The purpose of this study is to evaluate the clinical results in pain intensity, neck disability, range of motion, endurance deep cervical muscles, forward head position and kinesiophobia through thoracic spine mobility, deep neck muscles and thoracic strength training and pain education protocol versus a thoracic spine mobility, thoracic strength training and pain education protocol in patients with chronic non-specific neck pain.

The cervical spine is the most mobile region of the spine and must be strong enough to support the weight of the skull and thoracic spine is the most stiff region. In addition, patients often catastrophize their pain, it has a major impact on quality of life. Strength deficits of the deep cervical muscles are related to different clinical conditions, such as non-specific neck pain. Training and education protocols can help to improve pain, function, posture and cross-sectional area. However, there are no multimodal protocols in subjects with chronic non-specific neck pain including deep neck extensor and flexor muscles, thoracic spine mobility and pain education.

Inclusion Criteria:

• Non-specific neck pain for at least the last 12 weeks.
• Pain intensity equal to or greater than 4 on the visual analog scale (VAS).
• Mild-moderate disability in the Neck Disability Index.
• Not reaching phase 2 in Craniocervical flexion test.
• Availability and skill to do video calls.
• Understanding Spanish.

Exclusion Criteria:

• Other type of neck pain.
• Previous neck surgery.
• Diagnosed metabolic diseases.
• Red flags (infection, tumors, rheumatic arthritis, or cardiovascular disease).
• History of cardio-respiratory disease that contraindicates high-intensity exercise.
• Fibromyalgia
• Pregnancy
• Physiotherapeuthic treatment continued in the last 3 month.
