About Lumbar Spinal Stenosis

LSS is a frequent cause of chronic low back and leg pain. It often results from a degenerative process that causes narrowing of the central spinal canal, lateral recesses, or intervertebral foramen. This narrowing compresses the neurovascular structures, leading to symptomatic LSS, most frequently in individuals over the age of 60. While LSS can also be congenital, this care pathway focuses on degenerative LSS. Symptomatic LSS is described as neurogenic claudication, which can be characterized by unilateral or bilateral leg symptoms. This can include pain, cramping, numbness, balance difficulty, or weakness. Symptomatic LSS is amenable to conservative care; however, underlying pathologies requiring medical attention should be ruled out such as cauda equina syndrome, fracture, infection, or tumour. 

About CCG Care Pathways

Purpose

CCG care pathways provide structured, evidence-based guidance for clinicians delivering conservative, non-operative care for common musculoskeletal conditions. They outline key steps of the clinical encounter, support safe and appropriate decision-making, and assist with referral or co-management when indicated. Pathways are designed as practical, user-friendly tools that complement, not replace, clinical judgment.

Development

Pathways are developed using the best available evidence from high-quality clinical practice guidelines when they exist, and from systematic reviews and expert consensus when guideline evidence is limited or evolving. Content is reviewed periodically to reflect emerging research and current best practices. Input from clinicians, educators, and researchers helps ensure pathways remain relevant, aligned with real-world practice, and responsive to user needs.

Principles of Conservative Care

Musculoskeletal conditions are multifactorial and often influenced by physical, psychological, social, and environmental factors. As such, there is no one-size-fits-all approach to care. Effective management should be ethical, evidence-informed, transparent, flexible, and tailored to individual needs. Shared decision-making ensures care aligns with patient goals and values. Ongoing monitoring and outcome assessment support a person-centred approach and enable timely adjustments to care plans. Care may be delivered in-person, virtually, or through hybrid models, guided by patient preference, access, and clinical judgment.

Disclaimer

CCG care pathways are intended to support, not substitute for, professional clinical decision-making or the advice of a qualified healthcare provider. Recommendations are evidence-informed and presented in simplified, accessible language to support clinical understanding and application. Terms used throughout are not intended as formal diagnostic or billing terminology, nor are pathways prescriptive, authoritative, or regulatory.

Providers are expected to apply their clinical expertise and consult authoritative sources such as regulatory standards and policies, diagnostic classification systems (e.g., ICD-10-CA), scope-of-practice documents, continuing professional education resources, and peer-reviewed literature. Pathways may not apply to every clinical scenario and should always be interpreted in the context of individual patient needs.

Lumbar Spinal Stenosis Care Pathway

1. Record Keeping

Accurate, timely, and comprehensive documentation is an essential component of high-quality, evidence-based care. Clinical records must clearly reflect patient interactions, clinical reasoning, and progress over time, and should meet all jurisdictional regulatory standards.

Providers are encouraged to use a structured note format, such as the SOAP framework, to support consistency, clarity, and continuity of care.

Subjective: Document the patient’s reported symptoms, concerns, functional changes, contextual factors (e.g., psychosocial or environmental influences), and responses to prior care.

Objective: Record measurable or observable findings, including physical examination results, relevant diagnostic tests, functional assessments, and any clinically significant changes.

Assessment: Provide the clinical interpretation of findings, including diagnostic impressions or updates, identification of key risk factors or modifiers, and evaluation of the patient’s status or progression.

Plan: Outline the management strategy, including treatments delivered, modifications made, patient education and self-management recommendations, referrals, co-management decisions, and planned follow-up.

Documentation should be completed contemporaneously and maintained in accordance with regulatory requirements for privacy, security, and record retention. High-quality records support patient safety, facilitate interprofessional communication, enable shared decision-making, and promote continuity and accountability in care.

