Overview
Brief Summary
Chronic lateral epicondylitis is usually managed conservatively. The purpose of this single-blinded, randomized, controlled study is to compare the clinical therapeutic effects of extracorporeal shock wave therapy (ESWT) in comparison with cryoultrasound (Cryo-US) therapy in chronic lateral epicondylitis (LE) during a period of 12 months.
Detailed Description
Eighty participants with chronic LE were randomly assigned to receive 3 ESWT sessions at 48/72-hours intervals -2400 impulses at energy flux density 0.14-0.20 mJ/mm2 at each session- (ESWT Group, n=40) or 12 Cryo-US therapy sessions (4 daily sessions per week) in a continuous modality at 1.8 Watt/cm2 and -2˚C at each session- (Cryo-US Group, n=40). Visual Analogue Scale (VAS) and satisfactory results, considered as the sum of the excellent and good scores in the Roles and Maudsley score, were used as outcome measures at baseline and 3, 6, and 12 months post-treatment.

- •Acute infection of the soft tissues or the bones adjacent to the area of treatment
- •Local bleedings or skin lesions, pathologies of the blood coagulation, or use of anticoagulant drugs
- •Pacemaker, pregnancy

Outcomes
Primary Outcomes
Difference of two points in pain recorded on the VAS
Time Frame: 3, 6, or 12 months after the end of treatments
a difference of two points in pain recorded on the VAS during a maximum voluntary resisted isometric wrist extension with the elbow in extension (Cozen test), between the ESWT Group and the Cryo-US Group, in at least one of the periods taken into account.
Secondary Outcomes
- Patients satisfaction based on the Roles and Maudsley score(3, 6, or 12 months after the end of treatments)
