 Diagnosis

  • Position:  FSrightRleft
  • Motion Restriction:  Backward-bending, left side-bending, right rotation.

Treatment

Patient is supine on the table with the operator sitting or standing at the head.

Operator’s left hand controls the patient’s occiput with the web of the thumb and the index finger along the soft tissues at the cervicocranial junction.OAflex2

 

 

Operator’s right hand holds the patient’s chin with the index finger in front and the middle finger below the tip of the ramus and with the right forearm in OAflex3contact with the right side of the patients head.

 

 

The backward-bending barrier is engaged by the operator’s hands rotating the head posteriorly around a transverse axis through the external auditory meatus.OAflex4

 

 

 

Left side-bending is introduced through the operator’s right forearm by slight left-to-right translation. (Rotation is not actively introduced)OAflex5

 

 

The patient is instructed to look down at the feet or pull the chin toward the chest against resistance offered by the operator’s right hand for a 3-5 second light isometric muscle contraction.

After relaxation, the new backward-bending, left side-bending , and right rotational barriers are engaged.

Operator’s muscle contraction is repeated 3-5 times with the operator relocalizing against the resisted barrier after each effort.

Occipitoatlantal (C0-C1) Flexion Restriction

by

Patient is supine on the table with the operator sitting at the head of the table.

Operator’s hands grasp the sides of the patient’s head with the lateral aspect of the index
fingers monitoring along the posterior arch of the atlas and the rest of each hand controlling the head.

Operator forward bends the patient’s head by anterior rotation around an axis of rotation OASupFR3through the external auditory meatus while monitoring for the first movement of the atlas.

 

 

Using the hands, the operator introduces translation from right to left sensing for resistance to movement at his index fingers.  If resistance is felt, the motion restriction is OASupER4to forward bending, right side-bending, and left rotation (ESleftRright).  Something interfered with the left condyle’s ability to glide posteriorly.
