Comparative Study on SNAG From Different Positions Low Back Pain Treatment

patients will receive SNAGs from standing (Loaded-SNAG), step-stance, or functional position that provokes symptoms. A specialized Mulligan belt was used around the patient's waist and the therapist's hips. The mobilizing force was applied parallel to the facet joint plane (cephalic direction) and over the spinous processes of the respective symptomatic spinal levels. The therapist's hand's ulnar aspect was used over the spinous process of the superior vertebra of the involved segment for flexion glide. The therapist applies accessory glide to targeted zygapophyseal level while the patient actively performs symptomatic movement (e.g., forward flexion), performing repetitions with the therapist maintaining the glide.

patients will receive unloaded SNAG from quadruped position to reduce the axial loading. The therapist applies the equivalent accessory glide at the symptomatic spinal level while the patient performs the symptomatic movement (modified to be non-weight-bearing).
