Light-emitting diode therapy increases collagen deposition during the repair process of skeletal muscle.
RatOtherWistarMaleTranscutaneous irradiation over the injured tibialis anterior muscleWavelength 850 nm, output power 30 mW, total energy 3.2 J p…Applied after cryoinjury, with assessment at 1, 3 and 7 days
Model: Cryoinjury of the tibialis anterior muscle induced by two applications of a metal probe cooled in liquid nitrogen
LED therapy at 850 nm significantly reduced inflammatory infiltrate at 3 days, increased the number of immature muscle fibres at 7 days, reduced MMP-2 gelatinolytic activity at 1, 3 and 7 days, and increased collagen deposition at 3 and 7 days compared with untreated injury.
