Brief Summary

Puerperal mastitis is one of the most commonly reported problems during breastfeeding. Women frequently report breast pain, tenderness, redness, engorgement, fever, malaise, chills, lethargy, sweating, headache, nipple damage and a hot spot on the affected breast. These highly distressing symptoms may severely impact on a woman's daily activities and quality of life and might lead to the premature cessation of exclusive breastfeeding, which may have significant impact on infant health and survival. The role of physical therapy in reducing pregnancy/postpartum-related disorders including breast problems is gaining momentum and importance in obstetrics. However, to date, only low-level evidence has shown positive effects of breast massage, a physical technique, on pain, milk supply and symptom relief in women with breastfeeding problems. This is encouraging, however further research is needed to explore whether physical therapy is effective to reduce symptoms of puerperal mastitis. The investigators will conduct a prospective, assessor blinded single-center randomized controlled trial to assess the effectiveness of an individualized physical therapy program with therapeutic ultrasound, education and massage for patients with puerperal mastitis, compared to patients receiving usual obstetric care and sham ultrasound treatment.

Outcome Measures

Primary Outcomes (1)

  • Breast and Nipple Pain

    Breast and nipple pain in the past 24 hours will be assessed using the numerical rating scale (NRS). Participants will be asked to rate her breast pain and nipple pain from 0 to 10 (11 point scale), with 0 indicating no pain and 10 indicating the worst possible pain.

    3 months

Secondary Outcomes (7)

  • Severity of Breast Engorgement

    3 months

  • Breast Hardness

    3 months

  • Body and Breast Temperature

    3 months

  • Volume of Mother's Milk

    3 months

  • Acceptability of the Intervention Program

  • +2 more secondary outcomes

Study Arms (3)

Intervention group

EXPERIMENTAL

* Educating the patient about mastitis and self-management strategies * Treating with therapeutic ultrasound * Administering and teaching breast massage

Other: EducationOther: Therapeutic ultrasoundOther: Breast massage

Sham group

SHAM COMPARATOR

* Educating the patient about mastitis and self-management strategies * Receiving sham ultrasound * Administering and teaching breast massage

Other: EducationOther: Sham ultrasoundOther: Breast massage

Usual care group

OTHER

Receiving usual obstetric care, which may include verbal advice/printed patient information regarding mastitis and breastfeeding from the medical or nursing staff

Other: Usual obstetric care

Interventions

The education session including education about mastitis, feeding techniques, lifestyle changes, thermal/cryo therapy and demonstration of breast self-massage will take approximately 20 minutes.

Intervention groupSham group

Participants will be treated with 5 minutes of therapeutic ultrasound (pulsed mode) at a frequency of 1 Mega Hertz, a duty cycle of 20%, a pulse intensity of 1.8 Watt/centimetre squared. The ultrasound probe will be moved at a speed of about 4 centimetre/second. The intensity and duration will be adjusted if the patient complains of discomfort. The ultrasound transducer head will massage over the tender point on the breast.

Intervention group

Participants will receive 5 minutes of 'sham' ultrasound at 0 Watt/centimetre squared intensity from a physical therapist.

Sham group

Breast massage includes general and focused massage. Participants will lie in supine position. The breast massage will be applied according to the Vodder method to the affected breast.

Intervention groupSham group

Usual obstetric care may include verbal advice/printed patient information regarding mastitis and breastfeeding from the medical or nursing staff.
