There still remains a loophole in clinically diagnosing lumbar canal stenosis. Quantitative muscle ultrasound is useful for evaluating secondary axonal degeneration in chronic inflammatory demyelinating polyneuropathy. We measured the thickness of EDB, abductor hallucis brevis (AHB) and tibialis anterior (TA) muscles in 80 healthy volunteers with ultrasound and assessed EDB CMAP with fibular nerve stimulation.

Dissociated small hand muscle atrophy in amyotrophic lateral sclerosis : frequency, extent, and specificity. There are earlier reports in cases of spina bifida or tethered cord syndrome where late manifestation has led to EDB weakness. Difference in normal limit values of nerve conduction parameters between Westerners and Japanese people might need to be considered when diagnosing diabetic polyneuropathy using a Point-of-Care Sural Nerve Conduction Device (NC-stat/DPNCheck). We also stressed on the need of standing full-length lateral radiographs of the spine to check for sagittal balance of the patients which has a bearing of increasing instability after performing procedures such as laminectomy.
