Motor capability and performance in children with physical disability and children with typical development

Abstract

eS621 procedures and to investigate the reliability of the movement control tests in patients with lumbar spine disorders. Purpose: To determine the intra-rater reliability of a battery of movement control tests in patients with lumbar spine disorders. Methods:Activelumbarflexioncontroltestsconsistingof 7 items with the maximum score of 69 points and active lumbar extension movement control tests consisting of 7 items with the maximum score of 71 points were examined in this study. Ten patients with chronic non-specific LBP (6 males and 4 females, mean age=43.8 years, SD=15.6) who were classified into the flexion-typed LBP were tested with the active lumbar flexion control test battery, and 5 patients with LBP (1 male, 4 females, mean age=44.6 years, SD=17.3) who were classified into extension-typed LBP were tested with the active lumbar extension control test battery. We videotaped the whole process of testing. One trained physical therapist watched these videos and rated each test in two different days with one-week apart. The score of each testing battery was transformed into percentile score in order to assess the intra-rater reliability of these tests by using intraclass correlation coefficient (ICC). Results: Both active lumbar flexion control tests and active lumbar extension control tests demonstrated acceptable to good test-retest reliabilities (ICCs: 0.75 and 0.79 respectively) and internal consistency (Cronbach alpha coefficients: 0.86 and 0.88 respectively). Conclusion(s): A trained physical therapist can reliably rate both active lumbar flexion movement control tests and active lumbar extension control tests.
