Objective:
This study aimed to assess the diagnostic utility of optically pumped magnetometer-based magnetoencephalography (OPM-MEG) in patients with cervical spondylotic myelopathy (CSM).
Methods:
A total of 31 CSM patients and 32 healthy volunteers were enrolled. Somatosensory-evoked magnetic fields (SEFs) were recorded using OPM-MEG. Clinical evaluations included the Japanese Orthopaedic Association (JOA) scale and the Short Form-36 (SF-36) health survey. Diagnostic performance was evaluated using receiver operating characteristic (ROC) analysis.
Results:
Compared with healthy controls, CSM patients demonstrated decreased α power in the occipital region, and increased γ power in the occipital, temporal, and frontal regions. Significant differences in phase locking value (PLV) were observed in the α band between the occipital-frontal regions. The latency of the maximum SEF was 49.66 ± 5.51 ms in healthy controls and 58.63 ± 7.73 ms in CSM patients. ROC analysis for SEF latency yielded an area under the curve of 0.844, with a cutoff value of 55.0 ms, sensitivity of 77.4%, and specificity of 81.3%.
Conclusion:
MEG may a helpful tool in the functional assessment of the neurological deficits in CSM, and shows potential as an useful method for clinical diagnosis and functional evaluation of this condition.

Take an ideal inductor with zero resistance. Although it's practically impossible, assume that the coil's resistance is so small that it is practically negligible. The loss of the field's energy to dissipate thermal energy (or heat) is thus...

Consider a point charge moving with a constant velocity. Like the electric field, the magnetic field at any point is directly proportional to the magnitude of the charge and inversely proportional to the square of the distance between the source point and the field point. However, unlike the electric field, the magnetic field is always perpendicular to the plane containing the line...
