NCT01020435

Brief Summary

The investigators propose a prospective randomized 2 arm parallel observer-blinded phase II clinical study comparing a distinct method of upper cervical chiropractic manipulation to a sham technique in 50 individuals with stage I hypertension (systolic blood pressure (SBP): 140-159 mm Hg; diastolic blood pressure (DBP):90-99 mm Hg).

Outcome Measures

Primary Outcomes (1)

  • Unadjusted and Adjusted Changes From Baseline in Systolic and Diastolic Blood Pressure at Weeks 1, 3, 6

    To estimate the effect size and variability of change in systolic (SBP) and/or diastolic blood pressure (DBP) over a six week treatment period to use in planning a full-scale randomized controlled trial and to assess the believability of the placebo manipulation. The table shows the unadjusted and adjusted mean change in SBP and DBP from baseline to after Treatment 1 (Tx 1), 3 (Wk 3), and 6 (Wk 6) Weeks. Adjusted values were adjusted for age, sex, BMI, and respective baseline blood pressure. Wk 3 and Wk 6 DBP were also adjusted for stage of blood pressure (prehypertension or Stage 1 hypertension).

    Baseline after 1, 3, and 6 Weeks of treatment

Other Outcomes (2)

  • Number of Participants Who Were Recruited, Consented, Enrolled/Randomized, and Retained for the Duration of the Study

    19 months

  • Study Duration From Launch Date to Final Outcomes

    19 months

Study Arms (2)

Spinal Manipulation High Velocity

ACTIVE COMPARATOR

This non-rotary upper cervical procedure uses an impulse thrust with a controlled depth (high velocity). The participant's head is supported by a specially designed cushion and the doctor usually approaches the participant from in front of his or her head to contact soft tissue over the atlas transverse process, posterior to the lateral mass or occasionally on the C2 lamina or spinous process, with the pisiform process of one hand. The thrust is delivered by a contraction of the triceps muscles of both arms, which straightens the arms and applies the thrust to the participant.

Other: Spinal Manipulation

Sham Spinal Manipulation

PLACEBO COMPARATOR

The sham assessment procedures will be similar to the active group. It has been developed and validated by Vernon et al.

Other: Sham Spinal Manipulation

Interventions

The procedure in its broadest definition describes the application of a load (force or displacement) to specific body tissues (usually vertebral joints) with therapeutic intent. The mechanical characteristics of SM can vary in terms of its duration and amplitude, (hence, the rate at which it is applied), as well as its anatomical location, choice of levers, direction of force application, and the vehicle used to apply the force (manually or mechanically assisted).

Spinal Manipulation High Velocity

The sham assessment procedures will be the same as those in the high velocity treatment group. The sham intervention is identical to this treatment protocol except for the placement of the treating clinicians pisiform contact. The force and vector applied will be the same.
