The effect of laser and ultrasound on local bloodflow
In a study conducted on 12 healthy females the effect of laser and ultrasound on local bloodflow was investigated. Laser and ultrasound were administered to the right thigh of the same individual with an interval of one week. Local bloodflow was measured at the outset, during application and every 10 minutes (for 30 minutes) after application, by means of a plethysmograph. Despite the restrictions of the small sample size it would appear that only laser resulted in an increase in bloodflow, particularly 20 minutes after application.
