What Is Lumbar Radiculopathy?

Lumbar radiculopathy refers to irritation, compression, or sensitivity of a nerve root in the lower spine. These nerves exit the lumbar spine and travel into the hips, buttocks, legs, and feet. When one of these nerve roots becomes irritated, symptoms may be felt beyond the lower back itself.

Patients often describe lumbar radiculopathy as sciatica, pinched nerve in the lower back, nerve pain down the leg, radiating leg pain, tingling in the leg, or numbness in the foot. Symptoms may vary depending on which nerve root is affected and how sensitive the surrounding tissues are.

The underlying cause may involve disc changes, a herniated disc, bulging disc, facet joint irritation, spinal stiffness, or narrowing of the spaces where nerves exit the spine. These nerve exit spaces are known as the intervertebral foramina. When movement, posture, disc changes, joint irritation, or surrounding tissue tension alters the space around a nerve root, symptoms may increase.

Diagnosis of the underlying condition should be made by a licensed medical professional, especially when symptoms are persistent, worsening, or associated with weakness, numbness, or functional changes.

Individuals May Experience

• Pain that begins in the lower back and travels into the hip or leg

• Sciatica-like pain into the buttock, thigh, calf, or foot

• Tingling or numbness in the leg or foot

• Weakness in certain muscles of the leg

• Discomfort when sitting for long periods

• Increased pain with bending, lifting, twisting, or coughing

• Burning, sharp, or electric-like discomfort along the leg

• Difficulty standing upright during a flare-up

• Pain that changes with posture or position

• Muscle guarding in the lower back, glutes, or hips

• Reduced tolerance for walking, driving, work, or exercise

• Fear of movement due to radiating symptoms

More urgent medical assessment is required if symptoms include progressive leg weakness, numbness in the groin or saddle region, loss of bladder or bowel control, severe unrelenting pain, fever, unexplained weight loss, or symptoms after major trauma.

What Contributes to Lumbar Radiculopathy?

Several factors may contribute to irritation of lumbar nerves, including:

• Disc changes in the lower spine

• Herniated or bulging discs

• Facet joint irritation

• Narrowing of the nerve exit spaces

• Reduced mobility in the lumbar or thoracic spine

• Sacroiliac joint or pelvic restrictions

• Muscle imbalances in the core and hips

• Prolonged sitting posture

• Repetitive bending or lifting activities

• Poor load management during work, sport, or training

• Reduced hip mobility

• Protective muscle guarding around the lower back and pelvis

• Previous unresolved back injuries

Often, nerve irritation develops when mechanical stress accumulates in the spine over time. For example, prolonged sitting may increase sensitivity in the lower back and hips. Poor lifting mechanics may increase lumbar strain. Reduced hip mobility may force the lumbar spine to absorb more movement during bending, squatting, or twisting.

Lumbar radiculopathy can also be influenced by how the facet joints move. The facet joints help guide spinal movement. When these joints become restricted, compressed, or biomechanically dysfunctional, they may alter the available space where nerve roots exit the spine. If this narrowing or altered mechanics contributes to nerve compression or irritation, improving spinal movement may help reduce mechanical stress around the affected nerve pathway.

How Manual Therapy May Help

Manual therapy and rehabilitation may help improve spinal mechanics, reduce secondary muscle guarding, support nerve mobility, and improve tolerance to daily movement. The goal is not to force the spine or directly “push” a nerve back into place. Instead, care focuses on improving the mechanical environment around the irritated nerve and reducing compensation patterns that may increase stress through the spine.

A strong care plan may include spinal mobility work, core strengthening, hip strengthening, posture education, load management, and gradual return to activity.

Osteopathic Manual Therapy

Osteopathic Manual Therapy may involve evaluating how the lumbar spine, pelvis, hips, thoracic spine, ribs, and surrounding tissues move together. Restrictions in nearby joints or fascial tissues can increase mechanical stress around nerve pathways and contribute to protective guarding.

For lumbar radiculopathy, osteopathic care may also assess the biomechanics of the facet joints. When facet joints are not moving efficiently, they can influence the shape, loading, and available space around the intervertebral foramina, where spinal nerves exit. If nerve irritation is being influenced by compression or altered mechanics in this region, improving facet joint mobility and surrounding spinal mechanics may help reduce strain around the nerve pathway.

Treatment may include:

• Gentle mobilization of the lumbar spine

• Assessing and improving facet joint mobility

• Addressing sacroiliac joint mobility

• Improving thoracic spine movement to reduce lumbar strain

• Reducing fascial tension along the lower back and pelvis

• Assessing hip mobility and pelvic alignment

• Supporting coordinated movement through the spine and lower body

• Reducing protective muscle guarding around the lumbar spine

• Improving rib and diaphragm mobility when trunk tension is contributing

• Supporting better load distribution through the pelvis, hips, and spine

These approaches focus on improving mobility around the affected region and supporting more balanced movement of the spine, pelvis, and lower body.

Physiotherapy

Physiotherapy often focuses on restoring stability, strength, and control around the spine while reducing excessive load on irritated structures. This is especially important when lumbar radiculopathy affects sitting, walking, lifting, work, exercise, or sport.

Rehabilitation may involve:

• Core stabilization exercises

• Trunk control training

• Nerve mobility or nerve gliding techniques when appropriate

• Strengthening of the hips and gluteal muscles

• Movement retraining for bending, lifting, squatting, and twisting

• Postural education for sitting, driving, and desk work

• Graded exposure to sensitive movements

• Walking and activity progression

• Load management strategies

• Return-to-work, return-to-gym, or return-to-sport planning

These exercises help support the spine during movement and can improve tolerance to daily activities. Physiotherapy also helps reduce reliance on compensation patterns that may develop when the body avoids loading the irritated side.

Massage Therapy

Massage therapy may help address muscular tension that develops in response to spinal irritation or protective guarding. When a lumbar nerve root is irritated, the lower back, glutes, hips, hamstrings, and surrounding muscles may tighten in an attempt to protect the area.

Treatment may include:

• Reducing tightness in the lower back muscles

• Addressing tension in the glutes and hip muscles

• Improving circulation in surrounding tissues

• Supporting relaxation of protective muscle guarding

• Reducing compensatory tension patterns

• Helping improve comfort during flare-ups

• Supporting recovery alongside mobility and strengthening work

Massage therapy can help relieve muscular tension surrounding the irritated region of the spine, but it does not replace medical assessment or active rehabilitation when nerve-related symptoms are present.

Book an Assessment

If pain, tingling, numbness, burning, or weakness is travelling from your lower back into your hip, leg, or foot, our team can assess how your spine and surrounding joints are moving and identify factors that may be contributing to your symptoms.

A comprehensive assessment can help determine whether your symptoms may be influenced by lumbar mobility, facet joint mechanics, disc-related irritation, hip restriction, pelvic alignment, core strength, nerve sensitivity, posture, or compensation patterns.
