Lumbar nerve-root disorder causing radiating leg pain with possible sensory, motor or reflex changes; distinguish radicular pain from radiculopathy with objective deficit.
Address safety, settle excessive irritability and maintain useful movement.
What to do
Screen neurological status and red flags; document baseline strength
Provide education and maintain tolerable activity
Find positions and movements that permit function without repeatedly provoking distal symptoms
Coordinate medical review when deficit is significant
Exercise dosage
Walking in tolerable intervals: 5–10 minutes, repeat as tolerated
Comfortable mobility: 5–10 reps; stop if progressive neurological symptoms occur
Progress when
Daily function is stable or improving.
No new red flags or progressive neurological deficit.
Exercise response returns to baseline by the following day.
Phase 2 — Mobility, Strength & Capacity
Restore the specific strength, mobility and control required by the condition.
What to do
Progress trunk and lower-limb strength
Use directional exercise only when repeated assessment shows a useful response
Introduce neural mobilisation gently when indicated and tolerated
Exercise dosage
Trunk/hip strengthening: 2–3 sets of 8–12, 2–3 days/week
Neural sliders: 1–2 sets of 8–10 gentle reps only if appropriate; avoid aggressive tensioning
Progress when
Target movement and resistance are tolerated with good quality.
Functional capacity is improving without sustained symptom flare.
Progression is based on objective performance and patient goals.
Phase 3 — Functional Restoration & Return to Activity
Rebuild real-world, occupational or sporting capacity.
What to do
Restore lifting, walking, work and sport capacity
Progress strength and endurance while monitoring neurological status
Plan graded return and recurrence strategies
Exercise dosage
Progress functional strengthening 2–4 sets of 6–15 reps
Increase walking and lifting demand gradually with symptom/neurological review
Progress when
Condition-specific return criteria are met.
Full task exposure is completed progressively.
No clinically meaningful deterioration during the following 24 hours.
Manual Therapy — Role & Application
Selected lumbar mobilization may be an adjunct when it improves function.
Neural mobilisation may be considered as part of a broader plan; avoid forceful techniques in progressive deficit.
Modalities — Use / Avoid
No passive modality reverses nerve-root compression.
Use symptom-relief strategies only as adjuncts; referral and monitoring take priority when deficits progress.
Return / Discharge Criteria
Neurological findings stable or improving
Walking, sitting and work tasks tolerated
Strength adequate for intended tasks
Clear escalation plan if weakness or red flags worsen
Common Clinical Mistakes
Calling every radiating pain radiculopathy without neurological assessment
Aggressive neural tensioning
Ignoring progressive weakness or cauda equina symptoms
Treating MRI findings rather than the clinical presentation
Clinical Pearls
Radicular pain and radiculopathy are related but not interchangeable terms.
Repeatedly document motor function when weakness is reported.

Connect assessment with management
Use the related PNA learning pathways to explore examination techniques and structured rehabilitation. A test result should always be interpreted alongside the history, full examination and clinical presentation.
