Ultrasound is widely used in rehabilitation, primarily for improving connective tissue extensibility and pain relief in musculoskeletal injuries, and for promoting tissue healing and remodeling. Physiotherapists use therapeutic ultrasound more than any other electrophysiological modality, Topical analgesics will activate superficial thermal response receptor, providing hot or cold sensation, topical agents suspended in aqueous gel are more effective in transmitting ultrasound energy, compared to cream-based agents which are less effective, to transmit sound waves, there must be a gel between the ultrasound probe and the skin, Topically applied external analgesics do appear to provide some benefit of pain relief, the active ingredient in most of these is menthol, methyl salicylate, or a combination of the two, menthol is the irritant that do produce a cooling sensation while methyl salicylate do provide a sensation of heat, Aloe vera is one of the plant material known to effectively decrease inflammation and promote wound healing. This brings to a conclusion that Aloe vera was having potential analgesic activity and that can be used in this study.
