Acupuncture for acute musculoskeletal pain in the emergency department and clinic: a pragmatic randomized trial.

Researchers at an academic emergency department studied whether acupuncture could help patients with sudden-onset musculoskeletal pain in the neck, back, or limbs. The study enrolled 599 adults who had experienced pain for seven days or less, comparing those receiving usual care alone to those receiving acupuncture treatments plus usual care.

Participants in the acupuncture group received their first treatment in the emergency department from licensed acupuncturists, followed by twice-weekly sessions at a clinic for one month. Both groups started with similar pain levels, averaging 7.1 out of 10. After one month, the overall results showed both groups had improved to similar pain levels—3.8 for usual care and 3.2 for acupuncture.

However, the study revealed an important finding: nearly half of the acupuncture participants couldn't attend the follow-up clinic sessions due to time and financial barriers. When researchers looked more closely at those who attended six or more acupuncture sessions (about 20% of participants), these patients experienced significantly greater pain improvement compared to those who attended fewer sessions.

What this means for patients: Acupuncture may be effective for acute musculoskeletal pain, but success appears to depend heavily on consistent treatment attendance. The study suggests that six or more sessions may be necessary to achieve meaningful pain relief. Barriers like cost, time off work, and transportation can prevent people from completing a full course of treatment, which may limit acupuncture's effectiveness. If you're considering acupuncture for acute pain, find a qualified, licensed acupuncturist and plan for multiple treatment sessions to achieve the best results.

This pragmatic randomized controlled trial enrolled 599 ED patients with acute musculoskeletal pain (≤7 days duration) in the neck, back, or extremities. Participants were randomized to usual care (n=189) or acupuncture plus usual care (n=410), with acupuncture delivered initially in the ED and then twice weekly for one month by licensed acupuncturists. Baseline pain scores were similar (7.1/10 in both groups). Intention-to-treat analysis showed no significant difference at one month (control 3.8 vs. acupuncture 3.2). However, 43.4% of acupuncture participants couldn't attend clinic sessions due to time and financial constraints. Exploratory analysis revealed patients completing ≥6 sessions (n=121, 20.2%) achieved significantly greater pain reduction compared to those with fewer sessions. Clinical takeaway: Acupuncture efficacy for acute musculoskeletal pain appears dose-dependent, with six or more sessions needed for optimal outcomes. Access barriers significantly limited treatment adherence and potentially masked treatment benefits in intention-to-treat analysis.
