Identifying Changes in Resilience during Rehabilitation from a Spinal Cord Injury

White, Brian Dale 05 1900 (has links)
The study purposes were to identify changes in resilience, satisfaction with life (SWL), depression, spirituality, and functional independence (FI) and to examine the relationship between these variables, during the inpatient rehabilitation for a spinal cord injury (SCI). The sample included 42 individuals with a SCI, 33 males and 9 females, who were inpatients with a mean stay of 52 days (SD = 15.78). A repeated measures design was employed with questionnaires completed at three times during rehabilitation. Results indicated that there were significant changes in depression, satisfaction with life, spirituality, and FI during inpatient rehabilitation. Findings also indicated significant correlations between resilience, SWL, spirituality, and depression. Future studies developing interventions, and examining factors that predict resilience could help build resilience and may improve rehabilitation outcomes.

Rehabilitation programme to enhance community reintegration for people living with spinal cord injuries in rural areas of Limpopo Province - South Africa

Mohamed, Ehab Elsayed January 2022 (has links)
Thesis (Ph.D. (Health Sciences)) -- University of Limpopo, 2021 / Rehabilitation programmes for PLWSCI aim to give them as much independence as possible and perfect integration at a later stage. Proper rehabilitation involves effective community integration of a person with the SCI. Rehabilitation and community integration are key to return the person with an SCI to play his/her role in the community as an effective, independent, and important person. Globally, PLWSCI are facing numerous barriers and limitations, especially in rural areas, where rehabilitation resources are limited. There is a dearth of rehabilitation centres in the Limpopo Province, which might impact negatively on the rehabilitation and community integration outcomes for PLWSCI in this region. The absence of rehabilitation centres in this province point to the need for the development of extra skills for the professionals who work in the rehabilitation team in this Province. Aim and Objectives The overall aim of this study was to develop a rehabilitation programme to enhance community reintegration for PLWSCI in rural areas of the Limpopo Province, South Africa. Methodology This study used a convergent parallel mixed method design in phase 1. A mixed methodology approach consists of a set of designs and procedures in which both quantitative and qualitative data are collected, analysed, and mixed in a single study. Quantitative data were generated and collected regarding the rehabilitation and community integration challenges of PLWSCI using the Spinal Cord Injury Community Reintegration Measure (SCICRM) tool. Qualitative data were collected through focus group discussions (FGDs). In phase 2 of the study, the Delphi study design was utilised and conducted as a forecasting method based on the results of phase 1. vi Results Quantitative results show that 37% of the respondents were fully reintegrated. Moderate reintegration was above average (54.4%), while 5.7% were minimally integrated, and 3.9% failed to reintegrate into their communities. The rehabilitation teams’ home visits were further rated as “never happened” (51%) and “rarely happened” (14.3%). Patients who received a home visit from their rehabilitation team were more likely to fully reintegrate into their community, in this case, 75%. Of those who did not receive any home visits, only 39% managed to fully reintegrate into their communities. The qualitative findings, which is based on information-rich interviews with participants, indicated an urgent need for the implementation of a rehabilitation programme to enhance a successful and better community reintegration for PLWSCI. The qualitative results also highlighted the importance of home visits and following up on the patients after they have returned to their communities. The qualitative findings were presented according to six themes that were also divided into several sub-themes. In phase 2 of this study, experts agreed that the rehabilitation programme to enhance community integration for people with SCIs in the Limpopo Province should include the identification of the rehabilitation team, distribution of powers between the team members, documentation and referral letters, mobility, assistive devices, sub-acute rehabilitation tasks, home programmes, and the outcome of the successful rehabilitation. Conclusion Rehabilitation is the bridge between the SCI and successful community integration. A comprehensive rehabilitation programme implemented by a multidisciplinary team should enhance the successful reintegration of PLWSCI.

The effectiveness of cognitive-behaviour therapy in improving psychological adjustment to spinal cord injury : a review of the literature

