Inclusion criteria

  • TMJ pain and mouth opening limitation after 1 month of facial penetrating wound injury as the wound is fully healed.
  • TMJ pain (in 1 or both joints) after facial penetrating wound injury.

Exclusion criteria

  • Dental diseases
  • Infectious or systemic diseases
  • Pregnancy
  • Malignancy
  • Pacemaker or metal implants
  • Systemic diseases that affect joint function such as rheumatoid arthritis.

Treatment and study plan

Pulsed Electromagnetic Field therapy (PEMFT)

Device

PEMFT was connected to electrical mains supplying 220v. Pair of applicators sized 16x10x3 cm was adjust to be over TMJ, on both sides of the face; the appliance was adjusted to the frequency of 50 HZ and intensity of 90 Gauss. Twelve PEMF treatment sessions of 30 min duration were provided 3 times per week TMJ mobilization techniques and isometric exercises against resistance for muscles of mastication

TMJ physical therapy program

Other

TMJ manual physical therapy program (mobilization and gentle isometric exercises) for 30, 3 times a week, for 4 weeks.

Primary outcomes

  1. Change in the Maximum mouth opening in millimeter (mm) before and after intervention.

    Time frame: Change between baseline and 4 weeks of treatment measures.

    Each participant was asked to open his or her mouth as wide as possible after that the examiner used a digital Vernier caliper to measure the maximum vertical distance from the incisal edge of the upper central incisors to the incisal edge of the lower central incisors at the midline

Secondary outcomes

  1. Change in TMJ pain measured by Visual Analogue Scale (VAS)

    Time frame: Change between baseline and 4 weeks of treatment measures.

    Visual Analogue Scale (VAS) was used to evaluate pain intensity. VAS is a subjective pain measurement method consisting of a straight line of 100 mm on which patients scored their pain intensity where 0 corresponds to no pain and 10 corresponds to the worst maximum pain
