Willits AB, Kader L, Eller O, Roberts E, Bye B, Strope T, Freudenthal BD, Umar S, Chintapalli S, Shankar K, Pei D, Christianson J, Baumbauer KM, Young EE. Spinal cord injury-induced neurogenic bowel: A role for host-microbiome interactions in bowel pain and dysfunction. NEUROBIOLOGY OF PAIN (CAMBRIDGE, MASS.) 2024; 15:100156. [PMID: 38601267 PMCID: PMC11004406 DOI: 10.1016/j.ynpai.2024.100156] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 02/02/2024] [Revised: 04/04/2024] [Accepted: 04/04/2024] [Indexed: 04/12/2024]
Abstract
Background and aims Spinal cord injury (SCI) affects roughly 300,000 Americans with 17,000 new cases added annually. In addition to paralysis, 60% of people with SCI develop neurogenic bowel (NB), a syndrome characterized by slow colonic transit, constipation, and chronic abdominal pain. The knowledge gap surrounding NB mechanisms after SCI means that interventions are primarily symptom-focused and largely ineffective. The goal of the present studies was to identify mechanism(s) that initiate and maintain NB after SCI as a critical first step in the development of evidence-based, novel therapeutic treatment options. Methods Following spinal contusion injury at T9, we observed alterations in bowel structure and function reflecting key clinical features of NB. We then leveraged tissue-specific whole transcriptome analyses (RNAseq) and fecal 16S rRNA amplicon sequencing in combination with histological, molecular, and functional (Ca2+ imaging) approaches to identify potential mechanism(s) underlying the generation of the NB phenotype. Results In agreement with prior reports focused on SCI-induced changes in the skin, we observed a rapid and persistent increase in expression of calcitonin gene-related peptide (CGRP) expression in the colon. This is suggestive of a neurogenic inflammation-like process engaged by antidromic activity of below-level primary afferents following SCI. CGRP has been shown to disrupt colon homeostasis and negatively affect peristalsis and colon function. As predicted, contusion SCI resulted in increased colonic transit time, expansion of lymphatic nodules, colonic structural and genomic damage, and disruption of the inner, sterile intestinal mucus layer corresponding to increased CGRP expression in the colon. Gut microbiome colonization significantly shifted over 28 days leading to the increase in Anaeroplasma, a pathogenic, gram-negative microbe. Moreover, colon specific vagal afferents and enteric neurons were hyperresponsive after SCI to different agonists including fecal supernatants. Conclusions Our data suggest that SCI results in overexpression of colonic CGRP which could alter colon structure and function. Neurogenic inflammatory-like processes and gut microbiome dysbiosis can also sensitize vagal afferents, providing a mechanism for visceral pain despite the loss of normal sensation post-SCI. These data may shed light on novel therapeutic interventions targeting this process to prevent NB development in patients.

Abstract
During the Cybathlon Global Edition 2020, athletes compete in a Functional Electrical Stimulation (FES) bike race. In this event, athletes with a spinal cord injury cover a distance of 1200 m on an adapted bike by using electrostimulation to activate their leg muscles in order to evoke a pedalling movement. This report reviews the training regimen, as designed by the PULSE Racing team, and the experience of one athlete in preparation for the Cybathlon Global Edition 2020. The training plan was designed to vary exercise modes in order to optimize physiological adaptations and minimize monotony for the athlete. Additional constraints due to coronavirus pandemic, e.g., postponement of the Cybathon Global Edition and modification from a live cycling track to a virtual stationary race, along with the health concerns of the athlete, e.g. unwanted effects from the FES and bladder infection, required creativity to ensure an effective and safe training protocol. The individual needs of the athlete and task requirements for the FES bike race made the design of a suitable training programme challenging, emphasizing the importance of monitoring. Several objective and subjective measures to assess the athlete's health and progress are presented, all with their own advantages and disadvantages. Despite these limitations, the athlete achieved a gold medal in the FES bike race Cybathlon Global Edition 2020 through discipline, team collaboration and the athlete's own motivation.

Abstract
Objective The objective of this scoping review was to identify the modifiable factors that impact the health and quality of life (QOL) of community-dwelling people with spinal cord injury (SCI). Methods Empirical journal articles were identified using three academic databases: CINAHL Complete, MEDLINE with Full Text, and PsycINFO. Full-text journal articlesincluded studies of participants who were community-dwelling with traumatic or nontraumatic SCI and were over the age of 18 years without cognitive impairment; published between 2000 and 2021; focused on modifiable factors impacting health and QOL; and conducted inAustralia, Europe, orNorth America. A data table was used to extract article information including authors, year of publication, country, sample, design and methods, purpose/objectives, and main findings. Qualitative data analysis software was used to categorize major findings inductively through content analysis. Results Thirty-one peer-reviewed articles consisting of qualitive, quantitative, and mixed-methods study design were included. This scoping review revealed modifiable factors that impact the health and QOL of community-dwelling people with SCI: sociostructural factors (social attitudes, health care access, information access, and funding and policies) and environmental factors (built environment, housing, transportation, assistive technology, and natural environment). Conclusion Future research should examine the influence of the modifiable factors on health and QOL using qualitative inquiry, adopting a community-based participatory research approach, and considering the implications of individual characteristics and resources.

Abstract
Spinal cord injury (SCI) is a complex neurophysiological disorder, which can result in many long-term complications including changes in mobility, bowel and bladder function, cardiovascular function, and metabolism. In addition, most individuals with SCI experience some form of chronic pain, with one-third of these individuals rating their pain as severe and unrelenting. SCI-induced chronic pain is considered to be "high impact" and broadly affects a number of outcome measures, including daily activity, physical and cognitive function, mood, sleep, and overall quality of life. The majority of SCI pain patients suffer from pain that emanates from regions located below the level of injury. This pain is often rated as the most severe and the underlying mechanisms involve injury-induced plasticity along the entire neuraxis and within the peripheral nervous system. Unfortunately, current therapies for SCI-induced chronic pain lack universal efficacy. Pharmacological treatments, such as opioids, anticonvulsants, and antidepressants, have been shown to have limited success in promoting pain relief. In addition, these treatments are accompanied by many adverse events and safety issues that compound existing functional deficits in the spinally injured, such as gastrointestinal motility and respiration. Non-pharmacological treatments are safer alternatives that can be specifically tailored to the individual and used in tandem with pharmacological therapies if needed. This review describes existing non-pharmacological therapies that have been used to treat SCI-induced pain in both preclinical models and clinical populations. These include physical (i.e., exercise, acupuncture, and hyper- or hypothermia treatments), psychological (i.e., meditation and cognitive behavioral therapy), and dietary interventions (i.e., ketogenic and anti-inflammatory diet). Findings on the effectiveness of these interventions in reducing SCI-induced pain and improving quality of life are discussed. Overall, although studies suggest non-pharmacological treatments could be beneficial in reducing SCI-induced chronic pain, further research is needed. Additionally, because chronic pain, including SCI pain, is complex and has both emotional and physiological components, treatment should be multidisciplinary in nature and ideally tailored specifically to the patient.

