Mechanical loading influences the lumbar intervertebral disc : A cross‐sectional study in 308 athletes and 71 controls
2021
There is evidence in animal populations that loading and exercise can positively impact the intervertebral disc (IVD). However, there is a paucity of information in humans. We examined the lumbar IVDs in 308 young athletes across six sporting groups (baseball, swimming, basketball, kendo, soccer and running; mean age 19yrs) and 71 non‐athletic controls. IVD status was quantified via the ratio of IVD to vertebral body height (IVD hypertrophy) and ratio of signal intensity in the nucleus to that in the annulus signal (IVD nucleus hydration) on sagittal T2‐weighted MRI. P‐values were adjusted via the false discovery rate method to mitigate false positives. In examining the whole collective, co…
Exercise for the intervertebral disc : a 6-month randomised controlled trial in chronic low back pain
2020
Background context Muscle, bone and tendon respond anabolically to mechanical forces. Whether the intervertebral disc (IVD) can benefit from exercise is unclear. Purpose To examine whether exercise can beneficially affect IVD characteristics. Study design/setting This is a single-blinded 6-month randomised controlled trial (ACTRN12615001270505) in an exercise and physiotherapy clinic. Patient sample Forty patients with chronic non-specific low back pain (NSCLBP) are included in this study. Outcome measures The primary outcome was lumbar IVD T2 time (MRI). Secondary outcomes included IVD diffusion coefficient and IVD expansion with short-duration lying. Methods Twenty patients progressively …
Efectos de la aplicación de un analgésico de mentol previo al entrenamiento de la fuerza muscular sobre parámetros de dolor y capacidad funcional de …
2021
El dolor lumbar crónico (DLC) afecta a más del 30% de los adultos mayores que viven en la comunidad y es la afección musculoesquelética más prevalente en esta población, razón por la cual, se ha transformado en uno de los motivos de consulta más comunes entre las personas mayores quienes se atienden en servicios de atención primaria de salud. Es por esta razón, que el DLC es considerado hoy en día una “epidemia silenciosa” que impacta directamente en la funcionalidad y calidad de vida de las personas mayores con consecuentes costes sanitarios elevados que sobrecargan los sistemas de salud. A este hecho se suma que el origen de este síndrome es multifactorial, con lo cual el diagnóstico es i…

Induction of neuronal plasticity during adulthood. Role of cortical interneurons and plasticity-related molecules.
2019
La complejidad del sistema nervioso de los vertebrados representa un reto a la hora de conocer su funcionamiento. Hace ya más de cien años que se postuló la neurona como unidad básica de procesamiento, generación y transmisión de la información a través de este sistema, y, con el paso de los años, ha evolucionado el conocimiento sobre esta unidad funcional. La idea clásica del sistema nervioso central (SNC) adulto es la de un tejido asombrosamente interconectado y complejo, pero prácticamente inmutable y muy poco adaptable a los cambios. No obstante, esta visión se ha ido desplazando, formándose una nueva idea del SNC adulto que, aunque de manera más limitada que durante el desarrollo, tamb…
Lower thoracic spine extension mobility is associated with higher intensity of thoracic spine pain
2022
Objectives: To evaluate the association of thoracic spine (TS) posture and mobility with TS pain. Methods: Participants with TS pain reported maximum, average, and night pain in TS area, and pain summary score was calculated. Upright and sitting TS postures were evaluated by inspection. TS posture and mobility (flexion and extension) were recorded using an inclinometer and a tape measure, respectively. Correlations between posture and mobility assessments were calculated using Spearman rank correlation, the association of TS posture and mobility with TS pain by logistic regression analysis. Results: The participants’ (n = 73, 52 females, age range 22–56) TS pain duration was 12 weeks on ave…
Remodeling Pattern of Spinal Canal after Full Endoscopic Uniportal Lumbar Endoscopic Unilateral Laminotomy for Bilateral Decompression: One Year Repe…
2022
Objective: There is limited literature on repetitive postoperative MRI and clinical evaluation after Uniportal Lumbar Endoscopic Unilateral Laminotomy for Bilateral Decompression. Methods: Clinical visual analog scale, Oswestry Disability Index, McNab’s criteria evaluation and MRI evaluation of the axial cut spinal canal area of the upper end plate, mid disc and lower end plate were performed for patients who underwent single-level Uniportal Lumbar Endoscopic Unilateral Laminotomy for Bilateral Decompression. From the evaluation of the axial cut MRI, four types of patterns of remodeling were identified: type A: continuous expanded spinal canal, type B: restenosis with delayed expansio…

Datortomogrāfijas protokolu pielietojums kakla traumu gadījumā
2019
Bakalaura darbā ’’Datortomogrāfijas protokolu pielietojums kakla traumu gadījumā’’ tika izvirzīts mērķis: noskaidrot datortomogrāfijas protokolu pielietojumu kakla trauma gadījumā un to kvalitātes ietekmējošos faktorus. Darba teorētiskajā daļā tiek aprakstīta kakla skriemeļa normālā anatomija, fizioloģija, datortomogrāfijas anatomija, kā arī datortomogrāfijas protokolu pielietojums un pareiza pacientu pozicionēšana kvalitātes uzlabošanai un dozas samazināšanai. Darba pētījumā tika izveidota kritēriju tabula un tika izvērtēti 40 datortomogrāfijas kakla skriemeļu izmeklējumi traumu gadījumos. Darbā izmantotās pētniecības metodes – teorētiskās literatūras analīze un kvalitatīvā pētniecības met…
