AB  - The development and the validation of the Pavia Physical Performance Scale (PPPS) 
      is here presented. PPPS is a new instrument evaluating the physical performance 
      of pacemaker implanted patients. Data comes from a cross-over clinical trial on 
      the efficacy of two functions of the pacemaker device. Primary end-point is the 
      improvement of the physical performance together with the quality of life. We 
      used data of 168 patients actually enrolled and interviewed with the Pavia 
      Physical Performance Scale. We first selected 30 Likert-type items; then we 
      applied a statistical methodology of Homogeneity Analysis (HOMALS). We verified 
      the homogeneity of the scale and the internal consistency (Cronbach's alpha = 
      0.92). With the same methodology, we developed the final version of PPPS. The 
      final version lists 20 items; based on the results of the psychometric analysis, 
      we turned the Likert-type scoring into a binary scoring (1 = no limitation of 
      physical activity, 0 = limitation or never tried). The external validity, trough 
      an Analysis of Variance of PPPS mean scores within New York Heart Association 
      classes (NYHA), has been performed. We found a negative linear trend of PPPS 
      scores and NYHA classes. That means an association between high PPPS scores (good 
      physical performance) and low NYHA classes (also good physical capacity). The 
      Pavia Physical Performance Scale (PPPS) could be proposed as a valid and 
      consistent scale aimed to evaluate physical performance in pacemaker implanted 
      patients. We suggest to use it in the clinical practice in addition to more 
      traditional techniques.
