Hoffman's Exercise for Breastfeeding Support Among Postnatal Mothers With Nipple Defects: A Scoping Review and...

Area of Science:

• Lactation Support
• Postpartum Care
• Nipple Correction Techniques

Background:

• Hoffman's exercise is a common non-surgical method for breastfeeding mothers with inverted or flat nipples.
• Previous reviews indicated potential benefits but lacked detailed analysis of comparator effects and study designs.
• This highlights limitations in current clinical guidance and trial planning.

Purpose of the Study:

• To provide a comparator-aware analysis of Hoffman's exercise effectiveness.
• To differentiate between-group and within-group changes.
• To clarify credible evidence and identify research gaps.

Main Methods:

• Exploratory, hypothesis-generating analysis of 10 heterogeneous studies.
• Acknowledged risk of estimate inflation due to low study quality.
• Stratified analysis by comparator and separated effect types.

Main Results:

• Critically low quality of primary studies limited meta-analysis.
• Exploratory analysis suggested possible benefit versus routine care, but not against the inverted syringe technique.
• Within-group improvements were observed but were noncausal and prone to confounding.

Conclusions:

• Current evidence is insufficient for strong claims about Hoffman's exercise effectiveness.
• The technique should be offered as part of a broader lactation support bundle.
• Further robust research is required to determine clinical effectiveness.
