WORKSHEET (Supplemental to Lecture)


R.C.P. Minor

Purpose - Used to confirm the atlas laterality as the R.C.P. Minor is active on the opposing side.

Location - Found posterior to the Atlas (slightly above).

O.C. Superior

Purpose - Active during Atlas anteriority and laterality.

Location - Posterior to the t.p.s of Atlas.

First Branch Levator Scapula

Purpose - Tension is palpable upon Atlas laterality.

Location - Posterior and inferior to the Atlas t.p.s

S.C.M. - (Used only as muscle of confirmation)

Purpose - Working upon mastoid posteriority.

Location - The tip of the mastoid process and Inf.


Purpose - Active when Atlas t.p. is ant. (unless Axis is misaligned)

Location - Posterior t.p. of Atlas and slightly inferior.

C-1 through C-6 are palpated as the patient is lying supine and with his/her head resting on the Doctor's hands.  The patient's head should be slightly and passively elevated by the Doctor.  The patient's legs should also remain uncrossed.


R.C.P. Major

Purpose - Splints spinous deviation to the posterior right or left.

Location - Superior and lateral to the Axis spinous.

Second Branch Levator

Purpose - Working tension is involved with Axis rotation as the t.p. misaligns anterior.

Location - Inferior and slightly posterior to the t.p.s of Axis.

First Branch Scalenus Medius

Purpose - used to distinguish the posterior rotation of the Axis transverse process.

Location - Inferior and slightly anterior to the t.p.s of Axis.

C3 - T12


Purpose - Active during the misalignment on the side opposite spinous rotation.

Location - Lateral to the spinous process, running oblique and inferior to the transvere processes of a vertabra below.

Intertransversari - (when present and palpable)

Purpose - Working upon the inferior t.p. from above and the superior t.p. from below.

Location - Between the transverse processes.

Pelvis and Sacrum

Gluteus Maximus

Purpose - Active when thee sacrum is misaligned; upon the opposite side of apex deviation.

Location - Inferior and lateral to the apex of Sacrum.

Posterior Sacro-Illiac Ligament

Palpation - tightened when the Sacral base misaligns anterior or the Illium misaligns posterior.

Location - Medial to the posterior superior spines of the Illia.

Erector Spinae

Purpose - Used to distinguish the inferior position of the misaligned Sacrum or Illium.

Location - Superior to the base of the Sacrum and crest of the Illium.


Purpose - Active upon posterior misalignment of the Sacrum.

Location - Lateral to the 3rd and 4th Sacral segments.

Gluteus Medius and Gluteus Minimus

Purpose - Working tension is involved to splint the Illium as it moves anterior upon misalignment.

Location - Lateral to posterior superior spines of the Illia.
