Comparison course of pregnancy related carpal tunnel syndrome in breastfeeding and non-breastfeeding women during the first 6 months after delivery

Abstract

Entrapment of median nerve in carpal tunnel is called carpal tunnel syndrome (CTS). The main purpose of this research is to compare the natural course of the syndrome during the first 6 months after delivery in the women feeding their children using formula and breastfeeding mothers. The present research was done in 50 pregnant women with symptoms and signs of CTS visited by obstetricians and then referred to physiatrist for electrodiagnostic studies. After delivery and confirming the CTS, women classified in two groups: breastfeeding (33) and non-breastfeeding (17) women. The 5 breastfeeding women missed from study. Follow-up of clinical and electrodiagnostic of women were done in first 6 months after delivery. Complete recovery in breastfeeding, non-breastfeeding and all women were10.7%, 52.9% and 26.7%, respectively. Partial recovery in breastfeeding and non-breastfeeding women was 71.4% and 47%, respectively. Complete recovery in mild stage in breastfeeding, non-breastfeeding and all women were 22.2%, 57.1% and 33.3%, respectively. Complete recovery in moderate and severe stages in all women were 23.3%. Rate of complete recovery to partial recovery in non-breastfeeding women was 1.7 times than breastfeeding women. This study was showed the relief of symptoms and reduction of severity of CTS in the women who feed their children on formula is higher than those who breastfeed their children. Pregnancy related CTS would not usually resolve after delivery and must be follow-up by clinical symptoms and electrodiagnostic studies. Hormonal changes during lactation and repetitive motions and/or excessively flexed wrist positions during breastfeeding may be causing aggravated pregnancy related CTS after delivery.
