Brief Summary
This will be a prospective cohort observational study observing patients with low back pain with leg pain who present for outpatient physical therapy care at Rusk Rehabilitation at NYU Langone Ambulatory Care Lake Success. Patients are eligible if they present with imaging of stenosis in their lumbar spine on MRI or CT Scan and note radicular leg symptoms with associated neurological deficits on the physical examination for at least 12 weeks.

Outcome Measures
Primary Outcomes (2)
Prevalence of directional preference (DP) among patients diagnosed with lumbar spinal stenosis (LSS)
Prevalence is calculated as the proportion of patients with DP out of the total sample of LSS patients.
Baseline

Prevalence is calculated as the proportion of patients with DP out of the total sample of LSS patients.

Study Arms (1)
Lumbar stenosis patients
Patients undergoing physical therapy treatment at an outpatient clinic will be enrolled. Data collection will include patient outcome measures, if directional preference is present and results from the functional tests performed by 3 licensed physical therapists who also hold their diploma in the McKenzie Method of Mechanical Diagnosis and Therapy (specialized training in recognizing directional preference) as a part of routine care (not research) for the enrolled patients. Data will be collected at initial onset, at discharge, and at a 6 months follow up.
Eligibility Criteria
All patients that choose to participate are undergoing a course of outpatient physical therapy care on their own accord with a referral to physical therapy. The participants have the ability to drop out or withdraw at any point of the study.
You may qualify if:
- Neurogenic claudication (pain in the buttock, thigh, or leg during ambulation) or radicular leg symptoms with associated neurological deficits on the physical examination for at least 12 weeks.
- Confirmatory cross-sectional magnetic resonance imaging (MRI) or computed tomography (CT) imaging demonstrating the presence of either central or lateral lumbar spinal stenosis at one or more levels was required.
- Age \>48 years old
- Willing and able to consent
- Scheduled to receive physical therapy that includes the collection of patients outcomes, functional tests, and may include the conduct of a two-stage treadmill test
You may not qualify if:
- Radiographic evidence of instability, degenerative spondylolisthesis, fracture, or scoliosis of more than 15°.
- Comorbid health conditions precluding surgical management, prior lumbar surgery, progressive neurological deficit, any inflammatory conditions such as rheumatoid arthritis or indication of a potential non-musculoskeletal spinal condition (e.g., active malignancy, infection, etc.)
