About this trial
This study is designed as a crossover trial. All participants who meet the inclusion criteria and voluntarily agree to participate will be evaluated using the assessment methods detailed below. Subsequently, participants will be randomly assigned into two groups. The first group (Mulligan Concept Group - MCG) will receive the SNAG technique, while the second group (Neural Mobilization Group - NMG) will perform the Sciatic Nerve Mobilization Exercise (SNME). After the intervention, participants will be evaluated a second time. Ten days after this session, participants will be invited back. Those who were in the MCG group during the first session will be re-evaluated and then receive the SNGE intervention. Participants who were in the SNGE group during the first session will be re-evaluated and then receive the SNAG intervention. Following this second intervention, participants will be evaluated once again.
Assessments will be done are Demographic Form, Visual Analogue Scale, Oswestry Disability Index, Joint Range of Motion, Five-times Sit-to-stand Test, Sit and Reach Test

Treatments tested in this trial
Sustained Natural Apophyseal Glide (SNAG)
Other interventionIn this intervention, participants will initially receive the SNAG technique targeting the L5-S1 lumbar segment. Participants will be seated on a treatment table with feet flat and knees at 90°. The therapist will position a specialized Mulligan belt around the L5-S1 segment and anchor it around their pelvis to generate a gentle traction force via controlled hip movement. While this force is applied, participants will perform active trunk flexion, holding the end-range position for 30 seconds. This movement will be repeated six times, constituting a 3-minute set. A total of 4 sets will be administered, with 2-minute rest periods between sets.
Sciatic Nerve Mobilization Exercises (SNME)
Other interventionParticipants will sit with hips and knees at 90° flexion, feet flat on the floor. The involved leg will be fully extended at the knee. In this position, the participant will be asked to perform ankle dorsiflexion and neck extension simultaneously (applying tension to the distal part of the sciatic nerve while relaxing the proximal part) and hold for 3 seconds. Next, the participant will plantarflex the ankle and flex the neck (tensioning the proximal end while relaxing the distal), again holding for 3 seconds. This 6-second sequence will be repeated 10 times per set. The exercise will be performed in 3 sets per leg, with 3-minute rests between sets.

Trial outcomes
Primary outcomes
1
Oswestry Disability Index (ODI)
The ODI assesses the impact of sciatic nerve pain on daily activities, including sitting, standing, walking, sleeping, and personal care. The total score indicates the level of disability.
Time frame
Through study completion, an average of 1 year2
5 Times Sit to Stand Test
The test will be used to measure the time it takes for an individual to rise from a seated position and sit back down. The participant is prepared in a seated position on a standard chair with a height of 43-46 cm, with their back against the chair and arms crossed over the chest. Upon the command to begin, the participant stands up fully and then completes the test by sitting down and standing up a total of five times as quickly as possible.
Time frame
Through study completion, an average of 1 year3
Sit and Reach Test
The participant will sit on a mat placed on a flat surface, with legs extended straight forward and knees fully extended. The soles of the feet will be positioned vertically and kept stable. The participant will then reach forward with both arms, aiming to touch the toes or reach beyond them if possible. The reach distance will be recorded in centimeters based on how far the fingertips are from the soles of the feet.
Time frame
Through study completion, an average of 1 yearSecondary outcomes
1
Range of Motion
Spinal flexion, extension, and lateral flexion range of motion (ROM) will be assessed using a goniometer. The patient will be prepared in an upright standing position, with feet shoulder-width apart, arms relaxed at the sides, and maintaining a straight posture. Then the function will be done by the patient actively.
Time frame
Through study completion, an average of 1 year2
Pain Intensity Visual Analog Scale (VAS)
Pain intensity will be evaluated using the Visual Analog Scale (VAS), where participants rate their pain from 0 (no pain) to 10 (worst imaginable pain). Pain will be measured during sitting, forward bending, and walking, for both back and leg pain.
Time frame
