TI  - Within-Session Test-Retest Reliability of Pressure Pain Threshold and Mechanical 
      Temporal Summation in Chronic Low Back Pain.

AB  - OBJECTIVES: To determine the absolute and relative within-session test-retest 
      reliability of pressure pain threshold (PPT) and temporal summation of pain (TSP) 
      at the low back and the forearm in individuals with chronic low back pain (CLBP) 
      and to test the impact of different sequences of measurements on reliability 
      metrics. MATERIALS AND METHODS: Twenty-eight adults with CLBP were recruited. 
      Relative (intraclass correlation coefficient [ICC] and coefficient of variation) 
      and absolute reliability (standard error of measurement and minimal detectable 
      changes) were quantified at 4 sites (back: sacrum and lumbar erector spinae; 
      wrist: hand dorsum and wrist flexors) for PPT and 2 sites (hand and low back) for 
      TSP, for various sequences of measurements. RESULTS: Systematic differences were 
      found between within test and retest for most PPT sequences at the lumbar erector 
      spinae site and 1 TSP sequence (1-2-3) at back and hand sites, precluding 
      reliability analyses for these data. Within-session PPT relative reliability was 
      excellent at low back (ICC = 0.83 to 0.94) and wrist (ICC = 0.88 to 0.97) sites, 
      whereas TSP showed good to excellent reliability at hand (ICC = 0.80 to 0.90) and 
      low back (ICC = 0.73 to 0.89). In general, 2 and 3 measurements optimized 
      absolute and relative reliability for TSP and PPT, respectively. DISCUSSION: 
      Within-session reliability was generally excellent for PPT and TSP at the low 
      back and hand sites among individuals with CLBP. We recommend using 3 
      measurements for PPT and 2 for TSP to optimize reliability. Caution is 
      recommended when testing PPT of the painful lower back area since a systematic 
      difference was present between the test and retest.
