Blood samples in test-tubes

An article in the Journal of Orthopaedic & Sports Physical Therapy April 2014 indicates that spinal manipulation causes an increase in neurotensin, oxytocin, and cortisol immediately after the adjustment.

The study took 30 asymptomatic volunteers and put them into lumber, thoracic, and cervical manipulation groups.

Each group had blood drawn before, immediately after, and then 2 hour after a spinal adjustment.

The neurotensin and oxytocin were increased in all three groups, and the cortisol was increased with cervical manipulation. So what does this mean?
