Outcome Measures

Primary Outcomes (2)

  • Participant blinding

    The blinding index is scaled to an internal of -1 to +1, +1 being complete lack of blinding, 0 being consistent with perfect blinding, -1 indicating opposite guessing which may be related to unblinding.

    Immediately after intervention

  • Participant blinding

    The blinding index is scaled to an internal of -1 to +1, +1 being complete lack of blinding, 0 being consistent with perfect blinding, -1 indicating opposite guessing which may be related to unblinding.

    48 hours after intervention

Study Arms (2)

Genuine/real

EXPERIMENTAL

15 participants receiving genuine/real chiropractic adjustment

Procedure: Chiropractic adjustment

Simulated/sham

SHAM COMPARATOR

15 participants receiving simulated/sham "adjustment"

Procedure: Sham adjustment

Interventions

A single-session of genuine/real high-velocity, low-amplitude (HVLA) manual chiropractic adjustments to various regions of the spine (i.e., cervical, thoracic, lumbo-pelvic)

Genuine/real

A single-session of simulated/sham high-velocity, low-amplitude (HVLA) manual chiropractic adjustments to various regions of the spine (i.e., cervical, thoracic, lumbo-pelvic)
