Certain postures, and particularly abnormalities in posture like those described above, can provide invaluable information about muscle tightness, muscle imbalances and potential injury and performance issues as noted earlier. For example, if we are performing a visual examination of a college baseball pitcher, we may notice some deviations commonly seen in pitchers. This would include but is not limited to: scapular protraction and depression, scapular winging, thoracic and lumbar scoliosis, pelvic asymmetry, hip adduction, genu valgum and foot pronation. For the college pitcher, this can be the result of years and years of participation in a sport that requires an asymmetrical or one-sided position. If this asymmetry is not addressed with training both during the season and after, tightness and weakness can result that can lead to injury and decrease performance. Let’s look at a few postural deviations more closely, reviewing the likely causes, potential injuries that can occur, and a few of the performance issues that can arise:
This can be the result of tightness of the anterior structures (pectorals, etc.) and weakness of the posterior structures (rhomboids, etc).
