Sensor-based postural feedback is more effective than conventional feedback to improve lumbopelvic movement control in patients with chronic low back pain: a randomised controlled trial.

The study tested only one exercise session and measured movement control immediately after, so it does not show whether the improvement lasts or applies to activities outside the two tested tasks. Motor learning was assessed only by a transfer test, not by a retention test. Ten patients with chronic low back pain and seven healthy participants were excluded after the session because of baseline movement control performance. Participants had to have baseline lumbar range of motion above 10 degrees, so people with very restricted lumbar movement at baseline were excluded. Lower limb joint mobility was not measured at baseline, and the sensors did not capture thoracic spine compensation. The primary outcomes were kinematic movement control measures, not pain, disability, or patient-important function.

Do not conclude that sensor-based feedback treats chronic low back pain or produces lasting motor learning. This trial measured only immediate lumbar and hip movement control after one session, and it did not show long-term retention or changes in pain and disability.
