The effect of transient visual deprivation on motor cortical excitability and motor learning : a pilot study
2016
Castro, Fabio, 2015. The Effect of Transient Visual Deprivation on Motor Cortical Excitability and Motor Learning. University of Jyväskylä, Department of Biology of Physical Activity, Master Thesis in Applied Biomechanics. 86 pp. We devised an experimental protocol to test the hypothesis that if the performer poses attention on the proprioceptive signals, in the form of awareness of the body in space, this could increase the corticospinal excitability and the overall performance. 10 right-handed volunteers were randomly assigned to either a group performing a skill training blindfolded (BLIND) or in normal (NORM) condition. The intervention included a visuomotor task-related skill training …
Non-stationary nature of SO2 degassing at Etna’s North-east crater (Italy).
2012
Investigating Etna’s long-term SO2 flux behaviour has led to important conclusions on the structure of the volcano’s magma feeding system, magma production (and degassing) rates, and causes for the excess degassing behaviour. Nonetheless, our knowledge of the short-term (timescales of seconds to a few hours) behaviour of magmatic volatiles (e.g., bubble coalescence, separate ascent and surface bursting of gas-rich bubbles) in the volcano’s upper feeding conduit system is still fragmentary, and based on indirect evidences (petrologic-textural data, observation of geophysical signals , physical modelling and laboratory experiments). In the past, direct gas flux measurements at Etna have been ta…
El hilo rojinegro. Experiencias libertarias en la España posfranquista (València, c. 1968-1990)
2018
Esta investigación se centra en el movimiento libertario en la España posfranquista. Para ello he realizado una serie de entrevistas bajo el formato de historia de vida a unas cuarenta personas que participaron en las diferentes vertientes del movimiento. Las he localizado, además, en un espacio concreto, la ciudad de València, durante las décadas de 1970 y 1980. La aproximación que ofrezco en estas páginas es, por tanto, una lectura interpretativa a través de la memoria de lxs entrevistadxs, tanto de la historia del anarquismo en esos años como del significado de la «transición» a la democracia y la consolidación de esta en la España postdictatorial. ¿Qué aportan la(s) «experiencia(s) libe…

Introducción: La fibromialgia (FM) es un síndrome complejo que se caracteriza por dolor crónico difuso y generalizado en el sistema musculoesquelético, acompañado de otros síntomas, tales como fatiga, alteraciones del sueño, parestesias y rigidez articular. Estos síntomas provocan una disminución de la capacidad funcional y, en consecuencia, de la calidad de vida de la persona afectada. En este síndrome también se ven alteradas la dimensión emocional en aspectos como la ansiedad, depresión y estrés. La manifestación clínica más común que presentan las personas que sufren FM es el dolor, con una disminución de su umbral, acompañado de hiperalgesia y alodinia. Estas características se han rel…
A comparison of lumbopelvic motion patterns and erector spinae behavior between asymptomatic subjects and patients with recurrent low back pain durin…
2015
Objectives: The purpose of this study was to determine the patterns of lumbopelvic motion and erector spinae (ES) activity during trunk flexion-extension movements and to compare these patterns between patients with recurrent low back pain (LBP) in their pain-free periods and matched asymptomatic subjects. Methods: Thirty subjects participated (15 patients with disc herniation and recurrent LBP in their pain-free periods and 15 asymptomatic control subjects). A 3-dimensional videophotogrammetric system and surface electromyography (EMG) were used to record the angular displacements of the lumbar spine and hip in the sagittal plane and the EMG activity of the ES during standardized trunk fle…
Transverse fracture-dislocation of the sacrum: a diagnostic pitfall and a surgical challenge.
2002
Transverse fracture-dislocations of the sacrum are rare. Associated lesions of the lumbosacral spine as well as neurological injuries are common. Conventional radiographs of the pelvis often fail to clearly visualize the fracture. Delayed diagnosis increases the risk of progressive neurological disfunction. True lateral sacral views and CT-scans with 3-dimensional reconstructions are very helpful in establishing the full extent of the injury. These examinations should be considered in all patients with a history of high energy trauma and clinical signs indicating lumbosacral injury, such as severe low back pain and neurological disturbances of the lower extremities. The management of transv…
Effects of pregnancy on lumbar motion patterns and muscle responses.
2018
The kinematics of the lumbar region and the activation patterns of the erector spinae muscle have been associated with the genesis of low back pain, which is one of the most common complications associated with pregnancy. Despite the high prevalence of pregnancy-related low back pain, the biomechanical adaptations of the lumbar region during pregnancy remain unknown.This study analyzes lumbar spine motion and the activation pattern of the lumbar erector spinae muscle in healthy pregnant women.A case-control study.The study involved 34 nulliparous women (control group) and 34 pregnant women in the third trimester (week 36 ± 1).We recorded the parameters of angular displacement of the lumbar …
Bone Mass Distribution in the Sacrum
2017
The trabecular architecture and bone mass distribution of each bone follows biomechanical principles and is an adaption to the stress exhibited during lifetime. In patients with osteoporosis, the bone mass decreases and the bone microarchitecture changes. A distinct bone mass distribution in non-osteoporotic and osteoporotic individuals is demonstrated using statistical modelling in the sacrum. The authors studied the sacral bone mass distribution using a 3D statistical model based on clinical CT scans of 92 Europeans. In the group with worse general bone mass (less than 100 Houndsfeld Units (HU) measured in the body of L5), there were large areas of negative HU in the sacral alae. These “a…
