The purpose of this study is to investigate the effect of Bioptron light therapy on wound healing after caesarean section.

Wound healing process is important after cesarean section without complication and with short period of time; caesarean section (CS) wound complications represent a substantial burden to the health system and the prevention of such complications should be a healthcare priority in developing countries.

Delayed wound healing is when a wound takes longer than normal to heal, it has many hazards such as disruption and fluid collection (hematomas and seromas), adhesions, infection (abscess) and rupture of membranes.

Management and acceleration of wound healing after cesarean section are important for maternal and newborn care and breastfeeding. Many drugs used for this purpose, especially nonsteroidal anti-inflammatory drugs (NSAIDs) and opiates, have side effects including nausea, respiratory distress, gastrointestinal bleeding and itching.

Previous studies indicated using Bioptron light therapy to accelerate wound healing, it can be used as mono therapy. or as complementary therapy for wound healing and treating pain, Also, it can improve microcirculation, harmonize metabolic processes, reinforce the human defense system, stimulate regenerative processes of the entire organism, promote wound healing and relieve pain.

As a non-invasive intervention for wound healing, it enhances the whole individual's regenerative and reparative processes, promote wound healing, regulates vascular endothelial growth factor (VEGF). It also provides faster wound closure, enhanced wound epithelialization and greater scar tensile strength.

To our knowledge, there were few previous studies investigated and confirm the effect of Bioptron light therapy on wound healing in patients with diabetic wound and burn wound.

But until now there is no previous study investigates its effect on post cesarean section wound healing. so, this study will be the first one in this issue. Therefore, the results obtained from this study will be of valuable benefits for medical service organizations and increase body of knowledge of physical therapists in scientific field.
