About this protocol

FORGE is built for radiographic and non-radiographic axial spondyloarthritis on three integrated pillars: spinal mobility and chest-expansion exercises targeting all BASMI domains; graduated walking-based HIIT addressing elevated cardiovascular risk; and progressive postural strengthening focused on anti-kyphosis extensor chains. Phase 3 introduces an adapted Norwegian 4×4. The programme is aligned with the 2022 ASAS-EULAR positioning of exercise as first-line therapy in axSpA.

Evidence base

FORGE is derived from systematic review and randomized controlled trial evidence in Axial Spondyloarthritis (axSpA). Protocol parameters — phase structure, load progression, and outcome measures — align with EULAR, ACR, and ASAS exercise-therapy recommendations. Outcome tracking favours open-access PROMIS instruments where validated equivalents exist.

Outcome measures

  • BASMI (Bath AS Metrology Index, 5 domains)
  • Chest Expansion at 4th intercostal space (cm)
  • BASDAI (Bath AS Disease Activity Index)
