Randomized Controlled Trial Comparative Study Clinical Trial
A randomized clinical trial of three active therapies for chronic low back pain.
A randomized clinical trial. ⋯ The general lack of treatment specificity suggests that the main effects of the therapies were educed not through the reversal of physical weaknesses targeted by the corresponding exercise modality, but rather through some "central" effect, perhaps involving an adjustment of perception in relation to pain and disability. The direct costs associated with administering physiotherapy were three times as great, and devices four times as great, as those for aerobics. Administration of aerobics as an efficacious therapy for chronic low back pain has the potential to relieve some of the huge financial burden associated with the condition.

Randomized Controlled Trial Clinical Trial
Information and advice to patients with back pain can have a positive effect. A randomized controlled trial of a novel educational booklet in primary care.
A double-blind, randomized controlled trial of a novel educational booklet compared with a traditional booklet for patients seeking treatment in primary care for acute or recurrent low back pain. ⋯ This trial shows that carefully selected and presented information and advice about back pain can have a positive effect on patients' beliefs and clinical outcomes, and suggests that a study of clinically important effects in individual patients may provide further insights into the management of low back pain.

Pain intensity ratings of 'usual' pain, or pain 'on average', are gaining in popularity since they are arguably a more realistic measure of a patient's pain status than the single snapshot of 'current' pain. An alternative to the 'actual average' of ratings obtained from multiple measures is the single rating of patients' recall of their 'usual' pain over a period of time, usually 1 week. The use of such a scale relies on the assumption that patients can accurately recall their 'usual' pain. ⋯ Using the Intra-class Correlation Coefficient (ICC) to compute accuracy, the single rating asking patients to estimate their pain 'on average' over the week was found to be an accurate measure of 'actual average' pain intensity (ICC=0.82) and more accurate than 'current' pain (ICC=0.66). Although some composite measures of single ratings gave more accurate estimates of 'actual average' pain, this was not considered sufficient advantage to advocate their use. The results of this study propose the single rating of pain 'on average' as a valid and practical measure of a patient's pain intensity over a period of 1 week.

This study investigates whether different subgroups of chronic low back pain patients (CLBPs) differ in psychological aspects assessed with the Symptom Checklist (SCL-90) and the Multidimensional Pain Questionnaire (MPI-DLV). Four subgroups of CLBPs are discerned using the results of lumbar dynamometry: 1. Patients with performances lower than healthy subjects (expected performance; n = 45). 2. ⋯ Significant differences in psychological aspects were found between patients with submaximal and patients with expected performances but not between patients with normal and patients with expected performances. All patients with submaximal performance report a high degree of psychological distress, in contrast to 30% of those with normal performance and 20% of those with expected performance. Because of the differences found in psychological aspects between the CLBP subgroups, it is thought that a physical screening together with a psychological screening provides better insight in the two aspects of the deconditioning syndrome and thus can give better treatment indications than a physical screening alone.

Randomized Controlled Trial Clinical TrialChronic low-back pain: what does cognitive coping skills training add to operant behavioral treatment? Results of a randomized clinical trial.
This study examined the supplemental value of a cognitive coping skills training when added to an operant-behavioral treatment for chronic low-back pain patients. The complete treatment package (OPCO) was compared with an operant program + group discussion (OPDI) and a waiting-list control (WLC). After the WL period, the WLC patients received a less protocolized operant program usually provided in Dutch rehabilitation centers (OPUS). ⋯ At posttreatment, OPCO led to better pain coping and pain control than OPDI. Calculation of improvement rates revealed that OPCO and OPDI had significantly more improved patients than OPUS on all the dependent variables. The discussion includes findings regarding treatment credibility, compliance, and contamination bias.
