Low Back Pain Rating scale is an index scale which includes measurements of pain intensity, disability, and physical impairment. The scale was designed to monitor the outcome of clinical trials of low back pain treatment. It has been validated in 58 patients following first-time discectomy. The scale rating can be rapidly carried out and requires no special aids. With slight modification it can be used in office and telephone interviews, as well as postal questionnaires. These modifications only slightly reduce the quantity of information gathered. In the study, a high rater agreement (97.7%) was found without level difference between two observers using the scale. The validation process included: construct validity, criterion-related validity and item bias, relative to Global Assessments pronounced by the patient and an experienced clinician. Low Back Pain Rating scale hs been shown to be valid and reliable in the assessment of low back pain.

Men and women demonstrate impressive levels of muscular strength in the flexors and extensors of the cervical spine and can maintain these values until the seventh decade of life. Successful rehabilitation of the cervical musculature will require considerable resistance for sufficient stimulation of the cervical musculature.

There was no clinical difference between the three treatments. All three treatment interventions demonstrated meaningful improvement in all primary effect parameters. Improvements were maintained at 4- and 12-month follow-up. However, whether this was a result of the treatments or simply a result of time is unknown. Future studies will be necessary to delineate ideal treatment strategies.

Grading pain intensity scales into simple categories provides useful information for both clinicians and epidemiologists and methods to classify pain severity for numerical rating scales have been recommended. However, the establishment of cut-points is still in its infancy and little is known as to whether cut-points are affected by age or gender. The objectives of this paper were to establish optimal cut-points in pain severity in individuals with neck pain (NP) and to investigate if the cut-points were influenced by gender, age, and NP duration. Data from the population-based ;Funen Neck and Chest Pain Study' was used. Univariate and multivariate analyses of variance were performed to calculate optimal single and double cut-points for three different pain intensity scores within the past 2 weeks relative to two neck disability scales (;global assessment of NP' and the ;Copenhagen Neck Functional Disability Scale'). The two disability scales showed small differences in optimal cut-points. Furthermore, cut-points changed for each of the three pain intensity scales. Only small gender differences in cut-points were seen and no specific trend was noted in either single or double cut-points in different age groups. The cut-points were almost identical for acute, subacute, and chronic NP. This paper has implications for understanding the impact of using different pain intensity scales and provides reference cut-points in NP for use in future clinical and epidemiological research.
