Answer to the Letter to the Editor of P. Kent et al. concerning "Predicting a beneficial response to motor control training in patients with low back pain: a longitudinal cohort study" by Hides JA, et al. (Eur Spine J. 2019; https://doi.org/10.1007/s00586-019-06045-7)

[摘要] Thank you for reading our paper. We acknowledge the point raised that we should have consistently described the variables as ‘predictors of outcome’ rather than using the term ‘predictors of treatment response’, although we defned outcome as improvement in pain level and symptoms.