Abstract
Electromagnetic fields are emerging as a therapeutic option for patients with spasticity. They have been applied at brain or peripheral level. The effects of electromagnetic fields applied to the brain have been extensively studied for years in spasticity, but not so at the peripheral level. Therefore, the purpose of our work is to analyze the effects of electromagnetic fields, applied peripherally to spasticity. A systematic review was conducted resulting in 10 clinical trials. The frequency ranged from 1 Hz to 150 Hz, with 25 Hz being the most commonly used and the intensity it was gradually increased but there was low homogeneity in how it was increased. Positive results on spasticity were found in 80% of the studies: improvements in stretch reflex threshold, self questionnaire about difficulties related to spasticity, clinical spasticity score, performance scale, Ashworth scale, spastic tone, Hmax/Mmax Ratio and active and passive dorsal flexion. However, results must be taken with caution due to the large heterogeneity and the small number of articles. In future studies, it would be interesting to agree on the parameters to be used, as well as the way of assessing spasticity, to be more objective in the study of their effectiveness.

Abstract
INTRODUCTION Neuropathic pain after spinal cord injury is difficult to treat, and it is associated with abnormalities in the function of the thalamus-to-cortex neural circuitry. Aerobic exercise provides immediate improvement in neuropathic pain and is associated with abnormal resting electroencephalography (EEG) findings in patients with spinal cord injury. This study aimed to investigate whether physical therapy, including walking, can improve neuropathic pain and EEG peak alpha frequency (PAF) in the long term in a patient with cervical spinal cord injury. CASE PRESENTATION A 50-year-old man was admitted with a cervical spinal cord insufficiency injury sustained one week prior. The residual height was C5. Neuropathic pain was observed in the fingers bilaterally. A numerical rating scale (NRS) was evaluated to measure the weekly mean and maximum intensities of pain. Resting EEG was measured, and the PAF was calculated. Each time point was evaluated in 2-week intervals from the time of admission, and the rate of change (Δ) of PAF was calculated based on the initial evaluation. Interventions included 18 weeks of standard physical therapy focusing on gait, with additional intensive gait training (4-10 weeks). The NRS scores for the mean and maximum intensities of pain decreased significantly after 6 weeks, and ΔPAF increased significantly after 4 weeks. Improvement in PAF coincided with the start of intensive gait training. DISCUSSION PAF shifts to a high frequency during intensive gait training, suggesting the effectiveness of aerobic exercise. Furthermore, there is a close relationship between PAF, pain, and the quantification of pain changes.

Abstract
BACKGROUND Spinal cord injury (SCI) is associated with substantial chronic morbidity and mortality. Routine imaging techniques such as T1- and T2-weighted magnetic resonance imaging (MRI) are not effective in predicting neurological deficiency grade or outcome. Diffusional kurtosis imaging (DKI) is an MR imaging technique that provides microstructural information about biological tissue. There are no longitudinal prospective studies assessing DKI metrics in acute traumatic SCI. Therefore, the purpose of this study was to establish a DKI protocol for acute SCI and correlate the DKI metrics to the functional neurological outcome of the patients. METHODS Eight consecutive SCI patients referred to our institution with cervical SCI were included in the study. An acute diagnostic MRI scan was supplemented with a novel fast, mean kurtosis DKI protocol, which describes the average deviation from Gaussian diffusional along nine different directions. Mean kurtosis values were measured at the injury site and normalized to the mean kurtosis values of a non-injured site. At discharge form specialized rehabilitation, patients were evaluated using the Spinal Cord Independence Measure-III (SCIM-III). The DKI metrics and SCIM-III were analysed using Spearman's rank correlation. RESULTS This pilot study found a significant correlation between decreasing mean kurtosis values at the injury site of the spinal cord and higher grade of disability measured by the SCIM-III (p = 0.002). CONCLUSION This pilot study found that DKI may be a valuable tool as a prognostic marker in the acute phase of SCI.

Abstract
Power wheelchairs provide people with mobility disabilities opportunities for independence in mobility and repositioning themselves. However, current power wheelchair power options covered by Medicare limit the person to a horizontal plane. In the home, access to the vertical plane is also required for mobility related activities of daily living. Power standing systems on power wheelchairs are one option for providing access to the vertical environment, although currently these systems are not covered by Medicare. Power standing systems also aid in medical management and in preventing common comorbidities associated with chronic neurological and congenital healthcare conditions. Therefore, a legal group led an interdisciplinary effort to change Medicare policy on power standing systems. A policy analysis using Bardach’s Eightfold policy framework was conducted to analyze a clinical groups’ action within this interdisciplinary team. The clinical team considered three viable options to address the problem and evaluated these options against five criteria. Ultimately, a national coverage determination reconsideration would provide a needed opportunity for the coverage of power standing systems. Suggested coverage criteria for power standing systems, based on existing literature and expert clinical experience, are proposed.

Abstract
PURPOSE To evaluate the causality between interventions on spinal cord perfusion pressure and neurological outcome in traumatic spinal cord injury. METHODS A systematic review was conducted in concordance with PRISMA guidelines. The literature was found in the EMBASE, PUBMED, SCOPUS, and WEB OF SCIENCE. Eligible studies included those that reported measurements and interventions on the spinal cord perfusion pressure in either animals or patients suffering from spinal cord injury. Only studies that reported a clinical or relevant clinical outcome measure (i.e., neurophysiology) were included. RESULTS The search yielded 795 unique records, and six studies were included after careful review. These studies suggested a positive correlation between spinal cord perfusion pressure and neurological outcome, but conclusions on causality could not be made. CONCLUSION In spite of growing indications that neurological outcomes are related to the spinal cord perfusion pressure in traumatic spinal cord injuries, a solid conclusion cannot be made due to the limited literature available. Additional well-designed studies are needed to address this issue.

Abstract
OBJECTIVE Spasticity is a frequent complication after spinal cord injury (SCI), but the existing therapies provide only limited relief and are associated with adverse reactions. Therefore, we aimed to develop a novel strategy to ameliorate the spasticity induced by SCI. METHODS This nonrandomized controlled study used a repeated measurement design. The study involved four monkeys, two of which served as controls and only underwent spinal cord hemisection surgery at the T8 spine level. The other two monkeys underwent transplantation of sural nerve segments into the injured sites and long-term infusion of acidic fibroblast growth factor (aFGF). All monkeys received postoperative exercise training and therapy. RESULTS The combined therapy substantially reduced the spasticity in leg muscle tone, patella tendon reflex, and fanning of toes. Although all monkeys showed spontaneous recovery of function over time, the recovery in the controls reached a plateau and started to decline after 11 weeks. CONCLUSIONS The combination of peripheral nerve grafting and aFGF infusion may serve as a complementary approach to reduce the signs of spasticity in patients with SCI.

