Mulligan Mobilization Techniques for Non-Specific Low Back Pain

Condition(s) studied

Investigational drug(s) / intervention(s)

Hip Internal Rotation Mulligan Mobilization: Mulligan mobilization applied to hip internal rotation using a mobilization belt. Performed in 3 sets of 10 repetitions, twice weekly for 4 weeks, in addition to conventional physiotherapy.

Straight Leg Raise Mulligan Mobilization: Mulligan mobilization applied to straight leg raise under manual traction. Performed in 3 sets of 10 repetitions (15-20 seconds hold), twice weekly for 4 weeks, in addition to conventional physiotherapy.

Conventional Physiotherapy: Conventional physiotherapy including transcutaneous electrical nerve stimulation (20 minutes), massage, lumbar stretching and strengthening exercises, postural training, and patient education. Delivered twice weekly for 4 weeks.

Study summary

This study aims to compare the effectiveness of two different Mulligan mobilization techniques in patients with non-specific low back pain. A total of 30 adults with chronic low back pain will be randomly assigned to three groups: (1) conventional physiotherapy plus hip internal rotation Mulligan mobilization, (2) conventional physiotherapy plus straight leg raise Mulligan mobilization, or (3) conventional physiotherapy only. The interventions will be applied twice a week for four weeks. The main outcomes are pain intensity (measured by Visual Analog Scale) and lumbar range of motion. Secondary outcomes include disability level (Oswestry Disability Index) and back awareness (Fremantle Back Awareness Questionnaire). The study will help determine whether Mulligan techniques provide additional benefits beyond conventional physiotherapy in reducing pain and improving function in people with non-specific low back pain.

Eligibility

Primary outcome measure(s)

• Pain Intensity (Visual Analog Scale, VAS) — Baseline (week 0) and post-treatment (week 4).
  Pain intensity will be assessed using the Visual Analog Scale (VAS), a 100 mm horizontal line ranging from "no pain" to "worst pain imaginable." Participants will mark their pain level, and the distance in millimeters will be recorded.
• Lumbar Range of Motion (ROM) — Baseline (week 0) and post-treatment (week 4).
  Lumbar spinal range of motion will be measured using a goniometer. Participants will perform active forward flexion, and the angle of motion will be recorded in degrees.
