The Association between Chronic Hemodialysis and Toe Pinch Force in Japanese Patients: Cross-Sectional Study

The purpose of this cross-sectional study was to investigate the effect of chronic hemodialysis on toe pinch force (TPF). A total of 37 chronic hemodialysis patients without type 2 diabetes mellitus (T2DM) (age: 69.4 +/- 11.8 years, duration of hemodialysis: 3.5 +/- 3.4 years) were enrolled in this study. The TPF in chronic hemodialysis patients without T2DM was compared with that in 34 apparently healthy participants and 37 chronic hemodialysis patients with T2DM. There was no significant difference in clinical profiles between healthy participants and chronic hemodialysis patients with and without T2DM. The TPF in chronic hemodialysis patients without T2DM was lower compared with that in healthy participants (2.70 +/- 1.05 kg vs. 3.34 +/- 0.99 kg, p = 0.025). In addition, the TPF in patients with T2DM was even lower compared with that in patients without T2DM (2.12 +/- 1.01 kg vs. 2.70 +/- 1.05 kg, p = 0.042). This study showed a dramatic reduction in TPF in chronic hemodialysis patients, especially in those with T2DM.
