Abstract
ABSTRACT Environmental scans determine trends in an organization's or field's internal and external environment. The results can help shape goals, inform strategic decision making, and direct future actions. The Association of Academic Physiatrists convened a strategic planning group in 2020, composed of physiatrists representing a diversity of professional roles, career stages, race and ethnicity, gender, disability status, and geographic areas of practice. This strategic planning group performed an environmental scan to assess the forces, trends, challenges, and opportunities affecting both the Association of Academic Physiatrists and the entire field of academic physiatry (also known as physical medicine and rehabilitation, physical and rehabilitation medicine, and rehabilitation medicine). This article presents aspects of the environmental scan thought to be most pertinent to the field of academic physiatry organized within the following five themes: (1) Macro/Societal Trends, (2) Technological Advancements, (3) Diversity and Global Outreach, (4) Economy, and (5) Education/Learning Environment. The challenges and opportunities presented here can provide a roadmap for the field to thrive within the complex and evolving healthcare systems in the United States and globally.

A review and evaluation of patient-reported outcome measures for spasticity in persons with spinal cord damage: Recommendations from the Ability Network - an international initiative. J Spinal Cord Med 2020; 43:813-823.

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
Context: Implementing research findings into clinical practice is challenging. This manuscript outlines the experiences and key learnings from a network that operated as a community of practice across seven Canadian Spinal Cord Injury (SCI) rehabilitation centers. These learnings are being used to inform a new implementation-focused network involving SCI rehabilitation programs based in Ontario, Canada. Methods: The SCI KMN adapted and applied implementation science principles based on the National Implementation Research Network's (NIRN) Active Implementation Frameworks in the implementation of best practices in pressure injury and pain prevention and management. Results: The SCI KMN was successful in implementing best practices in both pressure ulcer and pain prevention and management across the various participating sites. Other key objectives met were building capacity in implementation methods in site personnel so that project scaling could occur with these skills and expertise applied to numerous other initiatives. Additionally, various papers, abstracts and conference presentation as well as an implementation guide were disseminated to inform the field of implementation science. Conclusion: The key lessons learned from this experience are being used to develop a new implementation-focused network. Features felt to be especially important for the SCI KMN includes a highly representative governance structure, the use of indicators within an overall evaluation framework and the systematic application of implementation processes with shared learnings supporting each site.

The Spinal Cord Injury Pressure Ulcer Scale (SCIPUS): an assessment of validity using Rasch analysis. Spinal Cord 2019; 57:874-880. [PMID: 31053776 DOI: 10.1038/s41393-019-0287-z] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2018] [Revised: 04/23/2019] [Accepted: 04/24/2019] [Indexed: 11/09/2022]
Abstract
STUDY DESIGN Secondary analysis of retrospective data. OBJECTIVE The aim of this study was to further validate the Spinal Cord Injury Pressure Ulcer Scale (SCIPUS) using Rasch analysis. SETTING Two rehabilitation centers in Canada. METHOD Data were collected as part of the Spinal Cord Injury Knowledge Mobilization Network (SCI KMN) initiative. The SCIPUS was completed within 72 h of inpatient admission. Persons admitted for initial rehabilitation in two inpatient spinal cord rehabilitation programs were included in the project. RESULTS Data from 886 participants were analyzed, approximately 60% of whom were males. Rasch analyses demonstrated that the SCIPUS, in its current format did not meet criteria required for true measurement. A transformed version of the SCIPUS obtained by deletion of misfitting items and modification of the response scales improved fit to the model and showed preliminary evidence of unidimensionality. The person separation index, however indicated that the scale requires further adjustments of its scoring options. CONCLUSIONS In its original form, the SCIPUS does not meet the requirements of the Rasch model and its total score should be used cautiously. However, following some adjustments to the items such as addressing DIF between sites to insure a standardized assessment across sites and adding response options to some of the items, interval-scale measurement should be possible.

Determining Pressure Injury Risk on Admission to Inpatient Spinal Cord Injury Rehabilitation: A Comparison of the FIM, Spinal Cord Injury Pressure Ulcer Scale, and Braden Scale. Arch Phys Med Rehabil 2019; 100:1881-1887. [PMID: 31054293 DOI: 10.1016/j.apmr.2019.04.004] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2019] [Revised: 03/27/2019] [Accepted: 04/04/2019] [Indexed: 10/26/2022]
Abstract
OBJECTIVE Assess the utility of the admission Spinal Cord Injury Pressure Ulcer Scale (SCIPUS), Braden Scale, and the FIM for identifying individuals at risk for developing pressure injury during inpatient spinal cord injury (SCI) rehabilitation. DESIGN Retrospective cohort. SETTING Two tertiary rehabilitation centers. PARTICIPANTS Individuals (N=754) participating in inpatient SCI rehabilitation. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Logistic regression analysis was performed to determine the utility of the SCIPUS, Braden Scale, and FIM for identifying individuals at risk for developing pressure injury (PI) during inpatient SCI rehabilitation. Sensitivity, specificity, positive predictive value, negative predictive value, false negative rate, odds ratio, likelihood ratio, and area under the curve (AUC) are reported. RESULTS The SCIPUS total score and its individual items did not demonstrate acceptable accuracy (AUC≥0.7) whereas the Braden Scale (0.73) and the FIM score (0.74) did. Once items were dichotomized into high and low risk categories, 1 Braden item (friction and shear), 5 FIM items (bathing, toileting, bed/chair transfer, tub/shower transfer, toilet transfer), the FIM transfers subscale, FIM Motor subscale, and the FIM instrument as a whole, maintained AUCs ≥0.7 and negative predictive values ≥0.95. The FIM bed/chair transfer score demonstrated the highest likelihood ratio (2.62) and overall was the most promising measure for determining PI risk. CONCLUSION Study findings suggest that a simple measure of mobility, admission FIM bed/chair transfer score of 1 (total assist), can identify at-risk individuals with greater accuracy than both an SCI specific instrument (SCIPUS) and a PI specific instrument (Braden). The FIM bed/chair transfer score can be readily determined at rehabilitation admission with minimal administrative and clinical burden.

Abstract
Spinal cord injury (SCI) is a devastating event causing lifelong disability that results in a significant decrease in quality of life and immense cost to the health care system, individuals and their families. Providing specialized and timely care can improve recovery and reduce costs, but to make this a reality requires understanding of the current care delivery processes and the care journey. The objective of this focus issue is to examine the current state of health care delivery and discover opportunities to improve access and timing to specialized care for individuals with tSCI. This issue provides an overview of care throughout the SCI continuum and its impact on individuals with tSCI using pan-Canadian data. The issue also presents findings from the RHI Access to Care and Timing (ACT) Project, a multi-center research study involving a multi-disciplinary team of Canadian researchers and clinicians. The initial articles describe the current state of the tSCI care journey including a comparison of environmental barriers, health status, and quality-of-life outcomes between patients living in rural and urban settings. The issue concludes with an article describing the national knowledge translation efforts of using the evidence from the articles published here to inform practice and policy change. Overall, this focus issue will be an excellent reference to guide and optimize evidence informed decision-making in the care of those with tSCI. The evidence can be transferred to care in non-traumatic SCI and other conditions that benefit from timely access to specialized care such as stroke and traumatic brain injury.

