Sex

Inclusion Criteria

  • •oIndividuals will be required to have completed the letter of informed consent (Appendix E) and sign the letter of information (Appendix E) in order to participate in this study.
  • •oParticipants between the ages of 18-45 years will be required for this study. Subjects older than 45 years will not be able to participate in the study as Ding (2005) found evidence that knee cartilage defects were far more common in subjects over 45 years of age than those that are younger.
  • •oParticipants must be older than 18 years old to avoid having to obtain parental permission.
  • •oEach participant must present with at least one fixation in the relevant levels (L2-L5) of the lumbar spine as the purpose of the study is to investigate the effects of a lumbar spine manipulation on the muscle activity and joint position sense of the lower limb. Motion palpation of the lumbar spine will be used to determine if there is a fixation in these areas (Bergmann and Peterson 2010).
  • •Symptomatic Participants
  • •oLow back pain for a duration of three or more months.
  • •oDiagnosis of low back pain must be of a mechanical origin.
  • •Asymptomatic Participants
  • •No history of low back pain or no lower back pain three weeks prior to the study

Exclusion Criteria

  • •oThe eligible participant must not have been adjusted 4 weeks prior to their visit to participate in the study as this may allow for possible effects of previous treatment to alter the outcome of the readings and results
  • •oParticipants that do not present with fixations in the relevant spinal levels (L2-L5).
  • •oIndividuals who present with hip, knee, or ankle pain as a result of trauma or surgery (Hurley, Jones and Newham 1994; Hurley 2003).
  • •oParticipants that have primary or secondary disorders that may compromise normal neurological function (Diabetes Mellitus) (Eliassen 1964) as this may alter results in the study.
  • •oParticipants who are taking medication that may affect muscle activity (i.e. sedatives and stimulants) (Kruk 2014).
  • •oParticipants that have a Body Mass Index (BMI) of 30 or greater as this may affect surface EMG readings (Nordander et al. 2003).
  • •oParticipants will not be a part of the study if they have any contraindications to spinal manipulative therapy (SMT) based on a case history and physical exam (Bergmann and Peterson 2010). This may include, but are not limited to the following:
  • •Neurological conditions (cauda equine syndrome, neuropathies)
  • •Malignancy (tumour)
  • •Vascular (aortic aneurysm, atherosclerosis)
  • •Infections (osteomyelitis)
  • •Skeletal conditions (osteoporosis, osteoarthritis, fractures)
  • •Symptomatic Participants
  • •oParticipants who present with low back pain due to trauma or structural anomalies.
  • •oLow back pain with neurological deficits (muscle weakness, reflex changes) and radiation into the legs.
  • •oPrevious back surgery
  • •oSpinal tumours or infections.
