Comparison of cross‐sectional areas and distal‐proximal nerve ratios in amyotrophic lateral sclerosis

Comparison of cross‐sectional areas and distal‐proximal nerve ratios in amyotrophic lateral sclerosis

ABSTRACT Introduction: This study explored potential diagnostic markers of nerve ultrasound in differentiating amyotrophic lateral sclerosis (ALS) from mimic disorders. Methods: Ultrasound of the median, ulnar, and tibial nerves was conducted in 53 patients with ALS, 32 patients with ALS‐mimic disor...

Zusammenfassung:ABSTRACT Introduction: This study explored potential diagnostic markers of nerve ultrasound in differentiating amyotrophic lateral sclerosis (ALS) from mimic disorders. Methods: Ultrasound of the median, ulnar, and tibial nerves was conducted in 53 patients with ALS, 32 patients with ALS‐mimic disorders, and 30 controls. Nerve cross‐sectional area (CSA) and distal–proximal ratios were calculated. Results: The median nerve CSA in the upper arm was decreased (7.9 ± 1.3 mm2 vs. 9.0 ± 1.4 mm2, P
