Adductors are typically associated with what myotome?

• A. L1-L2
• B. L3-4
• C. S1
• D. L2-3

Answer: (D)

Hip adduction is the movement of bringing the thigh toward the midline, performed by the adductor group (adductor longus, brevis, magnus, and gracilis) innervated mainly by the obturator nerve. The nerve roots contributing to these muscles are predominantly L2 and L3, with some contribution from L4. In clinical myotome testing, the adductors align best with the L2-L3 myotome, making that range the most consistent match for hip adduction. The other options map to different movements or later root levels (for example, L2-L3 covers adduction rather than hip flexion; S1 is more about plantarflexion; L3-L4 more commonly relates to knee actions). Thus, the L2-3 myotome is the correct association for hip adductors.