Abdinor, Nicolette Jeanne 03 1900 (has links)
Thesis (MA)--Stellenbosch University, 2004. / ENGLISH ABSTRACT: The traumatic nature of spinal cord injury (SCI) imposes major and permanent life changes that necessitate physical, social and vocational adjustments for the individual, as well as placing strain on the family. The importance of psychological aspects of adjustment and rehabilitation has progressively become recognised as an integral part of facilitating a higher quality of life for individuals and their families living with SCI. While it has been established that psychological disturbance is not an inevitable long-term consequence of SCI, researchers have found that a proportion of this population has marked difficulty adapting psychologically to their new lifestyle and the challenges it poses. It has been found that the SCI population has an increased risk for divorce, substance abuse, self-neglect and suicide. In the mid-1990's, researchers involved in SCI rehabilitation started developing cognitivebehaviour therapy (CBT) interventions to assist individuals with their psychological adjustment to the traumatic injury. Lazarus and Folkman's (1984) cognitive theory of stress and coping has been the theoretical grounding for some of these interventions. The primary objective of this literature review is to ascertain the effectiveness of CBT in assisting individuals with their psychological adjustment to SCI and to make recommendations for future research in this area. / AFRIKAANSE OPSOMMING: Die traumatiese aard van 'n spinale koord besering (SKB) veroorsaak 'n beduidende en permanente lewensverandering, wat fisieke-, sosiale- en werksaanpassing vir die individu verg, asook spanning op die familie plaas. Die belangrikheid van sielkundige aspekte rakende aanpassing en rehabilitasie word toenemend herken as 'n integrale deel in die fasilitering van 'n hoër kwaliteit van lewe vir die individue en hulle families wat lewe met 'n SKB. Alhoewel daar gevind is dat sielkundige versteuring nie 'n noodwendige langtermyn gevolg van 'n SKB is nie, het navorsers wel gevind dat 'n gedeelte van die populasie beduidende sielkundige aanpassingsprobleme ervaar ten opsigte van hul nuwe lewenstyl en uitdagings. Daar is gevind dat die SKB populasie 'n verhoogde risiko loop vir egskeidings, substansmisbruik, self-verwaarlosing en selfmoord. In die middel van die 1990's, het SKB- en rehabilitasie-navorsers kognitiewe-gedragsterapie (KGT) intervensies ontwikkelom individue te help met sielkundige aanpassing na 'n SKB. Lazarus en Folkman's (1984) se kognitiewe teorie oor stres en streshantering, het die teoretiese grondslag gevorm vir sommige van hierdie intervensies. Die primêre doel van hierdie literatuuroorsig is om die effektiwiteit van KGT te bepaal in die ondersteuning van individue met sielkundige aanpassing na SKB, en om voorstelle te maak oor toekomstige navorsing wat met hierdie onderwerp verband hou.

The Role of Injury-related Injustice Perception in Adjustment to Spinal Cord Injury: an Exploratory Analysis

Garner, Ashley Nicole 12 1900 (has links)
Research has begun to explore the presence and role of health-related injustice perceptions in samples of individuals who experience chronic pain associated with traumatic injury. Existing studies indicate that higher level of injustice perception is associated with poorer physical and psychosocial outcomes. However, to date, few clinical populations have been addressed. The aim of the current study was to explore injustice perceptions in a sample of individuals who have sustained a spinal cord injury (SCI), as research suggests that such individuals are likely to experience cognitive elements characteristic of injustice perception (e.g., perceptions of irreparable loss, blame, and unfairness). The study explored the relationship between participants’ level of perceived injustice and several variables associated with outcomes following SCI (depression, pain, and disability) at initial admission to a rehabilitation unit and at three months following discharge. The Injustice Experience Questionnaire was used to measure injustice perceptions. IEQ was found to significantly contribute to depression and anger at baseline. IEQ significantly contributed to depression, present pain intensity, and anger at follow-up. The implication of these preliminary findings may be beneficial for development of future interventions, as many individuals in the United States experience the lifelong physical and psychological consequences of SCI at a high personal and public cost.

