
