Chronic lateral epicondylitis of the elbow: A prospective study of low-energy shockwave therapy and low-energy shockwave therapy plus manual therapy of the cervical spine

Abstract

Rompe JD, Riedel C, Betz U, Fink C. Chronic lateral epicondylitis of the elbow: a prospective study of low-energy shockwave therapy and low-energy shockwave therapy plus manual therapy of the cervical spine. Arch Phys Med Rehabil 2001;82:578-82. Objective: To compare the effects of extracorporeal shockwave therapy (ESWT) alone with a combination of ESWT and manual therapy of the cervical spine in treating chronic tennis elbow. Design: Prospective, matched single-blind control trial. Setting: University hospital clinic. Patients: Thirty patients with unilateral chronic tennis elbow, an unsuccessful conservative therapy during the 6 months before referral, and clinical signs of cervical dysfunction (eg, pressure pain at the C4-5 and/or C5-6 level, protraction of the head). Interventions: Three times at weekly intervals all patients received 1000 shockwave impulses of an energy flux density of.16mJ/mm2 at the lateral elbow. Additionally, they underwent manual therapy of the cervical spine and the cervicothoracic junction 10 times (group I). For each patient, a control matched by age (3-yr range) and gender at first conservative treatment was drawn at random from 127 patients who had undergone low-energy shockwave therapy in the same unit in the past 3 years (group II). Follow-up examinations took place at 12 weeks and at 12 months. Main Outcome Measures: The Roles and Maudsley outcome score at 12 months, defining an excellent or good result with no or only occasional discomfort without limitation of activity and range of motion. Results: Neither group differed statistically before the study, with a poor rating for all patients (p >.05). At 12 months, there was still no significant difference, with the outcome being excellent or good in 56% in group I, and in 60% in group II (p >.05). Each group showed significant improvement compared with the respective prestudy evaluation (p <.0001). Conclusion: ESWT may be an effective conservative treatment method for unilateral chronic tennis elbow. The efficacy of additional cervical manual therapy for lateral epicondylitis remains questionable. © 2001 by the American Congress of Rehabilitation Medicine and the American Academy of Physical Medicine and Rehabilitation