Trunk Rehabilitation Using Cable-Driven Robotic Systems

Khan, Moiz Iftikhar January 2019 (has links)
Upper body control is required to complete many daily tasks. One needs to stabilize the head and trunk over the pelvis, as one shifts the center of mass to interact with the world. While healthy individuals can perform activities that require leaning, reaching, and grasping readily, those with neurological and musculoskeletal disorders present with control deficits. These deficits can lead to difficulty in shifting the body center of mass away from the stable midline, leading to functional limitations and a decline in the quality of activity. Often these patient groups use canes, walkers, and wheelchairs for support, leading to occasional strapping or joint locking of the body for trunk stabilization. Current rehabilitation strategies focus on isolated components of stability. This includes strengthening, isometric exercises, hand-eye coordination tasks, isolated movement, and proprioceptive training. Although all these components are evidence based and directly correlate to better stability, motor learning theories such as those by Nikolai Bernstein, suggest that task and context specific training can lead to better outcomes. In specific, based on our experimentation, we believe functional postural exploration, while encompassing aspects of strengthening, hand-eye coordination, and proprioceptive feedback can provide better results. In this work, we present two novel cable robotic platforms for seated and standing posture training. The Trunk Support Trainer (TruST) is a platform for seated posture rehabilitation that provides controlled external wrench on the human trunk in any direction in real-time. The Stand Trainer is a platform for standing posture rehabilitation that can control the trunk, pelvis, and knees, simultaneously. The system works through the use of novel force-field algorithms that are modular and user-specific. The control uses an assist-as-needed strategy to apply forces on the user during regions of postural instability. The device also allows perturbations for postural reactive training. We have conducted several studies using healthy adult populations and pilot studies on patient groups including cerebral palsy, cerebellar ataxia, and spinal cord injury. We propose new training methods that incorporate motor learning theory and objective interventions for improving posture control. We identify novel methods to characterize posture in form of the “8-point star test”. This is to assess the postural workspace. We also demonstrate novel methods for functional training of posture and balance. Our results show that training with our robotic platforms can change the trunk kinematics. Specifically, healthy adults are able to translate the trunk further and rotate the trunk more anteriorly in the seated position. In the standing position, they can alter their reach strategy to maintain the upper trunk more vertically while reaching. Similarly, Cerebral Palsy patients improve their trunk translations, reaching workspace, and maintain a more vertical posture after training, in the seated position. Our results also showed that an Ataxia patient was able to improve their reaching workspace and trunk translations in the standing position. Finally, our results show that the robotic platforms can successfully reduce trunk and pelvis sway in spinal cord injury patients. The results of the pilot studies suggest that training with our robotic platforms and methods is beneficial in improving trunk control.

The rat spinal cord following traumatic injury: An anatomical and behavioural study examining NADPH-d and fos