Abstract
Spinal cord injury (SCI) substantially increases the risk of neurogenic obesity, diabetes, and metabolic syndrome. Much like in the general population, a discussion of these syndromes in SCI would be incomplete without acknowledging the association of SCI with sleep-disordered breathing (SDB). This article will outline the interplay between obesity and obstructive sleep apnea (OSA), discussing the pathophysiology of obesity in OSA both for the general population and SCI population. The role of insulin resistance in SDB and SCI will also be examined. The epidemiology and pathophysiology of OSA and central sleep apnea in SCI are discussed through an examination of current evidence, followed by a review of central sleep apnea in SCI. Principles of diagnosis and management of SDB will also be discussed. Because sleep deprivation in itself can be a risk factor for developing obesity, the significance of comorbid insomnia in SCI is explored. Ultimately, a thorough sleep history, testing, and treatment are key to improving the sleep of individuals with SCI and to potentially reducing the impact of neurogenic obesity and metabolic syndrome.

Abstract
STUDY DESIGN Online survey distributed to healthcare professionals (HCPs) involved in care of spinal cord injury (SCI) patients with neurogenic lower urinary tract dysfunction (NLUTD). OBJECTIVES Identify and bring awareness to the variation of neurogenic bladder management in around the world. SETTING International online questionnaire. METHODS A 32-question survey was drafted and circulated among a global network of SCI experts for review. The survey was disseminated to healthcare professionals involved in the care of NLUTD in SCI patients via social media, grassroots methods, and international societies. The survey was available for 6 weeks and respondents answered questions regarding SCI population demographics, access to care, common neurogenic bladder management, diagnostic and imaging methods, complications, and follow up. RESULTS A total of 296 healthcare professionals, 132 from North America, 87 from Europe, 27 from Asia, 24 from Australia, 14 from South America, and 6 from Africa, responded to the survey. Global concurrence was noted among management method for patients without adequate hand function, first-line treatment for neurogenic detrusor overactivity, and common complications. Continents highly differed in responses regarding management method for patients with adequate hand function, frequency of patients reusing catheters, timing of urodynamics, and duration of antibiotic therapy for urinary tract infections. CONCLUSIONS The results of this international survey demonstrate the variability and uniqueness in neurogenic bladder management in SCI patients around the world. Increased international discourse and education will improve global communication and transparency with the efforts of reducing discrepancies in care.

Abstract
Spinal cord injury (SCI) affects the gastrointestinal (GI) tract in several ways, most notably by causing impairment of colonic motility and sphincter dysfunction. Altered GI function in the setting of neurological injury-also known as "neurogenic bowel dysfunction" (NBD) -strongly impacts the quality of life (QOL) of individuals living with SCI. Characterizing the severity of NBD, its impact on an individual's QOL, and which interventions have been successful or ineffective is integral to the routine care of people living with SCI. Treatment of NBD is generally multimodal and includes attention to diet, pharmacologic and mechanical stimulation, and possibly surgery. This article discusses the pathophysiology of NBD and specific approaches to its management.

Abstract
Objective: Provide guidance for preventive health and health maintenance after spinal cord injury (SCI) for primary care providers (PCPs). Main message: Individuals with SCI may not receive the same preventive health care as the general population. Additionally, SCI-related secondary conditions may put their health at risk. SCI is considered a complex condition associated with many barriers to receiving quality primary care. Attention to routine preventive care and the unique health considerations of persons with SCI can improve health and quality of life and may prevent unnecessary health care utilization. Conclusion: PCPs are experts in preventive care and continuity of care, however individuals with SCI may not receive the same preventive care due to numerous barriers. This article serves as a quick reference for PCPs.

Effects of Lower Thoracic Spinal Cord Stimulation on Bowel Management in Individuals With Spinal Cord Injury. Arch Phys Med Rehabil 2020; 102:1155-1164. [PMID: 33161007 DOI: 10.1016/j.apmr.2020.09.394] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2020] [Revised: 08/26/2020] [Accepted: 09/22/2020] [Indexed: 11/22/2022]
Abstract
OBJECTIVE To systematically determine whether use of the spinal cord stimulation (SCS) system to restore cough may improve bowel management (BM) in individuals with spinal cord injury (SCI). DESIGN Experimental studies (clinical trial). SETTING Inpatient hospital setting for electrode insertion; outpatient setting for measurement of respiratory pressures; home setting for application of SCS. PARTICIPANTS Participants (N=5) with cervical SCI. INTERVENTION A fully implantable SCS cough system was surgically placed in each subject. SCS was applied at home, 2-3 times/d, on a chronic basis, every time bowel regimen was performed and as needed for secretion management. Stimulus parameters were set at values resulting in near maximum airway pressure generation, which was used as an index of expiratory muscle strength. Participants also used SCS during their bowel routine. MAIN OUTCOME MEASURES Airway pressure generation achieved with SCS. Weekly completion of Bowel Routine Log including BM time, mechanical measures, and medications used. RESULTS Mean pressure during spontaneous efforts was 30±8 cmH2O. After a period of reconditioning, SCS resulted in pressure of 146±21 cmH2O. The time required for BM routines was reduced from 118±34 minutes to 18±2 minutes (P<.05) and was directly related to the magnitude of pressure development during SCS. Mechanical methods for BM were completely eliminated in 4 patients. No patients experienced fecal incontinence as result of SCS. Each participant also reported marked overall improvement associated with BM. CONCLUSIONS Our results of this pilot study suggest that SCS to restore cough may be a useful method to improve BM and life quality for both patients with SCI and their caregivers. Our results indicate that the improvement in BM is secondary to restoration of intra-abdominal pressure development.

Abstract
Context: Patient-reported outcome measures (PROMs) are valuable for capturing the impact of spasticity on health-related quality of life (HRQoL) in persons with spinal cord damage (SCD) and evaluating the efficacy of interventions. Objective: To provide practical guidance for measuring HRQoL in persons with spasticity following SCD. Methods: Literature reviews identified measures of HRQoL and caregiver burden, utilized in studies addressing spasticity in SCD. Identified measures were evaluated for clinical relevance and practicality for use in clinical practice and research. The PRISM, SCI-SET, EQ-5D and SF-36 instruments were mapped to the International Classification of Functioning, Disability and Health (ICF). The PRISM and SCI-SET were evaluated using the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) checklist. Results: Two spasticity-specific, five generic, and four preference-based measures were identified. ICF mapping and the COSMIN checklist supported the use of the PRISM and SCI-SET in SCD. The SF-36 is considered the most useful generic measure; disability-adapted versions may be more acceptable but further studies on psychometric properties are required. The SF-36 can be converted to a preference-based measure (SF-6D), or alternatively the EQ-5D can be used. While no measures specific to caregivers of people with SCD were identified, the Caregiver Burden Scale and the Zarit Burden Interview are considered suitable. Conclusion: Recommended measures include the PRISM and SCI-SET (condition-specific), SF-36 (generic), and Caregiver Burden Scale and Zarit Burden Interview (caregiver burden). Consideration should be given to using condition-specific and generic measures in combination; the PRISM or SCI-SET combined with SF-36 is recommended.

