Study to Demonstrate That Muscle Pattern Recognition (MPR) is an Effective Evaluation Tool for Musculoskeletal Neck or Back Pain

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.

The investigators hypothesize that non able-bodied participants with reported acute, sub-acute, or chronic symptoms of neck or back pain of a musculoskeletal origin will have magnetic resonance imaging (MRI), X-ray and blood parameters that do not demonstrate a statistical difference between “normal” (able-bodied) volunteers.

Muscle pattern recognition (MPR) testing will show statistically different results between these groups. This statistically significant finding in MPR results will enhance a clinician’s determination of clinical normality or abnormality.

If this hypothesis is demonstrated, the MPR modality will be the first quantitative tool developed for assisting in the diagnosis of the presence or absence of a musculoskeletal dysfunction in a patient population. The availability of such an evaluation tool to a healthcare provider for patients with soft tissue, non-surgical neck or back complaints will substantially improve the accuracy of diagnosis and case management decisions.

Primary Outcome Measures:
  • This study will demonstrate differences in muscle recruitment patterns between individuals who are “normal” (asymptomatic, able-bodied) from those individuals (“not normal”) with underlying biomechanical dysfunction of the neck and back

  Show Detailed Description


Ages Eligible for Study:   18 Years to 62 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

Individuals may participate in this study if they meet the following criteria:

  • 18-62 years of age; male or female.
  • 4 foot 10 inches to 6 foot 5 inches in height
  • No prior back or neck surgery, or structural deformity of the spine
  • No orthopedic injury/illness/surgery limiting range of motion of the shoulders
  • No ongoing treatments for back or neck pain/injury from a health professional in the last two years.
  • No prior loss of work time due to a neck or back injury/illness
  • Laboratory studies: complete blood count (CBC); sedimentation rate; creatinine phosphokinase (CPK); calcium; phosphorus; pregnancy test if female; and drug screen. Laboratory studies will be examined by a physician investigator to determine if the findings will exclude the participant from participating successfully in study activities. A positive pregnancy test or drug screen will automatically exclude the participant from the study.
  • Clinical examination of the neck and back by two physicians in agreement that the participant may participate in the study.
  • Absence of congenital or acquired neuromuscular disease or dysfunction

Exclusion Criteria:

Individuals may not participate in this study if they meet the following criteria:

  • Claustrophobia or anxiety associated with being enclosed in narrow spaces
  • Muscle weakness or sensory feedback abnormalities that affect(s) gait
  • Pregnancy
  • Concurrent serious medical illness such as cancer; recent heart attack or stroke; heart rhythm disturbance requiring a pacemaker; diabetes that causes pain; numbness; or decreased circulation in the legs.
  • Alcohol or illicit drug abuse.
  • History of (or concurrent) psychiatric illness necessitating ongoing “talk” therapy and/or psychotropic medications
  • History of back or neck pain lasting more than 3 days or requiring time off of work AND healthcare provider treatments within the last 2 years
  • Involved in a lawsuit or receiving worker’s compensation or disability payments
  • Individuals with pacemakers or pacemaker wires; aneurysm clips; or metallic foreign bodies or metal shavings in the body.
