Patients with chronic low back pain (CLBP) usually demonstrate poor postural control due to impaired core muscle function. Dynamic neuromuscular stabilization (DNS) is based on developmental kinesiology principles, utilizing infant motor patterns to treat motor disorders. DNS has been shown to improve postural control in cerebral palsy patients by activating core muscle. However, whether the DNS approach is superior for enhancing core muscle contractility and postural control in CLBP patients still remains unclear. This study aimed to compare the effects of DNS training and conventional core exercises on core muscle contractility and standing postural control in CLBP patients. Sixty CLBP patients were randomly assigned to a DNS group or a control group. Participants in the DNS group received DNS training, while those in the control group completed conventional core exercises. Both groups completed 12 sessions over 4 weeks (3 sessions/week, 50 min/session). Pre- and post-intervention evaluations included diagnostic musculoskeletal ultrasound to assess the change rate of core muscles (transversus abdominis (TrA), lumbar multifidus, and diaphragm), a balance assessment system to evaluate postural control performance (center of pressure displacement (COP)), and clinical questionnaires (Visual Analog Scale (VAS), Oswestry Disability Index (ODI), and Roland-Morris Disability Questionnaire (RDQ)) for pain intensity and disability. After 4 weeks, comparisons between both groups revea...
