“…These studies can be followed serially for signs of spontaneous recovery. The absence of motor unit action potentials (MUAPs) by 3 months is indicative of a higher grade axonometic injury and associated with poorer prognosis [18]. Electromyography can also be used in preoperative planning and aid in the selection of optimal donor nerves for nerve transfer.…”

Purpose of the Review: Traumatic brachial plexus injuries (BPI) are devastating life-altering events, with pervasive detrimental effects on a patient's physical, psychosocial, mental, and financial well-being. This review provides an understanding of the clinical evaluation, surgical indications, and available reconstructive options to allow for the best possible functional outcomes for patients with BPI.

The diagnosis of degenerative cervical myelopathy can generally be made with a thorough history, physical examination, and spinal imaging. Electrodiagnostic studies, consisting of nerve conduction studies and electromyography, are a useful adjunct when the clinical picture is inconsistent or there is concern for overlapping pathology. Electrodiagnostic studies may be particularly helpful in identifying cases of myeloradiculopathy, when there is combined nerve root and spinal cord injury, both with regards to prognosis and guiding surgical treatment. Electrodiagnostic studies are a useful adjunct for the spine surgeon and should be used when there are features atypical for degenerative cervical myelopathy or when there is suspicion for a concomitant disease process.

“…These findings will evolve over weeks to months, and thus, the timing of electrodiagnostic studies is important to consider. 7 In a suspected case of nerve injury, electrodiagnostic testing with EMG and NCS is not required but can be considered approximately 3 months after nerve injury. Three months should be sufficient time to distinguish the severity of nerve injury and possibly assess the healing potential in less severe, neurapraxic injuries.…”

“…Electrodiagnostic testing is a useful adjunct both for diagnosis of peripheral nerve abnormalities and can be seen as an extension of the clinical examination. [7][8][9] Electrodiagnosis is composed of nerve conduction studies (NCSs) and electromyography (EMG). NCS is done by providing measured electrical stimuli to motor, sensory, or mixed peripheral nerve fibers and then measuring the response.…”

Footdrop is a common musculoskeletal condition defined by weakness in ankle joint dorsiflexion. Although the etiology varies, footdrop is characterized by specific clinical and gait abnormalities used by the patient to overcome the loss of active ankle dorsiflexion. The condition is often associated with deformity because soft-tissue structures may become contracted if not addressed. Patients may require the use of special braces or need surgical treatment to address the notable level of physical dysfunction. Surgical treatment involving deformity correction to recreate a plantigrade foot along with tendon transfers has been used with notable success to restore a near-normal gait. However, limitations and postoperative dorsiflexion weakness have prompted investigation in nerve transfer as a possible alternative surgical treatment.
