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

Objective: To determine the effectiveness of strength training combined with stretching compared to specific strength training in office workers with chronic neck pain. Methods: A single blind randomized clinical trial will be conducted. Participants will be adult of both sexes with sedentary office work and chronic neck pain. The intervention will consist of a strength training program for the neck and shoulder muscles combined with static stretching of the neck, while the comparison group will only perform strength training. In addition, both groups will receive ergonomics guidelines. Short-term, medium-term, and long-term evaluations will be performed using the Northwick Park Neck Pain Questionnaire (NPQ), Neck Disability Index (NDI), and Tampa Scale of Kinesiophobia (TSK).
