Physical therapy, corticosteroid injection, and extracorporeal shock wave treatment in lateral epicondylitis. Clinical and ultrasonographical comparison
OrthoEvidence Journal (OE Journal) - ACE Report
OE Journal. 2013;1(1):30 Clin Rheumatol. 2012 May;31(5):807-12. doi: 10.1007/s10067-012-1939-y. Epub 2012 Jan 2759 patients diagnosed with the condition lateral epicondylitis (LE), were randomised into three groups to undergo either physical therapy, a single corticosteroid injection, or extracorporeal shock wave treatment (ESWT), to determine which technique was the most effective in treating LE. Following assessments measured over 6 months, results displayed that all three methods used for LE treatment had positive outcomes regarding reduction in pain and an increase in grip strength in early stages. However, there were no differences in thickness and cortical abnormalities of the common extensor tendon and bony cortex of the lateral epicondyle, measured using the ultrasonography, prior to and 6 months after treatment.

Fragility Indexは、重要な所見の解釈を助けるツールで、結果の強さの尺度を提供します。Fragility Indexは、その所見が有意でなくなるために、二項対立の結果に追加する必要がある連続した事象の数を表します。数値が小さいほど弱い所見を表し、数値が大きいほど強い所見を表します。
なぜ今この研究が必要なのですか?
The most common condition associated with elbow pain is lateral epicondylitis (LE). LE results from the overuse of an injured extensor tendon of the dominant upper extremity. The condition is commonly treated through deep tendon friction massage, mobilization, physiotherapy exercises, stretching and strengthening exercises, splints, and local corticosteroid injections. Recently, shockwave therapy and Cyriax therapy have also been suggested to alleviate pain caused by LE. However, in the few comparisons that have been made between treatment types, the results have been conflicting. Hence, this study aimed to determine which of the treatment methods is more efficient in treating LE, through the clinical and ultrasonographic comparison of therapeutic effects.
主な研究課題は何ですか?
Were there any significant differences in outcomes between physical therapy, corticosteroid injection, and ESWT in patients with LE when compared clinically versus ultrasonographically, when measured over a 6 month period?
重要な知見は?
- Clinical findings indicated that there was a significant decrease in VAS scores for all three groups at months 1, 3, and 6 following treatment (p<0.001). VAS scores were similar for all three groups.
- Clinical results showed there was a significant increase in grip strength values on months 1 and 3 of treatment for Group I (Physiotherapy Group), month 1 for Group II (Injection Group), and months 1, 3, and 6 for Group III (ESWT Group) (Month 1, p<0.003; Months 3 and 6, p<0.001).
- However, ultrasonographic findings did not correlate with the results regarding improvement in pain scores and grip strength.
- There was no significant difference in pinch strength values between the three groups (p>0.05).
- There was no significant difference in the cortical irregularities of the extensor tendon prior to treatment and at 6 months of treatment for all three groups (p>0.05).
最も覚えておくべきことは?
The clinical findings demonstrated similar reductions in pain, increases in grip strength and finger pinch strength in early stages of LE treatment with physical therapy, corticosteroid injection, and ESWT. However, these changes observed clinically were not supported ultrasonographically. Rather, no differences in thickness and cortical abnormalities of the common extensor tendon and bony cortex of the lateral epicondyle were seen when measured prior and 6 months after treatment.
それが私の患者ケアにどのように影響するか?
Since clinical effects of the LE treatment were not supported ultrasonographically, confusion remains in what the long term effects of physical therapy, corticosteroid injection, and ESWT are. In future studies patients should be blinded in order to lower the potential risk of bias, the population size should be increased, and longer follow-up periods should be used.
