Lateral elbow tendinopathy: surgery versus extracorporeal shock wave therapy

Percutaneous tendon dry needling and thrust manipulation as an adjunct to multimodal physical therapy in patients with lateral elbow tendinopathy: A multicenter randomized clinical trial

OBJECTIVE

The purpose of this study was to assess the effects of adding electrical dry needling and thrust manipulation into a multimodal program of exercise, mobilization, and ultrasound in patients with lateral elbow tendinopathy.

DESIGN

Randomized, single-blinded, multicenter, parallel-group trial.

SETTING

Thirteen outpatient physical therapy clinics in nine different US states.

PARTICIPANTS

One hundred and forty-three participants (n = 143) with lateral elbow tendinopathy were randomized.

INTERVENTION

Cervical spine manipulation, extremity manipulation, and percutaneous tendon electrical dry needling plus multimodal physical therapy (n = 73) or multimodal physical therapy (n = 70) alone.

MAIN MEASURES

The primary outcome was elbow pain intensity and disability as measured by the Patient-Rated Tennis Elbow Evaluation at baseline, 1 week, 4 weeks, and 3 months. Secondary outcomes included the Numeric Pain Rating Scale, Tennis Elbow Functional Scale, Global Rating of Change, and medication intake.

RESULTS

The 2 × 4 analysis of covariance demonstrated that individuals with lateral elbow tendinopathy receiving electrical dry needling and thrust manipulation plus multimodal physical therapy experienced significantly greater improvements in disability (Patient-Rated Tennis Elbow Evaluation: F = 19.675; P < 0.001), elbow pain intensity (Numeric Pain Rating Scale: F = 22.769; P < 0.001), and function (Tennis Elbow Function Scale: F = 13.269; P < 0.001) than those receiving multimodal physical therapy alone at 3 months. The between-group effect size was large for pain and disability (Patient-Rated Tennis Elbow Evaluation: standardized mean difference = 1.13; 95% confidence interval: 0.78, 1.48) in favor of the electrical dry needling and thrust manipulation group.

CONCLUSIONS

The inclusion of percutaneous tendon electrical dry needling and thrust manipulation into a multimodal program of exercise, mobilization and ultrasound was more effective than multimodal physical therapy alone in individuals with lateral elbow tendinopathy.Trial Registration: www.clinicaltrials.gov NCT03167710 May 30, 2017.

Effectiveness of extracorporeal shockwave therapy in treatment of upper and lower limb tendinopathies: A systematic review and meta-analysis

BACKGROUND

Tendinopathy is caused by repetitive motion, excessive stress on the tendon, overstretch, and motion past the critical angle of rotation or translation. There are various treatment options available for tendinitis, including those affecting both the upper and lower limbs and those of calcific and non-calcific types.

HYPOTHESIS/PURPOSE

Few reviews have analyzed the efficacy of Extracorporeal Shockwave Therapy (ESWT) in treating upper and lower limb tendinopathies while considering calcific and non-calcific-type tendinitis. This paper provides a review and meta-analysis on Randomized Controlled Trials (RCTs), which compared results from a group undergoing ESWT treatment to another group under different treatments.

STUDY DESIGN

Systematic review and meta-analysis.

METHODS

A systematic search was conducted on PubMed, Web of Science, Embase, the Cochrane Central Register of Control Trials (CENTRAL), and Physiotherapy Evidence Database (PEDro) databases for articles published up to January 2022. The reference lists of identified articles were further scanned. Twenty-two studies were included in the meta-analysis.

RESULTS

Meta-analysis showed no difference in pain reduction in ESWT when compared with a comparison group at 4 (p = 0.26) and 12 weeks (p = 0.33). There were no differences in DASH scores at 12 months between the two groups (p = 0.32).

CONCLUSION

Extracorporeal Shockwave Therapy (ESWT) is effective when used to treat lower limb and calcific tendinitis. It does not yield any better results than other treatment options in managing upper limb tendinopathies and non-calcific tendinopathies.

[Treatment of lateral and medial epicondylopathy : Are platelet-rich plasma, shock wave therapy, etc. effective for both?]

Lateral and medial epicondylopathy (epicondylitis), which are common and in most cases self-limiting, frequently result in relevant reduction of quality of life and may also affect the ability to work. Recently, the use of orthobiologics, such as platelet-rich plasma (PRP), has been proposed to promote tendon regeneration and is supposed to be a valuable treatment option. However, scientific data are conflicting and the short- and long-time results are controversial. The use of stem cells is new approach and preliminary clinical data are promising. Shock wave therapy is widely used and part of the daily routine in treating lateral epicondylopoathy, although it is questionable for medial epicondylopathy.

Application of shock wave therapy in the treatment of calcific tendinopathies

Tendons are the soft tissue that connects muscles to bones. They are made of collagen and elastin, they are strong and solid, and have no possibility of contraction. Their strength helps us to move. Recovery of tendon injuries is long-lasting and can take more than six months. If a tendon is shed during a time injury, calcification occurs at the site of the injury and the disease is called calcifying tendinopathy. The very existence of calcifications is an indication for treatment with a mechanical shock wave (Shock wave). Mechanical shock waves can act in focus or radially. The difference between focused and radial waves is primarily in their physical basis. Focused shock waves differ from radial shock waves in terms of therapeutic depth of penetration into the tissue. The basic biological effect of a mechanical shock wave is stimulating. The energy of the mechanical shock wave acts at the cellular level by stimulating the reduction of inflammation and pain in the tissue. Using mechanical shock wave in the treatment of calcified tendinopathies, a safe method for breaking calcifications was obtained. Shock wave can be applied to using: different frequency, different number of strokes, as well as different strength of strokes in their studies. The choice of parameters for the application depends on whether it is calcified or non-calcified tendinopathy. Indications for the use are: painful shoulder, heel spur, plantar fasciitis, tennis elbow, Achilles tendon tendinopathy, jumping knee, patellar tendinitis, myalgia, myogelosis and muscular tendon overstrain syndrome. Contraindications for the use are: the existence of prostheses, knees and hips, as well as various orthopedic material, pacemaker, as well as the presence of chronic diseases such as multiple sclerosis, amyotrophic lateral sclerosis or tumors. The application of a mechanical shock wave is new, non-invasive method, easy to apply, always reduces pain and practically without side effects. This method has a special role in the treatment of chronic inflammation of diseased tendons, with or without calcification. The only dilemma in the application of a mechanical shock wave can be in the number of applications as well as the time break between the applications of two consecutive mechanical shock waves therapy.
