To compare the efficacy of interferential current therapy versus narrow band ultraviolet B radiation in the treatment of post herpetic neuralgia.
Forty nine patients suffering from distressing post herpetic neuralgia. assigned randomly into 2 groups; interferential group and narrow band ultraviolet B group. Intensity of pain was recorded before and after therapy using numerical rating scale.
The results of this study showed no significant difference in pain intensity post treatment between both groups in acute and subacute neuralgia as p value > 0.05 while there was significant difference between both groups in established neuralgia as p value< 0.05.
The study concluded that interferential current and narrow band ultraviolet B were effective in acute and subacute neuralgia, while only interferential is effective in established neuralgia.
