“…A high score indicates a high degree of impairment [10]. The official German translation has shown to be a reliable measure [12,13] and can be used for patients with WAD [14,15]. The bodily pain dimension of the SF-36 physical health component (SF-36BP) was the second comparator used for responsiveness analysis.…”

BackgroundThe Whiplash Disability Questionnaire (WDQ) poses a validated tool for the assessment of patients who experience whiplash-associated disorders. A German translation and cross-cultural adaptation was recently produced and presented high validity and internal consistency. As a follow-up, the presented study tests the translated Whiplash Disability Questionnaire’s (WDQ-G) retest reliability and responsiveness to change.MethodsThe WDQ-G was assessed on three different measurement events: first upon entry (ME1), second four days after entry (ME2), and third at discharge (ME3). Test-retest reliability data from ME1 and ME2 was analysed in a group of stable patients to obtain the intraclass correlation coefficient (ICC) and the standard error of measurement (SEM). To test the instrument’s responsiveness, WDQ-G change data were compared to concurrent instruments. The probability of each instrument, to correctly distinguish patients of the stable phase (ME1 to ME2) from patients who deemed to have improved between from ME1 to ME3, was analysed.ResultsIn total, 53 patients (35 females, age = 45 ± 12.2) were recruited. WDQ-G scores changed from ME1 to ME2 by 5.41 ± 11.6 points in a stable group. This corresponds to a test-retest reliability of ICC = 0.91 (95% CI = 0.80–0.95) with a SEM of 6.14 points. Minimal Detectable Change, at 95% confidence, was calculated to be 17 points change in scores. Area under Receiver Operator Characteristics of the WDQ-G’s responsiveness revealed a probability of 84.6% (95% CI = 76.2%–93%) to correctly distinguish between improved and stable patients. Optimal sensitivity (73.2%) and specificity (76.2%) was established at 11-point change.ConclusionsHigh retest reliability and good responsiveness of the WDQ-G support clinical implementation of the translated version. The data suggest, that change in total score greater than eleven points can be interpreted as clinical relevant from a patient’s perspective. Minimal Important Change is suggested at 15 points where there is still high specificity and a 90% confidence MDC.

“…A change of one point is considered to be clinically relevant [13]. The NASS has been officially translated into German showing a very good reliability for both subscales (0.90 and 0.89) [13,14] and have been used in WAD patients [15,16]. The total score of subscale pain and disability (11 questions) was used to test the concurrent validity with the WDQ-G.…”

BackgroundThe Australian Whiplash Disability Questionnaire (WDQ) was cross-culturally translated, adapted, and tested for validity to be used in German-speaking patients. The self-administered questionnaire evaluates actual pain intensity, problems in personal care, role performance, sleep disturbances, tiredness, social and leisure activities, emotional and concentration impairments with 13 questions rated on an 11-point rating scale from zero to ten.MethodsIn a first part, the Australian-based WDQ was forward and backward translated. In a consensus conference with all translators and health care professionals, who were experts in the treatment of patients with a whiplash associated disorder (WAD), formulations were refined. Original authors were contacted for clarification and approval of the forward-backward translated version. The German version (WDQ-G) was evaluated for comprehensiveness and clarity in a pre-study patient survey by a random sample of German-speaking patients after WAD and four healthy twelve to thirteen year old teenagers.In a second part, the WDQ-G was evaluated in a patient validation study including patients affected by a WAD. Inpatients had to complete the WDQ-G, the North American Spine Society questionnaire (NASS cervical pain), and the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) at entry in the rehabilitation centre.ResultsIn the pre-study patient survey (response rate 31%) patients rated clarity for title 9.6 ± 0.9, instruction 9.3 ± 1.4 and questions 9.6 ± 0.7, and comprehensiveness for title 9.6 ± 0.7, instruction 9.3 ± 1.4 and questions 9.8 ± 0.4. Time needed to fill in was 13.7 ± 9.0 minutes.In total, 70 patients (47 females, age = 43.4 ± 12.5 years, time since injury: 1.5 ± 2.6 years) were included in the validation study. WDQ-G total score was 74.0 ± 21.3 points (range between 15 and 117 points). Time needed to fill in was 6.7 ± 3.4 minutes with data from 22 patients. Internal consistency was confirmed with Cronbachs’s α = 0.89. Concurrent validity showed a highly significant correlation with subscale pain and disability (NASS) at r = 0.74 and subscale pain (SF-36) at r = 0.71.ConclusionsThe officially translated and adapted WDQ-G can be used in German-speaking patients affected by a WAD to evaluate patients’ impairments in different domains. The WDQ-G is a self-administered outcome measure showing a high internal consistency and good concurrent validity.

Lumbar discogenic pain in the sense of an internal disc disruption (IDD) represents a nociceptive pain syndrome with the source of pain in the innervated outer third of the annulus. Such discs anatomically appear with almost normal contours. Neither clinical nor technical assessments have any diagnostic value, with the exception of MRI which has been shown, if present in symptomatic patients, to have a positive predictive value of up to 89 % to indicate a strong correlation to a painful grade 3 or 4 fissure. However, only the stimulation of a disc (controlled provocation discography) with a subsequent CT scan is of exclusive diagnostic value. As an underlying pathomechanism, a compression fracture of the superior subchondral endplate like a fatigue fracture is discussed. In this way, a deterioration of the homogeneous intradiscal stress distribution could occur with consecutive damage to the internal disc environment and the expression of a radial fissure. The clinical picture of discogenic pain is non-specific. It does not correlate with degenerative changes. It does not differ from any other back pain. Thus, it has to be differentiated from zygapophysial joint pain as well as from sacroiliac joint pain and muscular-ligamentous pain sources. In a single study of American workers, the prevalence of IDD was 39 %, rendering it one of the most important causes for patients with a specified source of back pain.
