Professor Byung-Jo Kim's research lab specializes in clinical and diagnostic neurophysiology, with a focus on spinal and peripheral nerve disorders. The lab investigates neuromuscular and sensory processing abnormalities in conditions such as fibromyalgia, radiculopathy, and chronic low back pain, using advanced imaging and electrophysiological techniques. Key research directions include the application of ultrasonography for real-time guidance in epidural injections, evaluation of spinal reflexes like the cutaneous silent period, and establishing normative neurophysiological data for specific populations, including Asians. The lab aims to improve diagnostic accuracy and therapeutic outcomes through precise, non-invasive, and patient-specific approaches.

Although it entails a radiation hazard risk, the use of fluoroscopy during caudal epidural steroid injection has increased to help place the medication more accurately and allowed physicians to maximize the procedure's therapeutic success rate. To investigate the feasibility of using real-time high resolution ultrasonography for guiding the epidural needle into the caudal epidural space and to confirm any vascular intake of medication, we performed color Doppler ultrasonography while medication
The lower extremity nerve CSA values obtained in this study may provide normal reference values for the Asian population.
Paraspinal fibrillation potentials or positive sharp waves (PSWs) reportedly may be the only electrodiagnostic abnormality in patients with radiculopathies. However, spontaneous activity may be present in muscles of asymptomatic subjects. To determine whether abnormal spontaneous activity in the cervical paraspinal muscles is clinically relevant, we evaluated the prevalence of such activity in asymptomatic individuals and examined its relationship with age. Sixty-six asymptomatic subjects underw
The pathogenesis of fibromyalgia (FM) has not been clearly elucidated, but central sensitization, which plays an important role in the development of neuropathic pain, is considered to be the main mechanism. The cutaneous silent period (CSP), which is a spinal reflex mediated by A-delta cutaneous afferents, is useful for the evaluation of sensorimotor integration at the spinal and supraspinal levels. To understand the pathophysiology of FM, we compared CSP patterns between patients with FM and n