Abstract
A thorough assessment of the extent and severity of spasticity, and its effect on functioning, is central to the effective management of spasticity in persons with spinal cord damage (SCD). These individuals however do not always receive adequate assessment of their spasticity. Inadequate assessment compromises management when the effect of spasticity and/or need for intervention are not fully recognized. Assessment is also central to determining treatment efficacy. A barrier to spasticity assessment has been the lack of consensus on clinical and functional measures suitable for routine clinical practice. To extend on existing work, a working group of the Ability Network identified and consolidated information on possible measures, and then synthesized and formulated findings into practical recommendations for assessing spasticity and its effect on function in persons with SCD. Sixteen clinical and functional measures that have been used for this purpose were identified using a targeted literature review. These were mapped to the relevant domains of the International Classification of Functioning, Disability and Health to assess the breadth of their coverage; coverage of many domains was found to be lacking, suggesting a focus for future work. The advantages, disadvantages, and usefulness of the measures were assessed using a range of criteria, with a focus on usefulness and feasibility in routine clinical practice. Based on this evaluation, a selection of measures suitable for initial and follow-up assessments are recommended. The recommendations are intended to have broad applicability to a variety of health care settings where people with SCD are managed.

Optimizing the Management of Spasticity in People With Spinal Cord Damage: A Clinical Care Pathway for Assessment and Treatment Decision Making From the Ability Network, an International Initiative. Arch Phys Med Rehabil 2018; 99:1681-1687.

Abstract
The recognition, evaluation, and management of disabling spasticity in persons with spinal cord damage (SCD) is a challenge for health care professionals, institutions, health systems, and patients. To guide the assessment and management of disabling spasticity in individuals with SCD, the Ability Network, an international panel of clinical experts, developed a clinical care pathway. The aim of this pathway is to facilitate treatment decisions that take into account the effect of disabling spasticity on health status, individual preferences and treatment goals, tolerance for adverse events, and burden on caregivers. The pathway emphasizes a patient-centered, individualized approach and the need for interdisciplinary coordination of care, patient involvement in goal setting, and the use of assessment and outcome measures that lend themselves to practical application in the clinic. The clinical care pathway is intended for use by health care professionals who provide care for persons with SCD and disabling spasticity in various settings. Barriers to optimal spasticity management in these people are also discussed. There is an urgent need for the clinical community to clarify and overcome barriers (knowledge-based, organizational, health system) to optimizing the management of spasticity in people with SCD.

Abstract
OBJECTIVE To develop recommendations on the timing of surgical decompression in patients with traumatic spinal cord injury (SCI) and central cord syndrome. METHODS A systematic review of the literature was conducted to address key relevant questions. A multidisciplinary guideline development group used this information, along with their clinical expertise, to develop recommendations for the timing of surgical decompression in patients with SCI and central cord syndrome. Based on GRADE, a strong recommendation is worded as "we recommend," whereas a weak recommendation is presented as "we suggest." RESULTS Conclusions from the systematic review included (1) isolated studies reported statistically significant and clinically important improvements following early decompression at 6 months and following discharge from inpatient rehabilitation; (2) in one study on acute central cord syndrome without instability, a marginally significant improvement in total motor scores was reported at 6 and 12 months in patients managed with early versus late surgery; and (3) there were no significant differences in length of acute care/rehabilitation stay or in rates of complications between treatment groups. Our recommendations were: "We suggest that early surgery be considered as a treatment option in adult patients with traumatic central cord syndrome" and "We suggest that early surgery be offered as an option for adult acute SCI patients regardless of level." Quality of evidence for both recommendations was considered low. CONCLUSIONS These guidelines should be implemented into clinical practice to improve outcomes in patients with acute SCI and central cord syndrome by promoting standardization of care, decreasing the heterogeneity of management strategies, and encouraging clinicians to make evidence-informed decisions.

Abstract
INTRODUCTION The objective of this study is to develop evidence-based guidelines that recommend effective, safe and cost-effective thromboprophylaxis strategies in patients with spinal cord injury (SCI). METHODS A systematic review of the literature was conducted to address key questions relating to thromboprophylaxis in SCI. Based on GRADE (Grading of Recommendation, Assessment, Development and Evaluation), a strong recommendation is worded as "we recommend," whereas a weaker recommendation is indicated by "we suggest." RESULTS Based on conclusions from the systematic review and expert panel opinion, the following recommendations were developed: (1) "We suggest that anticoagulant thromboprophylaxis be offered routinely to reduce the risk of thromboembolic events in the acute period after SCI;" (2) "We suggest that anticoagulant thromboprophylaxis, consisting of either subcutaneous low-molecular-weight heparin or fixed, low-dose unfractionated heparin (UFH) be offered to reduce the risk of thromboembolic events in the acute period after SCI. Given the potential for increased bleeding events with the use of adjusted-dose UFH, we suggest against this option;" (3) "We suggest commencing anticoagulant thromboprophylaxis within the first 72 hours after injury, if possible, in order to minimize the risk of venous thromboembolic complications during the period of acute hospitalization." CONCLUSIONS These guidelines should be implemented into clinical practice in patients with SCI to promote standardization of care, decrease heterogeneity of management strategies and encourage clinicians to make evidence-informed decisions.

INTRODUCTION The objective of this study is to develop guidelines that outline the appropriate type and timing of rehabilitation in patients with acute spinal cord injury (SCI). METHODS A systematic review of the literature was conducted to address key questions related to rehabilitation in patients with acute SCI. A multidisciplinary guideline development group used this information, and their clinical expertise, to develop recommendations for the type and timing of rehabilitation. Based on GRADE (Grading of Recommendation, Assessment, Development and Evaluation), a strong recommendation is worded as "we recommend," whereas a weaker recommendation is indicated by "we suggest. RESULTS Based on the findings from the systematic review, our recommendations were: (1) We suggest rehabilitation be offered to patients with acute spinal cord injury when they are medically stable and can tolerate required rehabilitation intensity (no included studies; expert opinion); (2) We suggest body weight-supported treadmill training as an option for ambulation training in addition to conventional overground walking, dependent on resource availability, context, and local expertise (low evidence); (3) We suggest that individuals with acute and subacute cervical SCI be offered functional electrical stimulation as an option to improve hand and upper extremity function (low evidence); and (4) Based on the absence of any clear benefit, we suggest not offering additional training in unsupported sitting beyond what is currently incorporated in standard rehabilitation (low evidence). CONCLUSIONS These guidelines should be implemented into clinical practice to improve outcomes and reduce morbidity in patients with SCI by promoting standardization of care, decreasing the heterogeneity of management strategies and encouraging clinicians to make evidence-informed decisions.

