Biomechanical and histological analysis of the gastrocnemius in rats subjected to muscle injury and treatment with low-level laser therapy

What the authors concluded

The mean values for the maximum force were: 35.70 (...) N in [control group], 31.77 (...) N in [muscle lesion group] and 34.36 (...) N in group [muscle lesion + laser group], with a statistically significant difference between [control and muscle lesion groups] (p < 0.05)." "Laser therapy had a positive effect on the regeneration process of the muscle injury.
