‘It’s not a part of me, but it is what it is’: the struggle of becoming en-wheeled after spinal cord injury
2019
Many people who experience spinal cord injury become long-term wheelchair users. This article addresses the process of becoming en-wheeled through the case example of a disabled man called Patrick.An intrinsic case study informed by posthumanist developments was used. Within this design, Patrick and his manual wheelchair were the entangled participants of the inquiry.Interviews and fieldwork observation with Patrick were conducted. Qualitative data were analysed using the posthumanist notion of 'assemblages'.The results illuminate Patrick's struggle of negotiating a new embodied selfhood that includes the wheelchair. Patrick engaged in ableist rehabilitation after spinal cord injury to recu…
Pharmacological Suppression of CNS Scarring by Deferoxamine Reduces Lesion Volume and Increases Regeneration in an In Vitro Model for Astroglial-Fibr…
2015
Lesion-induced scarring is a major impediment for regeneration of injured axons in the central nervous system (CNS). The collagen-rich glial-fibrous scar contains numerous axon growth inhibitory factors forming a regeneration-barrier for axons. We demonstrated previously that the combination of the iron chelator 2,2'-bipyridine-5,5'-decarboxylic acid (BPY-DCA) and 8-Br-cyclic AMP (cAMP) inhibits scar formation and collagen deposition, leading to enhanced axon regeneration and partial functional recovery after spinal cord injury. While BPY-DCA is not a clinical drug, the clinically approved iron chelator deferoxamine mesylate (DFO) may be a suitable alternative for anti-scarring treatment (A…
Impact of COVID-19 on the self-reported physical activity of people with complete thoracic spinal cord injury full-time manual wheelchair users
2021
Coronavirus SARS-CoV-2; COVID-19; 2019-nCoV; Activitat física; Lesió medul·lar Coronavirus SARS-CoV-2; COVID-19; 2019-nCoV; Actividad física; Lesión de la médula espinal Coronavirus SARS-CoV-2; COVID-19; 2019-nCoV; Physical activity; Spinal cord injury Context The emergence of COVID-19 caused a new public health crisis, leading to major changes in daily life routines, often including physical activity (PA) levels. The main goal of this study was to analyze the differences in self-reported physical activity of people with complete spinal cord injuries between the time prior to the COVID-19 lockdown and the lockdown period itself. Methods A sample of 20 participants with complete thoracic spi…
Transplanted neural stem/precursor cells instruct phagocytes and reduce secondary tissue damage in the injured spinal cord
2012
Transplanted neural stem/precursor cells possess peculiar therapeutic plasticity and can simultaneously instruct several therapeutic mechanisms in addition to cell replacement. Here, we interrogated the therapeutic plasticity of neural stem/precursor cells after their focal implantation in the severely contused spinal cord. We injected syngeneic neural stem/precursor cells at the proximal and distal ends of the contused mouse spinal cord and analysed locomotor functions and relevant secondary pathological events in the mice, cell fate of transplanted neural stem/precursor cells, and gene expression and inflammatory cell infiltration at the injured site. We used two different doses of neural…
Heart rate variability in individuals with thoracic spinal cord injury
2014
Cross-sectional study. The main goal of our study was to explore the differences in heart rate variability (HRV) while sitting between able-bodied (AB) participants and paraplegic (P) individuals. The study was conducted in the Physical Therapy department and the Physical Education and Sports department of the University of Valencia and Vall d’Hebron Hospital. To record the HRV, a 1000-Hz Suunto Oy t6 heart rate monitor was used. The data were analyzed in the temporal and frequency domains, and nonlinear analysis was performed as well. We found significant differences between P and AB participants in SDNN: t(76)=2.81, P<0.01; root mean squared of the difference of successive RR intervals: t…
Cellular Response to Spinal Cord Injury in Regenerative and Non-Regenerative Stages in Xenopus Laevis
2020
Abstract Background The efficient regenerative abilities at larvae stages followed by a non-regenerative response after metamorphosis in froglets makes Xenopus an ideal model organism to understand the cellular responses leading to spinal cord regeneration. Methods We compared the cellular response to spinal cord injury between the regenerative and non-regenerative stages of Xenopus laevis. For this analysis, we used electron microscopy, immunofluorescence and histological staining of the extracellular matrix. We generated two transgenic lines: i) the reporter line with the zebrafish GFAP regulatory regions driving the expression of EGFP, and ii) a cell specific inducible ablation line with…
Risk factors in iatrogenic spinal cord injury
2017
Study design: In the last years, there has been a change in the aetiology of spinal cord injury. There has been an increase in the number of elderly patients with spinal cord injuries caused by diseases or medical procedures. Objective: The aim of this study is to investigate the frequency of the occurrence of iatrogenic spinal cord injury in our unit. The secondary aim is to study what variables can be associated with a higher risk of iatrogenesis. Methods: A retrospective, descriptive, observational study of patients with acute spinal cord injury admitted from June 2009 to May 2014 was conducted. The information collected included the patient age, aetiology, neurological level and grade o…
Selkäydinvammaisten henkilöiden toimintakyvyn itsearviointi Suomessa
2021
Selkäydinvamma vaikuttaa laajasti arjessa toimimiseen sekä muihin elämän eri osa-alueisiin. Selkäydinvammaisten henkilöiden toimintakykyä ei ole tutkittu Suomessa laajasti. Selkäydinvammaisille kohdennettujen toimintakykymittareiden valikoima on suppea ja niiden pätevyys vaihtelee. Selkäydinvammaisen henkilön toimintakyvyn itsearviointimittari (The Spinal Cord Independence Measure- Self Report: SCIM-SR) on kehitetty tarkastelemaan juuri selkäydinvammaisten henkilöiden toimintakykyä selkäydinvammaan liittyvissä asioissa. Mittari painottuu fyysisen toimintakyvyn ulottuvuuksiin. SCIM-SR-mittari pisteyttää toimintakykyä siten, että 100 pistettä on maksimi ja samalla paras toimintakyky. Kolmen a…
Adaptation and validation of the Spanish self-report version of the Spinal Cord Independence Measure (SCIM III).
2014
Study design: This is a cross-sectional validation study. Objective: The objective of this study was to adapt and validate a self-report version of the Spinal Cord Independence Measure (SCIM III) for the Spanish population. Methods: A cross-cultural adaptation of the self-report version of the SCIM III for the Spanish population was performed on the basis of international guidelines. A total of 100 patients with spinal cord injury (SCI) were recruited. A team of healthcare professionals administered the SCIM III by observation. In addition, the patients completed the Spanish self-report version (eSCIM-SR). Data from both questionnaires were analysed jointly. Results: A high correlation was …
Use of Machine Learning and Artificial Intelligence to Drive Personalized Medicine Approaches for Spine Care
2020
Personalized medicine is a new paradigm of healthcare in which interventions are based on individual patient characteristics rather than on “one-size-fits-all” guidelines. As epidemiological datasets continue to burgeon in size and complexity, powerful methods such as statistical machine learning and artificial intelligence (AI) become necessary to interpret and develop prognostic models from underlying data. Through such analysis, machine learning can be used to facilitate personalized medicine via its precise predictions. Additionally, other AI tools, such as natural language processing and computer vision, can play an instrumental part in personalizing the care provided to patients with …
