Randomized Controlled Trial Comparative Study
Comparison of general exercise, motor control exercise and spinal manipulative therapy for chronic low back pain: A randomized trial.
Practice guidelines recommend various types of exercise and manipulative therapy for chronic back pain but there have been few head-to-head comparisons of these interventions. We conducted a randomized controlled trial to compare effects of general exercise, motor control exercise and manipulative therapy on function and perceived effect of intervention in patients with chronic back pain. Two hundred and forty adults with non-specific low back pain 3months were allocated to groups that received 8weeks of general exercise, motor control exercise or spinal manipulative therapy. ⋯ The motor control exercise group had slightly better outcomes than the general exercise group at 8weeks (between-group difference: PSFS 2.9, 95% CI: 0.9-4.8; GPE 1.7, 95% CI: 0.9-2.4), as did the spinal manipulative therapy group (PSFS 2.3, 95% CI: 0.4-4.2; GPE 1.2, 95% CI: 0.4-2.0). The groups had similar outcomes at 6 and 12months. Motor control exercise and spinal manipulative therapy produce slightly better short-term function and perceptions of effect than general exercise, but not better medium or long-term effects, in patients with chronic non-specific back pain.

The majority of research on pain catastrophizing has focused on its negative consequences for adjustment to chronic pain, with few investigations of factors that influence catastrophizing or its detrimental effects. Using a daily process methodology, the current study examined, first, the extent to which a supportive social environment plays a role in reduced catastrophizing, and second, the extent to which support might protect against the detrimental effects of catastrophizing on well-being. Sixty-nine married individuals with rheumatoid arthritis took part in an initial background interview, followed by twice daily telephone interviews (regarding pain intensity, negative affect, catastrophizing and satisfaction with spouse responses) for 1 week. ⋯ The relationship between pain and catastrophizing was attenuated in the context of increases in satisfaction with spouse responses. Negative affect was associated with increases in catastrophizing, but only when individuals reported decreases in satisfaction with spouse responses. Overall, findings were consistent with a model in which satisfaction with spouse responses serves as a coping resource, and suggests the importance of involving close others in treatments to reduce pain and catastrophizing.

Assessing the experience and impact of pain in adolescents with chronic pain is necessary to guide both individual treatment and to inform treatment development. Ideally, to obtain a comprehensive understanding of the impact of pain, assessment should be multidimensional, should be sensitive to contextual variables, and should allow for multiple informants (in particular, parents). The purpose of this study was to develop a standardized parent-report measure of chronic pain in adolescents, the Bath Adolescent Pain Questionnaire - Parent report (BAPQ-P). ⋯ Validity was examined in relation to existing validated child report measures of anxiety, depression, catastrophizing, disability, family, and social functioning and parent report measures of disability and family functioning. Psychometric evaluation suggests that the BAPQ-P is a reliable and valid parental report tool for assessing the multidimensional impact of adolescent chronic pain. It can be used in conjunction with the previously established adolescent self-report measure, the BAPQ, alone where adolescent self report is not possible, in studies where parent report is the focus, or in studies where concordance between parent and adolescent reports is of interest.

Little is known about how patient functioning changes after completion of multidisciplinary pain programs, and what factors are associated with such changes when they occur; for example, whether improvement or deterioration in functioning corresponds to changes in patient beliefs and coping during this period. The objective of this study was to examine the extent to which changes in patient pain and functioning were associated with changes in beliefs and coping after multidisciplinary pain treatment. Patients with chronic pain (N=141) completed outcome (pain, functioning) and process (beliefs, catastrophizing, coping) measures at the end of multidisciplinary pain treatment and 12 months posttreatment. ⋯ Decreased perceived control over pain was also consistently associated with worsening of these outcomes. The results highlight the potential importance of specific pain-related beliefs and coping responses in long-term patient pain and adjustment. Research is needed to determine whether booster interventions after the end of intensive multidisciplinary treatment that target these beliefs and coping responses improve long-term outcomes.

Many children and adolescents experience recurrent pain, but only a few become disabled by it. Research has established that higher pain intensity and worse depression seem to predict poorer functioning in this population. Parent and family variables have been minimally researched. ⋯ Pain intensity and depression predicted functional disability. However, social/adaptive functioning was associated with different variables, including parent factors, and school attendance showed no association with pain intensity or anxiety. The results emphasise the need to measure multiple domains of functioning, and show that the connections between pain, physical disability and adaptive functioning are looser than might be predicted.
