Reliability and cross-cultural adaptation of the Turkish version of the Spinal Cord Injury Spasticity Evaluation Tool.

The Spinal Cord Injury Spasticity Evaluation Tool is a 7-day recall self-reported questionnaire that assesses the problematic and useful effects of spasticity on daily life in patients with spinal cord injury (SCI). We aimed to determine the reliability and cross-cultural validation of the Turkish translation of the Spinal Cord Injury Spasticity Evaluation Tool (SCI-SETT). After translation and back translation of the Spinal Cord Injury Spasticity Evaluation Tool, 66 patients between the ages of 18 and 88 years with SCI, American Spinal Injury Association impairment scale grades from A to D with spasticity, and at least 6 months after injury were assessed. Participants rated the SCI-SETT at the same time period of the day, 1 week apart, and test-retest agreement was investigated. Also, the Penn Spasm Frequency Scale, self-assessment of spasticity severity, self-assessment of spasticity impact, Functional Independence Measure motor subscale, and 36-Item Short Form Health Survey were assessed for the evaluation of the convergent validity. There were 45 participants with tetraplegia and 21 patients with paraplegia. The test-retest reliability for the SCI-SETT was good. The intraclass correlation coefficient was 0.80 at 95% confidence interval. There were no significant correlations between the SCI-SETT scores and Functional Independence Measure motor subscale and Penn Spasm Frequency Scale scores. There was a significant correlation between the SCI-SETT scores and vitality scores of the 36-Item Short Form Health Survey. The SCI-SETT showed statistically significant correlations with other measures including self-assessed spasticity severity and self-assessed spasticity impact (P<0.05). The SCI-SETT is a reliable self-rating tool for assessing spasticity in patients with SCI in the Turkish population.
