High Intensity Laser Therapy vs. ultrasound therapy Research Question The research question for this article is whether high-intensity laser therapy or ultrasound (US) therapy is more beneficial for the short-term treatment of subacromial impingement syndrome (SAIS). Little evidence has been found on the effects of physical therapy treatment, with some studies showing the effectiveness of ultrasound therapy and others showing limited effectiveness in this type of condition. Literature review According to Cameron, laser therapy increases collagen production and decreases inflammation, while hindering bacterial growth. It also promotes vasodilation so that blood and other nutrients can flow to the area. An indication for the use of laser therapy includes soft tissue healing, which would be beneficial in the treatment of SAIS. Cameron also states that “laser therapy has been associated with an increase in collagen synthesis, rate of wound healing and closure, tensile strength, tensile stress, number of degranulated mast cells, and a reduction in healing time. healing.”2 This article also examined the benefits of US therapy. in patients with SAIS. According to Cameron, “The thermal effects of ultrasound include accelerating metabolic rate, reducing or controlling pain and muscle spasm, altering nerve conduction velocity, increasing circulation, and increasing extensibility. soft tissue.”2 Ultrasound applies electrical current to the area to be treated through a crystal in the transducer. The duration of the ultrasound depends on the total area to be treated and a longer duration increases the amount of energy transmitted to the tissue. Ultrasound can reach deeper tissues better than other types of physical agents. If the pur......middle of paper......therapy clinics and I will probably use it more during my practice. I will examine the area to be treated, taking into consideration the various contraindications and precautions, and I will begin my therapeutic session. Although I believe this is a beneficial intervention, if it shows any progress now, I will look into other types of modalities to help treat my patient. Works Cited1.
