Experimental validation of the prosthetic leg
2020
Abstract Studies of populations whose ability to perform voluntary movements is impaired due to natural reasons (e.g. aging), genetic anomaly (e.g. Down syndrome), trauma (e.g. spinal cord injury, amputation) or illness (e.g. Parkinson’s disease) frequently result in a basic question: are the observed motor patterns, which may be rather different from those seen in the general population, actually abnormal? In other words, should they be corrected? This question is important, not only for understanding the mechanisms of control over normal and disordered movements, but also for assessing the effectiveness of existing therapeutic approaches and providing focus for developing new therapies an…
Supporting Diagnosis and Treatment of Scoliosis: Using Augmented Reality to Calculate 3D Spine Models in Real-Time - ARScoliosis
2020
Scoliosis is a complex spinal disorder that mostly affects adolescents and younger population. To avoid and reduce harmful radiation techniques in adolescent idiopathic scoliosis investigation and follow-ups, a novel non-invasive approach is highly recommended and needed in clinical practice. In this paper ARScoliosis application to diagnose, visualize and document spinal condition and particularly adolescent idiopathic scoliosis in real time is presented. This ARScoliosis application is developed in Unity 3D, a game engine, and allows non-invasive quantification of posture and spinal deformity using recently available non-ionizing wide-angle depth sensor Microsoft Azure Kinect DK as a diag…
Learning Curve in Surgical Treatment of Odontoid Fixation for a Series of Type II C2 Fractures
2019
The craniovertebral junction (CVJ) is a complex anatomical area upon which most of the motion of the upper cervical spine depends [1]. Because of its unique range of motion, the CVJ is subject to several types of traumatic injury; it has been shown that odontoid fractures are the most common ones in the general population and are the most common isolated spinal fractures [2]. Accounting for up to 18% of all cervical fractures, odontoid fractures are the most common ones in elderly patients [3], in whom they account for up to 60% of spinal cord injuries [4].
Influence of nerve growth factor in endometriosis-associated symptoms
2011
To investigate the role of the nerve growth factor (NGF) in the development of dysmenorrhea/pelvic pain in patients with endometriosis, we performed a prospective, clinical, blind study. Peritoneal fluids (PFs) were obtained from patients with histologically proven endometriosis. Patients with endometriosis were divided into 7 different groups depending on their preoperative pain score and symptomatology: patients with no pain, patients with minimal pain (dysmenorrhea, pelvic pain, or both), and patients with severe pain (dysmenorrhea, pelvic pain, or both) and were used for the neuronal growth assay with cultured chicken dorsal root ganglia (DRG) and for Western blot analyses. Dorsal root …
Endovascular treatment for chronic cerebrospinal venous insufficiency: is the procedure safe?
2010
Objectives The aim of this report is to assess the safety of endovascular treatment for chronic cerebrospinal venous insufficiency (CCSVI). Although balloon angioplasty and stenting seem to be safe procedures, there are currently no data on the treatment of a large group of patients with this vascular pathology. Methods A total of 564 endovascular procedures (balloon angioplasty or, if this procedure failed, stenting) were performed during 344 interventions in 331 CCSVI patients with associated multiple sclerosis. Results Balloon angioplasty alone was performed in 192 cases (55.8%), whereas the stenting of at least one vein was required in the remaining 152 cases (44.2%). There were no majo…
Estudio de la afectación medular en la Esclerosis Múltiple. Establecimiento de patrones de lesión en neuroimagen y su relación con la discapacidad.
2015
La Esclerosis Múltiple (EM) es una enfermedad de evolución muy variable sin factores pronósticos de discapacidad claramente definidos. La médula espinal es una localización relevante para el desarrollo de discapacidad física en los pacientes con EM. Por su estructura, es esperable que sea clínicamente elocuente; sin embargo, en la EM es frecuente encontrar afectación medular silente por resonancia magnética (RM), siendo relevante para el diagnóstico de la enfermedad, pero su relación con el desarrollo de la discapacidad no se ha demostrado claramente, lo cual contribuye a la disociación clínico-radiológica de esta enfermedad. La RM es la herramienta diagnóstica más sensible en la EM. El uso…
Influencia de la fatiga en la calidad de movimiento de personas con lesión medular
2017
La fatiga es un fenómeno fisiológico complejo por el que se limita la capacidad del individuo para mantener una actividad física concreta (Bigland-Ritchie y Woods, 1984). En individuos sanos el desarrollo de la fatiga está ligado al ejercicio físico siendo la causa principal que limita la duración del mismo. Además, la fatiga aparece como parte de la patología de diferentes enfermedades y su efecto es igualmente limitador de la actividad física. El estudio de un fenómeno tan complejo se ha realizado con distintos abordajes experimentales y en distintos niveles fisiológicos con individuos sanos, lo que ha permitido distinguir tres tipos básicos de fatiga: a) fatiga periférica, producida en e…
Standards for the diagnosis and management of complex regional pain syndrome: Results of a European Pain Federation task force.
2019
Background: Complex regional pain syndrome is a painful and disabling post-traumatic primary pain disorder. Acute and chronic complex regional pain syndrome (CRPS) are major clinical challenges. In Europe, progress is hampered by significant heterogeneity in clinical practice. We sought to establish standards for the diagnosis and management of CRPS. Methods: The European Pain Federation established a pan-European task force of experts in CRPS who followed a four-stage consensus challenge process to produce mandatory quality standards worded as grammatically imperative (must-do) statements. Results: We developed 17 standards in 8 areas of care. There are 2 standards in diagnosis, 1 in multi…

Valoración biomecánica de la columna vertebral basada en el análisis funcional de diversas actividades de la vida diaria
2018
En la literatura se han utilizado pruebas dinámicas sobre movimientos sencillos, como la flexo-extensión del tronco o la marcha, para distinguir de manera objetiva entre sujetos sanos y pacientes con dolor lumbar de causa inespecífica. No tenemos constancia de estudio alguno que haya registrado de manera simultánea los patrones de actividad neuromuscular de la musculatura extensora de la espalda, musculatura abdominal, glúteos e isquiotibiales y los patrones de movimiento lumbo-pélvico, estudiando el efecto de la velocidad y carga, mediante técnicas no invasivas durante actividades de la vida diaria, y los haya comparado entre distintos grupos de pacientes con dolor lumbar y alteraciones es…
