Doctors, therapists, and nurses need a quick and easy tool to assess backache. A reliable and accurate measure of pain before and after treatment would be very helpful. In this study, physical therapists from Belgium test the Backache Index (BAI) for reliability and validity.
The BAI is based on a set of five movements in the standing position. Pain intensity is measured instead of spinal range of motion (ROM). A one-page form with drawings of each position is filled out. Each position is scored as follows:
The test was given to 75 back pain patients before and after physical therapy treatment. The results were compared with several other standard tests often given to back pain patients. Some of the more commonly known tests used included the Visual Analogue Scale (VAS), the McGill Pain Questionnaire, and the Oswestry Disability Questionnaire (ODQ).
The authors report the BAI has good reliability and validity. It is a good tool to measure overall restricted spinal movements in patients with low back pain. It can be used to show if treatment has been successful. It was not as useful in measuring changes in quality of life.
