“…These values are consistent with those obtained by Srifi and collaborators [10] (65, SD: 14.5 for the first visit, and 63.2, SD: 16.6 for the second visit), and are slightly higher than those published by Ediz and his colleagues [9] (55.22, SD: 21.96 and 57.16, SD: 22.48, respectively).…”

“…Construct validity was evaluated with Pearson’s r correlation coefficients correlating the FIQR total score with the former FIQ, the HADS, and the BPI for convergent validity, and with the SF-36 for divergent validity. Guided by previous research on FIQR validations [9,10] we expected to find internal consistency values (Cronbach’s α) ≥ 0.80, test-retest reliability values (ICC) ≥ 0.70, and convergent and divergent validity values showing at least moderate to important correlations between the FIQR and the target scales (Pearson’s r values in the range of 0.40 to 0.70). Given these values we estimated that sample sizes in the range of 20 to 60 subjects would be sufficient to estimate correlations between 0.40 and 0.70 assuming a 5% as significance level and 90% power.…”

BackgroundThe Revised version of the Fibromyalgia Impact Questionnaire (FIQR) was published in 2009. The aim of this study was to prepare a Spanish version, and to assess its psychometric properties in a sample of patients with fibromyalgia.MethodsThe FIQR was translated into Spanish and administered, along with the FIQ, the Hospital Anxiety Depression Scale (HADS), the 36-Item Short-Form Health Survey (SF-36), and the Brief Pain Inventory (BPI), to 113 Spanish fibromyalgia patients. The administration of the Spanish FIQR was repeated a week later.ResultsThe Spanish FIQR had high internal consistency (Cronbach’s α was 0.91 and 0.95 at visits 1 and 2 respectively). The test-retest reliability was good for the FIQR total score and its function and symptoms domains (intraclass correlation coefficient (ICC > 0.70), but modest for the overall impact domain (ICC = 0.51). Statistically significant correlations (p < 0.05) were also found between the FIQR and the FIQ scores, as well as between the FIQR scores and the remaining scales’ scores.ConclusionsThe Spanish version of the FIQR has a good internal consistency and our findings support its validity for assessing fibromyalgia patients. It might be a valid instrument to apply in clinical and investigational grounds.

“…HCs completed the Symptom Impact Questionnaire, which is the same as the FIQR but replaces the word "fibromyalgia" with the word "health" [20]. The FIQR has been shown to have construct validity, good test-retest reliability, content relevance and sensitivity to change for improvement and decline of health status [21]. Total FIQR scores range from 0 to 100, with higher scores indicating a greater negative impact of FM.…”

Postural control deficits in people with fibromyalgia: a pilot study

et al. 2011

IntroductionPostural instability and falls are increasingly recognized problems in patients with fibromyalgia (FM). The purpose of this study was to determine whether FM patients, compared to age-matched healthy controls (HCs), have differences in dynamic posturography, including sensory, motor, and limits of stability. We further sought to determine whether postural instability is associated with strength, proprioception and lower-extremity myofascial trigger points (MTPs); FM symptoms and physical function; dyscognition; balance confidence; and medication use. Last, we evaluated self-reported of falls over the past six months.MethodsIn this cross-sectional study, we compared middle-aged FM patients and age-matched HCs who underwent computerized dynamic posturography testing and completed the Fibromyalgia Impact Questionnaire-Revised (FIQR) and balance and fall questionnaires. All subjects underwent a neurological and musculoskeletal examination. Descriptive statistics were used to characterize the sample and explore the relationships between variables. The relationships between subjective, clinical and objective variables were evaluated by correlation and regression analyses.ResultsTwenty-five FM patients and twenty-seven HCs (combined mean age ± standard deviation (SD): 48.6 ± 9.7 years) completed testing. FM patients scored statistically lower on composite sensory organization tests (primary outcome; P < 0.010), as well as with regard to vestibular, visual and somatosensory ratio scores on dynamic posturography. Balance confidence was significantly different between groups, with FM patients reporting less confidence than HCs (mean ± SD: 81.24 ± 19.52 vs. 98.52 ± 2.45; P < 0.001). Interestingly, 76% to 84% of FM patients had gastrocnemius and/or anterior tibialis MTPs. Postural stability was best predicted by dyscognition, FIQR score and body mass index. Regarding falls, 3 (11%) of 27 HCs had fallen only once during the past 6 months, whereas 18 (72%) of 25 FM patients had fallen at least once. Fifteen FM patients (60%) reported falling at least three times in the past six months.ConclusionsIn this study, we report that middle-aged FM patients have consistent objective sensory deficits on dynamic posturography, despite having a normal clinical neurological examination. Further study is needed to determine prospective fall rates and the significance of lower-extremity MTPs. The development of interventions to improve balance and reduce falls in FM patients may need to combine balance training with exercise and cognitive training.

Objective: The role of vitamin D in the etiopathogenesis of fibromyalgia and non-specific musculoskeletal pain is controversial. In our study, we aimed to investigate the effect of vitamin D therapy on quality of life in patients with fibromyalgia. Materials and Methods:Seventy patients diagnosed with fibromyalgia and 65 age-and sex-matched controls were included in the study. Patients were grouped as deficient (<20 ng/mL), inadequate (20-30 ng/mL), and sufficient (>30 ng/mL) according to the levels of vitamin D. Vitamin D replacement was performed for patients with deficiencies and inadequacies. Before and after vitamin D therapy, patients filled in the assessment tools, fibromyalgia impact questionnaire (FIQ), Arizona sexual experience scale (ASEX), Beck depression inventory (BDI), visual analog scale (VAS), and short form-36 (SF-36).Results: Vitamin D deficiencies and inadequacies were observed in 60% of the patients (n=42). Among patients with low and normal levels of vitamin D, no statistically significant difference was observed in their values. In scales examined after vitamin D replacement therapy, statistically significant differences were observed in the FIQ, BDI, VAS, and SF-36 compared with pre-treatment.
