Abstract

Study design: Cross-sectional study. Objectives: To assess the interrater reliability and validity of the test-table-test (TTT) with which paralympic sports participants involved in Nordic sit-ski sports may be classified. Setting: Movement laboratory in a rehabilitation centre, The Netherlands. Methods: Thirty-three persons with a spinal cord injury caudally to Th2, a leg amputation, poliomyelitis affecting the trunk and/or lower extremities, or cerebral palsy participated. Subjects were classified according to a classification system for Nordic skiing (that is, five subclasses between LW10 and LW12) by two raters, involving, among others, a combination of four balance tests called TTT. The validity of the TTT was investigated using a gold standard, involving balance perturbation tests on a force plate and centre of pressure (CoP) displacement measurements. Results: As for the interrater reliability, Spearman's rank-correlation coefficient was 0.95 (P
