Considering its important role in rotation and abduction of the lower extremity the piriformis has the potential to dramatically alter distal lower extremity biomechanics. Prior to this study no research had shown a relationship between LBP or lower limb injuries and the Piriformis muscle.
Results of the study showed that LBP affected the Piriformis muscle CSA during the playing season, suggesting that the presence of LBP during the season may affect the muscles ability to respond to the athlete’s physical demands. Furthermore, it was shown that players with a relative smaller CSA had higher odds of sustaining a severe lower limb injury during the playing season.
Taken together, the authors have shown that a motor control program can positively affect the CSA of the Piriformis muscle. With enhanced motor control training showing a reduction in the lower limb injuries it is likely there is an enhancement in control of the entire kinetic chain.
