Mulligan SNAG Technique in Individuals With Lumbar Intervertebral Disc Protrusion

This study aimed to examine the effects of the Mulligan SNAG mobilization technique, applied in addition to conventional physiotherapy on the structure of the intervertebral disc and physical functioning in patients diagnosed with low back pain due to lumbar intervertebral disc protrusion. 38 volunteer patients will participate in the study. The participants will be randomized as an interventional and control gropus.

About this study

Participants will be treated 3 days a week for 4 weeks. The session duration will be 40-45 minutes. Visual analog scale-VAS, oswestry disability index, magnetic imaging-MRI assessment, functıonal independence scale-FIM, Tampa kinesiophobia scale, one leg stand test, sit-stand test, 10-meter walking test, cadence , Nottingham health profile will be used to assses the participants in the two groups. All participants will be evaluated in the 5th week of the study. The program includes physical therapy session (Hot packed, trans cuteneal electric stimulation, therapeutic ultrasound, and therapautic exercises) and the Mulligan SNAG mobilization technique.

Primary outcomes

  1. Magnetic Resonance Imaging

    Time frame: baseline and iafter the intervention (in the 5th week)

    to measure protrusion (bigger amount means worse outcome)

  2. Visual Analog Scale-VAS

    Time frame: baseline and immediately after the intervention (in the 5th week)

    to measure pain intensity (min. score is 0 and max. score is 10- higher score means worse outcome)

Secondary outcomes

  1. Oswestry Disability Index-ODI

    Time frame: baseline and immediately after the intervention (in the 5th week)

    to describe disabilty level resulting from pain (min. score is 0 and max. score is 50- higher score means worse outcome)

  2. Functional Independence Measure- FIM

    Time frame: baseline and immediately after the intervention (in the 5th week)

    to measure independency in daily living activities (min. score is 18 and max score is 156- higger score means better independency in daily living activities)

  3. Tampa Kinesiophobia Scale- TKS

    Time frame: baseline and immediately after the intervention (in the 5th week)

    to measure anxiety-avoidance state (min. score is 17 and max. score is 68- higher score means worse outcome)

  4. One Leg stand Test- OLST

    Time frame: before and after the intervention (in the 5th week)

    to measure static balance ability (min. score 0 and max. score is 60- Higher score means better balance)

  5. Sit-Stand Test-SST

    Time frame: before and after the intervention (in the 5th week)

    to measure lower extremity performance (min. score is 0 and max. score is 30- higher score means better outcome)

  6. 10-m Walking test and cadance measurement

    Time frame: before and after the intervention (in the 5th week)

    to measure walking speed (in second- higher score means worse outcome) and cadance (number of steps during the test- higher score means better outcome)

  7. Nottingham Health profile-NHP

    Time frame: before and after the intervention (in the 5th week)

    to describe level of quality of life (min. score is 38 and max. score is 3800 - higher score means poor health)
