Comparison Between Magnetic Field and Laser Therapy in Management of Trigeminal Neuralgia

Study Overview
=================
Brief Summary
-----------------
Trigeminal neuralgia (TN) was defined by The International Association for the Study of Pain (IASP) as severe, sudden, usually unilateral, stabbing, brief, recurrent attacks of pain in one or more distributional branches of the trigeminal nerve. The purpose of the current study will to investigate the effect of Low level laser therapy versus electromagnetic therapy on diabetic trigeminal neuralgia pain intensity and amplitude of the compound muscle action potential of the masseter and temporalis muscles in diabetic TN patients.

Official Title

Magnetic Field and Laser Therapy in Management of Diabetic Trigeminal Neuralgia

Conditions
-----------------
Trigeminal Neuralgia

Intervention / Treatment
-----------------
* Other: Electromagnetic therapy.
* Other: Low level laser therapy (LLLT)


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: All participants will between the ages of 25 and 45, will of both sexes (male and female), diabetic type two patients with chronic trigeminal neuralgia, (from three to six months). Patients will awake, cooperative, and free of psychiatric issues (as determined by a psychologist) as well as difficulties resulting from orthopaedic or special sensory deficits. Exclusion Criteria: Patients will ruled out if they developed TN due to a tumour, herpes zoster, or any other reason other than diabetes, such as significant coagulation dysfunction, cardiopulmonary dysfunction or previous invasive treatment (ethanol, radiofrequency, Gama-knife microvascular decompression, glycerinum injection). They will not have a previous disability in the face.

-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Studies using electromyography and complex muscle action potentials | All patients' compound motor action potential amplitudes in the masseter and temporalis muscles will be evaluated before interventions. | at the beginning of the study | 
| Studies using electromyography and complex muscle action potentials | All patients' compound motor action potential amplitudes in the masseter and temporalis muscles will be evaluated after two month of interventions. | by the end of successful two month of intervention | 
| Visual analogue scale (VAS) | All the participants were instructed to express their pain by Visual analogue scale (VAS) before the interventions. | at the beginning of the study | 
| Visual analogue scale (VAS) | All the participants were instructed to express their pain by Visual analogue scale (VAS) after two month of interventions. | by the end of successful two month of intervention |
