International standards for neurological classification of spinal cord injury (Revised 2011)

This article represents the content of the booklet, International Standards for Neurological Classification of Spinal Cord Injury, revised 2011, published by the American Spinal Injury Association (ASIA). For further explanation of the clarifications and changes in this revision, see the accompanying article (Kirshblum S., et al. J Spinal Cord Med. 2011:doi 10.1179/107902611X13186000420242 n nThe spinal cord is the major conduit through which motor and sensory information travels between the brain and body. The spinal cord contains longitudinally oriented spinal tracts (white matter) surrounding central areas (gray matter) where most spinal neuronal cell bodies are located. The gray matter is organized into segments comprising sensory and motor neurons. Axons from spinal sensory neurons enter and axons from motor neurons leave the spinal cord via segmental nerves or roots. n nIn the cervical spine, there are 8 nerve roots. Cervical roots of C1-C7 are named according to the vertebra above which they exit (i.e. C1 exits above the C1 vertebra, just below the skull and C6 nerve roots pass between the C5 and C6 vertebrae) whereas C8 exists between the C7 and T1 vertebra; as there is no C8 vertebra. The C1 nerve root does not have a sensory component that is tested on the International Standards Examination. n nThe thoracic spine has 12 distinct nerve roots and the lumbar spine consists of 5 distinct nerve roots that are each named accordingly as they exit below the level of the respective vertebrae. The sacrum consists of 5 embryonic sections that have fused into one bony structure with 5 distinct nerve roots that exit via the sacral foramina. The spinal cord itself ends at approximately the L1-2 vertebral level. The distal most part of the spinal cord is called the conus medullaris. The cauda equina is a cluster of paired (right and left) lumbosacral nerve roots that originate in the region of the conus medullaris and travel down through the thecal sac and exit via the intervertebral foramen below their respective vertebral levels. There may be 0, 1, or 2 coccygeal nerves but they do not have a role with the International Standards examination in accordance with the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI). n nEach root receives sensory information from skin areas called dermatomes. Similarly each root innervates a group of muscles called a myotome. While a dermatome usually represents a discrete and contiguous skin area, most roots innervate more than one muscle, and most muscles are innervated by more than one root. n nSpinal cord injury (SCI) affects conduction of sensory and motor signals across the site(s) of lesion(s), as well as the autonomic nervous system. By systematically examining the dermatomes and myotomes, as described within this booklet, one can determine the cord segments affected by the SCI. From the International Standards examination several measures of neurological damage are generated, e.g., Sensory and Motor Levels (on right and left sides), NLI, Sensory Scores (Pin Prick and Light Touch), Motor Scores (upper and lower limb), and ZPP. This booklet also describes the ASIA (American Spinal Injury Association) Impairment Scale (AIS) to classify the severity (i.e. completeness) of injury. n nThis booklet begins with basic definitions of common terms used herein. The section that follows describes the recommended International Standards examination, including both sensory and motor components. Subsequent sections cover sensory and motor scores, the AIS classification, and clinical syndromes associated with SCI. For ease of reference, a worksheet (Appendix 1) of the recommended examination is included, with a summary of steps used to classify the injury (Appendix 2). A full-size version for photocopying and use in patient records has been included as an enclosure and may also be downloaded from the ASIA website (www.asia-spinalinjury.org). Additional details regarding the examination and e-Learning training materials can also be obtained from the website15.

Reference for the 2011 revision of the international standards for neurological classification of spinal cord injury

Abstract The latest revision of the International Standards for the Neurological Classification of Spinal Cord Injury (ISNCSCI) was available in booklet format in June 2011, and is published in this issue of the Journal of Spinal Cord Medicine. The ISNCSCI were initially developed in 1982 to provide guidelines for the consistent classification of the neurological level and extent of the injury to achieve reliable data for clinical care and research studies. This revision was generated from the Standards Committee of the American Spinal Injury Association in collaboration with the International Spinal Cord Societys Education Committee. This article details and explains the updates and serves as a reference for these revisions and clarifications.

2009 Review and Revisions of the International Standards for the Neurological Classification of Spinal Cord Injury

Abstract Summary: The International Standards for the Neurological Classification of Spinal Cord Injury (ISNCSCI) were recently reviewed by the ASIAs Education and Standards Committees, in collaboration with the International Spinal Cord Societys Education Committee. Available educational materials for the ISNCSCI were also reviewed. The last citable reference for the ISNCSCIs methodology is the ISNCSCI Reference Manual, published in 2003 by ASIA. The Standards Committee recommended that the numerous items that were revised should be published and a precedent established for a routine published review of the ISNCSCI. The Standards Committee also noted that, although the 2008 reprint pocket booklet is current, the reference manual should be revised after proposals to modify/revise the ASIA Impairment Scale (AIS as modified from Frankel) are considered. In addition, the Standards Committee adopted a process for thorough and transparent review of requests to revise the ISNCSCI.

Updates for the International Standards for Neurological Classification of Spinal Cord Injury

The International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) is the most widely used classification in the field of spinal cord injury medicine. Since its first publication in 1982, multiple revisions refining the recommended examination, scaling, and classification have taken place to improve communication, consistency, and clarity. This article describes a brief historical perspective on the development and changes over the years leading to the current ISNCSCI, detailing the most recent updates of 2011 and the worksheet 2013 as well as issues facing the ISNCSCI for the future.

Protocol management of late-stage pressure ulcers: a 5-year retrospective study of 101 consecutive patients with 179 ulcers.

