40 m Fast-paced Walk test
The purpose of the 40 m fast-paced walk test is to assess
short distance walking ability [29]. The test measures
the time, in seconds, taken to walk 40 m as quickly but
as safely as possible excluding turns. The total time is
expressed as m/s by dividing distance (40 m) by time
(seconds). Any gait aids required are recorded [48]. The
reliability and validity of the 40 m fast-paced walk test
has been tested in a group of combined pre-operative
THA and TKA patients, where test-retest reliability was
found to be excellent, ICC (2,1) = 0.91 (95 % CI = 0.81-0.97)
and responsiveness to initial surgery followed by recovery
was evident [38] Standard error of measurement (SEM)
was calculated as 1.73 (95 % CI = 1.39-2.29) and minimal
detectable change at the 90 % confidence level (MDC90)
was 4.04 sec [38].
