Investigating the Clinical Effects of Supporting Neutral Pelvic Position in Sitting

Inclusion Criteria

• •1. Individuals with a history of 1 or more episodes of low back pain (LBP) in the last calendar year or who currently has LBP without radiation of pain from the low back into the legs.
• •2. Males or Females who are 20-65 years of age.
• •3. Individuals who engage in work that requires sitting at a desk or computer 25 or more hours a week.
• •4. Individuals who plan to work full time for each of the 3 weeks of the trial (April. 22 - May. 14, 2015), with no planned business travel or time off.
• •5. Individuals who can commit to attending two 1-1.5 hours data collection events (appointments times from 4:30-8:30 pm): Either on: Wed. April 22, 2015 and Wed May 13, 2015 or Thurs. April 23, 2015 and Thurs. May 14, 2015 at a location on the west side of Ann Arbor, MI.
• •6. Individuals who can read, write and understand English fluently. (Questionnaires are in English)
• •7. Individuals who, while maintaining upright sitting, can lift their knee approximately 3-6 inches off the chair (as in marching), one at a time, on both sides.
• •8. Individuals who are willing to wear non-binding or flexible clothing around their hips and pelvis at work during the three weeks of the trial if chosen to be in the experimental group. Note: Because the posture device being studied tilts the user's pelvis more upright, compared to the common slump / backward pelvic tilt that occurs in sitting, some find, especially males , that this binds them in the front of their pelvis and groin area when their clothing is tight or restrictive. Looser or flexible clothing has significantly aided in tolerance of this positioning and will be recommended if subject is chosen to be in the experimental group, assigned to use the device.