Abstract
INTRODUCTION The objective of this guideline is to outline the appropriate use of methylprednisolone sodium succinate (MPSS) in patients with acute spinal cord injury (SCI). METHODS A systematic review of the literature was conducted to address key questions related to the use of MPSS in acute SCI. A multidisciplinary Guideline Development Group used this information, in combination with their clinical expertise, to develop recommendations for the use of MPSS. Based on GRADE (Grading of Recommendation, Assessment, Development and Evaluation), a strong recommendation is worded as "we recommend," whereas a weaker recommendation is indicated by "we suggest." RESULTS The main conclusions from the systematic review included the following: (1) there were no differences in motor score change at any time point in patients treated with MPSS compared to those not receiving steroids; (2) when MPSS was administered within 8 hours of injury, pooled results at 6- and 12-months indicated modest improvements in mean motor scores in the MPSS group compared with the control group; and (3) there was no statistical difference between treatment groups in the risk of complications. Our recommendations were: (1) "We suggest not offering a 24-hour infusion of high-dose MPSS to adult patients who present after 8 hours with acute SCI"; (2) "We suggest a 24-hour infusion of high-dose MPSS be offered to adult patients within 8 hours of acute SCI as a treatment option"; and (3) "We suggest not offering a 48-hour infusion of high-dose MPSS to adult patients with acute SCI." CONCLUSIONS These guidelines should be implemented into clinical practice to improve outcomes and reduce morbidity in SCI patients.

Abstract
OBJECTIVES The objective of this study was to conduct a systematic review of the literature to address the following clinical questions: In adult patients with acute and subacute complete or incomplete traumatic SCI, (1) does the time interval between injury and commencing rehabilitation affect outcome?; (2) what is the comparative effectiveness of different rehabilitation strategies, including different intensities and durations of treatment?; (3) are there patient or injury characteristics that affect the efficacy of rehabilitation?; and (4) what is the cost-effectiveness of various rehabilitation strategies? METHODS A systematic search was conducted for literature published through March 31, 2015 that evaluated rehabilitation strategies in adults with acute or subacute traumatic SCI at any level. Studies were critically appraised individually and the overall strength of evidence was evaluated using methods proposed by the GRADE (Grades of Recommendation Assessment, Development and Evaluation) working group. RESULTS The search strategy yielded 384 articles, 19 of which met our inclusion criteria. Based on our results, there was no difference between body weight-supported treadmill training and conventional rehabilitation with respect to improvements in Functional Independence Measure (FIM) Locomotor score, Lower Extremity Motor Scores, the distance walked in 6 minutes or gait velocity over 15.2 m. Functional electrical therapy resulted in slightly better FIM Motor, FIM Self-Care, and Spinal Cord Independence Measure Self-Care subscores compared with conventional occupational therapy. Comparisons using the Toronto Rehabilitation Institute Hand Function Test demonstrated no differences between groups in 7 of 9 domains. There were no clinically important differences in Maximal Lean Test, Maximal Sidewards Reach Test, T-shirt Test, or the Canadian Occupational Performance Measure between unsupported sitting training and standard in-patient rehabilitation. CONCLUSION The current evidence base for rehabilitation following acute and subacute spinal cord injury is limited. Methodological challenges have contributed to this and further research is still needed.

Abstract
INTRODUCTION The objective of this guideline is to outline the role of magnetic resonance imaging (MRI) in clinical decision making and outcome prediction in patients with traumatic spinal cord injury (SCI). METHODS A systematic review of the literature was conducted to address key questions related to the use of MRI in patients with traumatic SCI. This review focused on longitudinal studies that controlled for baseline neurologic status. A multidisciplinary Guideline Development Group (GDG) used this information, their clinical expertise, and patient input to develop recommendations on the use of MRI for SCI patients. Based on GRADE (Grading of Recommendation, Assessment, Development and Evaluation), a strong recommendation is worded as "we recommend," whereas a weaker recommendation is indicated by "we suggest." RESULTS Based on the limited available evidence and the clinical expertise of the GDG, our recommendations were: (1) "We suggest that MRI be performed in adult patients with acute SCI prior to surgical intervention, when feasible, to facilitate improved clinical decision-making" (quality of evidence, very low) and (2) "We suggest that MRI should be performed in adult patients in the acute period following SCI, before or after surgical intervention, to improve prediction of neurologic outcome" (quality of evidence, low). CONCLUSIONS These guidelines should be implemented into clinical practice to improve outcomes and prognostication for patients with SCI.

Abstract
Acute spinal cord injury (SCI) is a traumatic event that results in disturbances to normal sensory, motor, or autonomic function and ultimately affects a patient's physical, psychological, and social well-being. The management of patients with SCI has drastically evolved over the past century as a result of increasing knowledge on injury mechanisms, disease pathophysiology, and the role of surgery. There still, however, remain controversial areas surrounding available management strategies for the treatment of SCI, including the use of corticosteroids such as methylprednisolone sodium succinate, the optimal timing of surgical intervention, the type and timing of anticoagulation prophylaxis, the role of magnetic resonance imaging, and the type and timing of rehabilitation. This lack of consensus has prevented the standardization of care across treatment centers and among the various disciplines that encounter patients with SCI. The objective of this guideline is to form evidence-based recommendations for these areas of controversy and outline how to best manage patients with SCI. The ultimate goal of these guidelines is to improve outcomes and reduce morbidity in patients with SCI by promoting standardization of care and encouraging clinicians to make evidence-informed decisions.

Abstract
STUDY DESIGN Guideline development. OBJECTIVES The objective of this study is to develop guidelines that outline how to best manage (1) patients with mild, moderate, and severe myelopathy and (2) nonmyelopathic patients with evidence of cord compression with or without clinical symptoms of radiculopathy. METHODS Five systematic reviews of the literature were conducted to synthesize evidence on disease natural history; risk factors of disease progression; the efficacy, effectiveness, and safety of nonoperative and surgical management; the impact of preoperative duration of symptoms and myelopathy severity on treatment outcomes; and the frequency, timing, and predictors of symptom development. A multidisciplinary guideline development group used this information, and their clinical expertise, to develop recommendations for the management of degenerative cervical myelopathy (DCM). RESULTS Our recommendations were as follows: (1) "We recommend surgical intervention for patients with moderate and severe DCM." (2) "We suggest offering surgical intervention or a supervised trial of structured rehabilitation for patients with mild DCM. If initial nonoperative management is pursued, we recommend operative intervention if there is neurological deterioration and suggest operative intervention if the patient fails to improve." (3) "We suggest not offering prophylactic surgery for non-myelopathic patients with evidence of cervical cord compression without signs or symptoms of radiculopathy. We suggest that these patients be counseled as to potential risks of progression, educated about relevant signs and symptoms of myelopathy, and be followed clinically." (4) "Non-myelopathic patients with cord compression and clinical evidence of radiculopathy with or without electrophysiological confirmation are at a higher risk of developing myelopathy and should be counselled about this risk. We suggest offering either surgical intervention or nonoperative treatment consisting of close serial follow-up or a supervised trial of structured rehabilitation. In the event of myelopathic development, the patient should be managed according to the recommendations above." CONCLUSIONS These guidelines will promote standardization of care for patients with DCM, decrease the heterogeneity of management strategies and encourage clinicians to make evidence-informed decisions.