2. Informed Consent
  • Definition: A process where the patient voluntarily agrees to proposed healthcare interventions after receiving adequate information on the nature, benefits, risks, and alternatives.
  • Key Aspects:
    • Prior to interaction: Obtain consent before any diagnostic testing or treatment. Ensure the patient understands the planned examinations, treatments, expected outcomes, and is given the opportunity to ask questions.
    • Voluntarily and specific: Consent must be given willingly, without coercion, and pertain to the specific condition and proposed treatment. The patient should also understand that they can withdraw consent at any time. 
    • Transparent process: Consent must be obtained honestly, with a clear explanation of the condition and proposed interventions. Consent is not a one-time event, and involves ongoing discussions with the patient.
    • Patient understanding and agreement:
      • Diagnosis/prognosis: Explain findings clearly, using understandable language and visuals if needed.
      • Treatment plan: Outline recommended treatments and how they align with patient goals. Discuss benefits, risks, and alternatives.
      • Questions: Encourage questions and confirm understanding (e.g., “teach-back”).
    • Documentation: Record the consent process, including information provided, patient questions, and explicit consent given.
3. Health History
  • Apply cultural awareness and trauma-informed care principles.
  • Sociodemographic information: Age, gender, sex, race/ethnicity.
  • Main complaint: Location, onset, duration, radiation, frequency, intensity, character, aggravating/relieving factors, associated symptoms.
  • Body systems review: Neurologic, cardiovascular, genitourinary, gastrointestinal, muscles and joints, eyes/ears/nose/throat, respiratory, skin, mental health, reproductive.
  • Health, lifestyle, family, social, and occupational history: Past medical conditions, medications (including opioids), injuries, hospitalizations, surgeries, diet, exercise, sleep habits, smoking, alcohol/substance use, family support, caregiver responsibilities, work environment.
  • Social determinants of health: employment, childcare, education, nutrition, housing, domestic violence, child maltreatment, discrimination, social isolation.
  • Previous treatments and responses: Document prior treatments, effectiveness and any adverse events.
  • Beliefs and expectations: Assess patient understanding of their condition, treatment goals, and outcome expectations.
  • Flag considerations: Identify red, orange, and yellow flags for potential referrals.

​​Outcomes Assessments: Prioritize approaches that align with the patient’s specific goals and clinical presentation.

4. Red Flags : Differential Diagnosis Requiring Medical Referral

ACTION: Refer to emergency care immediately for red flags:

  • Cauda Equina Syndrome: Saddle anesthesia, bladder/bowel dysfunction, bilateral radicular signs.
  • Spinal Infection: Immunosuppression, recent infection or surgery, TB (tuberculosis) history, unexplained systemic symptoms (e.g., fever, chills), IV drug use, poor living conditions.
  • Traumatic Spinal Fracture: Severe trauma.

ACTION: Refer to appropriate medical provider:

  • Non-traumatic Spinal Fracture: Sudden onset, localized severe pain, osteoporosis, corticosteroid use, female sex, older age (>60), history of spinal fracture or cancer. 
  • Spinal Malignancy: Progressive pain, history of cancer, constitutional symptoms (e.g., fatigue, weight loss, night pain).
  • Inflammatory Arthritides (e.g., spondyloarthropathies): Morning stiffness >1-hour, constitutional symptoms (e.g., fatigue, weight loss, fever), symmetrical joint pain, joint swelling and deformity. 
  • Referred Pain: (from abdominal/pelvic visceral conditions): Abdominal or pelvic tenderness.
  • Cervical Spondylotic Myelopathy: Gait disturbances, hand clumsiness, non-dermatomal numbness/weakness, bowel/bladder dysfunction, coordination problems.
5. Orange Flags: Symptoms of Psychiatric Disorders Requiring Referral

Clinicians should promptly address symptoms of potential mental health disorders to prevent harm through appropriate and timely referrals.

ACTION: Refer for immediate care (emergency department, medical/mental health provider):

  • Suicidal ideation: Thoughts, plans, or statements about suicide or feelings of hopelessness.   
  • Severe, acute symptoms: Acute psychological distress, such as psychosis, severe panic.
  • Ideation of harm: Intent or plans to self-harm, commit violence, or harm others.

ACTION: Refer to appropriate medical/mental health provider:

  • Persistent, non-urgent symptoms: Symptoms affecting daily functioning (e.g., low mood, anxiety, sleep disturbances, social withdrawal, substance use).

