Study Notes

HVLA Techniques and Considerations

Use high-velocity low-amplitude (HVLA) with greater precision and caution in sensitive situations.
Oral contraceptives have a 9% risk associated with non-dissection vascular events.
Recent infection is the least associated factor with dissection events compared to migraines, smoking, or family history of stroke.
Visual disturbances should alert practitioners to a potential dissection event in patients.
In pregnancy or sensitive cases, activator tools are preferred over traditional HVLA techniques.

Risk Factors and Contraindications

Recent trauma is a common risk factor for both dissection and non-dissection vascular events.
In pregnant patients, HVLA should be performed only on the thoracic spine, avoiding strain to the abdomen.
Increased muscle tone is vital for assessing the appropriateness of HVLA.
Cervical HVLA manipulation is contraindicated in cases of rheumatoid arthritis but can be considered for mild osteoarthritis.
Cerebral blood flow is not significantly affected by cervical side-bending during manipulation.

Screening and Assessment Techniques

Maigne’s test screens for vertebrobasilar insufficiency and is no longer supported for pre-manipulative screening in cervical HVLA.
Sudden severe headache is a key sign of cervical arterial dysfunction (CAD) to watch for in practice.
Cervical HVLA should be avoided in transverse and linear techniques to ensure patient safety.

Specific Techniques for Joint Manipulation

For AA joint HVLA, the support hand should be on the occiput and upper cervical spine for stabilization.
The practitioner should be positioned on the side of the bed with elbows in while performing AA joint HVLA.
Use a linear thrust over the cervical spine to induce C1 rotation.
In posterior glide OA HVLA, direct thrust towards the anterior occipital condyle; for anterior glide, the contact point should be medial to the occipital condyle.
The thrust in anterior glide OA HVLA is primarily executed by the contact hand.

Patient Management and Cervical Structures

During AA joint HVLA, maintaining a lower table height accommodates a more transverse thrust vector.
The Occipito-Atlantal (OA) joint contributes 50% of cervical spine movement when the chin is brought to the chest.
Avoid the vertebral artery during HVLA techniques to prevent vertebrobasilar insufficiency (VBI).

Pain Processing and Initial Management

The Trigemino-Cervical Nucleus processes nociceptive input primarily from the head and upper neck.
For acute cervical facet sprain, address soft tissue guarding before considering joint mobilization.
The anterior longitudinal ligament does not directly contribute to the Circle of Willis.

Associated Conditions and Significance

Whiplash Associated Disorder (WAD) is commonly associated with a history of motor vehicle accidents.
The Rectus capitis posterior minor plays a significant role in cervical HVLA techniques, enhancing effectiveness and safety.
