Studies have demonstrated that exercise can mitigate the intensity of menstrual pain in primary dysmenorrhea, but the most effective type of exercise remains unclear. The objective of this systematic review and network meta-analysis was to evaluate the effectiveness of different exercise regimens in reducing pain associated with primary dysmenorrhoea.
Randomized controlled trials investigating the relationship between menstrual pain and exercise were selected from major electronic databases until February 2, 2024. The primary outcome was the effect of exercise on pain intensity measured by the mean difference on a 10-cm visual analogue scale at 4 and 8 weeks after intervention. The secondary outcome was the difference in risk of dropout at 8 weeks. The study protocol was registered as INPLASY202330050.
This systematic review and network meta-analysis included 29 randomized controlled trials, which involved 1808 participants with primary dysmenorrhea. Exercise interventions included relaxation exercise, strength training, aerobic activity, yoga, mixed exercise, and the Kegel maneuver. Relaxation exercise was the most effective in reducing menstrual pain in 4 weeks (- 3.56; 95% confidence interval: - 5.03 to - 2.08). All exercise interventions were effective in reducing menstrual pain at 8 weeks, with reductions ranging from - 3.87 (95% CI - 5.51 to - 2.22) for relaxation exercise to - 2.75 (95% CI - 4.00 to - 1.51) for yoga, compared to the control group. Relaxation exercises were found to have a significantly lower dropout risk (- 0.11; 95% CI - 0.20 to 0.02), while none of the exercise types was associated with a higher dropout risk than the control group.
All exercise interventions were effective in reducing menstrual pain in primary dysmenorrhea after 8 weeks of intervention. However, relaxation exercise was found to be the most effective intervention at 4 and 8 weeks and had the lowest risk of dropout.
研究表明，运动可以减轻原发性痛经的疼痛强度，但最有效的运动类型仍不明确。本系统评价和网状Meta分析的目的是评估不同运动方案在减轻原发性痛经相关疼痛方面的有效性。
从主要电子数据库中选取截至2024年2月2日调查月经疼痛与运动之间关系的随机对照试验。主要结局是运动对干预后4周和8周时用10厘米视觉模拟量表上的平均差值测量的疼痛强度的影响。次要结局是8周时失访风险的差异。该研究方案已注册为INPLASY202330050。
本系统评价和网状Meta分析纳入了29项随机对照试验，涉及1808名原发性痛经患者。运动干预包括放松运动、力量训练、有氧运动、瑜伽、混合运动和凯格尔运动。放松运动在4周时减轻月经疼痛方面最有效（-3.56；95%置信区间：-5.03至-2.08）。与对照组相比，所有运动干预在8周时均能有效减轻月经疼痛，减轻幅度从放松运动的-3.87（95%CI -5.51至-2.22）到瑜伽的-2.75（95%CI -4.00至-1.51）不等。发现放松运动的失访风险显著更低（-0.11；95%CI -0.20至0.02），而没有一种运动类型的失访风险高于对照组。
所有运动干预在干预8周后均能有效减轻原发性痛经的月经疼痛。然而，发现放松运动在4周和8周时是最有效的干预措施，且失访风险最低。