ACTION: Co-management by non-medical/mental health providers:

  • Triage: Ensure primary management by medical/psychiatric providers.
  • Musculoskeletal (MSK) treatment: Manage MSK conditions related to or comorbid with psychological disorders.
  • Screening tools: Selectively use tools to monitor symptoms and severity, guide care, and support escalation without implying a diagnosis. Tools include:
    • PHQ-9 (depressive symptoms)
    • GAD-7 (anxiety symptoms)
    • FABQ (fear related to physical activity/work) 
    • PCS (catastrophic thoughts) 
    • ORT (opioid risk)
6. Yellow Flags: Psychosocial Factors that May Delay Recovery

Non-health barriers can delay recovery; early identification and intervention can enhance outcomes.

Factors:

  • Individual: Worry, fear of movement, low recovery expectations, limited self-efficacy, reliance on passive treatments, activity avoidance.
  • Social: Lack of family/social support, limited connections.
  • Socioeconomic: Employment status, financial stress, litigation/compensation.
  • Environmental/cultural: Social inequality, unsafe/unsupportive environments.
  • Life events: Major transitions (e.g., divorce, job loss), chronic stressors (e.g., caregiving).
  • Work/school: High stress, poor work-life balance, limited accommodations for injury/illness.

ACTION: Co-management by non-medical/mental health providers: 

  • Education & self-care: Provide resources for (e.g., stress management, coping strategies, graded activity).  
  • Monitor & coordinate: Regularly assess psychosocial challenges; refer to medical/mental health provider if persistent.
  • Screening tools: Selectively use tools to monitor symptoms and severity, guide care, and support escalation (aligned with Orange Flag guidance), without implying a diagnosis. Tools include:
    • PHQ-9 (depressive symptoms)
    • GAD-7 (anxiety symptoms)
    • FABQ (fear related to physical activity/work) 
    • PCS (catastrophic thoughts) 
    • ORT (opioid risk)

7. Physical Examination
  • Observation: Abnormalities, posture, balance, movements, facial expression, gait, walking capacity (measured by distance or time).
  • Range of Motion: Active, passive, resisted (flexion, extension, lateral flexion, rotation).
  • Palpation: Bone, joint, and muscle for tenderness, swelling, muscle tightness, or temperature changes.
  • Neurological Examination: Motor strength, sensory and reflex testing (L4, L5, S1); upper and lower motor neuron signs; balance testing (e.g. tandem gait, Romberg’s)
  • Special/Orthopedic Tests: Select as appropriate based on clinical judgment.
  • Advanced Diagnostics: Advanced imaging (e.g., MRI, CT) to guide diagnosis and surgical management.

8. Diagnostic Criteria for LSS

LSS with Neurogenic Claudication (central stenosis)

  • Location: Widespread lower extremity pain with or without LBP.
  • Signs/Symptoms: Aching, cramping, or burning pain, most commonly in both legs, but can be unilateral. May include tingling, paresthesia, numbness, weakness, and balance difficulties. Aggravated by extension activities (e.g., walking, standing); relieved by forward bending, sitting, or lying down. 
  • Physical Exam: Pain reproduced by physical tests; possible neurological deficits.

LSS with Radicular Unilateral Leg Pain (lateral recess or foraminal stenosis)

  • Location: Unilateral lower extremity pain with or without LBP.
  • Signs/Symptoms: Pain following a dermatomal pattern associated with a nerve root in one leg. Aggravated by extension activities (e.g., walking, standing); less influenced by postural changes. 
  • Physical Exam: Pain reproduced by physical tests; possible neurological deficits.

9. Treatment Considerations for LSS (with central or lateral stenosis)

Approach to Treatment

The treatments outlined in this section reflect core domains of care consistently identified across high-quality clinical practice guidelines and established clinical practices. These include interventions shown to improve patient-important outcomes such as pain, function, and quality of life. Management plans should be tailored to the individual’s needs, goals, and preferences, taking into account clinical presentation, response to care, and contextual factors.

Not all domains need to be included in every care plan or at every stage of recovery. Clinicians are expected to apply professional judgment in selecting the most relevant components based on the clinical context.

This pathway is not prescriptive, nor does it list every possible intervention. Readers are encouraged to consult individual guidelines for specific treatment protocols, dosage, and condition-specific considerations.

