Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The participants will attend two intervention sessions in random order. The experimental intervention will be a single session of chiropractic care. Full spine adjustments will be carried out during the experimental session. The entire spine and sacroiliac joints will be assessed for vertebral subluxations and adjusted where deemed necessary by a registered chiropractor. The intervention will take approximately 10 minutes to carry out. There will be a 1 week washout period between the 2 interventions.
Intervention code [1] 312162 0
Treatment: Other
Comparator / control treatment
The control intervention will consist of passive and active movements of the subject’s head, spine and body that will be carried out by the same chiropractor who pre-checks the participants for vertebral subluxations and who performs the adjustments in the experimental intervention session. This control intervention will involve the participants being moved into the adjustment setup positions where the chiropractor would normally apply a thrust to the spine to achieve the adjustments. However, the experimenter will be particularly careful not to put pressure on any individual spinal segments. Loading a joint, as is done prior to spinal adjustments has been shown to alter paraspinal proprioceptive firing in anesthetised cats (Pickar & Wheeler, 2001), and will therefore be carefully avoided by ending the movement prior to end range- of-motion when passively moving the participants. No spinal adjustments will be performed during any control intervention. This control intervention is not intended to act as a sham adjustment but to
act as a physiological control for possible changes occurring due to the cutaneous, muscular or vestibular input that will occur with the type of passive and active movements involved in preparing a patient for an adjustment. It also acts as a control for the effects of the stimulation necessary to collect the dependent measures of the study, and acts as a control for the time required to carry out the adjustment intervention. The control intervention will take approximately 10 minutes to complete.

Key exclusion criteria
Subjects were ineligible to participate if they exhibit no evidence of vertebral subluxations, have absolute contraindications to spinal adjustments, had experienced previous significant adverse reactions to chiropractic care, or they are suffering from a current upper or lower limb disorder/dysfunction that would make them unable to carry out data recording sessions (e.g. sprain/strain/fracture).
