Abstract
BACKGROUND:
Dynamic humeral centering (DHC) is a physiotherapy modality that aims to prevent sub-acromial impingement of rotator cuff tendons. We recently developed a new clinical manoeuver – the Viggo-Cochin test – to enhance the ability of the Neer test to detect sub-acromial impingement. Here we hypothesised whether the DHC effect may differ between individuals with positive and negative Viggo-Cochin test results.
OBJECTIVE:
To assess the association between DHC and Viggo-Cochin test results.
METHODS:
Individuals with shoulder pain due to sub-acromial impingement underwent the Neer and Viggo-Cochin tests at baseline. They were assessed before and after DHC by the Shoulder Pain and Disability Index (SPADI). A positive response to DHC was defined as a 20% reduction in the SPADI.
RESULTS:
We included 50 individuals (53 shoulders). The response to DHC did not differ by Neer test result at baseline: OR 0.73 [95% CI 0.22–2.38] (
CONCLUSIONS:
We found a higher clinical response to DHC with a positive than negative Viggo-Cochin test result at baseline in individuals with shoulder pain due to rotator cuff disease.
