Kalsi-Ryan, Sukhvinder; Beaton, Dorcas; Curt, Armin; Popovic, Milos R; Verrier, Mary C; Fehlings, Michael G (2014). Outcome of the upper limb in cervical spinal cord injury: Profiles of recovery and insights for clinical studies. Journal of Spinal Cord Medicine, 37(5):503-510.

Abstract

Background Improved appreciation of recovery profiles of sensory and motor function as well as complex motor functions (prehension) after cervical spinal cord injury (SCI) will be essential to inform clinical studies to consider primary and secondary outcome measures for interventions and the optimization of dosing and timing of therapies in acute and chronic SCI. Objectives (1) To define the sensory, motor, and prehension recovery profiles of the upper limb and hand in acute cervical SCI and (2) to confirm the impact of AIS severity and conversion on upper limb sensorimotor recovery. Methods An observational longitudinal cohort study consisting of serial testing of 53 patients with acute cervical SCI was conducted. International Standards of Neurological Classification of Spinal Cord Injury, Graded Redefined Assessment of Strength Sensibility and Prehension (GRASSP), Capabilities of Upper Extremity (CUE-Q) Questionnaire, and Spinal Cord Independence Measure III (SCIM-III) were administered at 0-10 days, 1, 3, 6, and 12 months. Analysis Change over time was plotted using mean and standard deviation of the total and subgroups of the sample. Results Individuals with traumatic tetraplegia show distinct patterns of recovery. Factors that distinguish homogeneous subgroups of the sample are: severity of injury (level of injury, completeness) at baseline and conversion from a complete to an incomplete injury. Conclusions In cervical SCI, clinical recovery can be assessed using standardized measures that distinguish levels of activity and impairment. Specific recovery profiles of the upper limb over the 1-year timecourse provide new insights and opportunity for combined analysis of recovery profiles for different clinical assessment tools of upper limb function which are meaningful to inform the design of study protocols.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
