Electroacupuncture for Trigger Finger: A Case Report

This case report describes a 58-year-old man with trigger finger—a painful hand condition causing finger locking. The study tested whether electroacupuncture could reduce his symptoms.

📋 Study design

The report follows one patient: a 58-year-old man with over a year of trigger finger in his left ring finger, including locking that required manual reduction.

He received four electroacupuncture treatments over about 1.5 months. Needles were placed around the affected tendon area, delivering 10 Hz electrical stimulation for 45 minutes per session.

The study measured nodule size, triggering frequency, locking frequency, and pain severity before and after treatment.

📊 Key findings

• Locking frequency and pain severity decreased by 50% after the first treatment.
• Further reductions in locking, pain, and nodule size occurred after each subsequent treatment.
• After the fourth treatment, the patient reported 100% resolution of symptoms with no pain or triggering.
• He continued his usual activities throughout the study period.
• No adverse events were reported.

✅ Study vs. claim

The study tested whether electroacupuncture could reduce trigger finger symptoms in one patient. It does not claim that electroacupuncture is a proven treatment for all cases of trigger finger.

The results are promising but come from one person, so they cannot be generalized.

🧪 Evidence level

A case report in a single human patient.

⚠️ What it does NOT show

• It does not show that electroacupuncture works for other people with trigger finger.
• It does not establish long-term effectiveness or safety beyond the study period.
• It does not compare electroacupuncture to standard treatments like splinting or injections.

📈 Confidence indicator

Confidence: Moderate — based on one patient, so results are not broadly reliable.

🔍 How much to trust it

The trust tier is Moderate. This means the findings should be treated with healthy caution because they come from a single case, not a controlled trial.

🚧 Limitations

• Only one patient was studied.
• No control group for comparison.
• Results may not apply to other people or other types of trigger finger.
• Long-term follow-up was not reported.

❓ Open questions

• Would electroacupuncture work in a larger group of patients?
• How does it compare to standard treatments?
• Are the effects lasting beyond the treatment period?

📝 Your action plan

• ✅ Understand that this is a single case, not proof of effectiveness.
• ✅ If you have trigger finger, discuss all treatment options with a qualified healthcare professional.
• ✅ Do not attempt electroacupuncture without professional guidance.
• ✅ Follow up with a doctor if symptoms persist or worsen.

🎯 Takeaway

Electroacupuncture resolved trigger finger symptoms in one patient, but this does not mean it works for everyone.
