Which myotome pattern corresponds to hallux extension?

The myotome pattern that corresponds to hallux extension is L5. This specific level of the lumbar plexus innervates the muscles responsible for extending the big toe, or hallux. In the context of anatomical structures and nerve root distributions, the extensor hallucis longus muscle, which is primarily responsible for this movement, is predominantly innervated by the L5 nerve root.

Understanding myotomes is essential for assessing the integrity of the nervous system in patients, particularly in relation to neurological examinations or rehabilitation settings. The L5 nerve root also plays a role in the sensory distribution of the medial aspect of the foot, contributing to the clinical evaluations of both motor and sensory functions in this region. This connection explains why the accurate identification of L5 is crucial for effective assessment and treatment in athletic training and rehabilitation practices.
