Mulligan SNAG Technique in Individuals With Lumbar Intervertebral Disc Protrusion

Not Applicable

Active, not recruiting

• Conditions: Intervertebral Disc Protrusion
• Interventions: Other: Mulligan SNAG mobilization tecnique; Other: Conventional Physiotherapy

• Registration Number: NCT06521294
• Lead Sponsor: Biruni University

Brief Summary

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.

Detailed Description

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.

Arm && Interventions

Group	Intervention	Description
Group 1	Conventional Physiotherapy	SNAG
Group 2	Conventional Physiotherapy	Physiotherapy
Group 1	Mulligan SNAG mobilization tecnique	SNAG

Primary Outcome Measures

Name	Time	Method
Magnetic Resonance Imaging	baseline and iafter the intervention (in the 5th week)	to measure protrusion (bigger amount means worse outcome)
Visual Analog Scale-VAS	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 Outcome Measures

Name	Time	Method
Functional Independence Measure- FIM	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)
Sit-Stand Test-SST	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)
Oswestry Disability Index-ODI	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)
Nottingham Health profile-NHP	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)
Tampa Kinesiophobia Scale- TKS	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)
10-m Walking test and cadance measurement	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)
One Leg stand Test- OLST	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)
