While people with NSLBP appear to move and posture themselves differently from those without NSLBP, changes in movement and posture infrequently relate to improvements in NSLBP when analysed at a group\u2010level. Additionally, little is known about how movement or posture change when clinical outcome improves.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Within\u2010person relationships were investigated using a replicated, repeated measures, single\u2010case design in 12 people with persistent, disabling NSLBP. Individually relevant movement and posture were captured using wearable sensors on up to 20 occasions over a 22\u2010week period (5\u2010week baseline, 12\u2010week physiotherapy\u2010led intervention, 5\u2010week follow\u2010up), while pain and activity limitation were collected concomitantly. A series of cross\u2010correlation analyses estimated the presence, strength, and direction of relationships.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Many participants (<jats:italic>n<\/jats:italic>\u00a0=\u00a010\/12) had strong (e.g. <jats:italic>r<\/jats:italic>\u00a0=\u00a00.91, <jats:italic>p<\/jats:italic>\u00a0=\u00a0&lt;0.001) relationships between changes in movement or posture and changes in pain and activity limitation, while some showed no strong association. Where relationships were observed, clinical improvement predominantly (93% or 57\/61 relationships) related to increased spinal movement range and velocity during forward bending and lifting, reduced lumbar muscle EMG activity at maximum voluntary flexion, and increased posterior\u2010pelvic\u2010tilt during sitting and standing.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Within\u2010person changes to individually relevant movement and posture appear to often relate to clinical outcome, but not always.
