Background summary
At the VU medical centre a postoperative shoulder rehabilitation guideline has
been developed regarding 4 types of shoulder surgeries.
* stabilizing shoulder operations e.g. Bankart repair or capsular shift
* rotator cuff repair
* acromion arthroplasty or lateral clavicula resection
* hemi- or total glenohumeral arthroplasty
To provide high-quality rehabilitation, the instruments used need to be of
high psychometric quality. Additionally, these instruments should cover all
domains of the International Classification of Function (ICF, 2001).
The training of scapular stability is regularly applied. Therefore, there is a
need for a clinical diagnostic and evaluating instrument to measure scapular
function. Burkhart (Burkhart, 2003) describes within *the scapular rating
scale* a classification of 3 scapular malpositions. This provides a practical
clinical instrument to diagnose the function of the scapula. However, no
psychometric qualities of this specific *scapula position test* have been
described.
Furthermore, there is a need for disease specific questionnaires. The
University of Western Ontario in Canada developed 3 disease specific
questionnaires, the so called *Shoulder Index Questionnaires*. One
questionnaire for rotator cuff diseases (WORC), one for shoulder instability
(WOSI) and one for shoulder osteoarthritis (WOOS). Each of these
questionnaires demonstrate good psychometric qualities. However, there is no
Dutch language version available.
Study objective
To determine the reproducibility and responsiveness of the Scapula Position
Test and the WORC, WOSI and WOOS questionnaires in patients with shoulder
symptoms.
Study design
150 patients are included in this study and examined at 3 different
timepoints, 2 measurements pre-operatively and 1 measurement post-operatively.
Every measurement session takes 15 minutes. Two independent raters score the
scapular position test. Finally the disease specific questionniare (WORC, WOSI
or WOOS) is filled out by the patient.
The inter-rater and intra-rater reliability of these instruments is determined
by calculating the Interclass Correlation Coefficient (ICC). Absolute agreement
ICC*s and minimal detectable differences (MDD) will be calculated (two way
mixed model with measures of absolute agreement). Responisveness is determined
by calculating Guyatt*s responsiveness ratio. Additionally, to assess
responsiveness ROC curves will be made.
Study burden and risks
not applicable (the scapula is observed and the position is recorded). Filling
in a questionnaire does not give any risk.
