PURPOSE: To identify the ability of the Persian-version of the Shoulder Pain and
Disability Index (SPADI) and the Disabilities of the Arm, Shoulder, and Hand
(DASH) to detect changes in shoulder function following physiotherapy
intervention (i.e. responsiveness) and to determine the change score that
indicates a meaningful change in functional ability of the patient (i.e.
Minimally Clinically Important Difference (MCID)). METHOD:
A convenient sample of
200 Persian-speaking patients with shoulder disorders completed the SPADI and the
DASH at baseline and then again 4 weeks after physiotherapy intervention.
Furthermore, patients were asked to rate their global rating of shoulder function
at follow-up. The responsiveness was evaluated using two methods: the receiver
operating characteristics (ROC) method and the correlation analysis. Two useful
statistics extracted from the ROC method are the area under curve (AUC) and the
optimal cutoff point called as MCID. RESULTS: Both the SPADI and the DASH showed
the AUC of greater than 0.70 (AUC ranges = 0.77-0.82). The best cutoff points (or
change scores) for the SPADI-total, SPADI-pain, SPADI-disability and the DASH
were 14.88, 26.36, 23.86, and 25.41, respectively. Additionally, moderate to good
correlations (Gamma = -0.51 to -0.58) were found between the changes in
SPADI/DASH and changes in global rating scale. CONCLUSIONS:
The Persian SPADI and
DASH have adequate responsiveness to clinical changes in patients with shoulder
disorders. Moreover, the MCIDs obtained in this study will help the clinicians
and researchers to determine if a Persian-speaking patient with shoulder disorder
has experienced a true change following a physiotherapy intervention.
Implications for Rehabilitation Responsiveness was evaluated using two methods;
the receiver operating characteristics (ROC) method and the correlation analysis.
The Persian SPADI and DASH can be used as two responsive instruments in both
clinical practice and research settings. The MCIDs of 14.88 and 25.41 points
obtained for the SPADI-total and DASH indicated that the change scores of at
least 14.88 points on the SPADI-total and 25.41 points on the DASH is necessary
to certain that a true change has occurred following a physiotherapy intervention.