Abstract
Despite the relatively low incidence of traumatic spinal cord injury (tSCI), the management and care of persons with tSCI can be resource intensive and complex, spanning multiple phases of care and disciplines. Using a simulation model built with a system level view of the healthcare system allows for prediction of the impact of interventions on patient and system outcomes from injury through to community reintegration after tSCI. As has been previously described, the Access to Care and Timing (ACT) project developed a simulation model for tSCI care using techniques from operations research. The objective of this article is to briefly describe the methodology and the application of the ACT Model, as it was used in several of the articles in this focus issue. The approaches employed in this model provide a framework to look into the complexity of interactions both within and among the different SCI programs, sites, and phases of care.

Abstract
Costs associated with initial hospitalization following spinal cord injury (SCI) are substantial, and a major driver of costs is the length of stay (LOS); that is, the time that the injured individual remains hospitalized prior to community reintegration. Our aim was to study the factors and variables that contribute to LOS following traumatic SCI. Modeling (process mapping of the SCI healthcare delivery system in Canada and discrete event simulation) and regression analysis using a national registry of individuals with acute traumatic SCI in Canada, existing databases, and peer-reviewed literature were used to examine the driver of LOS following traumatic SCI. In different jurisdictions, there is considerable variation in the definitions and methods used to determine LOS following SCI. System LOS can be subdivided into subcomponents, and progression through these is not unidirectional. Modeling reveals that healthcare organization and processes are important contributors to differences in LOS independent of patient demographics and injury characteristics. Future research is required to identify and improve understanding of contributors to LOS following traumatic SCI. This will help enhance system performance. Work in this area will be facilitated by the adoption of common terminology and definitions, as well as by the use of simulations and modeling.

Abstract
INTRODUCTION Reoperative pyeloplasty for recurrent ureteropelvic junction obstruction (UPJO) can be technically challenging and is associated with greater morbidity and lower success rates than an initial repair. Robotic-assisted laparoscopic pyeloplasty (RALP) previously has been demonstrated to be a safe and effective approach for management of recurrent UPJO; however, the length of follow-up has been limited. The objective of this study was to confirm the safety and efficacy of RALP for UPJO in children following failed previous pyeloplasty and provide clinical benchmarks for intermediate length follow-up in this patient population. METHODS An IRB approved retrospective chart review was performed for all patients undergoing reoperative RALP from June 2006 to December 2014. All cases were performed by surgeons from two institutions for persistent UPJO following failed initial pyeloplasty. Information including demographic information, radiographic studies, and operative interventions performed between the initial repair and reoperative surgery, reoperative RALP intraoperative data, postoperative clinical course and imaging studies, and subsequent interventions following reoperative RALP were extracted. RESULTS Twenty-three children underwent reoperative RALP. Eleven patients had right- and 12 left-sided repairs. Median age at reoperative RALP was 4.0 years and median interval between surgeries was 1.3 years. Indications for repeat repair included pain, infection, and/or radiographic evidence of worsening obstruction and/or deteriorating renal function. Mean operative time was 198 min from incision to port closure. Mean length of stay was 2.3 days. Six complications occurred in five patients within 30 days postoperatively, including ileus, pneumonia, and urinary tract infection. Median length of follow-up was 26 months (range 4-45 months) for all patients and 31 months (range 16-45 months) in 18 patients with >12 months of follow-up. More than 80% of patients presenting with flank pain prior to reoperative RALP had resolution of this symptom. To date, 78% of patients with >12 months of follow-up have not required further operative intervention. Excellent results have been achieved in 14 of 18 patients (78%) with sufficient postoperative follow-up in terms of length of follow-up (>12 months), symptom resolution, and/or improved imaging results. CONCLUSIONS RALP following previous pyeloplasty is technically feasible with acceptable operative times, lengths of stay, and complication rates. Reoperative RALP is our preferred modality for repair of recurrent UPJO with the vast majority of patients having successful outcomes based on imaging, resolution of symptoms, and the rare need for further intervention across an intermediate length follow-up period.

Abstract
OBJECTIVE To gain greater insight into the experience of support providers who assist and support individuals with spinal cord injury (SCI) for the performance of bowel care. DESIGN Qualitative (phenomenological) interviews and analysis. SETTING Community. PARTICIPANTS Ten support providers of individuals with SCI. MAIN OUTCOME MEASUREMENTS Themes related to supporting bowel care for individuals with SCI. RESULTS Support providers identified concerns and challenges as well as sources of satisfaction related to the provision of bowel care to individuals with SCI. Traits and characteristics of effective support providers also emerged. CONCLUSIONS Individuals with SCI often require emotional, logistical, and/or physical assistance to complete bowel care. Exploration of neurogenic bowel care from the perspective of support providers identified concerns and challenges, sources of satisfaction, and important traits and characteristics of support providers. This information can facilitate the identification of effective support providers and the provision of enhanced training and support. Interventions of this nature can improve the experience for individuals with SCI and their supports.

Abstract
OBJECTIVES To implement pressure ulcer (PU) prevention best practices in spinal cord injury (SCI) rehabilitation using implementation science frameworks. DESIGN Quality improvement. SETTING SCI Rehabilitation Center. PARTICIPANTS Inpatients admitted January 2012 to July 2013. INTERVENTIONS Implementation of two PU best practices were targeted: (1) completing a comprehensive PU risk assessment and individualized interprofessional PU prevention plan (PUPP); and (2) providing patient education for PU prevention; as part of the pan-Canadian SCI Knowledge Mobilization Network. At our center, the SCI Pressure Ulcer Scale replaced the Braden risk assessment scale and an interprofessional PUPP form was implemented. Comprehensive educational programing existed, so efforts focused on improving documentation. Implementation science frameworks provided structure for a systematic approach to best practice implementation (BPI): (1) site implementation team, (2) implementation drivers, (3) stages of implementation, and (4) improvement cycles. Strategies were developed to address key implementation drivers (staff competency, organizational supports, and leadership) through the four stages of implementation: exploration, installation, initial implementation, and full implementation. Improvement cycles were used to address BPI challenges. OUTCOME MEASURES Implementation processes (e.g. staff training) and BPI outcomes (completion rates). RESULTS Following BPI, risk assessment completion rates improved from 29 to 82%. The PUPP completion rate was 89%. PU education was documented for 45% of patients (vs. 21% pre-implementation). CONCLUSION Implementation science provided a framework and effective tools for successful pressure ulcer BPI in SCI rehabilitation. Ongoing improvement cycles will target timeliness of tool completion and documentation of patient education.

Abstract
OBJECTIVE To gain greater insight into the lived experience of individuals with spinal cord injury (SCI) and neurogenic bowel dysfunction (NBD). DESIGN Qualitative (phenomenologic) interviews and analysis. SETTING Community. PARTICIPANTS Individuals with SCI and NBD (N=19) residing in the community. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURE Concerns related to living with NBD after SCI. RESULTS Challenges related to living with SCI and NBD included costs and requirements, emotional impact, diet, education and employment, intimacy and interpersonal relations, social participation, spontaneity and daily schedule, travel, lack of appropriate and consistent assistance, loss of autonomy (independence, privacy), lack of predictability and fear of incontinence, medical complications, pain or discomfort, physical effort of the bowel routine, physical experience, and time requirements. CONCLUSIONS Living with NBD presents many challenges. When categorized according to the International Classification of Functioning, Disability and Health, identified domains include body functions and structures, activity, participation, environmental factors, and personal factors. Identified issues have implications for improving clinical management and should be assessed when determining the impact and efficacy of interventions.

