Janda identifi ed three basic compensatory patterns (65). It is not to say that other compensations do not occur. He simply suggested that there was a cascading effect of alterations or deviations in static posture that would more likely than not present themselves in a particular pattern. The three postural distortion patterns to be assessed during a static postural assessment include the pronation distortion syndrome, the lower crossed syndrome, and the upper crossed syndrome.Pronation distortion syndrome: a postural distortion syndrome characterized by foot

pronation (fl at feet) and adducted and internally rotated knees (knock knees) (see Figure 6.20 and Table 6.9).Lower crossed syndrome: a postural distortion syndrome characterized by an anterior
■
tilt to the pelvis (arched lower back) (see Figure 6.21 and Table 6.10).Upper crossed syndrome: a postural distortion syndrome characterized by a forward
■
head and rounded shoulders (see Figure 6.22 and Table 6.11).
