TI  - People at a persistent pain service can walk it, but some struggle to talk about 
      it: Reliability, detectable difference and clinically important difference of the 
      six-minute walk test.

AB  - OBJECTIVES: The six-minute walk test (6MWT) is a commonly used measure of 
      functional capacity. This study is the first to investigate the test-retest 
      reliability, minimal detectable difference (MDD) and the minimal clinically 
      important difference (MCID) for people attending a persistent pain service. 
      Relationships between change in 6MWT performance and change in self-reported 
      physical, functional and psychological outcome measures were also explored. 
      METHODS: A cross-sectional repeated measures design was used with people having 
      >9 months of pain attending an 8-week outpatient persistent pain programme. For 
      reliability and MDD, 27 people were recruited, for MCID calculations, 32 people 
      were recruited. The MCID was examined by dichotomising people into "improvers", 
      or "non-improvers" based upon the Global Rating of Change (GRC) in physical 
      abilities score. RESULTS: The mean (SD) 6MWT distance was 389.4 (93.6) m at 
      programme start, and 427.8 (83.0) m at week eight completion. The test-retest 
      reliability was good (intraclass correlation coefficient = 0.89) and the 
      MDD = 86.1 m. As there was no relationship between change in 6MWT distance and 
      GRC physical abilities at week eight (r = 0.132, p = 0.472) the MCID could not be 
      calculated. Furthermore, no relationships were found between change in 6MWT 
      distance and other self-reported measures. Changes in GRC physical abilities and 
      6MWT were frequently discordant, with increased 6MWT for 7/11 "GRC non-improvers" 
      and decreased 6MWT for 7/21 "GRC improvers". CONCLUSIONS: Amongst this cohort, 
      change in physical ability may or may not be reflected by self-reported change. 
      Objective tests of physical ability are recommended for people attending pain 
      services, and validated tests should align with intervention aims.
