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
NEW Version 2/2013
ASIA Update – Non Key Muscles
Movement Root LevelShoulder: Flexion, extension, abduction, internal and external rotationElbow: Supination
C5
Elbow: PronationWrist: Flexion
C6
Finger: Flexion at proximal joint, extensionThumb: Flexion, extension and abduction in plane of thumb
C7
Finger: Flexion at MP jointThumb: Opposition, adduction and abduction perpendicular to palm
C8
Finger: Abduction of the index finger T1
Congruence with ICSHT?Movement Root

Finger: Abduction of the index finger T1
Current ClassificationsA classification should tell you what to do.
ASIA, ISCOS, AIS, ISNCSCIWork 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 ClassificationWork 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.
