The Fox-walk test is a new method used to estimate aerobic capacity
outside a clinical environment, which may be useful in the implementation of
daily health-enhancing physical activity. The aim of our study was to investigate
the reliability of the test in people with rheumatoid arthritis (RA). METHOD:
Fifteen participants performed the Fox-walk test three times with weekly
intervals. The intraclass correlation coefficient (ICC), the standard error of
measurement (SEM) and the smallest detectable change (SDC) were used to estimate
the reliability. General health perception, lower limb pain and fatigue were
measured to determine their potential influence on the reliability. RESULTS:
There were no systematic differences between the three test occasions (p = 0.190)
and the reliability was almost perfect (ICC = 0.982). None of the covariates
influenced the reliability. The SEM was 0.999 ml/kg/min or 3.4% and the SDC was
2.769 ml/kg/min or 9.4%. CONCLUSIONS: These findings demonstrate that the
Fox-walk test is reliable in people with RA and enables differentiation between
people with RA and monitoring progress. The validity of the test among people
with RA is still to be determined. IMPLICATIONS FOR REHABILITATION: * The
Fox-walk test is a new method to estimate aerobic capacity and could be performed
walking or running. * The test is self administered without expensive equipment
and is available in 150 public places in Sweden and several other European
countries. * The Fox-walk test is a reliable test for use among people with
rheumatoid arthritis monitoring the progress of their physical activity.
