Muscle Energy Versus Mulligan Techniques in Treating Patients With Cervical Spondylosis

Overview

This study will be aimed to answer the following questions: Which technique, MET or MMT, is more effective in reducing pain, increasing range of motion (ROM), improving proprioception, and enhancing functional ability in individuals with CS? It will be assumed that: 1. All participants will adhere to study instructions and procedures. 2. All participants will be evaluated under standardized conditions.

Cervical spondylosis (CS) is a highly prevalent age-related condition (95%), that affects the joints and discs of the cervical spine. By age 65, nearly all individuals experience some degree of degeneration, characterized by disc breakdown and enlarged facet joints. While aging is the primary cause, injuries can accelerate this process in younger populations. Significance of the Study Age-related degenerative spinal changes are almost widespread. Population-based studies have shown that approximately 80 to 90% of people have disk degeneration on magnetic resonance imaging (MRI) by the age of 50 years. A global burden review estimates that over 300 million people worldwide had mechanical neck pain lasting at least 3 months in 2015. Clinical features of spondylosis are more common in men than in women, with a peak incidence between the ages of 40 and 60 years for both men and women. Cervical spondylosis commonly affects the middle and lower cervical vertebrae (C5-C6 and C6-C7), although higher levels may also be involved. Neck pain is the most prominent symptom. CS can affect all cervical components (i.e., the spinal cord, spinal vasculature, and nerve roots). Cervical spondylosis Symptoms include cervical instability (abnormal movement or laxity between vertebrae). This instability can lead to various symptoms such as neck pain, muscle imbalance between cervical and shoulder girdle muscles (weakness in cervical flexors, lower trapezius, and anterior serratus; tightness in the upper trapezius, scapular lift, and pectoralis major), disc herniation and osteophyte formation. These can compromise proprioception (accurate sensory feedback) and limit neck mobility, significantly impacting function and daily activities. Muscle energy techniques is a form of manual therapy frequently used by physical therapists to improve musculoskeletal function and alleviate pain. MET aims to adjust abnormal muscle tone by training specific muscles, enhancing strength and stability, improving the musculoskeletal function, and ultimately improving quality of life. Another treatment technique is MMT that is now an integral component of many manual physiotherapists' clinical practice. MMT involves sustained passive accessory force/glide to a joint while the participant actively performs a problematic movement. This study aims to address this gap in knowledge by investigating whether MET or MMT is more effective in improving pain, ROM, proprioception, and functional ability in individuals with cervical spondylosis. The findings from this study can provide valuable insights for physical therapists in selecting the most appropriate treatment approach for their patients with cervical spondylosis. By determining the more effective technique, physical therapists can optimize treatment plans and potentially improve patient outcomes. This Triple-blinded (the examiner, statistician, and the participants will be blinded, while the therapist will be aware of treatment procedures) randomized controlled trial (RCT) will investigate the effectiveness of Muscle Energy Techniques (MET) compared to Mulligan Mobilization Techniques (MMT) on cervical spine pain, ROM, and function in participants with Cervical Spondylosis (CS). The study will be conducted at the outpatient physical therapy clinic of Horus University in New Damietta, Egypt.
