Abstract

Objective

The aim of this study was to explore the relations between toe pinch force and other muscle strength parameters in male patients with type 2 diabetes mellitus.

Methods

A total of 40 men with type 2 diabetes (age: 53.4 ± 13.1 years, duration of diabetes: 8.5 ± 8.1 years) who needed exercise training were enrolled in this cross-sectional study. We evaluated the clinical parameters and 4 muscle strength parameters, which were toe pinch force, handgrip strength, isometric knee extension force, and isometric ankle dorsiflexion force.

Results

The HbA1c, toe pinch force, handgrip strength, isometric knee extension force, and isometric ankle dorsiflexion force were 10.1 ± 2.4 %, 3.2 ± 1.2 kg, 37.3 ± 7.0 kg, 39.6 ± 11.4 kgf, and 17.0 ± 6.3 kgf, respectively. Toe pinch force was significantly correlated with handgrip strength (r = 0.365, p = 0.0206), isometric knee extension force (r = 0.668, p < 0.0001), and isometric ankle dorsiflexion force (r = 0.514, p = 0.0007). All muscle strength parameters were significantly lower in patients with diabetic polyneuropathy than in those without polyneuropathy.

Conclusion

Although toe pinch force was significantly correlated with the other muscle strength parameters, the correlation was not so strong. However, evaluation of toe pinch force might be recommended for assessment of distal limb muscle strength in patients with type 2 diabetes.
