Summary

HYPOTHESIS

Null Hypothesis (HO):

There was a non-significant difference in the role of therapeutic ultrasound in comparison with electrical dry needling in chronic low back patients post cesarean-section.

Alternative Hypothesis (HA):

There was a significant difference in the role of therapeutic ultrasound in comparison with electrical dry needling in chronic low back patients post cesarean-section.

Conditions

  • Chronic Low Back Pain (CLBP)
  • Post Cesarean Section Patient

Interventions

Electrical Dry Needling

Patients in the electrical dry-needling received two 30-minute sessions per week for 6 weeks. Twenty minutes of Electrical stimulation targeted active and latent myofascial trigger points in the quadratus lumborum, multifidus, and iliocostalis muscles following MTrP. Needle insertion sites were varied based on the therapist's assessment of MTrP activity. Needles (0.25 mm × 30 mm or 0.30 mm × 40 mm) were sterilized and inserted into the trigger points, reaching the taut bands and causing local twitch responses. Needles were connected to a TENS device generating a low-frequency current (2 Hz) with a pulse duration of 250 μs and a continuous biphasic waveform, set to a "mild to moderate" intensity as reported by the patient. The 10 minutes of stretching of the quadratus lumborum, multifidus, and iliocostal muscles, including seated side stretches, cat-cow, and child's pose, improve muscle flexibility and reduce tension.

OTHER

Ultrasound

In this study, participants received 12 sessions over 6 weeks, each lasting 30 minutes. The therapeutic ultrasound group received 20 minutes of continuous ultrasound using the Enraf Nonius Sonoplus 434 at 1 MHz frequency and 1.5 W/cm² intensity, applied with slow circular movements over the lower back. Treatment duration was calculated based on the area of pain using Grey's formula. Both groups also participated in a semi-supervised exercise program, starting with 10 minutes of stretching exercises for the lower back and abdominal muscles (quadratus lumborum, multifidus, and iliocostal muscles including seated side stretch, cat-cow, and child's pose improve muscle flexibility and reduce tension.) as guided by the physiotherapist. Patients were encouraged to stay active daily, perform exercises correctly, and avoid other pain treatments during the study. After completing the treatment sessions, patients continued the exercise for progress assessment until the follow-up session. (Gocevsk