Abstract
Background A patient’s journey through the health care system is influenced by clinical and system processes across the continuum of care. Methods To inform optimized access to care and patient flow for individuals with traumatic spinal cord injury (tSCI), we developed a simulation model that can examine the full impact of therapeutic or systems interventions across the care continuum for patients with traumatic spinal cord injuries. The objective of this paper is to describe the detailed development of this simulation model for a major trauma and a rehabilitation centre in British Columbia (BC), Canada, as part of the Access to Care and Timing (ACT) project and is referred to as the BC ACT Model V1.0. Findings To demonstrate the utility of the simulation model in clinical and administrative decision-making we present three typical scenarios that illustrate how an investigator can track the indirect impact(s) of medical and administrative interventions, both upstream and downstream along the continuum of care. For example, the model was used to estimate the theoretical impact of a practice that reduced the incidence of pressure ulcers by 70%. This led to a decrease in acute and rehabilitation length of stay of 4 and 2 days, respectively and a decrease in bed utilization of 9% and 3% in acute and rehabilitation. Conclusion The scenario analysis using the BC ACT Model V1.0 demonstrates the flexibility and value of the simulation model as a decision-making tool by providing estimates of the effects of different interventions and allowing them to be objectively compared. Future work will involve developing a generalizable national Canadian ACT Model to examine differences in care delivery and identify the ideal attributes of SCI care delivery.

Abstract
The long-term impact of spinal cord injury (SCI) on the health care system imposes a need for greater efficiency in the use of resources and the management of care. The Access to Care and Timing (ACT) project was developed to model the health care delivery system in Canada for patients with traumatic SCI. Techniques from Operations Research, such as simulation modeling, were used to predict the impact of best practices and policy initiatives on outcomes related to both the system and patients. These methods have been used to solve similar problems in business and engineering and may offer a unique solution to the complexities encountered in SCI care delivery. Findings from various simulated scenarios, from the patients' point of injury to community re-integration, can be used to inform decisions on optimizing practice across the care continuum. This article describes specifically the methodology and implications of producing such simulations for the care of traumatic SCI in Canada. Future publications will report on specific practices pertaining to the access to specialized services and the timing of interventions evaluated using the ACT model. Results from this type of research will provide the evidence required to support clinical decision making, inform standards of care, and provide an opportunity to engage policymakers.

Abstract
OBJECTIVE To assess efficacy of an interdisciplinary pain program adapted for persons with spinal cord injury (SCI) and chronic pain. DESIGN Prospective cohort. SETTING University-affiliated rehabilitation hospital. PARTICIPANTS Twenty-two persons with traumatic or nontraumatic SCI and chronic pain of at least 6 months' duration. METHODS Subjects participated in an interdisciplinary pain program consisting of biweekly group sessions for 10 consecutive weeks. Sessions incorporated patient education on chronic pain and associated pain mechanisms, cognitive behavioral therapy, self-management strategies (eg, energy conservation, ergonomics, goal setting, stress management, anger management, and coping skills), group discussions and activities, and either exercise or guided relaxation at the end of each session. MAIN OUTCOME MEASURES Multidimensional Pain Inventory SCI, Coping Inventory of Stressful Situations, Pain Stages of Change Questionnaire, and Life Satisfaction Questionnaire. RESULTS After participation in an interdisciplinary pain program, persons with SCI and chronic neuropathic pain demonstrated increased involvement in learning and maintenance of coping strategies for chronic pain. Participation also led to less pain interference in daily life and a greater sense of control over one's life. CONCLUSIONS Participation in an interdisciplinary pain program does not reduce pain severity, but it can help persons with SCI and chronic neuropathic pain cope with pain, lessen interference of pain, and improve their sense of control.

Abstract
OBJECTIVES To develop an International Spinal Cord Injury (SCI) Musculoskeletal Basic Data Set as part of the International SCI Data Sets to facilitate consistent collection and reporting of basic musculoskeletal findings in the SCI population. SETTING International. METHODS A first draft of an SCI Musculoskeletal Basic Data Set was developed by an international working group. This was reviewed by many different organizations, societies and individuals over 9 months. Revised versions were created successively. RESULTS The final version of the International SCI Musculoskeletal Basic Data Set contains questions on neuro-musculoskeletal history before spinal cord lesion; presence of spasticity/spasms; treatment for spasticity within the last 4 weeks; fracture(s) since the spinal cord lesion; heterotopic ossification; contracture; the location of degenerative neuromuscular and skeletal changes due to overuse after SCI; SCI-related neuromuscular scoliosis; the method(s) used to determine the presence of neuromuscular scoliosis; surgical treatment of the scoliosis; other musculoskeletal problems; if any of the musculoskeletal challenges above interfere with activities of daily living. Instructions for data collection and the data collection form are freely available on the International Spinal Cord Society (ISCoS) website (www.iscos.org.uk). CONCLUSION The International SCI Musculoskeletal Basic Data Set will facilitate consistent collection and reporting of basic musculoskeletal findings in the SCI population.

Abstract
OBJECTIVE Treatment response in late-life depression has been linked to cerebrovascular disease notably via the vascular depression hypothesis. This study investigated the relationship between endothelial function and atherosclerosis and treatment response to antidepressant monotherapy. METHODS Twenty five patients with late-life depression were compared with 21 non-depressed control subjects in a case control study. Nine of the depressed subjects were responders to antidepressant monotherapy and 16 were not. Vascular measures included assessment of carotid intima media thickness (IMT) representing atherosclerosis and biopsied small artery dilatation to acetylcholine to assess endothelial function in a subset of subjects. RESULTS There were no group differences in vascular risks or sociodemographic variables. There was a significant group difference (responders versus non-responders versus controls) on both IMT and endothelial function (p < 0.01 and p < 0.05, respectively) with a significant difference between controls and non-responders (p < 0.001) on IMT and between controls and responders (p < 0.05) and control versus non-responders (p < 0.05) on endothelial function but no significant difference between responders and non-responders. On both IMT and endothelial function, there was a gradient across groups, with control subjects having best vascular structure or function, non-responders worse and responders in-between. CONCLUSIONS The results are consistent with a hypothesis that poorer antidepressant response in later life depressive disorder may be linked to an underlying vascular dysfunction and pathology. The study is small, and the results require replication but if confirmed, trials with vasoprotective medication aimed at improving vascular function in order to alter the prognosis of late-life depression would be a rational development.

Abstract
STUDY DESIGN Performance improvement initiative. OBJECTIVES To improve efficiency of spinal cord rehabilitation by reducing length of stay (LOS) while maintaining or improving patient outcomes. SETTING Academic hospital in Canada. METHODS LOS benchmarking was completed using national comparator data from the Canadian Institute for Health Information (CIHI). Clinical decision-making tools were developed to support implementation and sustainability. A standardized 'tentative discharge date' calculator was created to establish objective LOS targets. Defined discharge criteria and an accompanying clinical decision tree were developed to support team decision making and improve transparency. A revised patient census tool was also implemented to improve team communication and facilitate data collection. The initiative was implemented in March 2010 and the following metrics were evaluated: LOS, Functional Independence Measure (FIM) change and FIM efficiency. RESULTS Outcomes are reported for the 2010/11 fiscal year, and compared with the two prior fiscal years. Mean LOS for individuals undergoing initial inpatient rehabilitation was 71.5 days for 2010/11, a 14 and 17% reduction compared with the 2008/09 and 2009/10 fiscal years, respectively. While LOS decreased, FIM change increased 9 and 16% compared with 2008/09 and 2009/10, respectively. Similarly, FIM efficiency increased 54 and 32% compared with 2008/09 and 2009/10. CONCLUSION The use of benchmarking and decision support tools improved rehabilitation efficiency while increasing standardization in practice and transparency in LOS determination.

