AB  - AIMS: To examine how the choice of words explaining ultrasound (US) may influence 
      the outcome of physiotherapy treatment for low back pain (LBP). METHODS: 
      Sixty-seven patients with LBP < 3 months were randomly allocated to one of three 
      groups - traditional education about US (control group [CG]), inflated education 
      about US (experimental group [EG]) or extra-inflated education about US 
      (extra-experimental group [EEG]). Each patient received the exact same 
      application of US that has shown clinical efficacy for LBP (1.5 Watts/cm(2) for 
      10 minutes at 1 Megahertz, pulsed 20% over a 20 cm(2) area), but received 
      different explanations (CG, EG or EEG). Before and immediately after US, 
      measurements of LBP and leg pain (numeric rating scale), lumbar flexion (distance 
      to floor) and straight leg raise (SLR) (inclinometer) were taken. Statistical 
      analysis consisted of mixed-factorial analyses of variance and chi-square 
      analyses to measure differences between the three groups, as well as meeting or 
      exceeding minimal detectable changes (MDCs) for pain, lumbar flexion and SLR. 
      RESULTS: Both EG and EEG groups showed a statistically significant improvement 
      for SLR (p < 0.0001), while the CG did not. The EEG group participants were 4.4 
      times (95% confidence interval: 1.1 to 17.5) more likely to improve beyond the 
      MDC than the CG. No significant differences were found between the groups for 
      LBP, leg pain or lumbar flexion. CONCLUSION: The choice of words when applying a 
      treatment in physiotherapy can alter the efficacy of the treatment.
