“The answer only matters if you are asking the right question.”? Our process for getting to the right questions: We insist on working from first principles, stress testing our ideas, reproducing results and inventing elegant solutions to complicated problems. For example: We invented a clinical assessment to measure and grade lumbar spine flexion. Think about it, when was the last time you MEASURED this extremely important range? Our research shows lumbar flexion is the priority restriction in 85% of low back pain patients. Maybe there is a back pain epidemic because doctors need to ask better questions?
