What would you think if I said he has noticed a protruding shoulder blade during pullups? A long thoracic nerve injury? A brachial plexus […]

Case Study: Lumbar Radiculopathy

Recently a patient was referred to us with possible Lumbar radiculopathy. Emory Healthcare defines lumbar radiculopathy as a disease involving the lumbar spinal nerve root. This can manifest as pain, numbness, or weakness of the buttock and leg. Dr. Martinos performed an electromyograph (EMG) on the patient to learn more about the cause of this issue […]
