The effects of physiotherapy using proprioceptive neuromuscular facilitation techniques on the gait of patients after hip and knee arthroplasty: a ca…
2021
Background: Gait disturbances are a major problem for patients after arthroplasty. After the surgery, walking speed, the rhythm of locomotion, and the length of the steps are significantly reduced. One of the therapeutic methods used in gait re-education is proprioceptive neuromuscular facilitation (PNF). Aim of the study: This study aimed to evaluate the effects of physiotherapy using PNF techniques on the gait of patients after hip and knee arthroplasty. Case report: A 60-year-old woman with advanced osteoarthritis that received bilateral hip and right knee arthroplasties was examined. Before and after the therapy, the following tests were performed: measurement of the range of motion (RO…
Chapter 31 Transcranial magnetic stimulation studies of contralesional space attention deficits
2002
Publisher Summary The power of transcranial magnetic stimulation (TMS) to disrupt and modulate the neural activity in focal brain regions has provided researchers in this field a promising tool to empirically test specific neuropsychological models and constructs of contralesional space attention deficits. A group of studies has used TMS to transiently disrupt the cortical activity of the focal brain areas in normal subjects to replicate the effects of neurological lesions. This chapter discusses a number of studies, using single-pulse, paired-TMS, and repetitive TMS (rTMS) and different experimental paradigms that show how this technique can be of fundamental importance, in elucidating the…
On application of kernel PCA for generating stimulus features for fMRI during continuous music listening
2018
Background There has been growing interest towards naturalistic neuroimaging experiments, which deepen our understanding of how human brain processes and integrates incoming streams of multifaceted sensory information, as commonly occurs in real world. Music is a good example of such complex continuous phenomenon. In a few recent fMRI studies examining neural correlates of music in continuous listening settings, multiple perceptual attributes of music stimulus were represented by a set of high-level features, produced as the linear combination of the acoustic descriptors computationally extracted from the stimulus audio. New method fMRI data from naturalistic music listening experiment were…
Connectivity Patterns During Music Listening: Evidence for Action-Based Processing in Musicians
2017
Musical expertise is visible both in the morphology and functionality of the brain. Recent research indicates that functional integration between multi-sensory, somato-motor, default-mode (DMN), and salience (SN) networks of the brain differentiates musicians from non-musicians during resting state. Here, we aimed at determining whether brain networks differentially exchange information in musicians as opposed to non-musicians during naturalistic music listening. Whole-brain graph-theory analyses were performed on participants' fMRI responses. Group-level differences revealed that musicians' primary hubs comprised cerebral and cerebellar sensorimotor regions whereas non-musicians' dominant …
Dynamic Functional Connectivity in the Musical Brain
2019
Musical training causes structural and functional changes in the brain due to its sensory-motor demands. This leads to differences in how musicians perceive and process music as compared to non-musicians, thereby providing insights into brain adaptations and plasticity. Correlational studies and network analysis investigations have indicated the presence of large-scale brain networks involved in the processing of music and have highlighted differences between musicians and non-musicians. However, studies on functional connectivity in the brain during music listening tasks have thus far focused solely on static network analysis. Dynamic Functional Connectivity (DFC) studies have lately been …
Brain integrative function driven by musical training during real-world music listening
2017
The present research investigated differences in the brain dynamics of continuous, real-world music listening between listeners with and without professional musical training, using functional magnetic resonance imaging (fMRI). A replication study was aimed at validating the reliability of the naturalistic approach to studying brain responses to music, wherein the brain signal and the acoustic information extracted from the musical stimulus were correlated. After a successful replication, a series of three studies dealt with differences in integrative brain function during music listening between musicians and nonmusicians. Findings (a) emphasized the crucial role of the distinctive postura…
Paradigma pragmático-funcional en la rehabilitación de la afasia
2020
Durante las últimas dos décadas, la investigación sobre la rehabilitación de la afasia ha desarrollado una visión pragmática y funcional del lenguaje, lo que ha llevado a una orientación cada vez más multifacética del trabajo terapéutico. En este enfoque pragmático-funcional de la rehabilitación de la afasia convergen diferentes programas concebidos de forma independiente, centrando la terapia en la dimensión relacional del lenguaje, que incluye: las interrelaciones funcionales entre los componentes del sistema lingüístico; la función comunicativa y el uso del lenguaje en contextos naturales como las conversaciones cotidianas; las interrelaciones entre el comportamiento verbal y otros medio…

Associations of physical performance and physical activity with mental well-being in middle-aged women
2021
Abstract Background To investigate whether physical performance is independently of physical activity (PA) associated with positive and negative dimensions of mental well-being in middle-aged women. Methods Data were drawn from the Estrogenic Regulation of Muscle Apoptosis (ERMA) study in which women 47 to 55 years were randomly selected from the Finnish National Registry. They (n = 909) participated in measurements of physical performance (handgrip force, knee extension force, vertical jumping height, maximal walking speed, and six-minute walking distance). Both mental well-being (the Centre for Epidemiologic Studies Depression Scale, the International Positive and Negative Affect Schedule…