Abstract
BACKGROUND Spinal cord injury (SCI) has a significant impact on the quality of life (QoL) of affected patients. The aim of this review was to determine whether colostomy formation improves QoL in patients with SCI. METHODS The Cochrane Register, MEDLINE, Embase and CINAHL were searched using medical subject headings. The search was extended to the reference lists of identified studies, ClinicalTrials.gov and the WHO International Clinical Trials Registry. All clinical trials that included spinal injury and QoL, time spent on bowel care, and patient satisfaction with stoma were assessed. RESULTS A total of 15 studies were found (including 488 patients with a stoma), of which 13 were retrospective cross-sectional studies and two were case-control studies, one of which was prospective research. Nine of 11 studies focusing on QoL reported that patients' QoL was improved by the stoma, whereas the remaining two studies found no difference. Time spent on bowel care was significantly reduced in all 13 studies that considered this outcome, with patients reducing the average time spent on bowel care from more than 1 h to less than 15 min per day. All 12 studies assessing patient satisfaction with their stoma reported high patient satisfaction. CONCLUSION Stoma formation improves QoL, reduces time spent on bowel care, and increases independence. Stoma is an option that could be discussed and offered to patients with spinal cord injury.

Abstract
Background Evidence has suggested that human adipose-derived stem cells (hADSCs) and low-level laser has neuroprotective effects on spinal cord injury (SCI). Therefore, the combined effect of the hADSCs and laser on neuregeneration and neuropathic pain after SCI was investigated. Methods Forty-eight adult male Wistar rats with 200–250 g weight were used. Thirty minutes after compression, injury with laser was irritated, and 1 week following SCI, about 1 × 106 cells were transplanted into the spinal cord. Motor function and neuropathic pain were assessed weekly. Molecular and histological studies were done at the end of the fourth week. Results The combined application of hADSCs and laser has significantly improved motor function recovery (p = 0.0001), hyperalgesia (p < 0.05), and allodynia (p < 0.05). GDNF mRNA expression was significantly increased in hADSCs and laser+hADSC-treated animals (p < 0.001). Finally, co-administration of hADSCs and laser has enhanced the number of axons around cavity more than other treatments (p < 0.001). Conclusions The results showed that the combination of laser and ADSCs could significantly improve the motor function and alleviate SCI-induced allodynia and hyperalgesia. Therefore, using a combination of laser and hADSCs in future experimental and translational clinical studies is suggested.

Abstract
CONTEXT/OBJECTIVE For persons with spinal cord injury, spasticity commonly interferes with activities of daily living such as transfers. Electromyography can be used to objectively measure muscle spasms during transfers, but how electromyographic measures relate to the impact spasticity has on life, or to clinically-rated spasticity, is unclear. We aimed to characterize relationships among spasm duration and magnitude, impact of spasticity on daily life, and a clinical measure of extensor spasticity, as well as to determine reliability of the electromyographic measures. DESIGN Participants (N=19) underwent electromyographic measurements of involuntary muscle activity (spasm duration and magnitude) evoked in quadriceps muscles during transfers on two days. Impact of spasticity on daily life was measured with the Spinal Cord Injury Spasticity Evaluation Tool. Clinically-rated spasticity severity was measured with the Spinal Cord Assessment Tool for Spastic reflexes. RESULTS No significant associations were found between impact of spasticity and spasm duration, spasm magnitude, or clinical extensor spasticity score. Absolute and normalized spasm duration were positively associated with clinical extensor spasticity score (rho=0.510-0.667, P < 0.05). Spasm measures during transfers had good to excellent day-to-day reliability (rho=0.656-0.846, P < 0.05). CONCLUSIONS Electromyographic and clinical measures of involuntary activity in the lower extremity do not significantly relate to perceived impact of spasticity on daily life. However, quadriceps spasm duration during transfers is related to clinically-rated extensor spasticity. Electromyography is a reliable method of quantifying quadriceps spasms during transfers. Future investigations should identify factors that influence the impact of spasticity on life, which may help direct treatment strategies to reduce problematic impact.

Abstract
OBJECTIVES A clinical protocol was developed for clinicians to routinely assess and initiate treatment for patients with neuropathic pain (NP) in an acute care setting. The objectives of this study were to: (1) determine the incidence and onset of NP in patients with traumatic spinal cord injury during acute care and (2) describe how the implementation of a clinical protocol impacts the assessment and diagnosis of NP. MATERIALS AND METHODS The study was a cohort analysis with a pre-post-test utilizing a historical control. Data were retrospectively collected from a patient registry and charts. Participants were randomly selected in cohort 1 (control) and cohort 2 (NP clinical protocol). RESULTS The incidence of NP was 56% without significant difference between the cohorts (P=0.3). Onset of NP was 8 days (SD=14) across the study and >85% of the participants with NP were diagnosed within 2 weeks. Participants with incomplete injuries had a significant earlier onset than participants with complete injuries (6.2±12.8, 10.9±15.8 d; P=0.003). The mean number of days from hospital admission to initial assessment decreased with use of the NP clinical protocol (3.7±5.7 d; P=0.02). DISCUSSION This study demonstrates a high incidence and early onset of NP in traumatic spinal cord injury during acute hospital care, with an earlier emergence in participants with incomplete injury. The NP clinical protocol ensured continuous assessment and documentation of NP while decreasing the time to an initial screen, but did not impact diagnosis.

