Muscular trauma treatment with the diode laser: An experimental in vivo study in rabbit.

An experimental rabbit model of traumatic muscular lesion treated using the low-power laser was assessed using histomorphometric and laboratory tests. Twenty adults New Zealand male rabbits were subject to muscular trauma und er general anaesthesia. Four days after trauma, rabbits in A group started a daily laser therapy, while healing occurred spontaneously in group B anim als. The following parameters were analysed on muscular samples: qualitativ e histological aspect and quantitative histomorphometric evaluation of musc ular damage and tissue repair. Results showed a better qualitative and quan titative healing process in traumatised muscles treated with diode Ga-Al-As low-power laser, if compared to muscles where healing occurred spontaneous ly. The significant results achieved, demonstrated a relationship between t raumatised muscular tissue and stimulation properties of the laser device, and the rabbit proved to be a valid experimental animal model for transferr ing data into clinical practice.
