Understanding SRS and Oswestry Scores

What is the SRS-22?

The SRS-22 is used to measure how a spinal deformity, such as scoliosis, is affecting a patient’s overall life. It is a questionnaire for the patient that covers five aspects of pain and how it affects the patient. The five aspects are:
  • Pain
  • Function
  • Self-Image
  • Mental Health
  • Satisfaction

For each of the 22 questions, the patient chooses which of five statements best describes them. For example, one question is:

What is your current level of work/school activity? 100% normal 75% normal 50% normal 25% normal 0% normal

Each statement has a point value assigned to it, and after the patient fills out the questionnaire, Dr. Bridwell adds up the points.

A low SRS-22 score means that the pathology—the condition the patient has—affects the patient’s life a lot.

A high SRS-22 score means that the pathology doesn’t affect the patient’s life very much.

An SRS satisfaction score of 10 out of 10 means maximum satisfaction—the highest possible satisfaction with the procedure.

Having the patient do an SRS-22 questionnaire before and after treatment allows Dr. Bridwell to see how well the treatment worked to improve the patient’s life.

What is the Oswestry Disability Index (ODI)?

The Oswestry Disability Index (ODI) is used to measure how lumbar spine pain is affecting a patient’s overall life. It is a questionnaire for the patient that covers 10 aspects of pain and how it limits certain activities. The 10 sections are:
  • Pain Intensity
  • Personal Care
  • Lifting
  • Walking
  • Sitting
  • Standing
  • Sleeping
  • Sex Life (if applicable)
  • Social Life
  • Travelling
In each section, the patient chooses which of six statements best describes them. For example, in the Pain Intensity section, the statements are:
  • I can tolerate the pain I have without having to use pain killers.
  • The pain is bad but I manage without taking pain killers.
  • Pain killers give complete relief from pain.
  • Pain killers give moderate relief from pain.
  • Pain killers give very little relief from pain.
  • Pain killers have no effect on the pain and I do not use them.
Each statement has a point value assigned to it, and after the patient fills out the questionnaire, Dr. Bridwell adds up the points.

A low Oswestry score means that the pathology—the condition the patient has—doesn’t affect the patient’s life very much.

A high Oswestry score means that the pathology affects the patient’s life a lot.

Having the patient do an Oswestry questionnaire before and after treatment allows Dr. Bridwell to see how well the treatment worked to improve the patient’s life.
