An experimental rabbit model of traumatic muscular lesion treated using the low-power laser was assessed using histomorphometric and laboratory tests. Twenty adult New Zealand male rabbits were subjected to muscular trauma under general anaesthesia. Four days after trauma, rabbits in A group started a daily laser therapy, while healing occurred spontaneously in group B animals. The following parameters were analysed on muscular samples: qualitative histological aspect and quantitative histomorphometric evaluation of muscular damage and tissue repair. Results showed a better qualitative and quantitative healing process in traumatised muscles treated with the diode Ga-Al-As low-power laser, if compared to muscles where healing occurred spontaneously. The significant results achieved, demonstrated a relationship between traumatised muscular tissues and stimulation properties of the laser device, and the rabbit proved to be a valid experimental animal model for transferring data into clinical practice.
