“…The height, weight, and body mass index showed no significant difference. The diameters of the cervical nerve roots in the control subjects were similar to the previous study (10) and thicker than the ALS group (Table 2). However, the proportions of the abnormal diameters in the ALS were low (6 -20%).…”

“…Third, although we tried hard to have blinded sonographic evaluation, recognition of ALS is often straightforward and completely blinded evaluation was not possible. Fourth, although our analysis did not show an age -effect on the nerve size, two groups reported slight age effects, especially in the distal part of peripheral nerves (10,15). Because our ALS patients were older than the control subjects, the diagnostic sensitivity could have been underpowered.…”

Sonographic evaluation of cervical nerve roots in ALS and its clinical subtypes

: Morphological assessment of peripheral nerves in amyotrophic lateral sclerosis (ALS) has been available by sonography. Detection of possible axonal atrophy could be important in predicting progression. Research on correlation between sonographic findings and clinical presentation has been sparse. The aim of the study was to assess possible motor axon loss in patients with ALS by sonography and to correlate the imaging features with clinical subtypes. Patients with either definite or probable ALS and control subjects had sonographic evaluation of the cervical nerve roots (C5, C6, and C7). Each diameter and their sums were measured. The ALS patients were classified by their clinical onset and progression (arm-onset, leg-onset, bulbar, and flail-arm variant) and the sonographic features were compared. Overall, the cervical nerve roots were thinner in ALS than in the controls, but the diagnostic sensitivity was low. The patients with arm dysfunctions tended to show thinner nerve roots than those with normal or relatively preserved arm functions. The four ALS subtypes showed similar diameters of the nerve roots. There was no correlation between the disease duration and the diameters of the nerve roots. Sonography of the cervical nerve roots showed axonal atrophy in ALS and potentially reflects subtle arm dysfunctions.

“…Both cases showed normal CSA in the median nerve and in the longitudinal nerve diameters at cervical nerve roots compared with the reference value [13]. However, some of the findings suggested a nerve enlargement: the CSA of the median nerve in Case 1, and the longitudinal nerve diameter at the C7 nerve root in Case 3.…”

Ö ÖZ ZE ET T A Am ma aç ç: : Yüksek çözünürlüklü ultrasonografi (USG) ile üst ekstremite periferik sinirlerin kesit alanlarının (SKA) dominant ekstremite ile ilişkisini saptamaktır. G Ge er re eç ç v ve e Y Yö ön nt te em ml le er r: : Doksan sekiz katılımcının bilateral medyan ve ulnar sinir SKA'ları ön kolda belirlenen ikişer noktadan ve üst kolda radyal SKA'ı belirlenen tek noktadan ölçüldü. Aynı zamanda SKA'ların hastanın yaşı, cinsiyeti, boy, kilosu ve beden kitle indeksi ile korelasyonlarına hem dominant hem de non-dominant ekstremiteden bakıldı. B Bu ul lg gu ul la ar r: : Bütün katılımcılar değerlendirildiğinde ölçüm noktalarında medyan, ulnar ve radyal SKA değerlerinde dominant ve non-dominant üst extremite arasında istatistiksel olarak anlamlı fark bulunmadı (p>0,05). Katılımcıların dominant taraf tüm ölçüm noktalarında SKA değerleri cinsiyet ve boy ile korele bulunur iken (p<0,05), non-dominant tarafta anlamlı bir korelasyon saptanmadı (p>0,05). Erkek katılımcılarda ise dominant ve non-dominant taraf arasında medyan ve ulnar SKA'nın her iki ölçüm noktasında da istatistiksel olarak anlamlı fark tespit edildi. S So on nu uç ç: : Ölçüm noktalarının ve tekniklerin standardize olmaması, var olabilecek asemptomatik hastalıkların varlığı, demografik verilere göre sinir çaplarındaki farklılıklar USG ile periferik sinir ölçümlerinde sınırlamalara yol açmaktadır. Ancak, sinir çapı ile hastalıkların tanısı konulmaya çalışılırken, erkeklerde fiziki kuvvet ile ça-lışmaya bağlı dominant ve non-dominant taraf arasında fark olabileceği mutlaka göz önünde bulundurulmalıdır.A An na ah ht ta ar r K Ke el li im me el le er r: : Yüksek çözünürlüklü ultrasonografi; sinir kesit alanı; periferik sinir; dominant A AB BS ST TR RA AC CT T O Ob bj je ec ct ti iv ve e: : The aim of this study was to determine the relationship between the cross-sectional areas (CSA) of the upper extremity peripheral nerves and the dominant extremity with high resolution ultrasonography (USG). M Ma at te er ri ia al l a an nd d M Me et th ho od ds s: : In 98 participants, the bilateral median and ulnar nerve CSA were measured from the two points on the forearm and the radial CSA on the upper arm from a single point. At the same time, correlations of CSA with age, gender, height, weight and body mass index of the patients were evaluated both dominantly and non-dominantly. R Re es su ul lt ts s: : There was no statistically significant difference between dominant and non-dominant upper extremities in median, ulnar and radial CSA values at the measurement points when all participants were evaluated (p>0.05). CSA values were correlated with gender and height (p<0.05) at all dominant sides of the participants, but there was no significant correlation at the non-dominant side (p>0.05). In male participants, a statistically significant difference was found between both dominant and non-dominant sides of both median and ulnar CSA. C Co on nc cl lu us si io on n: : The lack of standardization of measurement points and techniques, the presence of possible as...
