Effectiveness of Specific Strength Training Combined With Static Stretching of the Posterior Neck in Office Workers With Chronic Neck Pain: A Clinical Trial

The intervention will consist of specific strength training composed of 5 exercises performed with dumbbells: front raises, lateral raises, reverse flies, shoulder shrugs, and wrist extensions. In addition to the following static stretches: stretching towards lateral flexion of the upper part of the trapezius muscle, the scalene muscles, and the sternocleidomastoid muscle on both sides; extension of the extensor muscles; flexion of the flexor muscles; and contralateral flexion and rotation combined with scapular depression of the scalene muscles and elevation of the scapula on both sides, holding each stretch for 10 seconds. This sequence of stretches will constitute one set, with 6 sets performed with a 30-second rest between sets, lasting 8 minutes. Therefore, the intervention will have a total duration of 28 minutes per session, conducting 3 sessions per week.
