A quantitative placebo controlled study of the efficacy of manipulation of acromioclavicular joint dysfunction in weight trainers
(2009) Jordan, Warren Gray
Objective: The efficacy of manipulation as compared to placebo in the treatment of two groups of weight trainers with Acromioclavicular (AC) Joint Dysfunction. Methods: Twenty patients (n=20), using randomised sampling were allocated to two intervention groups. Patients in each group received four treatments each over a two-week period and assessed at initial, one week, two weeks and one month follow ups. Objective measures included Algometer and Inclinometer readings. Numerical Pain Rating Scales (NRS), Shoulder Rating Questionnaire (SRQ) and the Shoulder Pain and Disability Index (SPADI) measured subjective outcomes. Results: Manipulation demonstrated significant improvement in objective findings. Subjective outcomes did not show significant difference between the manipulation and placebo groups. Conclusion: Manipulation, when compared to placebo, can be considered as an effective treatment intervention for the treatment of AC joint dysfunction with particular reference to objective outcomes. Although, caution needs to be utilised in accepting this outcome due to limitations in sample size, subjective measure sensitivity and specificity as well as the stringency of the inclusion and exclusion criteria.
