Validity and Reliability of the 2-minute Step Test in Patients With Lumbar Spinal Stenosis

Study Overview
=================
Brief Summary
-----------------
The aim of this study was to investigate the validity and reliability of the 2 Minute Step Test (2MST) in patients with symptomatic degenerative lumbar spinal stenosis and to explore its correlation with objective assessment methods, namely the 2 Minute Walk Test (2MWT) and the 6 Minute Walk Test (6MWT).

Detailed Description
-----------------
This cross-sectional study will include 55 volunteers aged 18-80 years who present to the Istanbul Physical Medicine and Rehabilitation Training and Research Hospital outpatient clinics and are diagnosed with Lumbar Spinal Stenosis (LSS) through MRI. The demographic characteristics of the patients will be recorded, and their walking distances will be inquired about. The severity of the disease will be determined by examining the levels of stenosis on lumbar MRI scans. All patients will be initially assessed using the 2MST (2-Minute Step Test), 2MWT (2-Minute Walk Test), 6MWT (6-Minute Walk Test), VAS (Visual Analogue Scale), and ODI (Oswestry Disability Index). To measure test-retest reliability, the 2MST will be administered again with a 7-day interval between assessments.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 2-minute step test | The patient was instructed to lift their knees to the minimum marked level and take as many steps as possible in place for a duration of two minutes. | Baseline and Day 7 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 6-minute walk test | The distance the patient walked for six minutes was measured. | Baseline and Day 7 | 
| 2-minute walk test | The distance the patient walked for two minutes was measured. | Baseline and Day 7 | 
| Oswestry Disability Index | This is a patient-reported outcome measure used by clinicians and researchers to quantify disability related to low back pain: Higher scores indicate worse functional status. | Baseline and Day 7 | 
| Visual Analogue Scale | Pain score; higher scores indicate higher pain levels. | Baseline and Day 7 |
