A loss of sensation in the lower limbs, observed in individuals with
diabetes as well as elderly individuals, contributes to postural instability,
altered gait patterns, increased risk of falling, and decreased quality of life.
OBJECTIVE: To determine if somatosensory cues delivered to sensate areas of the
lower limbs above the ankle joints enhance the control of posture in individuals
with peripheral neuropathy. METHODS: Twelve subjects with sensory neuropathy due
to diabetes participated in static and dynamic balance tests with and without
auxiliary sensory cues provided to the lower limbs without stabilizing the ankle
joints. During the tests the subjects were required to stand on a fixed or moving
computer-controlled platform with their eyes open or closed. Equilibrium scores
and response latency were obtained. RESULTS: For all tests, equilibrium scores
were significantly larger in experiments with auxiliary sensory cues in
comparison with conditions without cues (P < .05). Smaller latency scores were
recorded in conditions with auxiliary sensory information. The results indicate
that auxiliary sensory cues improved automatic postural responses. CONCLUSIONS:
The observed enhancement of automatic postural responses has clinical
implications that aid in the understanding of postural control in individuals
with peripheral neuropathy. Future controlled trials could examine whether
devices that provide auxiliary sensory cues can improve balance, mobility, and
the performance of daily activities.
