Leg Length
Leg Length Alignment Asymmetry In A Non-clinical Population And Its Correlation To A Decrease In General Health As Measured By The SF-12: A Pilot Study
The purpose of this study was to determine if there is an association between a test commonly used by chiropractors as a sign of subluxation/joint dysfunction – supine leg length alignment (LLA) asymmetry – and health-related quality of life as measured by the SF-12 questionnaire, in a non-clinical population.
Conclusion:
This pilot study suggests that in this group of volunteers (n=50) from the non-clinical general population, those who demonstrated a commonly used sign of subluxation/joint dysfunction – supine leg length alignment asymmetry – had a significantly (P=0.017) lower measure of general health as determined by the SF-12 survey than those volunteers without such asymmetry. Further investigation to clarify this relationship and to establish whether there is a connection between the putative entity of chiropractic subluxation and unloaded leg length alignment asymmetry is recommended.
