Temporomandibular disorders are common in the general population, the myogenic subtype being the most frequent. Central sensitization seems to be present in this pathology, with a decreased pain pressure threshold observed in both local and remote areas. The best evidence-based treatment consists in combining education, manual therapy and therapeutic exercise in both temporomandibular and cervical regions. Aerobic exercise showed to be effective in subjects with chronic pain and central sensitization, by inducing an hypoalgesic effect. However, there isn't investigation about the effects of aerobic exercise in subjects with myogenic temporomandibular disorders and central sensitization. Thus, the aim of the pilot study is to determine if adding aerobic exercise to an effective physical therapy programme is more effective than physical therapy alone to improve pain pressure threshold in subjects with myogenic temporomandibular disorders and suspicion of central sensitization.

• History of TMJ or cervical surgery
• Systemic, rheumatic, metabolic, neurologic, psychiatric, pulmonary diseases or neoplastic malignant
• History of cardiovascular diseases which contraindicate aerobic exercise
• Current orthodontic treatment, splints for bruxism
• Drug addiction, alcoholism
• Pregnancy
• Use of analgesic medication less than 48 hours before each data collection
• Physical therapy treatment during the past three months
