On balance of the limited evidence , the 40 m self-paced test was the best rated walk test , the 30 s-chair st and test and timed up and go test were the best rated sit to st and tests , and the Stratford battery , Physical Activity Restrictions and Functional Assessment System were the best rated multi-activity measures .

The reliability, validity and responsiveness of an aggregated locomotor function (ALF) score in patients with osteoarthritis of the knee.
OBJECTIVES The aggregated locomotor function ( ALF ) score , a simple measure of observed locomotor function , using timed walking , stairs and transfers , was developed and evaluated for intra-tester reliability , criterion-related validity and responsiveness in a sample of patients with knee osteoarthritis . METHODS Patients with knee osteoarthritis ( n = 214 ) were recruited for inclusion in a r and omized controlled trial investigating two methods of exercise provision . Before treatment , patients completed the Western Ontario and McMaster Universities Osteoarthritis Index ( WOMAC ) and Short Form 36 health survey ( SF-36 ) question naires and were timed whilst performing an 8 m walk , ascending and descending a set of gymnasium stairs and completing a test of transferring in and out of a chair . A group of 15 patients also undertook a replicate test-retest reliability study of the above outcome measures . St and ardized response means were calculated for the ALF , WOMAC and SF-36 from data from the clinical trial . RESULTS The ALF takes 10 min to administer and demonstrated excellent intra-tester reliability , with excellent intra-class correlation coefficient ( ICC ) statistics ( ICC(2,k ) 0.99 ; 95 % CI 0.98 - 0.99 ) , and low st and ard error of measurement ( 0.86 s ) and smallest detectable difference ( 9.5 % ) values . Criterion-related validity with the physical function dimensions of the WOMAC and SF-36 was good , with correlation coefficients of 0.59 and - 0.53 respectively . St and ardized response means were higher for the ALF ( 0.49 ) than for both the WOMAC ( 0.39 ) and the SF-36 ( 0.12 ) . CONCLUSIONS This work has demonstrated that the ALF can be used as a measure of physical function status and as a means of quantifying treatment response . The measure offers a simple and convenient outcome in the assessment and treatment of locomotor dysfunction . The ALF score is a reliable , valid and responsive outcome measure over 12 months and can be recommended for use in the evaluation of patients with knee osteoarthritis
