The Connection Between Jaw Position, Posture, and Balance: What Science Says
Recent research suggests that the position of the lower jaw (mandible) plays a crucial role in overall posture and balance. While this may seem surprising, the jaw is closely linked to the musculoskeletal system through the temporomandibular joint (TMJ), cranial nerves, and even muscle chains that extend down the body.
The Science Behind Jaw Position and Posture
Studies have shown that an imbalanced or misaligned jaw can influence head position, neck muscle tension, and spinal alignment. A study published in Clinical Biomechanics found that alterations in jaw position can affect cervical spine posture, leading to compensatory changes in body alignment. When the lower jaw is misaligned, it can cause asymmetrical muscle activity in the neck and shoulders, potentially leading to postural imbalances.
Additionally, research in Gait & Posture has
demonstrated that jaw clenching or dysfunction in the TMJ can impact balance and stability. The study found that participants with TMJ disorders had increased postural sway, suggesting that jaw alignment plays a role in neuromuscular control.
How Jaw Position Affects Balance
The connection between the jaw and balance is likely due to the nervous system’s integration of proprioception (body awareness). The TMJ is closely related to the trigeminal nerve, which interacts with other sensory systems responsible for posture and equilibrium. Dysfunction in the jaw can lead to altered neural input, affecting how the body maintains stability.