Abstract
RATIONALE Highly prevalent and severe sleep-disordered breathing caused by acute cervical spinal cord injury (quadriplegia) is associated with neurocognitive dysfunction and sleepiness and is likely to impair rehabilitation. OBJECTIVE To determine whether 3 months of autotitrating CPAP would improve neurocognitive function, sleepiness, quality of life, anxiety and depression more than usual care in acute quadriplegia. METHODS AND MEASUREMENTS Multinational, randomised controlled trial (11 centres) from July 2009 to October 2015. The primary outcome was neurocognitive (attention and information processing as measure with the Paced Auditory Serial Addition Task). Daytime sleepiness (Karolinska Sleepiness Scale) was a priori identified as the most important secondary outcome. MAIN RESULTS 1810 incident cases were screened. 332 underwent full, portable polysomnography, 273 of whom had an apnoea hypopnoea index greater than 10. 160 tolerated at least 4 hours of CPAP during a 3-day run-in and were randomised. 149 participants (134 men, age 46±34 years, 81±57 days postinjury) completed the trial. CPAP use averaged 2.9±2.3 hours per night with 21% fully 'adherent' (at least 4 hours use on 5 days per week). Intention-to-treat analyses revealed no significant differences between groups in the Paced Auditory Serial Addition Task (mean improvement of 2.28, 95% CI -7.09 to 11.6; p=0.63). Controlling for premorbid intelligence, age and obstructive sleep apnoea severity (group effect -1.15, 95% CI -10 to 7.7) did not alter this finding. Sleepiness was significantly improved by CPAP on intention-to-treat analysis (mean difference -1.26, 95% CI -2.2 to -0.32; p=0.01). CONCLUSION CPAP did not improve Paced Auditory Serial Addition Task scores but significantly reduced sleepiness after acute quadriplegia. TRIAL REGISTRATION NUMBER ACTRN12605000799651.

Abstract
A randomized controlled and blinded animal trial was conducted in the axolotl (Ambystoma mexicanum), which has the ability to regenerate from transectional spinal cord injury (SCI). The objective of the present study was to investigate the axolotl's ability to regenerate from a blunt spinal cord trauma in a clinical setting. Axolotls were block-randomized to the intervention (n=6) or sham group (n=6). A laminectomy of two vertebrae at the level caudal to the hind limbs was performed. To induce a blunt SCI, a 25 g rod was released on the exposed spinal cord. Multiple modalities were applied at baseline (pre-surgery), and subsequently every third week for a total of 9 weeks. Gradient echo magnetic resonance imaging (MRI) was applied to assess anatomical regeneration. To support this non-invasive modality, regeneration was assessed by histology, and functional regeneration was investigated using swimming tests and functional neurological examinations. MRI suggested regeneration within 6 to 9 weeks. Histological analysis at 9 weeks confirmed regeneration; however, this regeneration was not complete. By the experimental end, all animals exhibited restored full neurological function. The present study demonstrated that the axolotl is capable of regenerating a contusion SCI; however, the duration of complete regeneration required further investigation.

Abstract
Sleep disorders are commonly encountered in people living with spinal cord injury (SCI). Primary sleep disorders such as sleep-disordered breathing (SDB), sleep-related movement disorders, circadian rhythm sleep-wake disorders, and insomnia disorder are common conditions after SCI but remain under-recognized, underdiagnosed and therefore remain untreated for a majority of patients. Sleep disturbances in people living with SCI are associated with significant impairments of daytime function and quality of life. Previous reviews have described findings related mainly to SDB but have not examined the relationship between other sleep disorders and SCI. This narrative review examines various sleep abnormalities and related functional and physical impairments in people living with SCI. It discusses new evidence pertaining to management, highlights existing limitations in the literature and recommends future directions for research.

[PMID: 29142293 DOI: 10.1038/s41393-017-0026-2] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2017] [Revised: 10/02/2017] [Accepted: 10/03/2017] [Indexed: 02/08/2023]
Abstract
STUDY DESIGN Narrative review. OBJECTIVES The purpose is to review the organisation of the nerve pathways that control defecation and to relate this knowledge to the deficits in colorectal function after SCI. METHODS A literature review was conducted to identify salient features of defecation control pathways and the functional consequences of damage to these pathways in SCI. RESULTS The control pathways for defecation have separate pontine centres under cortical control that influence defecation. The pontine centres connect, separately, with autonomic preganglionic neurons of the spinal defecation centres and somatic motor neurons of Onuf's nucleus in the sacral spinal cord. Organised propulsive motor patterns can be generated by stimulation of the spinal defecation centres. Activation of the somatic neurons contracts the external sphincter. The analysis aids in interpreting the consequences of SCI and predicts therapeutic strategies. CONCLUSIONS Analysis of the bowel control circuits identifies sites at which bowel function may be modulated after SCI. Colokinetic drugs that elicit propulsive contractions of the colorectum may provide valuable augmentation of non-pharmacological bowel management procedures.

Abstract
Sleep problems are frequently addressed as a primary or secondary concern during the visit to the pediatric neurology clinic. Sleep disorders can mimic other neurologic diseases (e.g., epilepsy and movement disorders), and this adds challenges to the diagnostic process. Sleep disorders can significantly affect the quality of life and functionality of children in general and those with comorbid neurological diseases in particular. Understanding the pathophysiology of sleep disorders, recognizing the implications of sleep disorder in children with neurologic diseases and behavioral difficulties, and early intervention continue to evolve resulting in better neurocognitive outcomes.

Differences in health, participation and life satisfaction outcomes in adults following paediatric- versus adult-sustained spinal cord injury. Spinal Cord 2016; 54:1197-1202. [PMID: 27645265 DOI: 10.1038/sc.2016.45] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2016] [Revised: 02/24/2016] [Accepted: 03/03/2016] [Indexed: 12/29/2022]
Abstract
STUDY DESIGN Cross-sectional. OBJECTIVES To compare differences in self-reported health status, participation and life satisfaction outcomes between adults with a spinal cord injury (SCI) sustained during paediatric (P) versus adulthood (A) years. SETTING Ontario, Canada. METHODS Secondary analysis of data from the Study of Health and Activity in People with SCI. Eighty-seven participants who sustained an SCI prior to age 19 (M±s.e.=25±1.5 years postinjury (YPI)) were matched for lesion level (C2-L5), severity (complete/incomplete), gender, age, education and ethnicity with 87 participants who sustained an SCI at ⩾age 19 years (MYPI=12.8±1.1). RESULTS Those with a paediatric SCI reported significantly less pain, fewer visits to the physician in the past year, greater functional independence, social participation, occupational participation and minutes per day of moderate-to-vigorous physical activity than those who sustained an SCI in adulthood. No significant differences were found for the measures of depression, perceived health status or life satisfaction (P>0.05). With the exception of moderate-to-vigorous physical activity and visits to the physician in the past year, between-group differences were independent of YPI. CONCLUSIONS Regardless of time since injury, people who sustained a paediatric SCI reported better health and greater participation than those injured in adulthood. Nevertheless, both groups scored well below able-bodied normative values for all measures. The results highlight the importance of a comprehensive life-course approach to SCI rehabilitation, irrespective of age at the time of injury.

