inter and intra rater reliability of the 10 meter walk test in the community dweller adults with spastic cerebral palsy

abstract objectives, the purpose of this research was to evaluate of the intra-rater and inter-raters reliability of the 10 meter walk test (10 mwt) in 30 adults with spastic cerebral palsy (cp) with subgroup analyses in gross motor function classification system (gmfcs). material & methods, participants  (19 men, 11 women; mean age 27 y and 9 mo) with gmfcs levels below iv (i, ii, and iii) non-randomly selected from the ra’ad rehabilitation goodwill complex . retest interval for inter-raters study lasted a week. during the tests, participants walked with their maximum speed. intraclass correlation coefficients (icc) estimated reliability . results the 10 mwt icc for intra-rater was 0.98 (95% confidence interval [ci] 0/96- 0/99) across participants, and >0/89 in gmfcs subgroups (95% confidence interval [ci] lower bound >0/67), the 10 mwt inter-raters’ icc was 0.998 (95% confidence interval [ci] 0/996-0/999), and >0/993 in gmfcs subgroups (95% confidence interval [ci] lower bound >0/977). standard error of the measurement (sem) values for both studies were small (0.02< sem<0.07). conclusion the conclusion is that excellent intra-rater and inter-raters reliability of the 10 mwt in adults with cp, specially in the moderate motor impairments (gmfcs level iii), indicates that this tool can be used in clinics to assess the results of interventions
