Different Laser Frequencies on Neuropathic Outcomes in Patients With Bell's Palsy

Обзор

this study was done to compare different laser frequencies on neuropathic outcomes in patients with Bell's palsy.

Подробное описание

This study aims to compare the efficacy of different laser irradiation wavelengths (808 nm, 980 nm, and 1064 nm) in treating facial nerve lesions, which can lead to paralysis and impaired facial movement. The findings are expected to inform clinical decisions, enhance treatment outcomes, and improve rehabilitation protocols for patients with Bell's palsy, ultimately aiming to enhance their quality of life.

Вмешательства

• Устройство sham laser therapy
  the laser irradiation will be deactivated in the sham laser device by its manufacturer, but its visual light and acoustic functions maintained. The output power of the sham laser's infrared light will be zero mW, will be applied over the eight points over the face
• Устройство Low-Level Laser Therapy
  Low-Level Laser Therapy (LLLT) for 5 min over eight points over the face, with the laser probe in direct contact with the superficial roots of the facial nerve. The parameters will be used wavelength of 830 nano meter, frequency of 1 kilohertz, the duty cycle of 80%, and energy density of 10 J/cm'. During each session, the total energy will be delivered to the patient are 80 Jole.
• Устройство gallium arsenide diode laser (BTL-5000 laser)
  gallium arsenide diode laser (BTL-5000 laser) will be used with infrared probes of 830 nm wavelength and 100 mW output power, average energy density of 10 J/em?, a frequency of 1 kilohertz, and a duty cycle of 80 %. In all cases, the laser will be in direct contact with the superficial roots of the facial nerve on the affected side and will be applied for 2 min and 5 s per point for 8 points with a total energy of 80 J
• Устройство high intensity laser treatment
  High intensity laser therapy treatment with pulsed neodymium doped: yttrium aluminum garnet laser. The apparatus provided the following options: pulsed emission (1,064 nm), very high peak powers (3 kW), high levels of fluency (energy density) (810-1,780 mJ/cm), brief duration (120-150 Ms), low frequency (10-40 Hertz), and a duty cycle of approximately 0.1 %. High intensity laser therapy will be applied with contact and perpendicular to the superficial roots of the facial nerve of the affected si
• Другое Exercises
  Patients in all treatment groups received massage to the facial muscles and facial exercises. The facial exercises may include different facial expressions in front of mirror, applying a resistance to the sound side to reinforce the weakened side. A resisted exercise to the neck muscles was performed in all direction to encourage the movement of the facial muscles as neuromuscular facilitation exercises for facial muscles
