Item Shear Wave Velocity Measurements of the Median Nerve in Patients on Chronic Hemodialysis(2020) Yalcin, Kadihan; Demir, Bilge Cakar; 32249947; ABC-5286-2020Objectives Chronic dialysis causes changes in the structure of median nerve. This is a risk for the development of carpal tunnel syndrome in patients on dialysis. The aim of the present study was to evaluate the diagnostic capacity of shear wave velocity (SWV) and the cross-sectional area (CSA) to detect the structural changes of the median nerve in patients with end-stage chronic kidney disease on hemodialysis. Methods Twenty-five patients with chronic kidney disease undergoing hemodialysis 3 times per week and 26 healthy controls were included. None of the participants had any signs or symptoms of carpal tunnel syndrome specified according to the criteria of the American Academy of Neurology Practice Parameters. Both patients and controls underwent sonographic and elastographic examinations of the median nerves in both hands to evaluate CSA and SWV values, and they were compared regarding these parameters. Results The mean CSA of the median nerve in the chronic hemodialysis group was significantly higher than that in the control group (12.74 +/- 1.88 mm(2) versus 8.89 +/- 1.45 mm(2); P < .001). The mean longitudinal and axial SWV values in the hemodialysis group (3.86 +/- 0.54 m/s and 3.92 +/- 0.52 m/s, respectively) were significantly higher than those in the control group (2.98 +/- 0.31 m/s and 3.04 +/- 0.31 m/s, respectively; P < .001). Conclusions Patients on chronic hemodialysis had higher mean CSA and SWV values of the median nerve compared with the healthy controls. Structural changes in the median nerve that occur in patients on chronic hemodialysis can be detected by shear-wave sonoelastogrItem Carpal Tunnel Syndrome: Evaluation of the Effects of Low-Level Laser Therapy With Ultrasound Strain Imaging(2019) Tezcan, Sehnaz; Ozturk, Funda Ulu; Uslu, Nihal; Nalbant, Merve; Yemisci, Oya Umit; 0000-0001-7204-3008; 29892976; ABC-5258-2020Objectives To evaluate the efficacy of low-level laser therapy on median nerve stiffness by using strain elastography in carpal tunnel syndrome (CTS). Methods This study included 37 wrists of 34 patients with mild or moderate CTS between January 2016 and August 2016. The control group comprised 17 patients (18 wrists) with CTS who were treated with wrist splinting for 3 weeks. The low-level laser therapy group included 17 patients (19 wrists) with CTS who were treated with a combination of splinting and low-level laser therapy, which was applied 5 times per week for 3 weeks. Clinical assessment scales, including the Symptom Severity Scale (SSS) and Functional Status Score (FSS), were obtained from our database. The cross-sectional area by ultrasound and strain ratio by elastography were studied. The differences in the strain ratio, cross-sectional area, SSS, and FSS between pretreatment and posttreatment periods in the groups were compared by the paired-sample t test. The correlations between changes in the strain ratio and the cross-sectional area, SSS, and FSS were analyzed by Pearson correlation coefficients. Results The control group included 13 women and 4 men, and the therapy group included 14 women and 3 men. In the therapy group, the mean values of the strain ratio, cross-sectional area, SSS, and FSS decreased significantly after laser therapy (P < .001) in contrast to the control group. No significant correlation was observed between the decreasing degree of the strain ratio and the cross-sectional area, SSS, and FSS after laser therapy. Conclusions The strain ratio and cross-sectional area of the median nerve decrease after low-level laser therapy. These changes may be related to the therapeutic effects of low-level laser therapy, such as nerve regeneration and improvement of the vascular supply.
