Cohort Studies

Back Clinic Cohort Studies. Cohort studies is a study design where one or more people (called cohorts) are followed and subsequent status evaluations with respect to a disease or outcome are conducted to determine which participants’ exposure characteristics (risk factors) are associated. As the study is conducted, the outcome from participants in each cohort is measured and relationships with specific characteristics determined. Cohort studies usually observe large groups of individuals and record their exposure to certain risk factors to find clues as to the possible causes of disease. They can be prospective studies that gather data going forward, or retrospective cohort studies, which look at data already collected. This type of research can also help identify social factors that influence health.

The fundamentals of a cohort study are:

a. Identify people who are free of disease at the beginning of study
b. Assemble cohorts of exposed and unexposed individuals
c. Follow cohorts for the development of incident outcomes
d. Compare the risks of incident outcomes in each cohort


  1. Cheaper & easier than a randomized controlled trial (RCT)
  2. Standardization of criteria/outcome is possible
  3. Subjects can be matched, which limits the influence of confounding variables


  1. Cohorts can be difficult to identify from confounding variables
  2. No randomization, which means that imbalances could exist
  3. Blinding/Masking is difficult
  4. The outcome of interest can take a long time to occur

A herniated disc is typically a very painful condition, especially if the inner gel-like substance of the intervertebral disc, known as the nucleus pulposus, pushes through the thick, outer ring of cartilage and puts pressure on the sensitive nerves of the spine. Discs are soft, rubbery pads found between each vertebrae of the spine that act as shock-absorbers, allowing the spine to bend and/or flex. An intervertebral disc may begin to rupture as a result of wear-and-tear or due to a sudden injury. Fortunately, most individuals who’ve suffered a herniated disc can find relief from a variety of non-operative treatments before considering surgery. The following article highlights the impact of early treatment for herniated discs in the lumbar spine, or low back.

Migraine Pain & Lumbar Herniated Disc Treatment in El Paso, TX

Migraine Pain & Lumbar Herniated Disc Treatment in El Paso, TX

One of the most prevalent causes of lower back pain and sciatica may be due to the compression of the nerve roots in the low back from a lumbar herniated disc, or a ruptured disc in the lumbar spine. Common symptoms of lumbar herniated discs include varying intensities of pain, muscle spasms or cramping, sciatica and leg weakness as well as loss of proper leg function. While these may not appear to be closely associated with each other, a lumbar herniated disc may also affect the cervical spine, manifesting symptoms of migraine and headache. The purpose of the following articles is to educate patients and demonstrate the relation between migraine pain and lumbar herniated disc, further discussing the treatment of these two common conditions.