Abstract
OBJECTIVE To describe the surgical management and long-term outcome of a spinal gunshot injury in a cat. CLINICAL REPORT A two-year-old, 4.2 kg castrated European Shorthair male cat was referred for evaluation of bilateral acute hindlimb paralysis with loss of deep pain perception in the right hindlimb associated with a perforating gunshot wound in the left side of the flank. Based on the clinical findings, the injury was localized to the fourth lumbar-first sacral spinal cord segment. The orthogonal spinal radiographs and computed tomography examination showed several metal pellet fragments within the vertebral canal of the sixth lumbar vertebra. A left mini-hemilaminectomy of the sixth lumbar vertebra pedicle combined with a mini dorsal laminectomy over the sixth to seventh lumbar vertebrae disc space were performed. A 2.4 mm 30° arthroscope was then introduced within the spinal canal to improve visibility and help with the fragment extraction. The cat was discharged from the hospital five days after surgery and the owners were encouraged to continue passive and active physiotherapy movements. RESULTS The cat was ambulatory with a plantigrade stance eight weeks following surgery. At the last follow-up examination (24 months postoperatively), the cat was able to jump on chairs, although intermittent urinary and faecal incontinence, proprioceptive deficits, and plantigrade stance were still present. CLINICAL SIGNIFICANCE Decompressive surgery may promote neurological status improvement following spinal gunshot injury.

Abstract
OBJECTIVE
Spinal cord injury occurs in 2 phases. The initial trauma is followed by inflammation that leads to fibrous scar tissue, glial scarring, and cavity formation. Scarring causes further axon death around and above the injury. A reduction in secondary injury could lead to functional improvement. In this study, hyaluronic acid (HA) hydrogels were implanted into the gap formed in the hemisected spinal cord of Sprague-Dawley rats in an attempt to attenuate damage and regenerate tissue.
METHODS
A T-10 hemisection spinal cord injury was created in adult male Sprague-Dawley rats; the rats were assigned to a sham, control (phosphate-buffered saline), or HA hydrogel–treated group. One cohort of 23 animals was followed for 12 weeks and underwent weekly behavioral assessments. At 12 weeks, retrograde tracing was performed by injecting Fluoro-Gold in the left L-2 gray matter. At 14 weeks, the animals were killed. The volume of the lesion and the number of cells labeled from retrograde tracing were calculated. Animals in a separate cohort were killed at 8 or 16 weeks and perfused for immunohistochemical analysis and transmission electron microscopy. Samples were stained using H & E, neurofilament stain (neurons and axons), silver stain (disrupted axons), glial fibrillary acidic protein stain (astrocytes), and Iba1 stain (mononuclear cells).
RESULTS
The lesions were significantly smaller in size and there were more retrograde-labeled cells in the red nuclei of the HA hydrogel–treated rats than in those of the controls; however, the behavioral assessments revealed no differences between the groups. The immunohistochemical analyses revealed decreased fibrous scarring and increased retention of organized intact axonal tissue in the HA hydrogel–treated group. There was a decreased presence of inflammatory cells in the HA hydrogel–treated group. No axonal or neuronal regeneration was observed.
CONCLUSIONS
The results of these experiments show that HA hydrogel had a neuroprotective effect on the spinal cord by decreasing the magnitude of secondary injury after a lacerating spinal cord injury. Although regeneration and behavioral improvement were not observed, the reduction in disorganized scar tissue and the retention of neurons near and above the lesion are important for future regenerative efforts. In addition, this gel would be useful as the base substrate in the development of a more complex scaffold.

Abstract
Objective: To identify nursing problems of spinal cord injured (SCI) patients after discharge from clinical rehabilitation and to identify gaps in the nursing care regarding the prevention of these problems. Design: The study had an exploratory character and was divided into three phases. Phase 1 had a qualitative nature. Eight patients were interviewed to obtain insight into experienced problems after discharge. In phase 2, a panel of experts regarding nursing care for SCI patients selected nursing problems out of all problems mentioned. Phase 3 consisted of a mailed questionnaire including the nursing problem areas identified in phase 2, which was sent to all patients that were discharged during the last 18 months before the study. Setting: Specialist rehabilitation centre, the Netherlands. Subjects: Eight patients participated in phase 1 (100% response rate), 35 nurses participated in phase 2 (87.5% response rate) and 35 patients participated in phase 3 (62.5% response rate). Results: The most important nursing problems in the response group appeared to be: limitations to activities of daily living, having difficulties in asking for help (assertiveness), pain, coping with the disability, dependency on personal help and problems with changed bladder regulation. The respondents made several suggestions for improving nursing care, involving both clinical care and care after discharge. Conclusions: SCI patients experience serious problems after discharge from clinical rehabilitation. Nurses can give input on a wide variety of these problems.

Optimizing the Management of Disabling Spasticity Following Spinal Cord Damage: The Ability Network-An International Initiative. Arch Phys Med Rehabil 2016; 97:2222-2228.

Abstract
Optimizing the treatment of disabling spasticity in persons with spinal cord damage is hampered by a lack of consensus regarding the use of acceptable definitions of spasticity and disabling spasticity, and the relative absence of decision tools such as clinical guidelines and concise algorithms to support decision-making within the broader clinical community. Many people with spinal cord damage are managed outside specialist centers, and variations in practice result in unequal access to best practice despite equal need. In order to address these issues, the Ability Network-an international panel of clinical experts-was initiated to develop management algorithms to guide and standardize the assessment, treatment, and evaluation of outcomes of persons with spinal cord damage and disabling spasticity. To achieve this, consensus was sought on common definitions through facilitated, in-person meetings. To guide patient selection, an in-depth review of the available tools was performed and expert consensus sought to develop an appropriate instrument. Literature reviews are guiding the selection and development of tools to evaluate treatment outcomes (body functions, activity, participation, quality of life) as perceived by people with spinal cord damage and disabling spasticity, and their caregivers and clinicians. Using this approach, the Ability Network aims to facilitate treatment decisions that take into account the following: the impact of disabling spasticity on health status, patient preferences, treatment goals, tolerance for adverse events, and in cases of totally dependent persons, caregiver burden.

Abstract
OBJECTIVE The aim of this study was to determine the efficacy of measuring the diameter and area of the rectum using ultrasonography as an additional parameter for the evaluation of neurogenic bowel in patients with spinal cord injury (SCI). PARTICIPANTS In total, 32 patients with SCI (16 patients with upper motor neuron neurogenic bowel (UMNB) and 16 patients with lower motor neuron neurogenic bowel (LMNB)) participated in this study. We divided the patients by the type of neurogenic bowel: UMNB, patients with supraconal lesions and recovery state of spinal shock or LMNB, patients with infraconal/caudal lesions or spinal shock state). INTERVENTION Ultrasound was applied on the abdomen and measured the diameter and area of the rectum were measured twice each before and after defecation, respectively. OUTCOME MEASURE We compared rectal diameter and area before/after defecation between the two groups, and significant differences were found in both rectal diameter and area before/after defecation in each group. RESULTS After defecation, those in the UMNB group had smaller rectal diameters and areas than those in the LMNB group. Significant reduction of rectal diameter and area was observed after defecation as well. The LMNB group showed slightly increased rectal area after defecation, but the increase was not statistically significant. CONCLUSION Using ultrasound to measure rectal diameter and area seems helpful for classifying neurogenic bowel types and for understanding the neurogenic bowel among SCI patients with symptoms of neurogenic bowel.

