Evaluation of the therapeutic effects of led (λ627 ± 10 nm) on the initial phase of ankle sprain treatment: a randomised placebo-controlled clinical trial

Abstract

Various therapies for the treatment of sprains have emerged as advances occur in biomedical engineering and photobiology. Therapy with coherent and non-coherent light is a treatment modality for various musculoskeletal injuries. The main certified phototherapy benefits are the reduction of nociceptive processes and the modulation of the inflammatory process, among others. The objective of this study was to analyse the changes caused by the use of light-emitting diodes (LED) (λ627 ± 10 nm) with an energy density of 10 J/cm in 40 subjects divided into two groups (20 placebo and 20 LED). All of the volunteers had acute ankle sprains by inversion of grade II treated with the PRICE (protection, rest, ice, compression and elevation) technique and were treated for 6 days with LED therapy and LED therapy turned off (placebo). Pain assessment was performed on the 1st, 3rd and 6th days using the visual analogue scale (VAS) of pain, the McGill Pain Questionnaire and volumetry. The group treated with LED showed statistically decreased pain compared to the placebo group in both the VAS (85.79 vs 55.73%) and McGill questionnaire (83.33 vs 52.52%). The reduction of oedema in the LED group on the 3rd and 6th days after therapy was statistically superior to that in the placebo (p < 0.0001). Based on the results of this study, treatment with LED, using the tested dose, is effective for pain and oedema in the initial phase of ankle sprains.

Effect of aquatic versus conventional physical therapy program on ankle sprain grade III in elite athletes: randomized controlled trial

“…The control group received a conventional physical therapy rehabilitation program constructed by approved by the Clinical Practice Guidelines Linked to the International Classification of Functioning, Disability and Health from the Academy of Orthopedic Physical Therapy of the American Physical Therapy Association [ 26 ] which consisted of; through the first-week means of immobilization were made by bracing and external support [ 1 ], Low-LASER therapy was used for managing the pain [ 11 ], occupational training [ 26 ], lymphatic drainage [ 12 ], therapeutic exercises in the form of active ROM (ankle pumps), active assisted eversion/inversion, stretching exercises [ 7 ] and neuromuscular training through towel curls.…”

Can photobiomodulation therapy (LASER/LED) associated or not with biomaterials accelerate the process of bone repair the lower limbs of rats? A systematic review study

“…PBMT acts on bone repair by accelerating the synthesis of bone matrix due to increased vascularization, osteocyte synthesis, and by the proliferation of FGF-b, stimulating the proliferation of all cell types involved in healing (14)(15). PBMT also shows satisfactory results in other biomedical applications, such as in the treatment of tendonitis (16), musculoskeletal injuries (17), spasticity (18), diabetic ulcers (19), temporomandibular disorder (20), among others.…”

Effects of Therapy with Light Emitting Diode (LED) in the Calcaneal Tendon Lesions of Rats: A Literature Review

“…From these researches, literature review studies have pointed out ideal irradiation parameters and respective therapeutic effects [17, 18]. However, there is only one study of this type with human beings on the use of LED therapy [19], and specifically on calcaneal tendon lesions, there was no in vivo study with human beings. Researches have been developed in animal models.…”
