Three-dimensional spinal coupling mechanics: Part I. A review of the literature.

摘要: OBJECTIVE To determine the state of knowledge relative to three-dimensional spinal coupled motion and check validity currently accepted two-dimensional coupling as taught in chiropractic. DATA COLLECTION A hand search available reference texts a computer literature from Index Medicus were collected with an emphasis on studies human movements. RESULTS Most postural movements result complicated six degrees freedom. Previous results based upon radiographic are inadequate inaccurate. It is important that chiropractic colleges techniques use kinematics update their curricula advance treatment procedures. CONCLUSION Full investigations patterns have shown vertebrae rotate translate all three axes previous theories inaccurate invalid. Postural rotations translations, which main motions studied research, altered configurations normal sagittal plane curves cause both abnormal dimensions. Chiropractic letter listings (such PRS, ASRP, etc.) outdated, incomplete, invalid representations segmental Mechanical loading neuromusculoskeletal tissues plays vital role position, dynamics, proper growth, repair symptoms. Future should study translations skull thorax for associated Combined along curvatures need be characteristics well.
