The aim of this article is to identify the benefits of multimedia education and its application in the process of motor learning and teaching. This descriptive study is based on the review of the literature and other authors’ research results. The use of multimedia tools in psychomotor education can facilitate the visualisation of motor activities and the creation of a motor program. The use of multimedia education in the teaching of downhill skiing can help students achieve good results.

The study examines whether clinical and objective improvement can be achieved in patients with LBP (low back pain) with radicular symptoms using a 6-week exercise program based on press up exercises created from ADL (activities of daily living) movement patterns. This original study involved 10 men with acute L5 / S1 disc hernia. Before starting the exercise program, patients determined the intensity of pain VAS (Visual Analogue Scale), the intensity of paraesthesias (NSIP: numerical scale of paraesthesia intensity) and the location of paraesthesias. Magnetic resonance imaging (MRI) was used to objectify the extent of the disc hernia, spinal cord compression, and pressure acting on the dural sac. Patients completed -week exercise program consisting only of press up ADL movement patterns in a closed kinematic chain. At the end of the exercise program, patients determined the outcome values of clinical symptoms and underwent control MRI within 2 weeks at the latest. At the end of the study all patients showed a statistically significant reduction in pain intensity (p = 0.005), paraesthesia (p = 0.006). The pressure on the dural sac was reduced in all patients. One of the patients had a partial reduction of intervertebral disc hernia by 35.7 %. None of the patients had a change in spinal root compression. Conventional therapy should focus on influencing clinical symptoms that appear to correlate with dural sac compression. We dare to argue that reduction of hernia disc is not a sign of primary recovery in LBP patients with acute phase radicular symptoms.

Purpose. In this study, we investigated the effects of the distribution of practice (distributed vs. massed) on the learning of a coincident timing task by young and older adults. Methods. Sixteen young adults and sixteen older adults were subdivided into distributed and massed practice groups. The participants completed a coincident timing task that consisted in touching five sensors in sequence under a time constraint in two learning phases: acquisition and transfer. Results. There were no performance differences between the groups in the acquisition phase. However, older adults in the massed practice group featured the poorest performance in the transfer test. No differences were found among the other groups. Conclusions. Older adults are more receptive to distribution practice as massed practice was found to lead to poorer learning. Comparisons of learning effectiveness between young and older adults are dependent on the adopted intra-session intervals. In addition, the conflicting results on distribution of practice may be related to subject-task interactions.

The aim of this study was to investigate whether a single bout of core stability exercises improves body balance immediately after the bout of exercise and during a retention test. Methods: The study involved 16 women (age 22–25 years, body weight 60.5 ± 5.2 kg, height 166 ± 5.4 cm). Postural stability was assessed in the mediolateral (ML) and anteroposterior (AP) planes separately on a force plate (Kistler 9286 AA) during quiet standing on a soft support surface with the eyes closed. Subjects were measured 4 times: just before (T0), 1 minutes after (T1 m), 30 minutes after (T30 m), and 24 hours after the workout (T24 h). Postural balance was evaluated by five parameters based on the center of pressure (COP) signal: variability (VAR), mean velocity (VEL), sample entropy (ENT), frequency (FRE), and fractal dimension (FRA). Results: We observed a decrease in VAR and VEL in the ML plane at T30 m and T24 h, compared to T0. The COP entropy significantly increased in the ML plane at T24 h, compared to T0. Conclusions: A single bout of core stability exercises improved the control of the mediolateral body balance. This effect was evident within 30 minutes after exercise, and remained for at least 24 hours. In addition, 24 hours after exercise we observed an increased automaticity in the strategy to maintain a stable upright stance.

Background. Cerebral palsy (CP) is associated with non–progressive damage to the upper motor neuron, which manifests itself in a variety of symptoms, in particular motor and functional deficits. In the development of a child, especially with CP, attention should be paid to regulation disorders of sensory processing (RDSP). They result from incorrect processing of information by the nervous system and, therefore, may affect cognitive processes, the ability to move and the process of motor learning. The aim of the study was to analyze the relationship between disturbances in the regulation of sensory processes and the development of gait function and motor learning in a group of children and adolescents with MPD. Material and methods. The study involved 50 patients with CP, whose functional and kinematic parameters of locomotion were measured and whose sensory profile was defined on the basis of a standardized questionnaire of sensorimotor disorders completed by their parents or legal guardians. Then, a test of correlation between individual variables was performed. Results. Disturbances in sensory integration processes were shown to be associated with less favorable functional and kinematic values and with lower efficiency of motor learning. This was especially true of proprioception and balance as well as coordination, which depends on cooperation between the sensory organs. Conclusions. 1. These results correlate with the outcomes of other studies on the relationship between sensory impairment and motor skills. 2. The study may contribute to the identification of more predictors of the effectiveness of rehabilitation of patients with CP, which can be used in the longer term to forecast the effects of therapy and the development of personalized medicine, as manifested in comprehensive therapeutic approaches (e.g. supplemented with sensory integration therapy).

Wstęp. Mózgowe porażenie dziecięce (MPD) wiąże się z niepostępującym uszkodzeniem górnego neuronu ruchowego, co przejawia się różnorodnymi objawami, w szczególności deficytami motorycznymi i funkcjonalnymi. W rozwoju dziecka, szczególnie z MPD, należy zwracać uwagę na zaburzenia regulacji procesów sensorycznych (RDSP). Wynikają one z nieprawidłowości w przetwarzaniu informacji przez układ nerwowy, dlatego też mogą mieć wpływ na procesy poznawcze, zdolność poruszania się, czy proces motorycznego uczenia się. Celem pracy była analiza związku zaburzeń regulacji procesów sensorycznych z rozwojem funkcji chodu oraz motorycznym uczeniem się w grupie dzieci i młodzieży z MPD. Materiał i metody. W prezentowanym badaniu wzięło udział 50 chorych z MPD, u których dokonano pomiaru parametrów funkcjonalnych i kinematycznych lokomocji, a także u których zdefiniowano profil sensoryczny na podstawie standaryzowanego kwestionariusza zaburzeń sensomotorycznych wypełnianego przez rodziców lub prawnych opiekunów. Następnie dokonano testu korelacji pomiędzy poszczególnymi zmiennymi. Wyniki. Wykazano, że zaburzenia procesów integracji sensorycznej wiążą się z mniej korzystnymi wartościami funkcjonalnymi i kinematycznymi oraz z mniejszą efektywnością motorycznego uczenia się. Dotyczy to szczególnie propriocepcji i równowagi oraz koordynacji – zdolności budowanej na współpracy narządów sensorycznych. Wnioski. 1. Wyniki korelują z innymi badaniami dotyczącymi związku zaburzeń sensorycznych ze zdolnościami motorycznymi. 2. Badanie może posłużyć jako element identyfikacji kolejnych predyktorów efektywności rehabilitacji chorych z MPD, co w dalszej perspektywie może posłużyć do prognozowania efektów terapii oraz rozwoju medycyny spersonalizowanej przejawiającej się m.in. w kompleksowej terapii (np. uzupełnionej o terapię integracji sensorycznej).
