Effects of Mulligan Mobilization With and Without Sling Exercises in Non-specific Neck Pain

Overview

Neck pain is one of the common musculoskeletal problems. People with neck pain can have difficulties with daily activities and be limited in work and social participation. Main symptoms of people with neck pain include pain, decreased range of motion (ROM), muscle weakness and dysfunction. Common neck pain causes include degenerative disc disease, herniated disc disease, cervical radiculopathies, myofascial pain syndrome and viral infections. Muscular strains, postural and ergonomics are also related to neck pain and whiplash injuries. The onset of pain may be insidious or may follow trauma, and it may be recurrent or persistent in nature. Ideally, the pain goes away in 1-3 weeks, but in some cases it persists and become chronic neck pain. The aim of this study is to compare the effects of mulligan mobilization with and without sling exercises on pain, and disability in non-specific neck pain. Non-specific neck pain reduces range of motion which may be linked to mechanical restriction between two or more vertebrae and muscular spasm.

Participants who will meet the inclusion criteria will be recruited by convenience sampling technique and will be allocated to groups by simple randomization process by sealed opaque enveloped labeled as 1 for Group A and 2 for Group B. After taking consent from the participants with non-specific neck pain of both genders will be randomized into two equal groups. Subjects from physical therapy department will be assessed with neck disability index, goniometer and Numeric pain rating scale. At start of study, a formal educational session, lasting about 30 min will be given by physiotherapist. Group A: In this group, Subjects will be treated with Mulligan mobilizations along with sling exercises. Mulligan mobilizations include SNAGs. Participants will receive 3 sets of mulligan mobilization techniques per session, each set involving 10 times repetition of the exercise. The interval between the sets will be 15 to 20 seconds. The technique will be repeated total of six times having two sessions per week for 3 weeks. For the sling exercise, the sling exercise program will also be applied for 3 weeks, 2 times a week for 20 minutes per day. To perform the exercise, the subjects will be instructed with a demonstration and explanation. In supine position, the head will be supported by an inelastic sling and the therapist will hold the cervical vertebral portion softly with two hands. Therapist will pull the cervical vertebral portion and back of the head softly. The subjects will maintain this for 6-7 seconds and relax slowly. In the second technique, Subjects will be positioned in supine lying position with the cervical spine in a neutral position on the sling device. One hand of the therapist contacts and fixes the transverse process of C1 (both), while the other hand grabs the occiput and applies mobilization in the dorsal direction. Subjects in this group will be applied with passive mobilization for 3 min to the segment (occiput-C1). In the same posture the subjects will be instructed to perform a flexion motion at (occiput-C1). The therapist will guide the optimal segmental movement through the hand. This intervention will also be performed 3 times for 1 min, with an interval of 1 min. Similarly, In prone position the forehead will be placed on an inelastic sling. The therapist will hold the cervical vertebral portion with two hands softly. The therapist will pull the cervical vertebral portion toward the upper direction at the same time. The patient will maintain this for 6-7 seconds and relax slowly. Each movement will be repeated 10 times
