Question

Is the Functional Rating Index, from the Institute of Evidence-Based Chiropractic, valid and acceptable? Or do we have to use Oswestry and NDI?

Answer

You can use any outcome assessment questionnaire that has been normalized and vetted for the target population and can be scored so you can compare the results from one to the other. Therefore, this choice should be acceptable. Be aware of any payer-specific requirements for outcome assessment measurement tools.
