- Purpose: To investigate the presence of subgroups in chronic whiplash-associated disorders (WAD) based on pain thresholds for pressure (PPT), cold (CPT), and heat (HPT) and to compare these subgroups with respect to symptomatology, disability, and health aspects. Methods: Two groups of female subjects – patients with chronic WAD (n = 28) and healthy controls (CON; n = 29) – were investigated. Quantitative sensory testing (QST) for thermal thresholds and algometry for PPT at four sites in the body (over the trapezius and tibialis anterior bilaterally) were determined. Habitual pain intensities, psychological strain, disability, and health aspects were registered using a questionnaire.Results: A cluster analysis based on PPT, CPT, and HPT identified two subgroups of chronic WAD: one sensitive subgroup (s-WAD; n = 21), and one less sensitive subgroup (ls-WAD; n = 6). S-WAD displayed widespread hyperalgesia, whereas ls-WAD had localized hyperalgesia in the neck area, with tendencies to supernormal values in remote areas of the body. Generally, s-WAD had a significantly worse situation than the CON with respect to symptomatology, disability, and health aspects. The ls-WAD group was intermediary between s-WAD and CON in these aspects.Conclusion: Different explanations, eg, severity of the pain condition per se, etiological factors, and pre-trauma differences in pain sensitivity, may exist for the differences in pain thresholds between the two subgroups. Future research should investigate the role of pain thresholds in the chronic stage to determine the efficacy of treatment interventions.

- Purpose: The purpose of this study was: 1) to determine variables that might characterize good or bad sleep; and 2) to describe the relationship between sleep, impairment of body functions, personal function factors, and quality of life based on quality of sleep in women with fibromyalgia (FM). Methods: This cross-sectional descriptive study included 224 consecutive patients diagnosed at a specialist center. These patients were mailed a questionnaire concerning sleep, body functions, personal factors, and health-related quality of life. In total, 145 completed questionnaires were collected. Results: Using sleep variables (sleep quality, waking up unrefreshed, and tiredness when getting up), we identified two subgroups - the good sleep subgroup and the bad sleep subgroup - of women with FM. These subgroups exhibited significantly different characteristics concerning pain intensity, psychological variables (depressed mood, anxiety, catastrophizing, and self-efficacy), impairments of body functions, and generic and health-related quality of life. The good sleep subgroup reported a significantly better situation, including higher employment/study rate. The bad sleep subgroup reported a greater use of sleep medication. Five variables determined inclusion into either a good sleep or a bad sleep subgroup: pain in the evening, self-efficacy, anxiety, and according to the Short Form health survey role emotional and physical functioning. Conclusion: This study found that it was possible to identify two subgroups of women with FM based on quality of sleep variables. The two subgroups differed significantly with respect to pain, psychological factors, impairments of body functions, and perceived quality of life, where the subgroup with bad sleep had a worse situation.

Quality of life during early radiotherapy in patients with head and neck cancer and pain

Tidskriftsartikel (refereegranskat)abstract
- Background: Patients with head and neck cancer (HNC) have a potentially severe diagnosis and often suffer from tumor-related pain as well as from adverse side effects of treatment such as radiotherapy (RT). Knowledge about quality of life (QoL) during early RT in this group is limited and should be assessed in relation to diagnosis and treatment. Purpose: The purpose of this cross-sectional study was to identify potential factors that may influence QoL in patients with HNC during the early stages of RT (no later than two weeks of ongoing RT). We hypothesized that pain intensity, pain interference, catastrophizing, and mood disturbances are associated with QoL during early RT. Patients and methods: In this study, 54 patients (53% of eligible patients) diagnosed with HNC were consecutively recruited from the regular flow to the Pain and Rehabilitation Center at Linkoping University. The patients completed self-reported questionnaires on sociodemo-graphics, pain intensity, pain interference, anxiety, depression, pain catastrophizing, and QoL. Results: The patients in this study scored high for QoL, low for pain intensity, and low for pain interference. The patients reported minor depressive symptoms and anxiety symptoms. Regression analyses showed that pain intensity and depressive symptoms negatively influenced QoL. Conclusion: No later than two weeks of RT, pain intensity and depression negatively influenced QoL in patients with HNC. Early screening for pain and depression in a targeted preventive strategy might maintain QoL during the course of the RT for patients with HNC. This assumption needs to be further investigated.
