Deterioration in the function of the sensorimotor system is often seen in
patients with diabetes and could be related to balance impairments. The purpose
of this study was to determine the association between sensorimotor function and
forward reach ability in patients with diabetes. Thirty-one patients with Type 2
diabetes went through a monofilament test of plantar touch-pressure threshold, an
ankle joint reposition test for joint position sense, and a series of strength
tests of the lower leg. These patients also performed the forward reach test in
standing to measure the reach distance and displacement of the center of mass
(COM), using a motion analysis system. Correlational and regressional analyses
were conducted to determine the association between sensorimotor and balance
parameters. It was found that greater reach distance and COM displacement were
significantly correlated with lower plantar touch-pressure threshold and greater
plantarflexion strength. Regression analysis showed that after controlling the
variance in the subject characteristics, plantar touch-pressure threshold was a
significant predictor for reach distance and COM displacement, while
plantarflexion strength was also a significant predictor for COM displacement.
These findings highlight the importance of the assessment of plantar sensitivity
and the need for detailed balance or fall risk assessment for patients with
impaired plantar insensitivity.
