PALPATION EXAMINATION OF THE POSTERIOR CERVICAL SPINE: THE IDEAL, AVERAGE AND ABNORMAL The two purposes of this paper relate to Man in or GEOFFREY D MA1TLAND beyond his fifth decade The first purpose is to detail the 'abnormalities' which can be found by palpation Geoffrey Maryland, MB.E, A.U A., F.CS.P, FA.CP, S.A SP,MM T.A.A , is well-known for his study, writing examination of the cervical spine posteriorly, and the and teaching of manipulative therapy in the post-graduate second is to try to explain what the findings indicate. area, he is also a private practitioner in North Adelaide. The 'Ideal' spine, the 'Abnormal' spine and three groups of the 'Average' spine are defined. The method of examining the cervical spine by Tins paper was presented at the 2nd National Congress of the M T A A, Adelaide, South Australia, November, 1980 palpation techniques is detailed. Discussion centres around what is normal for an ideal spine and the average spine and what it is that changes when the average spine becomes 'abnormal'. The associated 'new' and 'old' tissue changes are discussed in relation to the common findings in the Upper, Middle and Lower Cervical Spine. Palpation examination of the posterior from the skull to the third cervical Average elements is the most informative single vertebra, The 'Average' spine is not TdeaF. It does section of physical examination of the • the middle cervical spine (C3-C5), being not consist of a series of ideal motor cervical spine (excluding examination for from the third vertebra to the fifth, and serious disorders of the Central Nervous • the lower cervical spine (C5-C7), being Syitim, the Penpheral Nervous System from the fifth to the seventh cervical and the Vascular System).

Examination by palpation 'Average' spine and the 'Abnormal'spine techniques, on the other hand, is always informative. This paper is related to Man in his fifth The Ideal, Average and decade and beyond, and has two Abnormal Spine purposes The first purpose is to detail the abnormalities which may be found by Ideal palpation examination of the cervical The ideal1 spine refers to a series of spine posteriorly, and the second is to try intervertebral motor segments (te to explain what the findings might interbody and zygapophyseal joints with indicate.