Background: Despite a 12 to 82 percent pressure ulcer recurrence rate, no standard protocol exists for postoperative management. The authors reviewed a single surgeons experience using a standard protocol: surgery and immediate reconstruction regardless of nutrition, intraoperative bone culture guiding postoperative antibiotic use, and hospital admission for 3 weeks of flat bedrest before graduated sitting. Methods: A 5-year retrospective chart review was performed on consecutive surgically treated pressure ulcers. A search of billing records identified 101 patients with 179 ulcers. Data abstracted included demographics, comorbidities, location and stage of ulcers, treatment history with outcomes, and laboratory data. Results: Seventy-nine percent of the patients were men with a mean age of 49.4 years. Of 179 ulcers, 49.7 percent were ischial, 26.8 percent were sacral, and 19 percent were trochanteric; 87.7 percent of ulcers were stage 4. Primary closure was performed on 45.8 percent; others underwent flap closure. There was no correlation between positive bone cultures and recurrence or complications. The overall recurrence rate was 16.8 percent at a mean period of 435.9 days. New ulcer occurrence was 14.5 percent and the complication rate was 17.3 percent. Admission prealbumin and albumin did not correlate with recurrence or complication. Mean follow-up was 629 days. Conclusions: A standard clinical pathway for pressure ulcer treatment improves long-term outcomes; the authors protocols validity is supported by low recurrence and complication rates. Nutritional data do not predict outcome. Intraoperative bone cultures are the most valid method of diagnosing osteomyelitis; results should not delay definitive treatment. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

International Standards for Neurological Classification of Spinal Cord Injury: Cases With Classification Challenges

Abstract The International Standards for the Neurological Classification of Spinal Cord Injury (ISNCSCI) is routinely used to determine the levels of injury and to classify the severity of the injury. Questions are often posed to the International Standards Committee of the American Spinal Injury Association regarding the classification. The committee felt that disseminating some of the challenging questions posed, as well as the responses, would be of benefit for professionals utilizing the ISNCSCI. Case scenarios that were submitted to the committee are presented with the responses as well as the thought processes considered by the committee members. The importance of this documentation is to clarify some points as well as update the SCI community regarding possible revisions that will be needed in the future based upon some rules that require clarification.

Transitioning Adolescents and Young Adults with a Chronic Health Condition to Adult HealthCare – An Exemplar Program

&NA; Pediatric specialists have successfully improved the longevity and quality of life of many children with chronic health conditions. As these children reach adolescence and young adulthood, the scope of their concomitant medical problems often include those typically seen in older patients. As a result, these individuals need continuing quality health care in focused adult healthcare facilities. This article describes the effective partnership between pediatric and adult healthcare providers to create and implement an exemplar Spina Bifida Transition Program. The processes, strategies and tools discussed are likely to be useful to other healthcare professionals interested in developing pediatric to adult transition programs for adolescents and young adults with chronic health conditions.

Transitioning Adolescents and Young Adults with Spina Bifida to Adult Healthcare: Initial Findings from a Model Program

Purpose: The Spina Bifida Transition Project (SBTP) was developed by partners from pediatric and adult health care settings using existing best practice information in an effort to transition adolescents to adult health care providers. The purpose of this manuscript is to present the results of an initial evaluation of the SBTP from the adolescent/young adult (AYA) and family perspective. Design and Methods: Qualitative evaluation data were obtained from telephone interviews with 40 individuals (24 AYA and 16 parents representing 28 families) two‐three weeks after initial adult clinic visits using a semi‐structured interview guide. Findings: Interview analysis yielded six overall themes: Positive experience, Developing Trust, Unexpected Benefits, Communication, Potential Worries, and Suggestions for Improvement. The study supported both the effectiveness of the SBTP as well as patient desire for earlier initiation of transition activities Conclusion and Clinical Relevance: SBTP is well‐received by participants and their parents and may be useful model for other chronic health conditions.

Acute visual loss in a patient with spinal cord injury

IntroductionPatients with spinal cord injury (SCI), especially those with injury at and above T6, are prone to transient episodes of hypertension induced by noxious triggers below the level of SCI, known as autonomic dysreflexia (AD). An uncommonly reported presentation of AD is posterior reversible encephalopathy syndrome (PRES).Case PresentationA 50-year-old male with the history of paraplegia from SCI presented with sepsis secondary to baclofen pump and urinary tract infections. On hospital day 4, he developed acute bilateral vision loss. The next morning he had a generalized-tonic-clonic seizure followed by cardiac arrest, with return of spontaneous circulation following resuscitation. Magnetic resonance imaging brain demonstrated multifocal areas of hyperintensity on T2 fluid-attenuated inversion recovery sequence, most pronounced in the occipital lobes. Systolic blood pressures (SBP) were under 180u2009mmHg throughout hospital stay but above his baseline (SBP 90u2009mmHg). PRES was diagnosed on the basis of clinical and radiologic evidence. With strict blood pressure (BP) control, there was resolution of visual abnormalities, headaches, encephalopathy, and seizures.DiscussionAlthough PRES has been most commonly described in malignant hypertension, it can be seen in patients with normotension or moderate hypertension who have low baseline BPs, such as patients with SCI. These patients are prone to AD due to imbalanced sympathetic outflow to vasculature below the level of injury caused by noxious stimulus. This results in massive regional vasoconstriction leading to an uncontrolled rise in BP above baseline. This episode of PRES could have been prevented by identifying patient’s risk, recognizing early signs and potential triggers of AD, and implementing aggressive treatment of the underlying noxious stimuli.
