NUCCA has concluded a pilot study for the supine leg check.

In this study done in May 2010 at Life Chiropractic College West, there was a 72% agreement between examiners for leg length inequality of at least 1/8 inch.  With leg length inequality of at least 1/4 inch, there was 100% reliability between examiners. This is important, because we base our decision whether to adjust or not primarily on leg length inequality.  This is showing that once doctors (or other examiners) are properly trained and check the leg length in a consistent manner, we can accurately determine whether there is a short leg.

We now know the proper sample size to use for the larger study, as well as the details needed to ensure an accurate leg check analysis.

This is the foundation for other research projects that NUCCA is working on.  The National Institute of Health (NIH) requires that NUCCA proves the validity of this protocol in order to provide funding for our other research.  What a blessing it is to have researchers working on NUCCA and validating what we NUCCA doctors do every day.  We look forward to future studies, and being published again in respected  journals, such as this hypertension study, published in the peer-reviewed Journal of Human Hypertension, which is the pilot to another study NUCCA is also working on.  This hypertension study was shown on Good Morning America, as well as on other national news shows and other television shows.
