Incidence (risk) of progression can be calculated according to the formula by Lonstein and Carlson (1984). According to the indication guidelines (Weiss et al. 2008) we have to distinguish between an-Indication for observation only (Incidence (risk) of progression-40%),-Indication for physiotherapy (Incidence (risk) of progression 40-60%),-indication for bracing (Incidence (risk) of progression 60% and more); The average patient from the majority of the papers on physical therapy found in Table 1 have no indication for treatment but for observation, only (blue spots).
