- 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.

- Background: Disability questionnaires for LBP-patients mostlyemanate from health professionals and have a content of differentdomains of disability presented as a single sum score, makingit difficult to derive changes within a specific domain. Thisstudy introduces a new back-specific questionnaire, the ProfileFitness Mapping questionnaire (PFM), which was based on patient’sself-reported characteristics of the LBP. The PFM incorporatesboth a functional limitation and a symptom scale, with furthersubdivision of the symptom scale in separate indices for severityand temporal aspects. 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. Wellcentered score distribution indicates that the PFM has the potentialto detect improvement or worsening of symptoms and functionallimitations in chronic LBP-patients.Conclusion: The results of the study signify that the PFM isa valid indicator of symptoms and functional limitations ofLBP-patients. It provides the combination of a composite totalscore and the possibility of evaluations within specific domainsof disability.

- OBJECTIVE: To evaluate whether patients suffering from whiplash-associated disorders have impaired shoulder proprioception and whether the acuity of shoulder proprioception is reflected in the patients' symptoms and self-rated function. DESIGN: A comparative group design, including a correlation design for the patient group. SUBJECTS: Patients with chronic whiplash-associated disorders (n=37) and healthy subjects (n=41). The groups were matched for age and gender. METHODS: All subjects underwent a shoulder proprioception test involving active ipsilateral arm position-matching. Group difference was evaluated by multiple analysis of variance and analysis of variance. The patient group completed questionnaires addressing functioning and health and performed pain ratings. Associations between proprioceptive acuity and self-rated functioning and symptoms were studied by correlation and regression analyses. RESULTS: The patient group showed significantly lower acuity of shoulder proprioception. Moderate correlations were found between proprioceptive acuity and questionnaire scores representing physical functioning, so that low proprioceptive acuity was associated with low self-rated physical functioning. Scores representing pain-intensity did not correlate with proprioceptive acuity. CONCLUSION: The results show that, at the group level, patients with whiplash-associated disorders have impaired shoulder proprioception. The clinical relevance of this finding is strongly supported by the association between shoulder proprioceptive acuity and self-rated functioning in the patient group.
