Back Pain from Sitting in an Office Chair

Back pain from sitting in an office chair can be alleviated through adjusting posture, taking regular breaks, choosing the right office chair, and using medication.

1. Adjusting Posture
Maintaining the natural curvature of the lumbar spine is crucial. Choose a chair with a backrest and use a soft cushion or ergonomic lumbar support to keep the lumbar region supported and prevent it from hanging in the air. Keep your feet flat on the ground with your knees and hips at a 90-degree angle to prevent posterior or anterior pelvic tilt. Adjust the chair height so that your elbows are naturally at the same level as the desk when hanging down, avoiding arm suspension or excessive forward reach. Adjust your posture slightly every 30 minutes, such as straightening your back or leaning back slightly, to prevent muscle fatigue from maintaining the same position for too long.

2. Taking Regular Breaks
Sitting continuously for more than 1 hour can cause poor blood circulation in the lower back and increase pressure on the intervertebral discs. It is recommended to get up and move for 3-5 minutes every hour, performing gentle movements such as waist rotation, lateral bending, or backward bending to promote local blood circulation. You can also stand against a wall (with the back of your head, shoulder blades, buttocks, and heels touching the wall) or take a walk to reduce the load on the lumbar spine. Avoid sudden twisting of the waist to prevent disc injury.

3. Choosing the Right Office Chair
Some ergonomic chairs have design flaws, such as overly soft cushions that cause the buttocks to sink and the lumbar spine to hang in the air, or improperly positioned lumbar supports that fail to support the lumbar spine. When purchasing, pay attention to the following:

• Cushion Adjustability: Choose a cushion that is moderately firm and can adjust its support based on body weight to prevent numbness in the buttocks or excessive lumbar lordosis.
• Lumbar Support Fit: The lumbar support should be adjustable up and down and forward and backward to ensure it supports the 3rd to 5th lumbar vertebrae (the most concave part of the waist).
• Backrest Curvature: The backrest should conform to the natural curve of the spine, providing overall support rather than just localized pressure.

4. Other Relief Methods
If the pain is significant, treatment should be based on the cause:

• Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): Such as diclofenac sodium sustained-release tablets and celecoxib capsules, which can be taken orally to relieve inflammatory pain.
• Topical Medications: Flurbiprofen gel patches are absorbed through the skin, reducing gastrointestinal side effects.
• Muscle Relaxants: Eperisone hydrochloride tablets are suitable for those with muscle spasms and should be used under medical advice.
• Anti-Osteoporosis Drugs: Such as alendronate sodium tablets, which are suitable for back pain caused by osteoporosis and should be used in combination with calcium and vitamin D.

Long-term prevention requires incorporating daily habits, such as controlling weight, strengthening core muscle exercises (such as planks and swimming), avoiding prolonged sitting or standing, and reducing the load on the lumbar spine from the root. If there is no improvement after adjustments, it is recommended to seek medical attention promptly to rule out organic diseases such as intervertebral disc herniation and lumbar spinal stenosis.
