Adaptation of perturbation to postural control in individuals with diabetic peripheral neuropathy.

Loss of sensation in the feet due to diabetic peripheral neuropathy can cause deterioration of postural control and result in higher risk of trips, slips or falls. In the literature, many studies have reported that people with diabetic peripheral neuropathy tend to show greater displacement of body sway than normal people when the base of support is disrupted. But not much is known about postural characteristics of diabetics with peripheral neuropathy at the moment of postural stability disruptions and during the time span for recovering stability. The objective of this study was to analyze differences of postural characteristics between diabetics with peripheral neuropathy and diabetics without peripheral neuropathy. A learning effect of perturbation was found for the diabetic peripheral neuropathy group in the posterior direction of perturbation during the first phase, which may indicate that it could be possible to design a postural control program for those people.
