Sarcopenia and Interlaminar Epidural Steroid Injection Outcomes in Lumbar Spinal Stenosis
Association Between Sarcopenia and Outcomes of Interlaminar Epidural Steroid Injection in Patients With Lumbar Spinal Stenosis: A Prospective Observational Study
This prospective observational study aims to investigate the association between sarcopenia and clinical outcomes following interlaminar epidural steroid injection in patients with lumbar spinal stenosis.
Patients who are scheduled to undergo interlaminar epidural steroid injection as part of routine clinical care will be enrolled. Before the procedure, sarcopenia-related assessments, including the SARC-F questionnaire, handgrip strength, and the five-times sit-to-stand test, will be performed. Lumbar magnetic resonance imaging (MRI) will also be evaluated for paraspinal muscle characteristics and the severity of lumbar spinal stenosis.
Pain intensity, functional status, walking capacity, and health-related quality of life will be assessed at baseline. Pain intensity, functional status, and health-related quality of life will be reassessed at 3 weeks and 3 months after the procedure. The study will evaluate whether sarcopenia and MRI-based paraspinal muscle characteristics are associated with clinical outcomes following interlaminar epidural steroid injection.

The study population will consist of patients aged 50-75 years with clinically and radiologically diagnosed lumbar spinal stenosis who are scheduled to undergo interlaminar epidural steroid injection as part of routine clinical care due to persistent symptoms despite conservative treatment. Participants will be classified according to sarcopenia status based on baseline assessments and followed for 3 months.

Patients with Sarcopenia
Patients with lumbar spinal stenosis who meet the European Working Group on Sarcopenia in Older People 2 (EWGSOP2) criteria for probable sarcopenia based on reduced muscle strength at baseline and who are scheduled to undergo interlaminar epidural steroid injection as part of routine clinical care. |
|
Patients without Sarcopenia
Patients with lumbar spinal stenosis who do not meet the European Working Group on Sarcopenia in Older People 2 (EWGSOP2) criteria for probable sarcopenia based on muscle strength assessment at baseline and who are scheduled to undergo interlaminar epidural steroid injection as part of routine clinical care. |

Change in Leg Pain Following Interlaminar Epidural Steroid Injection by Sarcopenia Status
기간: Baseline, 3 weeks, and 3 months
|
Leg pain intensity will be assessed using the Numeric Rating Scale (NRS), ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain. NRS scores will be recorded at baseline, 3 weeks, and 3 months. Changes in leg pain intensity from baseline will be compared between patients with and without sarcopenia. |

Change in Low Back Pain Following Interlaminar Epidural Steroid Injection by Sarcopenia Status
기간: Baseline, 3 weeks, and 3 months
|
Low back pain intensity will be assessed using the Numeric Rating Scale (NRS), ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain. NRS scores will be recorded at baseline, 3 weeks, and 3 months. Changes in low back pain intensity from baseline will be compared between patients with and without sarcopenia. |

Change in Functional Disability Following Interlaminar Epidural Steroid Injection by Sarcopenia Status
기간: Baseline, 3 weeks, and 3 months
|
Functional disability will be assessed using the Istanbul Low Back Pain Disability Index (ILBPDI). The ILBPDI consists of 18 items and has a total score ranging from 0 to 90, with higher scores indicating greater disability. ILBPDI scores will be recorded at baseline, 3 weeks, and 3 months. Changes from baseline will be compared between patients with and without sarcopenia. |

Change in Health-Related Quality of Life Following Interlaminar Epidural Steroid Injection by Sarcopenia Status
기간: Baseline, 3 weeks, and 3 months
|
Health-related quality of life will be assessed using the 12-Item Short Form Health Survey (SF-12), which provides Physical Component Summary (PCS) and Mental Component Summary (MCS) scores. Both scores range from 0 to 100, with higher scores indicating better health-related quality of life. Scores will be recorded at baseline, 3 weeks, and 3 months. Changes from baseline will be compared between patients with and without sarcopenia. |

Correlation Between Erector Spinae Cross-Sectional Area and Leg Pain Outcome
기간: Baseline Magnetic Resonance Imaging; leg pain at baseline, 3 weeks and 3 months
|
Erector spinae cross-sectional area (CSA) will be measured on baseline lumbar magnetic resonance imaging (MRI) in square centimeters (cm²). Leg pain intensity will be assessed using the Numeric Rating Scale (NRS), ranging from 0 to 10, with higher scores indicating greater pain intensity. The correlation between baseline erector spinae CSA and change in leg pain NRS from baseline will be evaluated. |
