What it is
Thoracic facet joint dysfunction is characterised by painful stiffness in the small joints located at the back of the mid-back. It follows minor joint irritation, capsular strain, or postural overload. Pain often sits to one side and limits extension or rotation. Breathing may feel tight when the rib cage expands.
Treatment restores joint glide and muscle control while easing pain. Most improve with a brief, structured plan that targets movement and endurance.
What happens when it occurs
Guarded paraspinal muscles compress the joint, limiting its glide. Capsular tissues become sensitive. Restoring smooth motion through graded mobility and breathing drills helps alleviate pain. Strength for scapular stabilisers and back extensors keeps the gains.
Common causes and risk factors
- Prolonged sitting with a rounded posture
- Twisting or reaching under load
- Awkward sleep positions
- Previous mid-back pain episodes
Who is most affected
Adults in desk roles, drivers, and manual workers who twist or reach frequently in Australian workplaces.
Typical symptoms
- Local ache on one side of the mid-back
- Pain with extension or rotation and morning stiffness
- Occasional rib cage tightness with deep breaths
When to seek care
If pain limits work, driving, or sleep for more than a few days, or if chest pain, shortness of breath, or other medical red flags occur.
How we diagnose
History and movement testing, palpation of segmental tenderness, breathing assessment, and exclusion of nerve or visceral red flags. Imaging is used selectively.
Management
- Graded thoracic mobility and breathing drills
- Back extensor and scapular endurance training
- Pectoral mobility and thoracic extension practice at the desk
- Manual therapy, where appropriate, to assist with the glide
- Task and sleeping position adjustments
Rehabilitation milestones
Phase 1 week 0 to 1: pain control, gentle mobility, breathing practice.
Phase 2 weeks 1 to 4: endurance training and movement re-education.
Phase 3 weeks 4 to 8: task and sport drills at volume, self-management skills.
Readiness to progress
- Restored rotation and extension without apprehension
- Endurance targets met for back extensors and scapular muscles
- Workdays completed without next-day flare
Prevention
- Alternate tasks and positions
- Maintain thoracic mobility and pulling strength
- Plan graded exposure for reaching and twisting work
Australia snapshot
- Common in office and trade settings across Australia
- Strong short-term outcomes with mobility and endurance programmes
- Most do not require imaging or injections
Latest insights
Restore glide, then protect it with endurance.
Breathing drills help relax guarding and ease rib cage motion.
