Laser acupuncture improving functional chronic constipation in children: a randomized controlled trial.

Functional chronic constipation (FCC) is a disorder caused by low fiber consumption, lack of fluid intake, lack of mobility, or side effects of medications. The objective of this study was to compare the effects of laser acupuncture and the commonly used osmotic laxative, lactulose (as the control), both combined with behavioral therapy and dietary modification, on children with FCC in a randomized controlled trial (RCT). Forty children were randomly chosen, aged 5-15 years with FCC, and randomized into two equal groups (gender ratio (50% male; 50% female), mean ± SD weight (24.2 ± 6.27 kg and 25.7 ± 7.47 kg for groups A and B, respectively)). Study group (group A): used laser acupuncture (650 nm), 30 mW, 0.15 cm2 spot size, 90 s per acupuncture point (ST25, ST36, ST37, BL25, and LI11). Control group (group B): lactulose syrup (1 to 3 mL/kg/day) orally, in divided doses 3 times weekly for 4 weeks, and behavioral training for both groups. Evaluations were conducted before and after the study to assess the efficacy of the therapy. Median value frequency significantly increased in groups A and B post-treatment (4 (6.75-3) and 3 (3.75-2), respectively) compared to pre-treatment (2 (2-1) and 2 (2-0.25), respectively) (p = 0.0001), in favor of group A (p = 0.01). Significant improvement of stool consistency according to Bristol stool scale (BSS) in groups A and B (p = 0.0001), (p = 0.002) respectively in favor of group A (p = 0.03). T-test, Fisher, and Wilcoxon signed rank tests were conducted to compare groups. Non-invasive, painless laser acupuncture therapy can be considered as an alternative therapy for patients with FCC.
