“…Similar results were obtained by Thomson et al from Montreal [8]. The research of Karnat and Schndler revealed that vibratory massage of muscles of the back of the neck results in an improvement of spatial orientation [9,10]. On the basis of an experiment carried out in a group of 120 volunteers Newman and Lederman from London stated that vibratory massage of the quadriceps muscle of thigh does not improve excitability of motoneurons [11].…”

WprowadzenieMasaż wibracyjny wywiera wpływ na rodzaj czucia głębo-kiego, zwany propriocepcją. Propriocepcję defi niuje się jako wyspecjalizowaną funkcję czuciową obejmującą zmysł orientacji ułożenia części własnego ciała, ich ruchu (kinestezja) i czucie wibracji. Receptory zapewniające propriocepcję -mechanoreceptory -ulokowane są w mięśniach i ścięg-nach. Dostarczają one także mózgowi informacji o tonusie mięśniowym. Za czucie wibracji odpowiadają duże, kuliste ciałka Vatera-Paciniego, obecne głównie w głębokich warstwach skóry, w ścięgnach, torebkach stawowych i okostnej. Włókno nerwowe otoczone jest wielowarstwowym, koncentrycznym układem spłaszczonych komórek Schwanna, pomiędzy którymi znajduje się płyn tkankowy [1,2]. Masaż wibracyjny ręcznyMasaż ręczny znany jest od tysięcy lat. Jednym z istotnych elementów masażu klasycznego jest technika wibracyjna [3]. Masażysta wykonuje ruchy "trzęsące" ręką powodując wibrację tkanki podskórnej. Najczęściej celem tego typu masażu jest zmniejszenie obrzęku tkanki. Działanie techniki wibracyjnej jest podobne do wpływu innego elementu składowego masażu -oklepywania. Wibracja ręczna stosowana jest też w celu drenażu drzewa oskrzelowego IntroductionVibratory massage affects deep sensibility called proprioception. Proprioception is defi ned as a specialised sensibility function covering the sense of the relative position of neighbouring parts of the body, their movement (kinesthesia) and sensing vibration. The receptors providing proprioception -mechanoreceptors -are located in muscles and tendons. They supply the brain with all the information about muscular tonus. Large, spherical Vater-Pacini corpuscles are responsible for vibration sensibility and they are present in deep skin layers, tendons, articular capsules and periosteum. Nervous fi bres are surrounded by multilayer, concentric system of Schwann cells between which tissular liquid is be found [1,2]. Manual vibratory massageManual massage has been known for thousands of years. One of important elements of classical massage is gentle vibration [3]. A massage therapist performs on the skin's surface rapid tapping movements with his/her hand causing vibration in subcutaneous tissues. The vibration technique's effects are similar to another element of massage -percussing. Manual vibration is also used for drainage of the bronchial tree in people with Słowa kluczowe: fi zjoterapia, masaż wibracyjny, trening, rehabilitacja, sport. Masaż wibracyjny dla wspomagania treningu sportowego i fi zjoterapii Abstract:Recently many new devices used for vibratory massage have become available on the Polish market. Manuals usually lack information concerning frequency and intensity of the vibration to be used. Scientifi c papers on application and effects of vibratory massage are hard to fi nd in Polish references. The authors of this paper gathered the available reports on using vibratory massage in sports, biological renewal and physiotherapy.

“…To our knowledge, ours is the first demonstration in humans that learning-induced plasticity is also observed for spatial "where" functions; the electrophysiological manifestations of which can be predicted by pretraining performance measures. In addition to providing insights on the neurophysiological mechanisms of auditory spatial representations, our results open possible training-based neurorehabilitation strategies Spierer et al, 2007) involving repeated training sessions to induce long-lasting effects (Schindler et al, 2002).…”

Auditory spatial representations are likely encoded at a population level within human auditory cortices. We investigated learninginduced plasticity of spatial discrimination in healthy subjects using auditory-evoked potentials (AEPs) and electrical neuroimaging analyses. Stimuli were 100 ms white-noise bursts lateralized with varying interaural time differences. In three experiments, plasticity was induced with 40 min of discrimination training. During training, accuracy significantly improved from near-chance levels to ϳ75%. Before and after training, AEPs were recorded to stimuli presented passively with a more medial sound lateralization outnumbering a more lateral one (7:1). In experiment 1, the same lateralizations were used for training and AEP sessions. Significant AEP modulations to the different lateralizations were evident only after training, indicative of a learning-induced mismatch negativity (MMN). More precisely, this MMN at 195-250 ms after stimulus onset followed from differences in the AEP topography to each stimulus position, indicative of changes in the underlying brain network. In experiment 2, mirror-symmetric locations were used for training and AEP sessions; no training-related AEP modulations or MMN were observed. In experiment 3, the discrimination of trained plus equidistant untrained separations was tested psychophysically before and 0, 6, 24, and 48 h after training. Learning-induced plasticity lasted Ͻ6 h, did not generalize to untrained lateralizations, and was not the simple result of strengthening the representation of the trained lateralizations. Thus, learning-induced plasticity of auditory spatial discrimination relies on spatial comparisons, rather than a spatial anchor or a general comparator. Furthermore, cortical auditory representations of space are dynamic and subject to rapid reorganization.

“…More direct support has been provided by manipulations that aim at modifying the activation balance between the left and right hemispheres, for example by caloric vestibular stimulation (Bottini et al, 2001;Geminiani and Bottini, 1992), neck vibration (Bottini et al, 2001;Schindler et al, 2002), prism adaptation (Saj et al, 2013), or transcranial magnetic stimulation (TMS) (Kim et al, 2013;Muri et al, 2013). These manipulations alleviate neglect symptoms by partly compensating for altered interhemispheric asymmetries in spatial attention, although their effect on early sensory areas remains unresolved (Saj et al, 2013).…”

Recent advances in neurofeedback based on real-time functional magnetic resonance imaging (fMRI) allow for learning to control spatially localized brain activity in the range of millimeters across the entire brain. Realtime fMRI neurofeedback studies have demonstrated the feasibility of self-regulating activation in specific areas that are involved in a variety of functions, such as perception, motor control, language, and emotional processing. In most of these previous studies, participants trained to control activity within one region of interest (ROI). In the present study, we extended the neurofeedback approach by now training healthy participants to control the interhemispheric balance between their left and right visual cortices. This was accomplished by providing feedback based on the difference in activity between a target visual ROI and the corresponding homologue region in the opposite hemisphere. Eight out of 14 participants learned to control the differential feedback signal over the course of 3 neurofeedback training sessions spread over 3 days, i.e., they produced consistent increases in the visual target ROI relative to the opposite visual cortex. Those who learned to control the differential feedback signal were subsequently also able to exert that control in the absence of neurofeedback. Such learning to voluntarily control the balance between cortical areas of the two hemispheres might offer promising rehabilitation approaches for neurological or psychiatric conditions associated with pathological asymmetries in brain activity patterns, such as hemispatial neglect, dyslexia, or mood disorders.
