Evaluate the Effect of Dry Needling on the Temporomandibular Joint in Subjects Who Have Suffered a Whiplash as a Result of a Traffic Accident

Randomized, Open Clinical Trial to Evaluate the Effect of Dry Needling on the Temporomandibular Joint in Subjects Who Have Suffered a Whiplash as a Result of a Traffic Accident

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.

It is a minimally invasive treatment modality. Its effectiveness has been confirmed in numerous studies. It consists of applying an antiseptic in the puncture area and inserting the needle in the required aseptic conditions. During puncture, the patient's physical response is observed at all times, in order to control the local spasmodic responses in each muscle. After applying the technique, we assessed jaw pain, mouth opening, and the appearance of headaches. The adverse effects of the technique are the following: pain after puncture (1.7%), local bleeding at the puncture site (6.1%) and syncopal responses (0.7%).

Determine pressure in kg in the masseter, temporal, and pterygoid muscles with an algometer to obtain 5/10 in Visual Analog Scale (VAS) to all participants

Obtain pain from 1 to 10 in the masseter, temporal, and pterygoid muscles according to the Visual Analog Scale (VAS) after applying the pressure obtained with the algometer in the previous step. *Patients in the experimental group are evaluated 10 minutes after the application of dry needling
