Brief Summary:
Spinal cord injuries have become increasingly frequent due mainly to the increase in urban violence. The growing number of automobile collisions and violence-related events merits particular attention, as such occurrences can lead to death or disability stemming from a spinal injury. The severity of the consequences depends on the location affected and degree of destruction of afferent and efferent spinal cord pathways, with higher, more extensive injuries leading to less physical fitness and functional independence. Unfortunately, injured neurons of the central nervous system are unable to regenerate following a spinal injury and spinal cord regeneration is therefore a major challenge to researchers in the fields of neuroscience and neurologia. Upon receiving an external stimulus, the central nervous system is believed to adapt and reorganize itself using mechanisms to compensate for neuronal loss and promote, even if partially, the remodeling of remaining synaptic connections, leading to new neuronal sprouting. Low-level laser therapy (LLLT) has proven to be a possible option for the stimulation of the repair process in the central nervous system. It is plausible that this type of therapy can offer the same benefits previously established in other types of tissues, the stimulation of bone formation, neovascularization and the regeneration of peripheral nerves. Research groups have investigated the efficacy of LLLT for the treatment of spinal cord injuries and have demonstrated that laser therapy administered simultaneously to an injured sciatic nerve and corresponding segment of the spinal cord accelerates the regeneration process of the injured peripheral nerve.

Arm Intervention/treatment
Experimental: low-level laser therapy

The treatment group will receive LLLT following the protocol outlined below:

LLLT protocol - radiance will be administered to the injury site transcutaneously at a wavelength of 808 nm using a Twin Flex Evolution diode laser (MMO Equipamento Opto-Eletronicos, Brazil). Twelve sessions will be held (three per week over four weeks). The dose administered to the surface of the skin will be 983 J/cm2 per session, with a treatment area of 4.72 W/cm² and total radiant energy of 25 J. According to the literature, this dose is capable of enhancing functional recovery following an injury.
