Comparing the Effect of Foot Massage with Grape Seed Oil and Sweet Almond Oil on Physiological Leg Edema in Primigravidae: A Randomized Clinical Trial

摘要

Background. Leg edema is a prevalent problem in pregnancy causing activity restrictions for pregnant women. This study was performed to compare the effect of foot massage using grape seed oil and sweet almond oil on physiological leg edema. Methods. A randomized clinical trial was conducted on 90 primigravidae referred to public health centres of Zahedan, Iran. The participants’ gestational age was 30–40 weeks. The study was conducted from August 2016 to November 2017. The participants were randomly assigned to three groups (massage with grape seed oil, massage with sweet almond oil, and without intervention). After determining the extent of leg edema, foot massages were done for 20 minutes within 5 days in the two intervention groups. Then, foot circumferences were measured on day 5 after the intervention. Foot circumferences for the control group were measured on days 1 and 5. A nonelastic tape measure was used to measure the circumferences. To analyse the data, SPSS 21 software and statistical tests including one-way ANOVA, Tukey’s test, and paired t-test were used. Results. The results from this study showed a significant difference in the mean score change of foot circumferences between groups (P=0.001). According to the results of Tukey’s test, mean score changes of foot circumferences of both intervention groups were significantly different those of the control group. However, this difference was not significant between the two intervention groups (P=0.865). Conclusion. The findings of this study confirmed the effectiveness of foot massage using grape seed and sweet almond oils to reduce pregnancy physiological edema. Therefore, foot massage with appropriate oils can be used as a useful technique by trained midwives in prenatal care centres or at pregnant women houses. This trial is registered with IRCT2015072723370N1.
