Health-related quality of life in 975 patients with complex regional pain syndrome type 1
There are limited data available on health-related quality of life (QoL) in patients with complex regional pain syndrome (CRPS). In the present study we examined QoL in 975 CRPS patients attending 6 different clinics in the Netherlands. QoL was assessed using the MOS 36-Item Short-Form Health Survey (SF-36) with the Mental Health Summary Score (MHS) and the Physical Health Summary Score (PHS) as dependent variables. The influences of gender, type of affected limb, disease duration, pain scores, CRPS severity and set of diagnostic criteria used were investigated. We found the lowest scores of QoL in the physical domains of the SF-36, with lower-limb CRPS patients reporting poorer results than patients with an affected upper limb. Influence of gender on QoL was not observed, and correlations of QoL with disease duration and the CRPS severity score were weak. Pain correlated moderately with QoL. In addition, patients fulfilling stricter diagnostic criteria (ie, the Budapest criteria) had lower QoL scores than patients fulfilling less strict criteria (ie, the Orlando criteria). We conclude that loss of QoL in CRPS patients is due mainly to reduced physical health. A comparison with data available from the literature shows that CRPS patients generally report poorer QoL than patients with other chronic pain conditions, particularly in the physical domains. Pain correlated moderately with QoL and therefore deserves ongoing attention by physicians. Finally, patients meeting the diagnostic Budapest criteria have lower QoL scores than patients meeting the Orlando criteria, highlighting the impact of different sets of criteria on population characteristics

Distribution of signs and symptoms of Complex Regional Pain Syndrome type I in patients meeting the diagnostic criteria of the international association for the study of pain
The aim of the present study was to describe the occurrence of signs and symptoms in CRPS I patients meeting the IASP (Orlando) criteria, assess the occurrence of signs and symptoms in relation to disease duration and compare these to historical data based on a different diagnostic criteria set. Six hundred and ninety-two ambulatory patients meeting the IASP criteria for CRPS I referred to the outpatient clinics of five participating centers were included in this cross-sectional study. Characteristics were recorded in a standardized fashion and categorized according to the factor structure proposed by Bruehl/Harden. Subgroups were classified according to the duration of complaints and compared to historical data as described by Veldman et al. The Chi-square test corrected for multiple comparisons was used for statistical analysis. The prevalence of sensory signs was higher in patients with longer disease duration, especially for the allodynia's and hyperalgesia (all p 6 months). Prevalences of signs in the motor subgroup were all higher (p < 0.0001) in patients with longer disease duration, except for limited range of motion. Occurrence of signs was significantly lower (<0.001) than those reported by Veldman et al., except for hyperesthesia and dystonia. Occurrence rates may vary at different time points after onset of CRPS, which may be of influence for diagnosing patients with novel derived diagnostic criteria. We argue for a mechanism based description of CRPS I based on one set of uniform generally accepted diagnostic criteria in future studies

Physical activity patterns and clusters in 1001 patients with COPD
We described physical activity measures and hourly patterns in patients with chronic obstructive pulmonary disease (COPD) after stratification for generic and COPD-specific characteristics and, based on multiple physical activity measures, we identified clusters of patients. In total, 1001 patients with COPD (65% men; age, 67 years; forced expiratory volume in the first second [FEV 1 ], 49% predicted) were studied cross-sectionally. Demographics, anthropometrics, lung function and clinical data were assessed. Daily physical activity measures and hourly patterns were analysed based on data from a multisensor armband. Principal component analysis (PCA) and cluster analysis were applied to physical activity measures to identify clusters. Age, body mass index (BMI), dyspnoea grade and ADO index (including age, dyspnoea and airflow obstruction) were associated with physical activity measures and hourly patterns. Five clusters were identified based on three PCA components, which accounted for 60% of variance of the data. Importantly, couch potatoes (i.e. the most inactive cluster) were characterised by higher BMI, lower FEV 1 , worse dyspnoea and higher ADO index compared to other clusters (p < 0.05 for all). Daily physical activity measures and hourly patterns are heterogeneous in COPD. Clusters of patients were identified solely based on physical activity data. These findings may be useful to develop interventions aiming to promote physical activity in COPD
