Lower Back Pain: Why Prolonged Rest Is No Longer Recommended

For decades, “bed rest” was advised for low-back pain. We now know prolonged rest often delays recovery: it deconditions muscle, increases fear of movement, and does not treat the mechanical or sensory drivers of pain.

What current evidence says

For most nonspecific low-back pain (without serious neurological red flags), gradual movement, pain education, and dosed therapeutic exercise are the foundation of non-pharmacological care. The goal is not to “push through at all costs,” but to rebuild confidence and muscle control with a safe progression.

That does not mean ignoring intense acute pain: the first hours may need symptom relief and a pause from high-impact activity. The key is not turning that pause into weeks of immobility.

When urgent evaluation is needed

Seek care promptly if there is:

• Leg weakness, foot drop, or difficulty walking.
• Sphincter change or saddle anaesthesia.
• Fever, major trauma, cancer history, immunosuppression, or progressive night pain.
• Pain that steadily worsens despite initial measures.

Those signs are not “worked out at the gym”: they need medical assessment and imaging when indicated.

What physiatry does

Physical medicine and rehabilitation assesses pain pattern, mobility, strength, motor control, and work or sport factors. It may prescribe:

• Individualised therapeutic exercise (mobility, stabilisation, strength).
• Ergonomic and spinal hygiene education.
• Pain management (including electrodiagnostic studies when radiculopathy or neuropathy is suspected).
• Progression back to work or sport.

A generic “do planks and yoga” plan does not replace a prescription matched to your capacity and diagnosis.

Habits that help (and do not replace a doctor)

Keep short frequent walks, change posture at work, organise load when lifting, and sleep in a position that does not increase pain. Avoid extreme cycling or maximal lifts on the day of a flare if you have not been evaluated yet.
