Considerations & references

  1. A 1-min walk test is a reliable method od assessing finction in children with ambulatory CP and shows a significant correlation with the GMFM - Validity of a 1 minute walk test for children with cerebral palsy (McDowell et al, 20007)
  2. A 1-min walk test is a reliable method of assessing function in children with CP but care must be taken when interpreting changes in individual patient data. Test-retest reliability of a 1-min walk test in children with bilateral spastic cerebral palsy (BSCP) (McDowell et al, 2009)
