More Information | Bryan Cervical Disc Study - Rick Sasso, MD

In my prior blog entry, I talked about the Bryan Cervical Artificial Disc study that has recently concluded. To evaluate patient outcomes and functionality for this spine study, one measurement used was the neck disability index (NDI). With this assessment, patients provide a self-evaluation and answer a series of questions of how their neck pain affects their ability to manage everyday life.

Prior to surgery the average NDI score for patients in both the Bryan Cervical Artificial Disc group and the control group was 51. The average post-operative score in the Bryan group was 10, and for the control group it was 16.7

Here is the link to a NDI questionnaire.
