Description

This study aims to compare the immediate and short-term effects of interferential current therapy and conventional transcutaneous electrical nerve stimulation (TENS) with placebo stimulation on pain and postpartum comfort following cesarean section. A total of 54 primiparous women aged 18-40 years will be randomly assigned to an interferential current, TENS, or placebo group. Each intervention will be administered for 30 minutes. Pain intensity at rest and during in-bed activities will be assessed before the intervention, immediately after the intervention, and at 1 and 2 hours after the intervention. Postpartum comfort, treatment satisfaction, anxiety, and depression will also be evaluated.

Interventions

Conventional TENS (Device)
Conventional TENS will be applied for 30 minutes at a frequency of 125 Hz and a pulse duration of 60 microseconds. Four self-adhesive electrodes will be positioned around the cesarean incision. Current intensity will be increased to a strong but comfortable sensory level and adjusted during the session to maintain the same sensation.
Interferential Current Therapy (Device)
Interferential current therapy will be applied for 30 minutes using a fixed frequency of 100 Hz. Four self-adhesive electrodes will be positioned around the cesarean incision in a crossed arrangement. Current intensity will be increased to a strong but comfortable sensory level and adjusted during the session to maintain the same sensation.
Placebo Electrical Stimulation (Device)
The electrodes and stimulation device will be applied in the same position and for the same 30-minute duration as in the active intervention groups; however, no electrical current will be delivered.

Eligibility criteria

Inclusion Criteria: * Women aged 18 to 40 years * Ability to read, write, and communicate in Turkish * Primiparous women * Having delivered a healthy singleton infant by cesarean section * No additional surgical procedure or complication during or after the cesarean section Exclusion Criteria: * Impaired orientation or cooperation * History of systemic disorders, including hyperglycemia or hypertension, gastrointestinal disorders, or urogynecological disorders * Previous abdominal surgery * Neurological, orthopedic, cardiopulmonary, or other health conditions that may prevent mobilization or ambulation * Previous experience with transcutaneous electrical nerve stimulation or interferential current therapy * Contraindications to electrical stimulation, including sensory loss at the application site, dermatological problems or allergic reactions at the application site, or a cardiac pacemaker
