Kinematics and kinetics analysis of midfoot joints of 30 normal subjects during walking

2016

Abstract Introduction There is not enough evidence in form of clinical studies regarding the behavior of the midfoot joints in dynamic situations such us walking or running. The present work aims to study the mechanical behavior of midfoot joints with a multisegmented foot model with special interest in joint moments and their clinical significance. Subjects and methods A computerized 3-dimensional gait study was performed on healthy male adult subjects with a neutral Foot Posture Index (FPI) (from 0 to +5) during walking. Joint angle and external moments were estimated with a multisegment foot model that considers three separate segments (forefoot, rearfoot and hallux) and graphs and value…

Kinematics of the patellofemoral joint. Investigations on a computer model with reference to patellar fractures.

1990

Patellofemoral kinematics were studied on a computer model. The articulating point of the patella moves from distal to proximal during flexion, until the quadriceps tendon starts to turn around the femur tendo-femoral gliding. The pattern of patellofemoral movement consists of a gliding and rolling component, the latter at its maximum at the beginning of flexion. The pathway of the instant centers of motion moves from dorsal to ventral during flexion. Stress analysis shows that the contact area is at all times the area of maximum bending stress. The distal part of the patella is the part with mechanical stress at all angles of flexion. The conclusions to be drawn for treatment are that frac…

Performing in concert and in rehearsal - a comparison using audio, video and movement data

2009

As a musician it is clear that a concert performance involves a specific engagement. Both the physical attitude and the musical expression change through the interaction with the public. However, the mechanisms involved in this interaction are not well documented. To study the influence of the public on performance, a concert with a singer and a viola da gamba player was recorded using audio, video and acceleration sensors (invisibly) attached to wrists and back of the performers. These data were compared to the general rehearsal, recorded in identical settings. This enables a scientifically valid comparison, without challenging the ecological validity. General rehearsal and concert perform…

Brain and body percussion : the relationship between motor and cognitive functions

2015

The focus of this thesis is the relationship between embodied motor rhythmic exercises (e.g. body percussion) and executive functions. Decades’ long successful application of this method within general classrooms and in music education led to the hypothesis that body percussion could have a positive impact on core cognitive functions also referred to as executive functions. Two pilot experiments were conducted to test proper settings for investigating the above-mentioned relationship. Experiment 1 piloted the use of neuropsychological tests with pre- and post-measures of the Tower of London (TOL) neuropsychological test. Experiment 2 piloted the use of an electroencephalography (EEG) device…

Chinese Peoples and the Others : Notes on Contemporary Chinese Nationalism and the May Fourth Movement

2019

The May Fourth Movement (1917-1921) has always been an important part of the official historical narrative of the Chinese Communist Party. Today, the Movement is often celebrated as being closely connected with the emergence of modern Chinese patriotism and nationalism in contemporary China. In the 21st century, Chinese nationalism has voiced more assertive overtones with a tendency to glorify Chinese imperial history. What is more, contemporary Chinese nationalism often adopts a negative attitude towards foreign ideas and thought trends. This article discusses the differences between contemporary Chinese nationalism and the May Fourth Movement nationalism by examining the argumentation str…

Artificial faces predict gaze allocation in complex dynamic scenes

2019

Both low-level physical saliency and social information, as presented by human heads or bodies, are known to drive gaze behavior in free-viewing tasks. Researchers have previously made use of a great variety of face stimuli, ranging from photographs of real humans to schematic faces, frequently without systematically differentiating between the two. In the current study, we used a Generalized Linear Mixed Model (GLMM) approach to investigate to what extent schematic artificial faces can predict gaze when they are presented alone or in competition with real human faces. Relative differences in predictive power became apparent, while GLMMs suggest substantial effects for real and artificial f…

Negative emotional state slows down movement speed : behavioral and neural evidence

2019

Background Athletic performance is affected by emotional state. Athletes may underperform in competition due to poor emotion regulation. Movement speed plays an important role in many competition events. Flexible control of movement speed is critical for effective athletic performance. Although behavioral evidence showed that negative emotion can influence movement speed, the nature of the relationship remains controversial. Thus, the present study investigated how negative emotion affects movement speed and the neural mechanism underlying the interaction between emotion processing and movement control. Methods The present study combined electroencephalography (EEG) technology with a cued-…

Feminisme neoliberal: un oxímoron?

2018

Neoliberal Feminism: An Oxymoron? Resum: En el present escrit tractem d’aproximar-nos al concepte de “feminisme neoliberal” per tal d’identificar-ne les principals caracteristiques i contradiccions. Aixi doncs, l’objectiu principal que ens plantegem tracta de discernir si es possible, atenent al context actual de desenvolupament del moviment feminista en un marc neoliberal, parlar de “feminisme neoliberal”, o si pel contrari, es tracta d’un concepte que es en si mateix un oximoron. Partint del sentit de transformacio social cap a la justicia intrinsec al moviment feminista, tractarem de veure com la logica neoliberal ha condicionat o influenciat en aquest moviment en l’actualitat. Alhora es…

Transcranial Magnetic Stimulation and Neuroimaging Coregistration

2013

The development of neuroimaging techniques is one of the most impressive advancements in neuroscience. The main reason for the widespread use of these instruments lies in their capacity to provide an accurate description of neural activity during a cognitive process or during rest. This important advancement is related to the possibility to selectively detect changes of neuronal activity in space and time by means of different biological markers. Specifically, functional magnetic resonance imaging (fMRI), positron emission tomography (PET), single-photon emission computed tomography (SPECT), and nearinfrared spectroscopy (NIRS) use metabolic markers of ongoing neuronal activity to provide a…