Abstract
Spinal cord injury (SCI) is a sudden, life-altering event. Injury severity and accompanying recovery vary considerably from individual to individual. The most important determinant of prognosis is whether an injury is clinically complete or incomplete. While approximately 10-20% of complete injuries convert to incomplete during the first year post-injury, the magnitude of motor recovery following complete SCI is limited or absent. Robust functional motor recovery (e.g., weight-bearing, ambulation) distal to the zone of injury is rare. Recovery following incomplete SCI is particularly variable, and anywhere from 20% to 75% of individuals will recover some degree of walking capacity by 1 year post-injury. This is related to presenting injury severity (American Spinal Injury Association Impairment Scale grade); however, even 20-50% of individuals who present as motor complete, sensory incomplete will walk in some capacity by 1 year post-injury. Regardless, for both complete and incomplete injuries, the majority of recovery is observed during the initial 9-12 months, with a relative plateau reached by 12-18 months post-injury. Magnetic resonance imaging (MRI) provides valuable adjunct information when a bedside clinical assessment cannot be completed. The presence of intramedullary hemorrhage and extended segments of edema have been associated with clinically complete SCI.

Abstract
Great strides have been made in reducing morbidity and mortality following spinal cord injury (SCI), and improving long-term health and community participation; however, this progress has not been uniform across the globe. This review highlights differences in global epidemiology of SCI and the ongoing challenges in meeting the needs of individuals with SCI in the developing world, including post-disaster. Significant disparities persist, with life expectancies of 2 years or less not uncommon for persons living with paraplegia in many developing countries. The international community has an important role in improving access to appropriate care following SCI worldwide.

Abstract
Background. The Walking Index for Spinal Cord Injury II (WISCI II) is a hierarchical scale that measures improvements in walking following spinal cord injury (SCI). The WISCI II has good face validity, concurrent validity, and reliability following acute SCI; however, psychometric properties need to be determined for chronic SCI. Because prior studies have demonstrated a relationship between lower-extremity motor scores (LEMS) and walking, outcome measures for walking should demonstrate a linkage between the underlying impairment (weakness) and walking—convergent validity. Objective. To determine convergent validity and reproducibility of the WISCI II. Methods. Self-selected and maximum WISCI levels were assessed for 76 patients with chronic SCI (34 paraplegia, 42 tetraplegia); 10-m walking speeds were calculated. Convergent validity was assessed by correlating WISCI II levels to LEMS and walking speed. Reproducibility was assessed with the intraclass correlation coefficient (ICC) and the smallest real difference (SRD). Results. Convergent validity of the self-selected and maximum WISCI II with LEMS was moderate for paraplegia (ρ = 0.479 and ρ = 0.533) and strong for tetraplegia (ρ = 0.852 and ρ = 0.816). Tetraplegia, but not paraplegia, demonstrated convergent validity of walking speed at the self-selected and maximum WISCI levels with LEMS (ρ = 0.752 and ρ = 0.813). WISCI reproducibility was excellent (self-selected ICC = 0.994; maximum ICC = 0.995), resulting in SRDs of 0.785 (self-selected) and 0.597 (maximum), suggesting that a change of one WISCI level can be interpreted as real in a chronic patient. Conclusions. Results suggest that the WISCI II should be a very useful outcome measure for detecting changes in walking function following chronic SCI.

Abstract
Current evidence suggests that significant morphological changes occur in nerve-muscle connections caudal to spinal cord injury (SCI). To determine whether neuromuscular junction (NMJ) function is compromised after SCI, we investigated the contribution of NMJ failure to hindlimb muscle fatigue in control and spinalized adult rats. Repetitive supramaximal nerve stimulation was applied to two muscle-nerve preparations: medial gastrocnemius (MG)-tibial and tibialis anterior (TA)-peroneal. NMJ transmission failure was evident in control and SCI animals after repetitive stimulation. At 2 wk post-SCI, NMJ transmission failure was greater in SCI animals compared with controls, but the difference was not significant (P = 0.205 for the MG and P = 0.053 for the TA). At 6 wk post-SCI, there was a significant but small difference in NMJ transmission failure for the TA between control and spinal animals. These results demonstrate that, although there may be a mild decrement in NMJ function, NMJ transmission remains largely intact for supramaximal nerve stimulation.

Abstract
BACKGROUND AND PURPOSE How early spinal cord injury (SCI) lesions evolve in patients after injury is unknown. The purpose of this study was to characterize the early evolution of spinal cord edema and hemorrhage on MR imaging after acute traumatic SCI. MATERIALS AND METHODS We performed a retrospective analysis of 48 patients with clinically complete cervical spine injury. Inclusion criteria were the clear documentation of the time of injury and MR imaging before surgical intervention within 72 hours of injury. The length of intramedullary spinal cord edema and hemorrhage was assessed. The correlation between time to imaging and lesion size was determined by multiple regression analysis. Short-interval follow-up MR imaging was also available for a few patients (n = 5), which allowed the direct visualization of changes in spinal cord edema. RESULTS MR imaging demonstrated cord edema in 100% of patients and cord hemorrhage in 67% of patients. The mean longitudinal length of cord edema was 10.3 +/- 4.0 U, and the mean length of cord hemorrhage was 2.6 +/- 2.0 U. Increased time to MR imaging correlated to increased spinal cord edema length (P = .002), even after accounting for the influence of other variables. A difference in time to MR imaging of 1.2 days corresponded to an average increase in cord edema by 1 full vertebral level. Hemorrhage length was not affected by time to imaging (P = .825). A temporal increase in the length of spinal cord edema was confirmed in patients with short-interval follow-up MR imaging (P = .003). CONCLUSION Spinal cord edema increases significantly during the early time period after injury, whereas intramedullary hemorrhage is comparatively static.

Abstract
OBJECTIVES To assess (1) the frequency and magnitude of differences between self-selected and maximal walking capacity following spinal cord injury (SCI) by using the Walking Index for Spinal Cord Injury (WISCI) and (2) how these levels differ in efficiency and velocity. DESIGN Prospective cohort. SETTING Academic medical center. PARTICIPANTS Fifty people with chronic incomplete SCI. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Subjects ambulated at the level used in the community (self-selected WISCI) and the highest level possible (maximal WISCI). Velocity (in m/s), Physiological Cost Index (PCI), and Total Heart Beat Index (THBI) were calculated. Differences were compared using the paired t test (parametric) or Wilcoxon signed-rank test (nonparametric). RESULTS For 36 subjects, maximal WISCI was higher than self-selected WISCI; 21 subjects showed an increase of 3 levels or more. Ambulatory velocity was higher for self-selected WISCI compared with maximal WISCI (.68 m/s vs .56 m/s, P<.001). PCI and THBI at self-selected WISCI were lower than at maximal WISCI (PCI, 0.99 beats/m vs 1.48 beats/m, P<.001; THBI, 3.39 beats/m vs 4.75 beats/m, P<.001). CONCLUSIONS Many people with chronic SCI are capable of ambulating at multiple levels. For these people, ambulation at self-selected WISCI was more efficient as evidenced by greater velocity and decreased PCI and THBI. The findings have implications for assessing walking capacity within the context of clinical trials.

