17The Ultimate Guide to Red Light TherapyA third study examined infrared laser treatment for foot pain in classical ballerinas.46Eight adult femaledancers received bi-weekly laser treatments for three months. Researchers measured foot temperature, painsensitivity, and balance.Resultsshowedincreasedfoottemperature,reducedpainsensitivity,andimproved balance on the support foot after treatment.46 The findings suggestinfrared laser therapy may help relieve pain and enhance performance in balletdancers, possibly due to increased blood flow. While promising, more extensiveresearch is needed to confirm these initial results and explore long-term effects.2.1.5 RLT and Hand ConditionsA study explored the benefits of LED (light emitting diode)RLT for a painful hand condition called tenosynovitis,which is inflammation of the tendon sheaths (protectivecoverings around tendons—strong, fibrous tissues thatconnect muscles to bones—helping them move smoothlyas you bend and stretch your joints).47 The study focusedon people whose hand pain hadn‘t improved with typicaltreatments like anti-inflammatory pills.Twelve people received LED light therapy twice a weekfor a month.47 Researchers measured pain, stiffness,andtendonhealthusingvariousmethods,includingultrasound images (pictures of the inside of the bodycreated using sound waves) and lab tests on tendon cells.The results were positive.47 Participants reported significantly less pain and stiffness over time. Ultrasoundimages hinted at improved tendon health, though the results weren‘t conclusive. Lab tests showed that theLED light therapy increased the production of the protein collagen, which is important for tendon health.Importantly, there were no harmful side effects.Resultsshowedincreasedfoottemperature,reducedpainsensitivity,andimproved balance on the support foot after treatment.46 The findings suggestinfrared laser therapy may help relieve pain and enhance performance in balletdancers, possibly due to increased blood flow.
