About

This clinical trial aims to investigate the intra- and inter-rater reliability of pain pressure threshold algometry in lateral epicondylitis patients.

Full description

Tennis elbow, also known as lateral epicondylitis (or epicondylosis) of the elbow, was first described at the end of the 19th century. The community prevalence is 1% to 3%,38 with an even sex distribution and a peak incidence between 35 and 55 years of age.16 There is consensus that the mechanism of injury involves repetitive loads at the wrist and elbow, including supination and extension of the wrist.15 People affected by tennis elbow commonly have pain over the lateral humeral epicondyle, with flexion at the elbow also usually limited by pain, especially if the wrist is pronated and extended against resistance.

Assessment of reliability is a necessary first step in the validation procedures of clinical tests. The reliability of the PPT measurement is susceptible to the influence of rater behavior and judgment, such as the instructions to the participant, rate of force application, and reaction time of the rater.

We opted to investigate the intra- and inter-rater reliability of PPT in persons with lateral epicondylitis with three raters, rater blinding, and a pause of ≥20 seconds between each measurement. We hypothesized that clinicians with no former experience with the procedure can master it with good reliability after a single 30-min training session.
