Sciatica gets better with the right movements, not rest — most people recover without surgery.

Summary: Sciatica is when a nerve in your lower back gets squeezed and sends pain shooting down your leg. The fix isn't bed rest or stretching your hamstrings — it's finding the specific movement direction that takes pressure off the nerve and doing it frequently throughout the day. Most people see

  1. Here's what's really happening: A spinal disc is pressing on a nerve root, sending pain down your leg — 50% of cases resolve within 6 weeks with the right approach.
  2. The myth that won't die: Bed rest and hamstring stretching are two of the most common recommendations, and both make sciatica worse — bed rest deconditions you and stretching pulls on an already irritated nerve.

Think of the nerve in your lower back like a garden hose running through a gap in a fence. When the fence shifts (a disc bulge), it pinches the hose and nothing flows properly downstream — that's the pain shooting down your leg. The fix isn't to stop using the hose. It's to find the exact angle that opens the gap back up. That's what directional preference exercises do — they shift the fence post back so the hose runs free again. The nerve calms down on its own once the pressure is off.

What Works

Treatment approaches for sciatica

Tier 1 — Strong Evidence

Directional Preference Exercises (Extension) STRONG

Find the movement direction that makes your leg pain retreat toward your spine (centralization). For most people, this is extension — lying face down and pressing up. Do 10 reps with 3-5 second holds, every 2-3 hours. Functional improvement typically seen within 4-6 weeks.

JOSPT 2021 CPG: highest recommendation for lumbar radiculopathy.

Neural Mobilization (Nerve Sliders and Tensioners) STRONG

Gentle, rhythmic movements that help the nerve slide through its tunnel without pulling on it. 2-3 sets of 15-20 reps, 3-4 times per week. Start with sliders (less nerve load), progress to tensioners once comfortable. Measurable pain reduction within 2-4 weeks.

Multiple systematic reviews and meta-analyses confirm significant reductions in pain and disability.

See full treatment hierarchy (Tier 2 and Tier 3)

Tier 2 — Moderate Evidence

Spinal Mobilization / Manipulation MODERATE

Hands-on joint mobilizations to reduce pain and improve segmental mobility. JOSPT 2021 recommends for subacute and chronic presentations. Best used alongside exercise, not instead of it.

Core / Trunk Endurance Training MODERATE

Trunk stabilization exercises (side planks, bird-dogs, Biering-Sorensen holds) once acute nerve irritability subsides. Essential for preventing recurrence — Biering-Sorensen hold under 176 seconds predicts low back pain recurrence within the year.

Tier 3 — Emerging Evidence

Spinal Mobilization with Leg Movement EMERGING

Combined lumbar mobilization with active leg movement in quadruped position. Limited RCTs but promising for combined mechanical and neural effects.

What Doesn't Work

  • Bed rest — Prolongs recovery and increases deconditioning. The evidence is unambiguous.
  • Generic stretching (hamstrings, knee-to-chest) — Often worsens symptoms by pulling on the irritated nerve. Persists because "stretch it out" is deeply ingrained advice.
  • Gabapentinoids (gabapentin, pregabalin) — NICE 2020 explicitly advises against for sciatica. Mechanical compression does not respond to anticonvulsants.
  • Mechanical lumbar traction — No added benefit over extension exercises alone (JOSPT 2021). Expensive equipment, same outcomes.
  • TENS — No meaningful effect on radicular pain intensity. Lowest evidence tier.

Exercise Prescription

Prone Press-Ups

10 reps, 3-5s hold | Every 2-3 hrs

Lie face down, push upper body up keeping hips on floor. Hold, lower slowly.

Leg pain should stay the same or move UP toward your back (good). Stop if pain shoots further down.

Standing Extension

10 reps, 3-5s hold | Every 1-2 hrs at work

Stand, hands on lower back, lean backward gently.

Same rule — no increase in leg pain further down the leg. Good for office breaks.

Nerve Slider (Seated)

2-3 x 15-20 reps | 3-4x/week

Sit, slump forward, extend knee while looking down. Look up while bending knee back. Smooth rhythm.

Gentle pulling behind the leg is fine. No sharp pain — reduce range if sharp.

Nerve Slider (Lying)

2-3 x 15-20 reps | 3-4x/week

Lie on back, hold knee toward chest. Slowly straighten knee to ceiling, flex foot, then bend back.

Gentle tension fine. No shooting pain.

Biering-Sorensen Hold

1 max hold | 2-3x/week (weeks 3+)

Face down, upper body off edge of bed, partner holds legs. Hold body straight as long as possible.

Target: >130s (sedentary), >176s (recreational), >198s (competitive athlete).

Red Flags

When to Refer Immediately

  • Cauda Equina Syndrome: Bilateral leg pain + bladder/bowel problems + saddle area numbness + rapidly increasing weakness — EMERGENCY. Go to A&E/ER now.
  • Progressive neurological deficit: Worsening foot drop or leg weakness over days despite rest — URGENT neurosurgery/spine referral within 24-48 hours.
  • Spinal infection: Severe localized back pain + fever/chills + IV drug use or recent surgery — URGENT A&E.
  • Malignancy: Unexplained weight loss + cancer history + unremitting night pain — URGENT GP for investigations.
  • Spinal fracture: Significant trauma or minor trauma with osteoporosis + acute severe pain — URGENT A&E for imaging.

Refer to: A&E for CES/fracture/infection. Neurosurgery/Ortho Spine for progressive deficit or failed conservative (12+ weeks). GP for malignancy screening.

