For upper cervical chiropractic care in Encinitas, David Shores DC applies the Knee Chest technique from his Saxony Road office in the New Encinitas corridor east of Interstate 5. Upper cervical work isolates the atlas-axis junction using precise low-force corrections without spinal rotation or cracking, an integrative neurological focus that aligns with the functional-medicine model at Nature & Science Medicine. His practice concentrates on chronic conditions where standard medical treatment has plateaued, including migraine disorders, TMJ dysfunction, and multi-year cervicogenic pain syndromes. Pre-adjustment assessment involves digital motion-study radiography to measure atlas misalignment vectors down to sub-degree specificity before any manual correction. Complex cases involving overlapping spinal and systemic complaints are co-managed with primary care providers such as Kind Health Group to coordinate imaging and pharmaceutical taper protocols. Highest-tier cases involve post-concussive craniocervical instability evaluation with flexion-extension radiographic series to rule out ligamentous laxity before initiating upper cervical correction sequences.
