Background: Recent studies have found that acupuncture treatments lower blood pressure. Acupuncture is a traditional Chinese medical technique of inserting needles at particular points on the body to balance the opposing forces of yin and yang and the smooth flow of qi. Laser acupoint technique is considers as saving time because it is performed in less time than needles acupuncture.
Purpose: The aim of this study was to study the effect of laser acupuncture on lowering the primary type of hypertension in old female adults.
Materials and Methods: Thirty female mild hypertensive patients with ranged age 50-59 years were enrolled in the study. Systolic and diastolic blood pressure evaluated by Mercury sphygmomanometer. Baseline blood pressure measured for each subject prior to the initiation of the treatment and after enrolled in of treatment program. The anthropometric data including age, duration of hypertension, height, weight and body mass index (BMI) was collected for both experimental and six weeks control groups.
Results: after treating hypertension patients by the laser acupuncture for 6 weeks (twice per week session), both the systolic blood pressure (SBP) and diastolic blood pressure (DBP) decreased significantly (P < .01). The mean SPB in experimental group (Group I) was 155.9 ± 4.33 mm Hg before the treatment and was reduced to 134.1 ± 2.33 mm Hg (P < .001) after treatment. While the mean SPB in control group (Group II) was 156.2 ± 3.88 mm Hg before the treatment and was reduced to 152.9 ± 2.85 mm Hg (P < .002) after treatment. The mean DBP in Group I was 91.5 ± 2.55 mm Hg before treatment and was reduced to 82.6 ± 2.12 mm Hg (P < .001), While the mean DBP in Group II was 91.1 ± 2.85 mm Hg before the treatment and was reduced to 89.2 ± 2.1 mm Hg (P < .002) after treatment.
Conclusion: we concluded that low-level laser acupuncture treatment resulted in lower blood pressure by stimulating these points LI 4 LI 11, Sp 6 and P 6.