Real World vs Lab

Exercise Frequency

The research: McKenzie extensions every 2 hours (up to 5x/day) for best centralization results.

The reality: Most people can't interrupt their workday that often. Incomplete frequency leads to slower progress and perceived protocol failure.

Adjustment: Prescribe minimum 3x/day at fixed times (morning, lunch, evening). Standing extensions as a workplace-compatible alternative. More frequent = faster, but 3x/day still works.

Patient Expectations

The research: 50% resolve within 6 weeks naturally. Full resolution can take months.

The reality: Patients expect immediate relief. When improvement is slow, they catastrophize, develop fear-avoidance, or seek unnecessary imaging and surgery.

Adjustment: Set expectations at the first visit. "Most people see meaningful improvement within 6-12 weeks. If your leg pain is centralizing, that's a strong positive sign even if you still have some pain."

Home Exercise Technique

The research: Nerve glides show excellent results when supervised by a physical therapist.

The reality: Patients frequently convert "sliders" into "tensioners" at home by moving joints out of sync — making their symptoms worse, not better.

Adjustment: Extra time on technique education. Video demonstrations. Start with simpler distal-only sliders. Have patients demonstrate the movement back to you before prescribing it as homework.

Conviction: HIGH

What would change this: A large multi-center RCT (N>600) comparing isolated directional preference, isolated neurodynamics, and combined hybrid approach with 12-month follow-up. If the hybrid group achieves faster functional milestones without exacerbating nerve sensitivity, the protocol would shift from sequential to combined loading.

What's Actually Going On

Lumbar spine nerve root compression mechanism

The lumbosacral nerve roots — mainly L4, L5, and S1 — get compressed or chemically irritated. The most common cause is a disc herniation: the soft centre of a spinal disc pushes through its outer ring and presses directly on a nerve root.

The pain follows the affected nerve's path down the leg. Two signals tell you whether treatment is working:

Centralization — symptoms retreating back toward the spine. This is a strong positive sign. It means the nerve is being unloaded.

Peripheralization — symptoms spreading further down the leg. This is a warning. Whatever you're doing is making the compression worse.

Other causes include narrowing of the space where the nerve exits (lateral recess stenosis) and age-related changes in the facet joints. But in most working-age adults, a disc pressing on a nerve is the primary driver.

How to Identify It

Clinical assessment of lumbar radiculopathy

The Key Pattern

Unilateral leg pain below the knee that follows a specific nerve distribution. Worse with sitting and forward bending. Often accompanied by numbness, tingling, or weakness in the affected leg.

Top Diagnostic Tests

Dermatomal Map

L4: Medial leg, knee extension weakness. L5: Lateral leg, great toe extension weakness, foot drop. S1: Lateral foot/sole, ankle plantarflexion weakness, absent ankle reflex.

Key Differentials

The Debate

Bed Rest vs Staying Active

Historical practice

Bed rest prescribed for acute sciatica to allow disc healing.

vs

JOSPT 2021, NICE 2020

Stay active with directional preference exercises. Bed rest prolongs recovery and increases deconditioning.

Follow current: early activity with matched directional exercises. Bed rest only for acute pain flares (hours, not days).

Generic Stretching vs Neural Mobilization

Traditional approach

Hamstring stretches and knee-to-chest exercises prescribed for leg pain.

vs

Multiple RCTs, systematic reviews

Nerve sliders and tensioners outperform generic stretching. Stretching often worsens symptoms by over-tensioning the irritated nerve.

Follow current: replace generic stretching with neural mobilization techniques.

Gabapentinoids for Sciatica

Earlier neuropathic pain guidelines

Gabapentin/pregabalin prescribed as first-line for sciatic nerve pain.

vs

NICE 2020 Update

Explicitly advises against gabapentinoids for sciatica. Mechanical compression doesn't respond to anticonvulsants.

Follow current: avoid gabapentinoids entirely. NSAIDs short-term only if needed, not as primary treatment.

The Nuance

Surgery versus conservative management considerations

Surgery vs Conservative — What the Numbers Say

50-90%
Improve with conservative care within 3-6 months
1-2 yrs
When surgery and conservative outcomes equalize (SPORT trial, n=501)

Surgery gives faster pain relief at 3-6 months — that's real and valuable for quality of life. But long-term, outcomes are comparable for most patients.

Surgery IS indicated for: Cauda equina syndrome (emergency), progressive neurological deficit, intractable pain after 8-12 weeks of directed conservative care, large disc fragment with significant motor deficit.

Conservative IS sufficient for: Pain-dominant presentation (no progressive weakness), symptoms centralizing with exercises, patient can function with current pain levels.

Surgery is not a failure of conservative care when it's truly indicated — it's a valid treatment option. The decision comes down to severity of neurological deficit, response to treatment, and patient preferences.

Fear-Avoidance Is a Bigger Problem Than Most People Realize

High fear-avoidance beliefs, low mood, and long periods of sick leave are among the strongest negative predictive factors for sciatica recovery. Sometimes the biggest barrier to getting better isn't the disc — it's the belief that movement will make things worse. That's why patient education and expectation-setting are as important as the exercise prescription itself.

The Biering-Sorensen Number That Matters

The ability to hold a horizontal prone position for a specific duration predicts whether low back pain will return. Under 176 seconds? Strong predictor of recurrence within the year. Over 198 seconds? Predicts the absence of future low back pain. It's one of the most validated and practical return-to-activity tests available.
