Comparator Agent  NIL   NIL 
Intervention  Scapular strengthening exercises  Scapular strengthening exercises strengthen scapular muscles and improve the forward head posture Exercises are 1. Shoulder press 2. One-arm row 3. Press-up 4. Prone abduction with external rotation 5. Prone flexion 6. Push-ups with plus 7. Prone full can at 100 degrees of abduction Prescription Repetitions: 1–5 Sets: 2–3 Frequency: 3 times a week for 4 weeks Intensity: Progresses from low to high Time: 45–50 minutes per session Type of intervention: strengthening exercises 
Intervention  The McKenzie technique   The McKenzie technique is used as a set of exercises for patients with mechanical problems of the spine, posture correction and ensuring that there is maintenance of correct posture, which is a vital characteristic of the McKenzie exercise. Exercises include 1. Chin tucks 2. Head retraction with overpressure 3. Neck extension 4. Neck rotation 5. Neck flexion Prescription Hold time: 5 seconds. 6 Repetitions Frequency: 3 times per week for 4 weeks Intensity: Low to high as tolerated Duration: 15–20 minutes per session Type of intervention: Mobility and mobilisation exercises progression Gradually increase hold time and repetitions.

Brief Summary   Prolonged use of digital devices has led to an increased occurrence of computer vision syndrome. Computer vision syndrome not only causes ocular symptoms but can also cause musculoskeletal issues such as neck pain, forward head posture and upper cross syndrome. Forward head posture can lead to a reduction of craniovertebral angle and reduce the strength of muscles. Mackenzie exercises have been used as a means of treating individuals with spinal mechanical issues and have been proven effective for forward head posture and neck pain. Scapular strengthening exercises are used to strengthen the muscles and have been shown to improve the strength of scapular muscles and improve forward head posture. Our study aims to combine both Mackenzie and scapular strengthening exercises to understand their effects on craniovertebral angle , muscle strength and scapulohumeral rhythm in individuals with computer vision syndrome.
