OBJECTIVE--To evaluate the influence of peripheral neuropathy on body sway
assessed by posturography. RESEARCH DESIGN AND METHODS--The age-matched
study subjects included 10 insulin-dependent diabetes mellitus (IDDM)
patients with peripheral neuropathy (DN), 23 IDDM patients without
peripheral neuropathy (D) according to the San Antonio Consensus Conference
guidelines, and 21 control subjects (C). All subjects with symptoms and/or
clinical signs of postural instability were excluded from the study.
RESULTS--The trace surface was significantly larger in the DN than in the C
and D groups (P < 0.05), and the trace length was longer in the DN than
in the C and D groups (P < 0.01). Mean velocity was faster in the DN
than in the other two groups (P < 0.001). A direct relationship was
found between the parameters of posturography and some parameters of the
nerve conduction velocity. CONCLUSIONS--Diabetic patients with peripheral
neuropathy demonstrate a relative deficit in their ability to maintain
posture. Posturography allows an early disclosure of the failure of
postural control.
