The placebo postural correction procedure did not produce a significant change in the static position of the scapula, or on the range of painfree shoulder flexion and abduction in the plane of the scapula in the symptomatic subjects.
With the exception of a significantly smaller lateral linear displacement of the scapula from the thoracic spine (–0.3 cm, P = .001), the placebo procedure did not produce a significant effect on any of the measurements of interest in the asymptomatic group.
However, the clinical importance of the reduced lateral linear displacement of 3 mm is questionable.
