FIG. 1.

Effect of low-level laser light therapy (LLLT) on wire grip test performance after controlled cortical impact. Motor function was assessed using the wire grip test on post-injury days 1, 3, 5, and 7. (A) Motor recovery did not differ between mice treated with 60 J/cm² compared to injured control mice (p=0.35 for group; n=18–20/group). (B) Injured mice treated with 210 J/cm² had no difference in their motor recovery compared to control mice (p=0.85 for group; n=7–8/group). Wire grip performance in all mice improved over the experimental period (p<0.0001 for time).
