Family-based Interventions Benefit Individuals With Musculoskeletal Pain in the Short-term but not in the Long-Term: A Systematic Review and Meta-Analysis.

INTRODUCTION: The benefits of family-based interventions for patients with musculoskeletal pain have been previously shown in individual randomized controlled trials (RCTs), but no systematic review has summarized their effects. MATERIALS AND METHODS: A systematic review was conducted to assess the effectiveness of family-based interventions on clinical and biopsychosocial outcomes in people with musculoskeletal pain (PROSPERO CRD42018118442). Meta-analyses were performed for the outcomes of pain intensity, disability, mood, self-efficacy, and marital adjustment. RESULTS: Of 1223 records identified, 18 reports representing 15 RCTs were included in the qualitative review and 10 in the meta-analyses. Family-based interventions were more effective to reduce pain (mean difference [MD], -3.55/100; 95% confidence intreval [CI], -4.03 to -3.06) and disability (MD, -1.51/100; 95% CI, -1.98 to -1.05) than individual-focused interventions at short-term, but not at mid term or long term. There were no effects on other outcomes. Family-based interventions were more effective to reduce pain (MD, -6.05/100; 95% CI, -6.78 to -5.33) compared with usual care only at short-term. No effects were found on disability and other outcomes. DISCUSSION: There is moderate-quality evidence that family-based interventions result in small, significantly better pain and disability outcomes in the short-term compared with individual-focused interventions in patients with musculoskeletal pain. Based on low-quality evidence, family-based interventions result in small improvements on pain in the short-term compared with usual care. Future studies should review the content and optimize the mechanisms underpinning family-based interventions in musculoskeletal pain so that the approach could be further tested in adequately powered RCTs.

Effects of 9 Months of Martial Arts Training on Cardiac Autonomic Modulation in Healthy Children and Adolescents.

PURPOSE: The aim of the study was to evaluate the cardiac autonomic modulation after 9 months of martial arts practice in healthy children and adolescents. METHOD: The study included 59 children and adolescents who were divided into 3 groups: judo, Muay Thai, and control. Heart rate variability was measured by a heart rate monitor, model Polar RS800CX. The intervention occurred twice a week on nonconsecutive days, lasting 60 minutes each session. A 1-way analysis of variance was used to compare participants at baseline. The comparisons between groups at baseline and after the intervention were carried out by a 2-way analysis of variance for repeated measures. RESULTS: After 9 months of intervention, significant increases were observed for root mean square successive differences, with higher values post compared with baseline (19.5%; P = .04). For SD1, an interaction effect was observed, with increased posttraining values compared with baseline (24.1%; P = .04) for the judo group. Qualitative analysis of the Poincaré plot showed greater dispersion of RR intervals, mainly beat to beat, after the judo intervention compared with the baseline. The Muay Thai and control groups presented no improvement. CONCLUSION: After 9 months of intervention, there were increases in cardiac autonomic modulation of children and adolescents participating in judo training. The practice of martial arts, such as judo, can be encouraged from an early age to improve cardiovascular system functioning, possibly providing protection against cardiovascular problems.
