FUNCTIONAL REACH TEST: MOVEMENT STRATEGIES IN ELDERLY AND DIABETIC NEUROPATHIC SUBJECTS
Functional Reach (FR) is a simple clinical measure
developed by Duncan et al. in 1990 to estimate the
dynamic balance in the elderly at risk of recurrent
falls. FR has been defined as the maximal distance
one can reach forward beyond arm’s length while
maintaining a fixed base of support in the standing
position [Duncan, 1990]. Previous works showed as
FR is not able to differentiate healthy elders from
individuals with balance impairments [Wernick-
Robinson, 1999]. More information can be obtained
from this motor task if it can be described looking
at the kinematic behaviour [Cavanaugh, 1999] and
at the motor strategies employed. The purposes of
this study is to describe the principal parameters
that characterized the FR test in elderly and diabetic
neuropathic subjects, and to investigate the
presence of different movement strategies used by
these two categories of subjects
Nonlinear dynamic and regularity of postural sway in diabetic subjects with peripheral neuropathy.

Approximate entropy on posturographic data of diabetic subjects with peripheral neuropathy.
Posturographic time series (stabilogram) analysis is characterized by the difficulty to show the nature (deterministic or stochastic) of this
signal. However, recent studies have shown a nonlinear chaotic behaviour
of the stabilogram . Because of the intrinsic complexity of the stabilogram, the aim of this work is to analyze posturographic data without anyconsideration on their dynamics and to investigate their behaviour in terms of regularity and complexity. These latter characteristics can be useful to
find differences, due to pathological conditions, in the signals dynamics.
The variations of regularity and complexity in physiological signals can
be revealed by Approximate Entropy (ApEn) . In this work ApEn has been evaluated for stabilograms related to diabetic subjects with Peripheral
Neuropathy and to diabetic control subjects
