Zhang Y, Liu X, Jia J, et al. - The current study was conducted in People's Hospital of Jiaozuo City, Henan Province, China, from July 2019 to September 2019 to investigate and compare hand function in type 2 diabetes mellitus patients without carpal tunnel syndrome (CTS) and diabetic polyneuropathy [DPN] (CTS−DPN−), patients with CTS without DPN (CTS+DPN−), patients with DPN without CTS (CTS−DPN+), and patients with CTS and DPN (CTS+DPN+). In total, 161 type 2 diabetes mellitus patients (76 women, 85 men) underwent physical examination and electrodiagnostic tests. Patients with type 2 diabetes mellitus who had both DPN and CTS had lower grip and pinch strengths as well as decreased tactile sensation, both of which were associated with poorer hand dexterity.
