Acupuncture effective for TMJ

Patients suffering TMJ (temporomandibular joint disorder) can find relief from acupuncture. Research conducted at the Ribeirao Preto Dental School, Sao Paulo University in Brazil, found that after 3 months of acupuncture, patients with TMJ experienced significantly less pain, increased strength of their bite and decreased EMG activity of the masticatory muscles.

Temporomandibular joint and muscle disorders (TMJ disorders) are problems or symptoms of the chewing muscles and joints that connect your lower jaw to your skull. 17 patients were studied using acupuncture points for TMJ. EMG measures were acquired before and after the treatment. The data collected at rest, protrusion, left and right laterality, and clenching were normalized by maximum voluntary contraction. Maximal bite force in right and left molar regions were also measured.

The researchers found decreased EMG activity at rest, protrusion, left and right laterality, and clenching; as well as increased values of maximal bite force after acupuncture treatment.
