“…The results of our study showed a statistically significantly increased median nerve cross‐sectional area in patients with PD compared to controls, with no statistically significant slowing of median nerve conduction or reduction in the amplitude. Our results differed from those of the previous study by Yucel et al, 10 which showed a significant reduction in the median nerve amplitude in the second finger and a higher incidence of carpal tunnel syndrome in patients with PD compared to controls.…”

“…One previous study described sonographic findings of the median nerve and the prevalence of carpal tunnel syndrome in PD. 10 In that study, carpal tunnel syndrome was more prevalent in patients with PD compared to a control group, and patients with PD had a higher crosssectional area of the median nerve at the wrist, but there was no statistically significant difference between patients with PD and controls. The authors suggested that tremor might be a risk factor for development of carpal tunnel syndrome in PD; however, the correlation between the degree of tremor and median nerve enlargement at the wrist was not investigated.…”

Objectives Tremor is one of the cardinal features of Parkinson disease (PD) and may cause cumulative trauma‐related injury to nerves of the hands. The aim of this study was to assess the electrodiagnostic and sonographic features of patients with PD and to assess the effect of tremor in PD on the median nerve. Methods We studied 31 hands of healthy control participants (n = 16; mean age ± SD, 60.25 ± 14.67 years) and 81 hands of patients with PD (n = 42; 64.95 ± 11.13 years). Motor symptoms were measured by the Unified Parkinson's Disease Rating Scale III. Median nerve conduction studies and sonographic cross‐sectional area measurements were performed in all participants. Results The median nerve cross‐sectional area in patients with PD (10.71 ± 2.79 mm2) was significantly larger than that in the control group (7.40 ± 1.05 mm2; P < .05). However, there was no significant difference in median nerve electrodiagnostic findings between the PD and control groups. The median nerve cross‐sectional area was associated with the severity of the tremor but not with the Unified Parkinson's Disease Rating Scale motor score. Conclusions Tremor in PD is associated with median nerve enlargement but not with impairment of median nerve conduction.

“…As the prevalence of CTS in the general population has been reported to be 125 to 220 per 100000 [12], ratios mentioned above were significantly higher, calling attention to median neuropathy in PD. Similarly, Yucel et al [4] found frequency of CTS as 24.4% electrophysiologically in their study where they reported a larger median nerve cross-sectional area sonographically in the severe PD patients. The anatomical site, wrist, was also evaluated in PD patients sonographically by Yang et al [3] and median nerve cross-sectional area indicating median nerve swelling with edema was found to be larger ( p < 0.05) in concordance with tremor severity due to the cumulative injury.…”

“…Besides being one of the cardinal symptoms of PD, the characteristic rest tremor seen as “pill-rolling” action of the hands has been also accused of being the trigger of the carpal tunnel syndrome because of causing repetitive trauma to the median nerve [3, 4]. Striatal hand and foot deformities occur in varying degrees associated with the disease severity and may cause functional disability also.…”

Background. While increasing evidence suggests comorbidity of peripheral neuropathy (PNP) and Parkinson's disease (PD), the pathogenesis of PNP in PD is still a debate. The aim of this article is to search the core PD symptoms such as rigidity and tremor as contributing factors to mononeuropathy development while emphasizing each individual patient's asymmetric symptom severity. Methods. We studied 62 wrists and 62 elbows of 31 patients (mean age 66.48 ± 10.67) and 64 wrists and 64 elbows of 32 age-gender matched healthy controls (mean age 62.03 ± 10.40, p = 0.145). The Hoehn and Yahr disability scale and Unified Parkinson's Disease Rated Scale were used to determine the severity of the disease. Results. According to electrodiagnostic criteria, we confirmed median neuropathy in 16.12% (bilateral in two-thirds of the patients) and ulnar neuropathy in 3.22% of the PD group. While mean age (p = 0.003), age at PD onset (p = 0.019), and H&Y scores (p = 0.016) were significant, tremor and rigidity scores were not. The comparison of the mean indices of electrophysiologic parameters indicated subclinical median and ulnar nerve demyelination both at the wrist and at the elbow in the patient groups where a longer disease duration and mild tremor and rigidity scores are prominent, remarkably. Conclusion. A disease related peripheral neurodegeneration beyond symptom severity occurs in PD.
