Simplifying the assessment of activity limitations of patients with Complex Regional Pain Syndrome 1 of the upper extremity by using the Visual Analogue Scale


Brunner, F; Hilfiker, R; Meier, B; Bachmann, L M (2011). Simplifying the assessment of activity limitations of patients with Complex Regional Pain Syndrome 1 of the upper extremity by using the Visual Analogue Scale. Journal of Musculoskeletal Pain, 19(4):207-211.

Abstract

Objective:
Instruments such as the Radboud Skills Questionnaire [RASQ] and the Disability of Arm Shoulder and Hand Questionnaire [DASH] are not commonly used in general practice because they take too much time to complete. By assessing the concurrent validity, we examined whether the Visual Analog Scale [VAS] could serve as an alternative simple proxy to measure functional limitations in patients suffering from complex regional pain syndrome 1 [CRPS 1] of the upper extremities.


Methods:
We asked patients afflicted with CRPS 1 of the upper extremities to indicate their functional limitations on the VAS and assessed the concurrent validity by comparing the results with the scores from the RASQ and the DASH.


Results:
Fifty-seven patients [37 females] with a median disease duration of 1.9 years [interquartile ranges 0.9–4.3] were included. Self-perceived activity limitations on the VAS were 5.4 ± 2.2. Average score for the RASQ was 140.1 ± 39.2 and for the DASH 64.3 ± 17.3. We found a good correlation between the VAS and the RASQ [R2 = 0.57], and the DASH [R2 = 0.64].


Conclusions:
The VAS may serve as a simple proxy to assess functional limitations in patients suffering from CRPS 1 of the upper extremities. However, it may only be used as an add-on to valid instruments in clinical practice and should not replace established and validated assessments.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