Abstract
STUDY DESIGN Retrospective study comparing spinal cord injury (SCI) lesion characteristics in methylprednisolone (MPS) treated versus untreated patients as demonstrated by magnetic resonance (MR) imaging. OBJECTIVE Determine if the administration of MPS immediately following SCI affects lesion severity. SUMMARY OF BACKGROUND DATA The administration of MPS in the setting of acute SCI has become controversial. Since magnetic resonance imaging (MRI) is sensitive for the detection of spinal cord edema and hemorrhage, changes in lesion characteristics would support a biologic effect due to MPS. METHODS Patients with cervical spinal injury treated with the recommended dose of methylprednisolone (bolus 30 mg/kg + 5.4 mg/kg per hour over 24 hours) initiated within 8 hours of injury were compared to historical controls that did not receive steroids. All patients (n = 82) sustained clinically complete SCI (ASIA Grade A) and underwent MRI on the same 1.5 Tesla unit. The length of spinal cord edema, presence/absence of intramedullary hemorrhage, and length of intramedullary hemorrhage were measured on T2-weighted and gradient echo MR images. Comparisons of lesion severity were then made between untreated and treated subjects. RESULTS Forty-eight of 82 patients with complete injuries received MPS therapy. After accounting for differences in the mean age of the treatment and control groups, multiple regression analysis demonstrated a persistent reduction in the mean length of intramedullary hemorrhage, 2.6 U in the treatment group versus 4.4 U in the control group (P = 0.04). Although there was a reduction in the number of patients exhibiting spinal cord hemorrhage in the treated group compared with the untreated group (65% vs. 91%), this result was not statistically significant (P = 0.16). There was no statistically significant effect of MPS treatment on the mean length of the spinal cord edema between treated versus untreated subjects (10.3 vs. 12.0, respectively, P = 0.85). CONCLUSIONS MRI suggests MPS therapy in the acute phase of spinal cord injury may decrease the extent of intramedullary spinal cord hemorrhage.

Abstract
Fibrillation potentials and positive sharp waves (spontaneous potentials) are the electrophysiological hallmark of denervated skeletal muscle, and their detection by intramuscular electromyography (EMG) is the clinical gold standard for diagnosing denervated skeletal muscle. Surprisingly, spontaneous potentials have been described following human and experimental spinal cord injury (SCI) in muscles innervated by spinal cord segments distal to the level of direct spinal injury. To determine whether electrophysiological abnormalities are improved by two therapeutic interventions for experimental SCI, neurotrophic factors and exercise training, we studied four representative hindlimb muscles in adult domestic short-hair cats following complete transection of the spinal cord at T11-T12. In untreated cats, electrophysiological abnormalities persisted unchanged for 12 weeks postinjury, the longest duration studied. In contrast, fibrillations and positive sharp waves largely resolved in animals that underwent weight-supported treadmill training or received grafts containing fibroblasts genetically modified to express brain-derived neurotrophic factor and neurotrophin-3. These findings suggest that neurotrophins and activity play an important role in the poorly understood phenomenon of fibrillations distal to SCI.

Abstract
Neuromuscular junctions (NMJs) innervated by motor neurons below spinal cord injury (SCI) have been reported to remain intact despite the interruption of supraspinal pathways and the resultant loss of activity. Here we report notably heterogeneous NMJ responses to SCI that include overt synapse disassembly. Complete transection of the thoracic spinal cord of adult rats evoked massive sprouting of nerve terminals in a subset of NMJs in ankle flexors, extensor digitorum longus, and tibialis anterior. Many of these synapses were extensively disassembled 2 weeks after spinal transection but by 2 months had reestablished synaptic organization despite continuous sprouting of their nerve terminals. In contrast, uniform and persistent loss of acetylcholine receptors (AChRs) was evident in another subset of NMJs in the same flexors, which apparently lacked terminal sprouting and largely maintained terminal arbors. Other synapses in the flexors, and almost all the synapses in the ankle extensors, medial gastrocnemius, and soleus, remained intact, with little pre- or postsynaptic alteration. Additional deafferentation of the transected animals did not alter the incidence or regional distribution of either type of the unstable synapses, whereas cycling exercise diminished their incidence. The muscle- and synapse-specific responses of NMJs therefore reflected differential sensitivity of the NMJs to inactivity rather than to differences in residual activity. These observations demonstrate the existence of multiple subpopulations of NMJs that differ distinctly in pre- and postsynaptic vulnerability to the loss of activity and highlight the anatomical instability of NMJs caudal to SCI, which may influence motor deficit and recovery after SCI.

Abstract
BACKGROUND AND PURPOSE The incidence of blunt traumatic vertebral artery dissection/thrombosis varies widely in published trauma series and is associated with spinal trauma. The purpose of this study was to determine the frequency of traumatic vertebral artery thrombosis (VAT) in cervically injured patients by using routine MR angiography (MRA) and MR imaging and identify associations with the severity of neurologic injury. METHODS A retrospective review of 1283 patients with nonpenetrating cervical spine fractures with or without an associated spinal cord injury (SCI) was performed. Imaging consisted of routine cervical MR imaging and 2D time-of-flight MRA of the neck. The cervical injury level, neurologic level of injury, and American Spinal Injury Association (ASIA) grade were recorded. RESULTS In this study, 632 patients met the inclusion criteria, 83 (13%) of whom had VAT on the admission MR imaging/MRA. Fifty-nine percent (49/83) of VAT patients had an associated SCI. VAT was significantly more common in motor-complete patients (ASIA A and B, 20%) than in neurologically intact (ASIA E, 11%) cervical spine-injured patients (P = .019). VAT incidence was not significantly different between motor-incomplete (ASIA C and D, 10%) and neurologically intact (ASIA E, 11%) cervical spine-injured patients (P = .840). CONCLUSION The absence of neurologic symptoms in a patient with cervical spine fracture does not preclude VAT. VAT associated with cervical spinal injury occurs with similar frequency in both neurologically intact (ASIA E) and motor-incomplete patients (ASIA C and D) but is significantly more common in motor-complete SCI (ASIA A and B).

