Comparison of Abdominal Expansion and Abdominal Drawing-In Training With Manual and Verbal Cueing in Chronic Non-Specific Low Back Pain

Официальное название

A Randomized Controlled Trial Comparing Abdominal Expansion and Abdominal Drawing-In Training With Manual and Verbal Cueing in Individuals With Chronic Non-Specific Low Back Pain

Обзор

This study aims to investigate the interactive effects of two core stability training strategies-abdominal drawing-in manoeuvre (ADIM) and Dynamic Neuromusculoskeletal Stabilization abdominal expansion (DNS-AE)-and two instructional approaches (verbal cueing and manual facilitation) on training outcomes in individuals with chronic non-specific low back pain. A 2×2 factorial randomized controlled trial design will be employed. Ninety-six participants with chronic non-specific low back pain will be randomly allocated, using block randomization, to one of four intervention groups in equal proportions. All groups will receive a 4-week intervention program, with training conducted twice per week. Outcome measures will be assessed at four time points: before the intervention (baseline), immediately after the first training session, at the completion of the 4-week intervention, and at a 3-month follow-up, to evaluate short-term and mid-term effects as well as the sustainability of training outcomes.

Вмешательства

• Поведенческое Abdominal Drawing-In Manoeuvre Training
  Abdominal drawing-in manoeuvre (ADIM) training is a core stability exercise strategy emphasizing selective activation and coordination of the deep abdominal musculature to enhance local trunk stability. Participants receive individualized, one-on-one training delivered by licensed physical therapists, conducted twice weekly for 4 weeks. Training is performed across functional positions and task-specific movements, with instruction provided using either verbal cueing or manual facilitation accord
• Поведенческое Dynamic Neuromusculoskeletal Stabilization Abdominal Expansion Training
  Dynamic Neuromusculoskeletal Stabilization abdominal expansion (DNS-AE) training focuses on coordinated breathing and abdominal expansion to facilitate intra-abdominal pressure regulation and integrated postural control. Participants receive individualized, one-on-one training delivered by licensed physical therapists, conducted twice weekly for 4 weeks. Training is performed across functional positions and task-specific movements, with instruction provided using either verbal cueing or manual f
