## Overview The multifidus muscles are deep segmental stabilizers of the cervical spine. Atrophy or dysfunction of these muscles reduces joint stability, proprioception, and fine motor control of the neck. It is commonly associated with facet joint osteoarthritis, chronic pain, or disuse, and can contribute to ongoing stiffness and compensatory issues. ## Causes Facet joint pathology, nerve-root irritation, chronic pain inhibition, and prolonged immobilization or poor posture lead to multifidus atrophy. The muscle attaches directly to the joint capsules, so joint disease and muscle loss reinforce each other. ## Diagnosis Palpation reveals focal concavity or reduced muscle bulk in the deep cervical region. Ultrasound can measure cross-sectional area. Clinical signs of instability or pain support the finding. ## Treatment Targeted rehabilitation with dynamic mobilization exercises (carrot stretches, baited stretches), resistance-band work, and gradual strengthening rebuild the multifidus. Concurrent treatment of underlying joint disease is essential. ## Recovery and Prognosis Muscle size and function can improve with consistent exercise. Underlying osteoarthritis may limit full resolution. ## Prevention Regular neck mobility work and early treatment of cervical pain help maintain multifidus health.
