Its sensitivity and specificity is higher than other screening questionnaires for neuropathic pain, including the Douleur Neuropathique 4 (DN4), Leeds Assessment of Neuropathic Symptoms and Signs (LANNS), and the Neuropathic Pain Questionnaire (NPQ) (Freynhagen et al 2006). The painDETECT questionnaire has been used to identify neuropathic pain in patients with knee osteoarthritis (Ohtori et al 2012) and to identify sensory profiles in patients with diabetic neuropathy and postherpetic neuralgia (Baron et al 2009). However, further research is needed to demonstrate its clinimetric properties in these conditions. The painDETECT questionnaire,

in either the electronic or paper format, is a useful Selleck KRX 0401 tool Selleck Trametinib for clinicians, to screen for neuropathic pain in patients with low back pain and aid in patient management. Screening tools should not replace clinical judgment but can alert clinicians of neuropathic pain that may need further diagnostic evaluation. “
“The Work Instability Scale (RA-WIS) is a 23-item self-report questionnaire developed in 2003

to assess risk of work instability in people with rheumatoid arthritis (Gilworth et al 2003). Work instability was defined as a mismatch between an individual’s functional ability and his/her work tasks that place the individual at risk for work disability (lowered productivity/premature job loss, etc). Although the RA-WIS was originally developed to measure work instability in people diagnosed with rheumatoid arthritis, it has subsequently been validated for other musculoskeletal disorders (Roy Thiamine-diphosphate kinase et al 2011). It has 23 items with a dichotomous response option of yes/no, dealing with the daily demands of work. It has no subscales.

Instructions to client and scoring: Patients are asked to read the question and answer in terms of yes/no only; it is scored by counting the number of Yes responses. The total score ranges from 0 to 23 with a higher score indicating great work instability. The WIS results can be classified into three categories indicating the risk of work instability, low (less than 10), medium (10–17), and high (above 17). Clinical measurement properties: The RA-WIS has been found to be reliable,valid, and responsive in people with rheumatoid arthritis ( Gilworth et al 2003), osteoarthritis ( Tang et al 2011), and with work related upper extremity disorders ( Tang et al 2009). It has exhibited unidimensionality in both RA and OA populations ( Williams et al 2007, Roy et al 2011). Reliability: It has demonstrated high internal consistency (0.92) and test-retest reliability (0.89) in workers with arthritis ( Beaton et al 2010). Gilworth et al 2003 also found RA-WIS to exhibit excellent test-retest reliability in RA patients (Spearman’s rho = 0.89).
