Evidence supports abdominal massage (AM) or electrical stimulation (ES) as effective in treating functional constipation (FC). Manual lymph drainage (MLD) may also be beneficial, however, it was not previously investigated or compared to ES and AM.
Sixteen college-aged males and 36 females were recruited. Participants were randomly assigned to MLD, AM or ES. Heart rate variability (HRV) measures for total power (TP), high frequency (HF), low frequency and LF/HF ratio assessed ANS outcomes. state-trait anxiety inventory (STAI) and stress response inventory (SRI) assessed psychological factors and bowel movement frequency (BMF) and duration (BMD) were recorded daily.
MLD significantly improved all ANS measures (p≤0.01); AM significantly improved LF, HF and LF/HF ratios (p = 0.04); and ES significantly improved LF (p = 0.1). STAI measures improved, but not significantly in all groups. SRI improved significantly from MLD (p < 0.01), AM (p = 0.04) and ES (p < 0.01), but changes were not significant between groups. BMD improved significantly in all groups (p≤ 0.02). BMF improved significantly only following MLD and AM (p < 0.1), but differences between groups were not significant (p = 0.39).
MLD significantly reduced FC symptoms and MLD had greater improvements than AM or ES.
有证据表明腹部按摩（AM）或电刺激（ES）在治疗功能性便秘（FC）方面有效。手动淋巴引流（MLD）也可能有益，但之前并未对其进行研究或与 ES 和 AM 进行比较。
招募了 16 名大学生和 36 名女性。参与者被随机分配到 MLD、AM 或 ES 组。心率变异性（HRV）测量总功率（TP）、高频（HF）、低频和 LF/HF 比评估自主神经系统（ANS）结果。状态-特质焦虑量表（STAI）和应激反应量表（SRI）评估心理因素，每日记录排便频率（BMF）和排便时间（BMD）。
MLD 显著改善了所有 ANS 测量值（p≤0.01）；AM 显著改善了 LF、HF 和 LF/HF 比值（p=0.04）；ES 显著改善了 LF（p=0.1）。STAI 测量值有所改善，但在所有组中均不显著。SRI 从 MLD（p<0.01）、AM（p=0.04）和 ES（p<0.01）显著改善，但组间变化不显著。所有组的 BMD 均显著改善（p≤0.02）。BMF 仅在 MLD 和 AM 后显著改善（p<0.1），但组间差异无统计学意义（p=0.39）。
MLD 显著减轻了 FC 症状，且 MLD 的改善程度大于 AM 或 ES。
