🦴 McKenzie Technique (MDT – Mechanical Diagnosis & Therapy)
The McKenzie technique is a physiotherapy method mainly used for disc protrusion, sciatica, and mechanical low back pain very useful in cases with leg pain or cramping due to disc issues.
🎯 Main Principle
👉 Centralization of pain
Pain moves from the leg > buttock > back, which means the disc pressure on the nerve is reducing ✅
🧠 How McKenzie Works
Repeated movements (mostly extension)
Reduces disc bulge pressure
Restores normal disc position
Decreases nerve root irritation
📌 Most lumbar disc protrusions respond best to extension-based exercises.
🧍♂️ Assessment (Very Important)
Before exercises, the therapist checks:
Direction that reduces leg pain
Direction that centralizes symptoms
Direction that peripherals pain ❌ (must avoid)
🔁 McKenzie Extension Exercises (Lumbar)
1️⃣ Prone Lying
🛏️ Lie on stomach
⏱️ 2–5 minutes
✔ Relaxes spine
✔ First step for acute pain
2️⃣ Prone on Elbows
🦵 Lie on stomach
⬆ Raise upper body on elbows
⏱️ Hold 10–30 sec × 5–10 reps
✔ Begins extension
✔ Often reduces leg pain
3️⃣ Prone Press-Ups (Cobra)
👐 Hands under shoulders
⬆ Push chest up, hips stay on bed
🔁 10 reps × every 2–3 hours
✔ Most effective for disc protrusion
✔ Leg pain should reduce or move upward
⚠ Stop if leg pain increases.
4️⃣ Standing Back Extension
🧍♂️ Hands on lower back
⬅ Lean backward
🔁 10 reps
✔ Useful during work/sitting breaks
🚫 What to Avoid Initially
❌ Forward bending
❌ Sitting for long time
❌ Heavy lifting
❌ Twisting
🦵 For Leg Cramping (Sciatic Nerve)
After pain centralizes:
✔ Sciatic nerve glides
✔ Gentle hamstring stretch
✔ Calf stretching
⚠ When NOT to Use McKenzie
🚫 Spinal fracture
🚫 Tumor/infection
🚫 Cauda equina syndrome
🚫 Severe spinal stenosis
🏠 Home Advice
Use lumbar roll while sitting
Sleep on side with pillow between knees
Walk regularly 🚶♂️
📌 Summary
👉 McKenzie technique = repeated extension movements
👉 Best for disc protrusion with leg pain/cramping
👉 Goal = centralization of symptoms
