The research Dr Haavik is involved in explores the effects of chiropractic care. In particular she investigates what happens in the brain when a chiropractor adjusts dysfunctional spinal segments.

She has utilised sophisticated neuroscience techniques such as somatosensory evoked electroencephalography and transcranial magnetic brain stimulation to investigate the effects of chiropractic adjustments of vertebral subluxations on somatosensory processing, sensorimotor integration and motor cortical output.

Recently she has translated this science into everyday language into her best selling book, The Reality Check.
