Sex-Specific Muscle Activity Patterns During Gait After ACL Rupture (pmc.ncbi.nlm.nih.gov)

• Males and females show different muscle activity during gait after ACL rupture.
• Males activate rectus femoris and hamstrings more; females activate gastrocnemius and gluteus medius more.
• Sex-specific rehabilitation protocols may improve outcomes and reduce re-injury.

"A study reveals that males and females exhibit distinct muscle activity patterns during gait after anterior cruciate ligament (ACL) rupture. These findings enable chartered physiotherapists to tailor rehabilitation protocols based on sex. Surface electromyography data from multiple lower limb muscles showed significant differences in coordination, suggesting that rehabilitation should incorporate sex-specific exercises to optimize neuromuscular control and reduce re-injury risk."
