Michael Keith MD Ann Bryden OTRL Cleveland Ohio USA Redefining Tetraplegia
SCI Classification • An important component in determining potential interventions is the classification of the level of injury • Classification schemes provide a common platform for understanding the degree of function associated with the level of SCI
SCI Classification • International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) • American Spinal Injury Association (ASIA) • International Spinal Cord Society (ISCoS) • Most commonly used • International Classification for Surgery of the Hand in Tetraplegia (ICSHT) • For cervical level SCI only • Both classifications include a motor and sensory portion • The ICSHT is focused on the upper extremity
Who are the Stakeholders, and Why? • An increasing number of stakeholders • International Tetraplegia Group – Therapists and Surgeons • International Campaign for Cures of Spinal Cord Injury Paralysis (ICCP) • American Spinal Injury Association (ASIA) / International Spinal Cord Society (ISCoS) – UE Basic Data Set • Why? • Detect changes from natural recovery • Better define incomplete lesions • Measure the impact of interventions • Aimed at cure • Activity based therapy • Surgical reconstruction
Current ClassificationsA classification should tell you what to do. • ASIA, ISCOS, AIS, ISNCSCI • Work well with complete lesions, complicated - perhaps without predictive use for surgical treatment. Does not classify results or permit patient reported outcomes.
Current ClassificationsA classification should tell you what to do. • International Surgical Classification • Work well with complete motor paralysis, voluntary (C5,C6), Group 0,1,2,3, 1/3 of cases. • Many Patient choices, surgical variations in C7,C8 • Does not report anatomic change or PRO. Can be used for equivalency of function.

ICSHT (arms) Where do the Classifications Fail? Specific Examples • Group 0 – 4 • Group 1 – 3 • Group 2 – 5 • Group 5 – 3 • NC - 3 Subject Characteristics(n=9, 18 Arms*) ASIA (arms) C4 – 2 C5 – 5 C6 – 6 C7 – 3 NC - 2
Where do the Classifications Fail? • Incomplete Injuries • Spasticity • Characterizing Paralysis • Examples • 77VC R: C5, -C6, C7, C8 / 5, -6, -7, 8 • 99VC R: C6 / 0, -1, 2, -3, 4, 5, 6, -7 • 99 VC L: C6, -C7, C8 / 2, -3, -4, 5, 6, -7, 8
“IC Exceptions” • Partial Tetraplegia • Asymmetrical lesions • Recovered- • Regenerated, Repaired • Hyper-reflexive • Contracted • Bi-manual activities
Clinical Decision Support • Evidence Based Clinical Practice Guidelines • Appropriate Use Criteria • Cumulative experience without evidence • Informed Opinion
Clinical Practice Guidelines • Evidence based if outcome based. • Solve problems of clinical decision making. • Make Recommendations based on strong evidence. • Find directions for outcomes research. • Form the basis for national Performance Measures and Appropriate Use Criteria. • Search: www.guidelines.gov
Appropriate Use CriteriaRAND Methodology • Writing Group • Classification • Risk Adjustment • Important Clinical Criteria • Alternative Treatments
Appropriate Use Criteria • Review Group • Refine credibility of application by experts • Voting Group • Shareholders Rate for Appropriate, Maybe Appropriate, Rarely Appropriate

Measuring Spasticity • Challenges in measuring spasticity • Ashworth • Tardieu • Other • Distinguishing between measures of spasticity and spasms • Penn spasm scale, others>
Lets write a AUC about Surgical Decision Making in Tetraplegia. • Review the literature for outcomes summary. CPG unlikely. • Writing group • Review Group • Voting Group
