- Many of the existing low back pain (LBP) questionnaires of function and symptoms have a content of different domains of disability presented as a single sum score, making it difficult to derive changes within a specific domain. The present study describes the development of a clinically derived back-specific questionnaire incorporating both a functional limitation and a symptom scale, with a further subdivision of the symptom scale in separate indices for severity and temporal aspects. The aims of the study were to assess the overall reliability and validity of the new questionnaire, named the Profile Fitness Mapping questionnaire (PFM). A total of 193 chronic LBP patients answered the PFM together with five validated criterion questionnaires. For the internal consistency of the questionnaires, the three indices of the PFM had the highest Cronbach's alpha (0.90-0.95) and all items had item-total correlations above 0.2. The correlation coefficients between the PFM and the back-specific criterion questionnaires ranged between 0.61 and 0.83, indicating good concurrent criterion validity. The best discriminative ability between patients with different pain severities was demonstrated by the functional limitation scale of the PFM. Well centered score distribution with no patient's score at the floor or the ceiling level indicates that the PFM has the potential to detect the improvement or worsening of symptoms and functional limitations in chronic LBP patients. Classification according to the International Classification of Functioning, Disability and health (ICF) of WHO revealed a high degree of homogeneous item content of the symptom scale to the domain of impairments, and of the functional limitation scale to the domain of activity limitations. The present study suggests that the PFM has a high internal consistency and is a valid indicator of symptoms and functional limitations of LBP patients. It offers the combination of a composite total score and the possibility of evaluations within specific domains of disability. Complementary evaluation of test-retest reliability and responsiveness to change is warranted.

The aim of the study was to assess theoverall validity of the PFM.Methods and Results: Chronic LBP-patients (n=193) answered thePFM and four validated back-specific criterion questionnaires.The correlation coefficients between the PFM and the criterionquestionnaires showed good concurrent criterion validity (0.61– 0.83). The best discriminative ability between patientswith different pain severity was demonstrated by the functionallimitation scale of the PFM. Classification according to theICF revealed a high degree of homogeneous item content of thesymptom scale to the domain of impairments, and of the functionallimitation scale to the domain of activity limitations.

- Purpose: To assess overall reliability and validity of a neck-specific questionnaire, the Profile Fitness Mapping neck questionnaire (ProFitMap-neck), on three chronic neck pain groups. Method: Participating groups were as follows: whiplash associated disorders, inpatient care (IP-WAD, n = 127); nonspecific neck pain, inpatient care (IP-NS, n = 83) and nonspecific neck pain subjects (non-IP-NS, n = 104). All groups answered the ProFitMap-neck and the SF-36, whereas non-IP-NS also answered the Neck Disability Index (NDI) and the Functional Self-Efficacy Scale (SES). Internal consistency, test-retest reliability and components of convergent construct, face and content validity were determined for the ProFitMap-neck. Results: The ProFitMap-neck showed good internal consistency in all three groups, and ICC test-retest reliability (0.80-0.91). Good correlation (0.66-0.78) and highest agreement was reached with NDI. According to the International Classification of Functioning, Disability and Health, the symptom scale of the ProFitMap-neck was mainly classified to the domain of impairments-body functions, and the functional limitation scale to the activity limitation domain. Conclusion: The results indicate that the ProFitMap-neck is valid for measuring symptoms and functional limitations in people with chronic neck pain. The combination of a composite total score of symptoms and function as well as separate scores of each domain makes ProFitMap-neck suitable for research as well as in clinical practice.

Tidskriftsartikel (refereegranskat)abstract
- Objective: The aim of the present study was to compare autonomic activity, pressure-pain thresholds, and subjective assessments of health and behavior between patients with stress-related illnesses and healthy control subjects. Methods: Twenty sick-listed patients with stress-related disorders and 20 age- and gender-matched healthy subjects performed tests of autonomic regulation and algometric tests, and completed questionnaires about physical and mental health and behavioral patterns. Results: Patients exhibited higher autonomic reactivity to cognitive and physical laboratory tasks (p<0.05), and had lower pressure-pain thresholds in the shoulders and lower back than healthy control subjects (p<0.05). Furthermore, the patients rated considerably poorer health and health behavior than the control subjects (p<0.05). Conclusions: The results indicate an engagement of the autonomic nervous system in stress-related illnesses. Furthermore, they show that patients with stress-related illnesses experience strong symptoms of musculoskeletal pain, and it is therefore recommended that assessments of musculoskeletal pain be incorporated in the clinical examinations and the rehabilitation of patients with stress-related illnesses.

- The aim of the present study was to examine the effects of cognitive behavioral group treatment and physical activity for patients with stress-related illnesses. Sixty patients were randomly allocated to one of three groups, so that each group contained twenty patients. Group A received cognitive behavioral group treatment, group B participated in physical activity, and group C constituted a control group thus receiving no treatment during the course of the study. Measurements of autonomic activity, pain sensitivity, and subjective health assessments were performed before and after a 10-week intervention period, consisting of two gatherings per week for the cognitive behavioral treatment group, and two exercise sessions per week for the physical activity group. Each of the two treatment groups assembled at 1.5, 3, and 6 months after the intervention, and follow-up measurements on all participants were performed at 6 and 12 months after the intervention. For comparison, measurements were performed at one occasion on healthy subjects of the same age and gender distribution as the patients. Patients exhibited higher autonomic reactivity to cognitive and physical laboratory tasks (p<0.05), had lower pressure-pain thresholds in the shoulders and lower back (p<0.05), and rated poorer health than healthy subjects (p<0.01). No overall effect of cognitive behavioral group treatment or physical activity was found on autonomic activity (p>0.06) or pressure-pain thresholds (p>0.71), although patients who received cognitive behavioral group treatment reported improved health (p<0.05). The results suggest little difference in effect of cognitive behavioral group treatment and physical activity on patients with stress-related illnesses

- OBJECTIVE: To evaluate the effects of a cognitive behavioural training programme and a physical activity programme for patients with stress-related illnesses. DESIGN: In a randomized controlled study, patients were allocated randomly to 1 of 3 groups, where group 1 participated in a cognitive behavioural training programme, group 2 participated in a physical activity programme, and group 3, the control group, was offered usual care for the course of the study. SUBJECTS: A total of 75 patients participated in the study. They had been on sick leave for at least 50% of the time for between 1 month and 2 years due to stress-related illnesses. METHODS: Measurements of autonomic activity, pressure-pain thresholds and subjective ratings of health and behaviour were made before and after a 10-week intervention period, and at 6 and 12 months after the intervention. RESULTS: Minor differences in autonomic activity and pressure-pain thresholds were found between the groups immediately after the intervention. At the 6- and 12-month follow-up assessments, the differences were no longer present. Patients in the cognitive behavioural training group improved their ratings of general health compared with the physical activity group throughout the study. CONCLUSION: The study showed little difference in the effect of cognitive behavioural training and physical activity, compared with usual care, for patients with stress-related illnesses.