Abstract
OBJECTIVE To assess sacral and lower-extremity pinprick preservation as prognostic indicators for ambulation in motor complete, sensory incomplete spinal cord injury (SCI). DESIGN Retrospective analysis. SETTING Twenty-eight tertiary care centers in the United States and Canada. PARTICIPANTS Subjects (N=131; mean age, 31.6y) with motor complete, sensory incomplete SCI. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURE Ambulation at 26 and 52 weeks postinjury (modified Benzel scale). RESULTS A higher percentage of subjects with sacral pinprick preservation at baseline were ambulating at 26 (39.4% vs 28.3%) and 52 weeks (53.6% vs 41.5%). This finding did not reach statistical significance. The presence of sacral pinprick preservation at 4 weeks postinjury was significant for predicting ambulation at 52 weeks postinjury (36.0% vs 4.4%, P =.011) and approached significance at 26 weeks (15.2% vs 0.0%, P =.056). Significant differences in ambulation rates were also observed between subjects, based on the presence of baseline lower-extremity pinprick preservation (>/=50% of lower-extremity L2-S1 dermatomes) at both 26 (50.0% vs 28.8%, P =.048) and 52 weeks (66.7% vs 40.3%, P =.023) after injury. CONCLUSIONS Baseline lower-extremity pinprick preservation and sacral pinprick preservation at 4 weeks postinjury are associated with an improved prognosis for ambulation.

Abstract
Spinal shock has been of interest to clinicians for over two centuries. Advances in our understanding of both the neurophysiology of the spinal cord and neuroplasticity following spinal cord injury have provided us with additional insight into the phenomena of spinal shock. In this review, we provide a historical background followed by a description of a novel four-phase model for understanding and describing spinal shock. Clinical implications of the model are discussed as well.

Abstract
We intend to demonstrate that future treatment strategies in spinal cord injury (SCI) rehabilitation to restore function (SCI rehabilitation) should be based on the success of rigorous clinical trials with demonstrated effective interventions. Knowing the course of neurological recovery, its mechanism, and its measures will be essential in designing and executing these trials. We reviewed selected recovery outcomes and measures from multicenter studies and a large SCI database. The accuracy of baseline examinations in the first days following injury is critical to demonstrating changes in neurological recovery. Recovery of one neurologic level in subjects with tetraplegia depends on the severity of the injury, the initial level of the injury, and the strength of muscles below the level of injury. Motor recovery of the upper limbs typically correlates with self-care function. Neurological recovery following SCI often correlates with an increase in function and walking in addition to self-care. In subjects with paraplegia, predicting recovery of walking is possible based on the initial 1-week sensory and motor examination. Although initial neurological findings correlate with neurological and functional-recovery outcomes in large populations of 3,500 subjects reported by the Model SCI System centers in the United States, improved outcome measures for walking are needed. The Walking Index for Spinal Cord Injury (WISCI) has recently demonstrated criterion validity and increased sensitivity and responsiveness to change in neurological/walking function in subjects with SCI. The WISCI scale correlated well with measures in use to determine improved walking function regarding walking speed, lower-limb motor scores, and other measures. Demonstrating improved neurologic and functional outcomes following SCI requires accurate neurologic and sensitive functional measures.

Abstract
OBJECTIVE To examine the contributions of the Model Spinal Cord Injury System (MSCIS) program to the evaluation and care of individuals with spinal cord injury (SCI) and to acknowledge today's challenges to chart the future course of the MSCIS. METHODS Retrospective review of the literature and prospective development of consensus by task force members and consultants. Integration of recent reported findings from panel presentations and publications regarding the MSCIS 2000 through 2005. FINDINGS Significant strides have been made toward the improvement of care for individuals with SCI, which can be attributed to the quality of clinical investigation and education. This has been achieved through the leadership of MSCIS directors in partnership with members from national and international voluntary organizations. These efforts include more than 2,000 peer-reviewed publications from the MSCIS, which have served as a basis for practice guidelines in the field. Although much has been accomplished with regard to reducing medical and behavioral complications, mortality, and length of stay in the hospital and increasing successful return to the community, more is needed. CONCLUSION The MSCIS has a unique opportunity to provide solutions because of its world-renowned database and center, outcome measures, and infrastructure for trials. To maximize this opportunity, the MSCIS must continue to address the appropriate investigational and service issues by defining the best approach to data collection, rigorous clinical studies, and behavioral strategies in the next decade.

Abstract
Patients with incomplete spinal cord injuries can spontaneously recover motor function. Because of this, phase I and II trials of invasive interventions for acute spinal cord injury will likely involve neurologically complete injuries. It is therefore important to reliably identify complete injuries as early as possible. We examined the reliability of the early examination in motor complete spinal cord injuries by retrospectively analyzing the stability of baseline neurological status determined within 2 days of injury in 103 subjects. Baseline neurological status was compared to neurological status at follow-up, preferably within one week (101 of 103 subjects). When available (n = 68), neurological status at 1 year or later was also compared. Overall, 6.2% (5/81) of motor complete, sensory complete (ASIA A) subjects converted to motor complete, sensory incomplete status (ASIA B) between the initial and follow-up assessments; however, none exhibited motor recovery (ASIA C or D). At initial follow-up, 9.3% (4/43) of ASIA A subjects with factors affecting examination reliability were reclassified as ASIA B injuries compared to 2.6% (1/38) of ASIA A subjects without such factors. At year 1 or later, 6.7% (2/30) of ASIA A subjects without factors affecting exam reliability, converted to ASIA B status. None developed volitional motor function below the zone of injury. For subjects with factors affecting exam reliability, 17.4% (4/23) of ASIA A subjects converted to incomplete status and 13.0% (3/23) regained some motor function by one year or later (ASIA C or D). These data suggest that it is possible to identify within 48 h of injury, a subset of patients with a negligible chance for motor recovery who would be suitable candidates for future clinical trials of invasive treatments.

Abstract
OBJECTIVE To determine the incidence and etiology of lower motor neuron (LMN) vs upper motor neuron (UMN) lesions in patients with complete thoracic and lumbar spinal cord injuries (SCI). DESIGN Retrospective chart review. SETTING A regional Model Spinal Cord Injury System center. METHODS A consecutive sample of medical records of patients with lower thoracic and upper lumbar (T7-L3) complete SCI admitted from 1979 through 1996 was systematically reviewed. Of the 306 patients evaluated, 156 subjects met inclusion criteria. The incidence and etiology of LMN vs UMN lesions were determined for the following neurologic levels: T7-T9, T10-T12, L1-L3. Lesions were classified as LMN, UMN, or mixed on the basis of the presence or absence of (1) the bulbocavernosus reflex, (2) lower limb deep tendon reflexes below the neurologic level of injury, and (3) the Babinski sign. RESULTS The incidences of LMN, UMN, and mixed lesions in the T7-T9, T10-T12, and L1-L3 groups were as follows: T7-T9 group (7.3% LMN, 85.5% UMN, 7.3% mixed), T10-T12 group (57% LMN, 17.7% UMN, 25.3% mixed),L1-L3 group (95.5% LMN, 0.0% UMN, 4.5% mixed). Etiology of injury did not significantly influence the likelihood of a LMN lesion. CONCLUSIONS One cannot determine the type of lesion (UMN vs LMN) on the basis of the neurological level of injury. A detailed clinical examination, including sacral reflexes, is required. This has important prognostic and therapeutic implications for bowel, bladder, and sexual function, as well as mobility. Distinguishing UMN lesions from LMN lesions is also essential for evaluating new interventions in clinical trials for UMN pathology.
