Patients often ask me: "Should I rest or should I move?" The answer is nuanced. Complete bed rest delays recovery, but the wrong exercises can worsen symptoms. Here's how to navigate this.

Why Exercise Helps Sciatica

Movement helps sciatica in several ways:

Reduces inflammation: Gentle movement promotes blood flow and helps clear inflammatory mediators around the nerve.
Improves nerve mobility: Nerves need to glide through surrounding tissues. Gentle stretching can restore this mobility.
Strengthens supporting muscles: Core and hip strength reduce stress on the spine.
Prevents deconditioning: Prolonged inactivity leads to muscle atrophy and stiffness, making recovery harder.

Key principle: The goal is controlled, progressive movement that doesn't significantly increase leg pain. Some discomfort is okay; sharp, shooting pain that worsens is not.

Exercises That Help

These exercises are generally safe and beneficial for most sciatica patients. Start gently and progress as tolerated.

Walking

Why it helps: Low-impact, promotes blood flow, maintains conditioning.

How to do it: Start with 5-10 minutes, 2-3 times daily. Gradually increase duration as tolerated. Use good posture; avoid leaning forward.

When to modify: If walking increases leg pain significantly, try shorter intervals or walking in water (pool therapy).

Prone Press-Ups (McKenzie Extension)

Why it helps: Can help "centralize" pain (move it from leg toward back), which often predicts good outcomes.

How to do it: Lie face-down. Place hands under shoulders. Gently press upper body up, keeping hips on the floor. Hold 5-10 seconds. Repeat 10 times, several times daily.

When to stop: If leg pain worsens or moves further down the leg, this exercise may not be right for you. Try flexion-based exercises instead.

Knee-to-Chest Stretch

Why it helps: Gently stretches lower back and reduces pressure on nerve roots.

How to do it: Lie on back. Bring one knee toward chest, holding behind thigh. Hold 20-30 seconds. Repeat 3-5 times per leg, 2-3 times daily.

Variation: Bring both knees to chest for a deeper stretch (if tolerated).

Pelvic Tilts

Why it helps: Activates core muscles and improves spinal mobility.

How to do it: Lie on back, knees bent. Flatten lower back against floor by tilting pelvis. Hold 5 seconds. Repeat 10-15 times, 2-3 times daily.

Bird Dog Exercise

Why it helps: Strengthens core and improves spinal stability.

How to do it: Start on hands and knees. Extend opposite arm and leg. Hold 5-10 seconds. Alternate sides. Repeat 10 times per side, 1-2 times daily.

Progression: Start with just arm or leg extension if full bird dog is too difficult.

Piriformis Stretch

Why it helps: Releases tension in the piriformis muscle, which can compress the sciatic nerve.

How to do it: Lie on back. Cross affected leg over opposite knee (figure-4 position). Pull bottom leg toward chest. Hold 20-30 seconds. Repeat 3-5 times, 2-3 times daily.

Exercises to Avoid

These movements often worsen sciatica symptoms:

Toe touches and forward bends:

These increase pressure on discs and can worsen nerve compression.

Sit-ups and crunches:

These flex the spine and can aggravate disc herniations.

Leg lifts (both legs):

These create excessive load on the lower back.

High-impact activities:

Running, jumping, and contact sports can jar the spine and worsen symptoms.

Heavy lifting:

Especially with poor form (bending and twisting).

Aggressive hamstring stretches:

These can stretch the sciatic nerve excessively and increase pain.

Important: These are general guidelines. Some patients with stenosis do better with flexion exercises, while those with disc herniations often prefer extension. Work with a physical therapist to determine what's right for you.

When to Start Exercising

Timing matters. Here's my general approach:

Days 1-3: Acute Phase

Focus: Gentle movement, position changes, short walks. Avoid prolonged sitting or standing. Ice or heat as tolerated.

Days 4-14: Early Recovery

Focus: Begin gentle stretching and core activation. Walking 10-20 minutes, 2-3 times daily. Start McKenzie exercises or flexion stretches based on symptom response.

Weeks 3-6: Progressive Strengthening

Focus: Add strengthening exercises (bird dog, bridges, planks). Increase walking duration. Begin PT if not already started.

Weeks 7-12: Return to Activity

Focus: Gradually return to normal activities. Continue core strengthening. Address any movement patterns that contributed to the problem.

Role of Physical Therapy

Physical therapy is valuable for several reasons:

Individualized assessment: A PT can determine whether you respond better to flexion or extension exercises.
Proper form: Ensures you're doing exercises correctly and safely.
Progressive program: Adjusts exercises as you improve.
Manual therapy: Techniques like nerve gliding and soft tissue mobilization can complement exercises.

I typically recommend PT for patients whose symptoms persist beyond 2-3 weeks or who have significant functional limitations.

Warning Signs to Stop

Stop exercising and contact your doctor if you experience:

Significant increase in leg pain that doesn't resolve after stopping
New or worsening weakness
Numbness spreading or worsening
Bowel or bladder changes

Some discomfort during exercise is normal, but sharp, shooting pain that persists or worsens is a sign to modify or stop.
