APPENDIX A: IMAGING DECISION ALGORITHM

When to Image

Immediate MRI (STAT): - Cauda equina syndrome symptoms - Progressive motor deficit (<4/5 or worsening) - Myelopathic signs (cervical) - Fever + back pain (add contrast for abscess) - History of malignancy + new back/neck pain - IV drug use + back pain

Urgent MRI (within 1-2 weeks): - Motor weakness (4/5) without progression - Intractable pain despite medications - Suspicion for tumor or infection without acute neuro deficit

Routine MRI (4-6 weeks): - Persistent radicular symptoms despite conservative treatment - To confirm level before intervention or surgery - Correlation with EMG findings

No MRI Needed: - Mild radicular symptoms <6 weeks responding to conservative treatment - No red flags present - Improving trajectory


APPENDIX B: PHYSICAL THERAPY MODALITIES

Initial Phase (Week 1-2)

  • Pain modulation: TENS, ice/heat, manual therapy
  • Gentle ROM exercises
  • Positioning education
  • Nerve gliding/flossing exercises

Acute Phase (Week 2-4)

  • McKenzie exercises (extension-based for disc, flexion-based for stenosis)
  • Core stabilization (transverse abdominis activation)
  • Postural training
  • Progressive nerve mobilization

Strengthening Phase (Week 4-12)

  • Progressive core strengthening (plank, bird-dog, bridges)
  • Hip and leg strengthening
  • Functional movement training
  • Aerobic conditioning (walking, pool therapy)

Maintenance Phase (Ongoing)

  • Independent home exercise program
  • Return to activities with proper mechanics
  • Work conditioning if applicable
  • Ongoing core and flexibility maintenance