Abstract
Chronic pain is common in patients with neurologic complications of a central nervous system insult such as stroke. The pain is most commonly musculoskeletal or related to obligatory overuse of neurologically unaffected limbs. However, neuropathic pain can result directly from the central nervous system injury. Impaired sensory discrimination can make it challenging to differentiate central neuropathic pain from other pain types or spasticity. Central neuropathic pain may also begin months to years after the injury, further obscuring recognition of its association with a past neurologic injury. This review focuses on unique clinical features that help distinguish central neuropathic pain. The most common clinical central pain syndromes-central poststroke pain, multiple sclerosis-related pain, and spinal cord injury-related pain-are reviewed in detail. Recent progress in understanding of the pathogenesis of central neuropathic pain is reviewed, and pharmacological, surgical, and neuromodulatory treatments of this notoriously difficult to treat pain syndrome are discussed.

Abstract
OBJECTIVE To describe expected imaging findings to assist the emergency room radiologist with recognising complications and pathology unique to the spinal cord injury (SCI) patient population to ensure rapid and accurate diagnosis. METHODS Pictorial review. RESULTS We review several imaging findings common to persons with chronic SCI, emphasising imaging in the emergency setting and on CT. CONCLUSION SCI patients present a unique diagnostic challenge, as they may present with symptoms that are difficult to localise because of abnormal sensation and autonomic instability. Imaging plays an important role in the emergent setting, rapidly differentiating the most commonly encountered complications from less common, unanticipated complications. Radiologists need to be attuned to both the expected findings and potential complications, which may be unique to SCI patients, to ensure accurate diagnosis and treatment in the emergency setting. MAIN MESSAGES • Medical complications after spinal cord injury are common and associated with significant morbidity. • Radiologists should be aware of complications unique to the SCI population to aid diagnosis. • Due to abnormal sensation, SCI patients often present with symptoms that are difficult to localise. • In the ED, imaging helps to rapidly differentiate common complications from less anticipated ones.

Abstract
OBJECTIVE To describe bowel management and its outcomes in individuals living with a spinal cord injury (SCI) for at least 10 years. DESIGN Cross-sectional multicenter study. SETTING Dutch community. PARTICIPANTS Individuals (N=258; age range, 28-65y) who acquired their SCI between 18 and 35 years of age, who were at least 10 years post-SCI, and who used a wheelchair for their daily mobility. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES The International SCI Bowel Function Basic Data Set, the neurogenic bowel dysfunction (NBD) score, and a single item on satisfaction with bowel management. RESULTS Mean time since injury (TSI) was 24±9 years. Seventy-four percent used ≥1 conservative bowel management method, specifically digital evacuation (35%) and mini enemas (31%). Transanal irrigation (TAI) and surgical interventions were used by 11% and 8%, respectively. Perianal problems were reported by 45% of the participants. Severe NBD was present in 36% of all participants and in 40% of those using a conservative method. However, only 14% were (very) dissatisfied with their current bowel management. Dissatisfaction with bowel management was significantly associated with constipation and severe NBD. With increasing TSI, there was a nonsignificant trend observed toward a decline in dissatisfaction with bowel management and a significant decline in severe NBD. CONCLUSIONS Although satisfaction rates were high, more than a third of the participants reported severe NBD and perianal problems. Apart from severe NBD, there were no significant associations between bowel problems and TSI. Conservative methods were most often used, but some of these methods were also significantly associated with the presence of severe NBD. Longitudinal research is necessary to provide more knowledge concerning the course of NBD with increasing TSI.

Abstract
Non-invasive brain stimulations mainly consist of repetitive transcranial magnetic stimulation and transcranial direct current stimulation. Repetitive transcranial magnetic stimulation exhibits satisfactory outcomes in improving multiple sclerosis, stroke, spinal cord injury and cerebral palsy-induced spasticity. By contrast, transcranial direct current stimulation has only been studied in post-stroke spasticity. To better validate the efficacy of non-invasive brain stimulations in improving the spasticity post-stroke, more prospective cohort studies involving large sample sizes are needed.

Abstract
Sleep-disordered breathing has been shown to be more prevalent in patients with spinal cord injury (SCI) than the general population. The pathogenesis of increased sleep-disordered breathing in individuals with chronic SCI is unknown. The purpose of this study is to determine whether SCI level affects upper airway (UA) collapsibility and neuromuscular compensatory responses to obstruction. Twenty-four participants (8 cervical SCI, 8 thoracic SCI, and 8 controls) were studied. The ventilation, timing, UA resistance, and pharyngeal collapsibility, defined by critical closing pressure, were determined during non-rapid eye movement sleep. Inspiratory duty cycle and minute ventilation were observed in response to increasing severity of UA obstruction. Compared with controls, both cervical and thoracic SCI participants demonstrated elevated passive critical closing pressure (0.5 ± 2.2 and 0.9 ± 2.7 vs. −2.5 ± 1.0 cmH2O, respectively; P = 0.01). No difference in UA resistance was observed between groups. Cervical and thoracic SCI individuals exhibited a similar degree of hypoventilation and dose-dependent increase in inspiratory duty cycle in response to UA obstruction. Passive UA collapsibility is increased in both cervical and thoracic SCI compared with control. The neuromuscular compensatory responses to UA obstruction during sleep are preserved in chronic SCI and are independent of the level of injury.

