The transportation industry is growing rapidly and the most popular mode is overland by road. Traffic accidents are the most direct and serious risk to the lives of Western people. A large number of traffic accidents occur on the roads each year, especially those caused by motor vehicles on motorways and urban ring roads, often resulting in massive loss of life. According to the World Health Organization (WHO), 1.35 million people die each year worldwide.

Whiplash is the most common injury in motor vehicle collisions, affecting 83% of injured people.

The temporomandibular joint (TMJ) is one of the most complex joints in the human body, since in addition to performing functions in dental occlusion, it does so in the neuromuscular system.

Due to the relationship of the neck with the mandible, the main objective of the study is to determine if there is an improvement in pain and functional limitation in general by applying the dry needling technique in the temporomandibular joint musculature.

• Minimum 3 in temporomandibular joint (TMJ) according to Visual Analog Scale (VAS)
• Consent to participate

• Temporomandibular joint (TMJ) or craniofacial surgeries