While a range of other interventions may be in use, such as passive physical modalities, these have mixed or limited evidence of clinical benefit and are therefore not recommended for routine use. If applied, such therapies should be used as adjuncts to the core, evidence-based components of care, and not as standalone treatment.

  1. Education and Self-Management:
    • Education & reassurance: Inform patients about the nature of LSS and the importance of maintaining activity. Reassure them that neurogenic claudication is often manageable with conservative care.
    • Address yellow flags: Psychosocial factors such as fear-avoidance and depression should be identified and addressed early (e.g., education, CBT).
    • Maintain activities of daily living: To prevent deconditioning.
    • Self-care: Promote physical activity, nutrition, proper sleep hygiene, stress management, healthy body weight, no smoking/substance abuse.
    • Engage in social and work activities: Helps maintain mental and emotional well-being.
    • Mind-body interventions: E.g., mindfulness, meditation, tai chi.
    • Mobility assistive devices: E.g., walkers, canes to help maintain mobility and functional independence.
  2. Exercise therapy: Walking, functional exercise, flexion-based exercise, strength training (home-based or supervised).
  3. Medical referral/surgical consultation: For worsening symptoms or failed treatment (e.g., significant/progressive neurological deficits, severe pain unresponsive to conservative care).
  4. Manual therapy: As part of the management plan, consider incorporating spinal manipulation, mobilization, or soft tissue techniques to reduce pain and improve function.
  5. Medications: E.g., serotonin-norepinephrine reuptake inhibitors, tricyclic antidepressants. Avoid long-term use and opioids. 
  6. Psychological or social support
10. Prognosis
  • Recovery: Depends on several factors (e.g., stenosis severity stenosis, treatment response, presence of neurological deficits, overall health). The majority of individuals with mild to moderate LSS have a favorable prognosis, but neurogenic claudication due to LSS can recur or persist.
  • Negative Prognostic Factors: Smoking, obesity, higher initial pain and disability levels, poor recovery expectations, mental health issues, persistent symptoms.
11. Ongoing Follow-up
  • Monitor progress: Reassess symptoms, functional status, and patient-reported outcomes at appropriate intervals. Confirm that care remains aligned with the patient’s goals, values, and expectations.
  • Adjust treatment plan: Continuously realign the management plan based on evolving goals, treatment response, clinical findings, and professional judgment. Modify interventions, dosage, frequency, or focus as needed to support meaningful improvement.
  • Support self-management: Reinforce the patient’s understanding of home strategies, activity recommendations, and behavioural approaches. Encourage adherence and address barriers that may affect progress.
  • Recognize plateaus or change in status: Identify when the patient is improving, stable, or worsening. Reassess for contributing factors such as comorbidities, psychosocial influences, or new functional limitations.
  • Referral and co-management: Consider referral or co-management with an appropriate provider when there is limited or no significant improvement within an expected timeframe (for example 6 to 8 weeks), when new or concerning findings emerge, or when additional expertise is required to support optimal care.
  • Documentation: Record follow-up assessments, changes to the plan, patient feedback, reassessment of goals, and any referral or co-management decisions.
12. Criteria for Discharge
  • Discharge criteria: Establish clear criteria for concluding active care. These may include achieving the patient’s initial goals, demonstrating meaningful improvement in symptoms or function, reaching a plateau in progress, or transitioning to self-management as the primary approach. Consider patient preferences, functional demands, and clinical judgment when determining readiness for discharge.
  • Clinical reassessment: Prior to discharge, complete a focused reassessment to confirm stability of symptoms, functional status, and the patient’s confidence in managing their condition. Address any remaining concerns and ensure no new issues require further evaluation.
  • Post-discharge planning: Discuss ongoing self-management strategies, including activity recommendations, home exercises, behavioural or lifestyle modifications, and symptom monitoring. Provide guidance on when to return for follow-up, when to seek additional care, and what indicators should prompt medical evaluation.
  • Future care needs: Clarify options for episodic care, preventive visits, or re-engagement with the provider if symptoms recur or functional demands change. Encourage ongoing communication if new concerns arise.
  • Documentation: Record the rationale for discharge, the patient’s status at the time of discharge, self-management recommendations provided, and the agreed-upon follow-up plan