Abstract
OBJECTIVES To determine longitudinal changes in the occurrence of medical complications in adults with pediatric-onset spinal cord injury (SCI). DESIGN Longitudinal study of long-term outcomes. SETTING Community. PARTICIPANTS Individuals who had sustained an SCI before age 19, were 23 years of age or older at initial interview, and followed annually between 1996 and 2011. They were classified into four American Spinal Injury Association (ASIA) Impairment Scale (AIS) severity groups: C1-4 AIS ABC, C5-8 AIS ABC, T1-S5 AIS ABC, AIS D. OUTCOME MEASURES Generalized estimating equation (GEE) models were formulated to obtain the odds ratio (OR) of having a medical complication over time. RESULTS A total of 1793 interviews were conducted among 226 men and 125 women (86% Caucasian; age at baseline, 26.7 ± 3.6 years; time since injury at baseline, 12.9 ± 5.2 years). Odds of complication occurrence over time varied among severity groups, with increased ORs of severe urinary tract infection (1.05, confidence interval (CI) 1.02-1.09), autonomic dysreflexia (AD) (1.09, CI 1.05-1.14), spasticity (1.06, CI 1.01-1.11), pneumonia/respiratory failure (1.09, CI 1.03-1.16), and hypertension/cardiac disease (1.07, CI 1.01-1.15) in the C1-4 ABC group; AD (1.08, CI 1.04-1.13) and pneumonia/respiratory failure (1.09, CI 1.02-1.16) in the C5-8 ABC group; and hypertension/cardiac disease (1.08, CI 1.02-1.14) in the T1-S5 ABC group. Upper extremity joint pain had increased odds of occurrence in all injury severity groups. CONCLUSION The significantly increased odds of having medical complications over time warrants awareness of risk factors and implementation of preventive measures to avoid adverse consequences of complications and to maintain independence in individuals with pediatric-onset SCI.

Abstract
STUDY OBJECTIVES Spinal cord injury (SCI) is associated with 2-5 times greater prevalence of sleep disordered breathing (SDB) than the general population. The contribution of SCI on sleep and breathing at different levels of injury using two scoring methods has not been assessed. The objectives of this study were to characterize the sleep disturbances in the SCI population and the associated physiological abnormalities using quantitative polysomnography and to determine the contribution of SCI level on the SDB mechanism. METHODS We studied 26 consecutive patients with SCI (8 females; age 42.5 ± 15.5 years; BMI 25.9 ± 4.9 kg/m2; 15 cervical and 11 thoracic levels) by spirometry, a battery of questionnaires and by attended polysomnography with flow and pharyngeal pressure measurements. Inclusion criteria for SCI: chronic SCI (> 6 months post injury), level T6 and above and not on mechanical ventilation. Ventilation, end-tidal CO2 (PETCO2), variability in minute ventilation (VI-CV) and upper airway resistance (RUA) were monitored during wakefulness and NREM sleep in all subjects. Each subject completed brief history and exam, Epworth Sleepiness Scale (ESS), Pittsburgh Sleep Quality Index (PSQI), Berlin questionnaire (BQ) and fatigue severity scale (FSS). Sleep studies were scored twice, first using standard 2007 American Academy of Sleep Medicine (AASM) criteria and second using new 2012 recommended AASM criteria. RESULTS Mean PSQI was increased to 10.3 ± 3.7 in SCI patients and 92% had poor sleep quality. Mean ESS was increased 10.4 ± 4.4 in SCI patients and excessive daytime sleepiness (ESS ≥ 10) was present in 59% of the patients. Daytime fatigue (FSS > 20) was reported in 96% of SCI, while only 46% had high-risk score of SDB on BQ. Forced vital capacity (FVC) in SCI was reduced to 70.5% predicted in supine compared to 78.5% predicted in upright positions (p < 0.05). Likewise forced expiratory volume in first second (FEV1) was 64.9% predicted in supine compared to 74.7% predicted in upright positions (p < 0.05). Mean AHI in SCI patients was 29.3 ± 25.0 vs. 20.0 ± 22.8 events/h using the new and conventional AASM scoring criteria, respectively (p < 0.001). SCI patients had SDB (AHI > 5 events/h) in 77% of the cases using the new AASM scoring criteria compared to 65% using standard conventional criteria (p < 0.05). In cervical SCI, VI decreased from 7.2 ± 1.6 to 5.5 ± 1.3 L/min, whereas PETCO2 and VI-CV, increased during sleep compared to thoracic SCI. CONCLUSION The majority of SCI survivors have symptomatic SDB and poor sleep that may be missed if not carefully assessed. Decreased VI and increased PETCO2 during sleep in patients with cervical SCI relative to thoracic SCI suggests that sleep related hypoventilation may contribute to the pathogenesis SDB in patients with chronic cervical SCI.

Abstract
OBJECTIVE To determine the effectiveness of a melatonin agonist for treating sleep disturbances in individuals with tetraplegia. DESIGN Placebo-controlled, double-blind, crossover, randomized control trial. SETTING At home. PARTICIPANTS Eight individuals with tetraplegia, having an absence of endogenous melatonin production and the presence of a sleep disorder. Interventions Three weeks of 8 mg of ramelteon (melatonin agonist) and 3 weeks of placebo (crossover, randomized order) with 2 weeks of baseline prior to and 2 weeks of washout between active conditions. OUTCOME Change in objective and subjective sleep. MEASURES Wrist actigraphy, post-sleep questionnaire, Stanford sleepiness scale, SF-36. RESULTS We observed no consistent changes in either subjective or objective measures of sleep, including subjective sleep latency (P = 0.55, Friedman test), number of awakenings (P = 0.17, Friedman test), subjective total sleep time (P = 0.45, Friedman test), subjective morning alertness (P = 0.35, Friedman test), objective wake after sleep onset (P = 0.70, Friedman test), or objective sleep efficiency (P = 0.78, Friedman test). There were significant increases in both objective total sleep time (P < 0.05, Friedman test), subjective time in bed (P < 0.05, Friedman test), and subjective sleep quality (P < 0.05, Friedman test), although these occurred in both arms. There were no significant changes in any of the nine SF-36 subscale scores (Friedman test, Ps >Bonferroni adjusted α of 0.005). CONCLUSION In this pilot study, we were unable to show effectiveness of pharmacological replacement of melatonin for the treatment of self-reported sleep problems in individuals with tetraplegia.

Abstract
BACKGROUND To better understand service-related needs and the current situation of persons with spinal cord injury (SCI) living in the community, a more comprehensive approach for studying their interrelationships (needs vs community living outcomes) is greatly needed. OBJECTIVE To describe the development, design, and findings of a Canadian survey portraying the life situation of people with SCI. METHOD The SCI Community Survey covers demographics, health, SCI-specific needs, community participation, employment, quality of life, health care utilization, and overall health rating. A total of 1,549 persons with SCI completed the survey (Web or phone) between May 2011 and August 2012. RESULTS Some major expressed needs for services to support community living are met to a great extent for a substantial proportion of people with SCI. Complications remain highly prevalent for some health issues, including pain, sexual dysfunction, and musculoskeletal disorders. The extent of community participation based on values and preferences varies tremendously among daily activities and social roles. Some dimensions of quality of life are rated positively (eg, family life) while others are greatly disrupted (eg, sex life and physical health). Most of these findings vary significantly between people with traumatic and nontraumatic lesions. CONCLUSION This survey is the first in Canada and among the first worldwide to draw a comprehensive picture of major aspects of the lives of people with SCI including service needs. The results will help to determine the links between various aspects of community living and guide service providers and policy makers in focusing on major issues to enhance quality of life after SCI.
