Research Findings

YHLB Yoga Research - Group Standing Chair Twist

One of the largest  and most significant yoga research trials – robust and rigorous with multiple published papers – University of York (York Trials Unit, Department of Health Sciences, UK) / Arthritis Research UK / Yoga for Healthy Lower Backs (YHLB) programme

The two yoga teacher/therapists who were consultants and trial management steering group members for the original University of York research trial, set up this website and not-for-profit social enterprise.  They acknowledged that this randomised control trial had taken yoga research ‘up a level’.  Since the original research, we continue to evaluate and assess the performance of the programme – performance is consistent and outcomes have improved in all cohort case studies comparative to the original trial findings.
