Physio Nexus Academy · Clinical Treatment Framework

Lumbar Radiculopathy / Sciatica

Treatment is guided by neurological status, symptom behavior and function. Exercise, education and graded activity are primary; manual therapy and neurodynamics are adjuncts.

Assess → classifyTreat → reassessLoad → progress

Clinical decision pathway

A structured plan, not a recipe

Clinician-led · Individualised
01

Understand

Screen safety, identify the likely clinical pattern and agree meaningful goals.

02

Select

Choose only interventions that match the patient's impairments and preferences.

03

Reassess

Repeat the same comparable sign or functional task after key interventions.

04

Progress

Build capacity and participation using measurable response, not session count.

Before choosing an intervention

Clinical reasoning

  1. 1Confirm nerve-root involvement using the neurological examination and symptom behavior rather than relying only on leg pain.
  2. 2Track motor deficit carefully. Progressive weakness changes urgency.
  3. 3Prefer interventions that centralize or reduce distal symptoms.

A practical starting sequence

First-session workflow

  1. 1Document dermatomes, myotomes, reflexes and neurodynamic findings.
  2. 2Screen cauda equina symptoms immediately.
  3. 3Test repeated movement or positions to identify centralization.
  4. 4Start a simple symptom-guided movement plus walking plan.

Assessment & examination

  1. 1Document baseline dermatomes, myotomes, reflexes and relevant functional strength
  2. 2Straight-leg raise/slump when relevant; interpret as part of the examination rather than a stand-alone diagnosis
  3. 3Repeated movement and centralization/peripheralization response without repeatedly provoking distal symptoms
  4. 4Walking and sitting tolerance, sleep and meaningful activity restrictions
  5. 5Screen for cauda equina symptoms, progressive motor deficit, severe bilateral neurological symptoms and suspected serious pathology
  6. 6Check whether findings fit a nerve-root pattern and consider peripheral nerve, hip and other differential diagnoses

Red flags & safety screen

  1. 1Cauda equina symptoms
  2. 2Progressive motor deficit
  3. 3Severe bilateral neurological symptoms
  4. 4Suspected fracture, infection or malignancy

Indication · dosage · response

Manual therapy application

  1. 1Gentle lumbar/thoracic mobilization may be used if it improves symptoms.
  2. 2Traction can be tested briefly; continue only if distal symptoms reduce or centralize.
  3. 3Avoid aggressive neural tensioning in a highly irritable nerve-root presentation.

Adapt to irritability and capacity

Exercise prescription & dosage

  1. 1Directional-preference exercise if present: 5–10 repetitions repeated through the day.
  2. 2Neural sliders: 10–20 gentle repetitions × 1–3 sets/day.
  3. 3Walking: several short bouts/day, gradually lengthened.
  4. 4Progress trunk, hip and leg strength to 2–3 sets × 6–15 repetitions when irritability falls.

Modalities & adjuncts

  1. 1Heat/TENS can be used for temporary pain control.
  2. 2No passive modality should delay neurological reassessment or active rehabilitation.

Progression & regression rules

  1. 1Progress when leg symptoms are less distal, neurological findings are stable and walking tolerance improves.
  2. 2Build from basic movement to loaded lifting and work tasks.
  3. 3Increase neural loading only after symptoms stop flaring easily.

Home programme

  1. 1Track whether symptoms centralize or spread distally
  2. 2Avoid prolonged inactivity
  3. 3Frequent tolerable walking and movement

Outcome measures

  1. 1NPRS
  2. 2Oswestry Disability Index
  3. 3Straight-leg raise tolerance
  4. 4Neurological status
  5. 5Walking/sitting tolerance

Common clinical mistakes

  1. 1Treating all sciatica with hamstring stretching.
  2. 2Missing cauda equina symptoms.
  3. 3Ignoring progressive weakness.
  4. 4Using repeated peripheralizing movements.

Patient education & self-management

  1. 1Explain that leg symptoms can change before back pain fully resolves.
  2. 2Teach emergency symptoms: saddle numbness, bladder/bowel dysfunction or rapidly worsening weakness.
  3. 3Encourage activity within symptom limits rather than prolonged bed rest.

Referral & escalation

  1. 1Urgent medical/surgical assessment for cauda equina or progressive motor loss
  2. 2Medical review for severe persistent radicular pain with neurological impairment

Clinical use & safety note

This is an educational clinical framework, not an individual prescription or a substitute for diagnosis, medical assessment, local protocols or professional judgement. Exercise dose, manual techniques and adjuncts must be adapted to examination findings, irritability, comorbidities, precautions, patient goals and response. Obtain informed consent, work within training and scope, and refer when indicated. Do not apply every intervention listed to every patient.

The PNA treatment principle

The best plan is not the one with the most techniques. It is the one that identifies the patient's main problem, selects a defensible intervention, measures the response and steadily restores meaningful function.
