Acupuncture Benefits Patients With Tennis Elbow
Earlier this year Ural et al, from Yildirim Beyazit University Medical School in Ankara, studied the effects of acupuncture on patients with lateral epicondylitis/epicondylopathy (LE). Lateral epicondylitis or tennis elbow, as it’s more commonly known, is an overuse injury that leads to pain on the lateral aspect of the elbow and/or forearm. It usually affects people aged 40 or over. Treatment can include rest, NSAIDS, bracing, physiotherapy, shockwave therapy, steroid injections, platelet-rich plasma injections, Botox injections or surgery.
Diagnostic ultrasound of the common extensor tendon (CET) in people with LE can reveal oedema, bone irregularities and increased CET thickness. Common extensor tendon thickness provides information on the severity and progress of LE.
The authors randomly split 41 patients with LE into 2 groups. The control group was advised to rest and prescribed NSAIDS, exercise and bracing. The acupuncture group received the same intervention as the control group but with acupuncture in addition. The patients were offered 10 sessions (25 min each) of acupuncture over a period of 4 weeks. Six acupoints (LI4, LI10, LI11, Lu5, SJ5 and one Ah Shi point) were used and the needles were inserted into muscle and stimulated manually to achieve deqi (needling sensation). The assessments prior to and following the course of treatment consisted of a subjective pain evaluation, pressure pain threshold testing, a function questionnaire (Duruoz Hand Index) and an ultrasound evaluation of CET thickness.
Results showed that pain and function scores improved in both groups. Whereas pain pressure thresholds and CET thickness decreased in the acupuncture group only. Improvements in pain, function, pain pressure threshold and CET thickness were significantly higher in the acupuncture group.
The authors conclude that “acupuncture treatment not only reduces pain but improves the tendon morphology in LE patients.”