Allbutt, Haydn January 2004 (has links)
Doctor of Philosophy / The general aim of this current work was to examine spinal cord injury (SCI), and in particular to examine the pathology of injury as it relates to changes in sensory transmission. Due to the limited possibilities for experimentation in humans, a range of animal models of SCI have been developed and are reviewed here. The weight drop SCI model is the most similar to the clinical presentation of SCI in humans and has been widely used in the rat. It was selected for the series of experiments reported in this thesis. Many of the functional deficits produced by SCI result from a cascade of biochemical events set into motion by the injury. Included amongst these is the activation of the enzyme nitric oxide synthase which produces the gaseous neuromodulator, nitric oxide (NO). NO is amongst the most widely distributed and widely utilised molecule in virtually all living organisms, and it is an important signalling molecule in the nervous system. One of the major functions performed by NO appears to relate to sensory transmission, and thus alterations in sensory transmission observed as a result of SCI may involve alterations to NO synthesis. One of the principal aims of this thesis was to examine the effect of SCI on the NO producing cells of the spinal cord and to consider what any changes in NO synthesis may suggest in regards to sensation. NO producing cells were examined using NADPH diaphorase (NADPH-d) histochemistry. As the symptoms of SCI such as motor loss and changes in sensory processing are functional changes, it was also useful to examine changes in neuronal function as a result of SCI. Widespread neuronal function was examined via immunohistochemical detection of the gene product of the immediate early gene, c-fos. It is not known how extensive the biochemical changes resulting from SCI may be, thus another of the aims of the present thesis was to examine the effects of SCI on NO synthesis not only at the level of injury, but also distant to the injury. Findings of the present thesis indicated that traumatic SCI resulted in a decrease in the number of NADPH-d positive cells from the superficial dorsal horn (SDH) of the spinal cord, while the number of these cells are increased in the ventral horn. These changes were restricted to spinal segments adjacent to the injury. Fos expression was also altered by injury and was found to decrease. The most profound changes were found to occur in lamina III, although the other laminae also demonstrated similar changes. Changes in fos expression however were notably more widespread than those for NADPH-d and were not restricted to the level of the injury, occurring at all levels of the spinal cord examined. It was interpreted that alterations in NO synthesis appear to be modulated by the local injury-induced environment while fos expression may be altered by widespread changes to the global level of activity within the central nervous system. Having observed that the number of NADPH-d positive cells of the SDH is reduced following injury, it was of interest to determine whether these cells were in fact killed, or whether they were still present but with reduced NADPH-d activity. Cell counts suggested that the NADPH-d positive cells, which were likely to represent a population of inhibitory interneurons, were not killed following injury, but rather are disrupted such that their normal biochemistry is altered. Since these cells were likely to be inhibitory and were located in laminae involved in sensory transmission, the question arose how disruption of these cells may relate to the neuropathic pain observed to develop following SCI. Thus both NADPH-d and fos expression were again examined, but this time in conjunction with the sensory function of the rats. Sensory thresholds to pain-like behaviour were determined prior to and after injury using Von Frey filaments. Rats that demonstrated a decrease in sensory threshold of at least two Von Frey filament gradations (>70%) were classed as allodynic, while those with a less than a 70% decrease in threshold were classed as non-allodynic. A subpopulation of each of the groups of rats (uninjured, non-allodynic and allodynic) underwent a somatic stimulation paradigm. It was found that stimulation resulted in an increase in the number of NO producing cells but only in the allodynic group of animals. Since this group of animals by definition would perceive this stimulation as noxious, it is likely that the noxious nature of the stimulation resulted in the increased number of NO producing cells observed. This effect occurred only in segments adjacent to the injury. When fos expression was examined in the uninjured animals it was noted that somatic stimulation resulted in a decrease in fos expression, almost exclusively in lamina III. Following injury, there was no change in fos expression in lamina III observed. Instead the only change observed was an increase in fos expression in the deep dorsal horn (DDH, lamina IV and V). This occurred most profoundly in the allodynic group. These results suggested that SCI may lead to misprocessing of sensory signals such that non-noxious somatic stimuli are processed in the DDH rather than lamina III following SCI. It is proposed here that this change in laminae processing may be responsible for the perception of pain towards a non-noxious stimulus, and that the reported injury-induced loss of NO producing inhibitory interneurons in the SDH may be responsible for this alteration in sensory processing following SCI. Sensation is also processed by a number of supraspinal structures and a number of these have been implicated in the development of neuropathic pain states. The effects of SCI on neuronal activity as well as NO synthesis were examined in the periaqueductal grey region of the mid brain (PAG). SCI was shown to result in reduced neuronal activity in the PAG. This reduction in activity did not follow the somatotopy of the lateral column of the PAG (lPAG). It was suggested the reduced activity may not be solely caused by reduced spinal input as a result of SCI. Reduced neuronal activity in the PAG may indicate reduced PAG function, which includes descending modulation of spinal sensory transmission. Injury was not found to alter NADPH-d expression in the PAG. The effect of traumatic lumbar SCI on the parietal (sensorimotor) cortex of the rat was also examined, as loss of inputs following SCI have been shown to result in a profound reorganisation of the cortex. Results indicated that SCI results in a virtual cessation of neuronal activity in areas 1 and 2 of the parietal cortex, likely as a result of lost afferent drive. Theories of cortical plasticity suggest that while the primary inputs via the lumbar spinal cord may be lost following SCI, other less dominants input will remain and become more dominant. It has been proposed previously that cortical reorganisation involves a rapid reorganisation of the entire sensory system. It was interpreted that a similar process may explain the system-wide reduction in neuronal activity observed in the present series of studies.

A comparison of bone mineral density between active and nonactive men with spinal cord injuries

Eddins, William C. 28 June 1994 (has links)
The purpose of this study was to compare the levels of bone mineral density (BMD) of the whole body (WB) and proximal femurs of physically active men with spinal cord injuries (SCI) to nonactive men with spinal cord injuries. Also, the lean muscle mass (LMM) of active men with SCI was compared to the LMM of nonactive men with SCI. In addition, BMD values of the radii of physically active men with SCI were compared to that of able bodied men of the same age. The subjects N. 46 were between the age of 20-55 (��=37.83 �� 6.63 years), and were at least 2 years post spinal cord injury. Subjects with SCI were matched on similar level of lesion of the spinal cord, age, height, weight, and years post injury for the purpose of analyzing data. There were 14 active men with paraplegia and 14 nonactive men with paraplegia, 9 active men with quadriplegia and 9 nonactive men with quadriplegia. All BMD data was obtained utilizing a Hologic QDR 1000W dual energy x-ray absorptiometer. A two-factor (level by group) analysis of variance revealed no significant difference for all sites (Whole body, Total hip, radii, LMM) comparing the active and nonactive men with SCI. T-scores and z-scores generated from the Ho logic QDR 1000/W were analyzed using two-factor ANOVA (level by group). The active men with paraplegia had significantly higher BMD levels for all sites when compared to the other groups. These values may be explained by the number of incomplete injuries in the experimental group. Subjects in the physically active group did not clearly show a statistically significant difference on any of the dependent measures. However, values for the dependent measures were higher for the physically active group compared to the values of the nonactive group. / Graduation date: 1995
