Acupuncture for Chronic Low Back Pain in Older Adults: A Randomized Clinical Trial.

The short version

This randomized trial with 800 participants asked a question no large study had answered: does acupuncture help adults 65 and older with chronic low back pain? Acupuncture — the Traditional Chinese Medicine practice of inserting fine needles at specific points — is already guideline-recommended for back pain in general adults, but older adults face the highest risks from pain medications and had never had a dedicated large trial. The results were designed to inform Medicare coverage. Participants (average age 74, and 41% over 75) were randomized to three groups: standard acupuncture (8–15 sessions over 12 weeks), enhanced acupuncture (the same plus 4–6 maintenance sessions), or usual medical care alone. Real-world community acupuncturists — more than 50 of them — tailored needling to each patient, and disability was measured with the Roland-Morris questionnaire, a standard count of daily activities limited by back pain. At six months, both acupuncture groups functioned meaningfully better than usual care. The share of people achieving at least 30% improvement — the accepted bar for a clinically meaningful change — was 43.8% with enhanced acupuncture and 39.1% with standard, versus 29.4% with usual care alone (a relative 49% and 33% higher chance of meaningful improvement). Benefits held at twelve months. Pain intensity and anxiety also improved, and maintenance sessions added a modest edge on pain. Safety was excellent: serious adverse events were rare, equal across groups, and less than 1% were possibly related to acupuncture. For older adults weighing pain options, this is the strongest evidence yet: acupuncture delivered by community practitioners produced lasting improvement with almost no risk — in a population where the usual alternatives (opioids, NSAIDs, gabapentinoids) carry their highest dangers. The authors suggest it may deserve first-line status for this age group.

Key findings

• This was the first large randomized trial of acupuncture specifically in adults 65 and older with chronic low back pain, designed to inform Medicare coverage.
• At six months, 43.8% of the enhanced-acupuncture group and 39.1% of the standard group achieved clinically meaningful improvement (at least 30% less disability), versus 29.4% with usual care alone.
• Benefits persisted at twelve months, and anxiety symptoms also improved alongside pain and function.
• Maintenance sessions (4–6 extra over three months) added a modest edge on pain intensity but not on the primary disability outcome.
• Serious adverse events were rare and equally distributed, with less than 1% possibly related to acupuncture — a key contrast with opioids, NSAIDs, and gabapentinoids in this age group.
