abstract = "Spinal cord injury (SCI) is commonly associated with devastating
paralysis. This condition also results in cardiovascular autonomic
dysfunction associated with increased mortality from
cardiovascular disease. The purpose of this study was to explore
the differences in cardiovascular autonomic modulation in
individuals with and without SCI. The study included 60
individuals: 30 individuals without SCI, who formed the control
group-CG and 30 individuals with SCI, who formed the SCI
group-SCIG. The latter group was divided into two, one group of
subjects with SCI above the spinal segment T6-SCIG (above T6) and
a group of individuals with SCI below T6-SCIG (below T6). The
subjects were evaluated by linear and nonlinear analysis of heart
rate variability (HRV). The SCIG showed significantly lower square
root of the mean squares differences of successive NN intervals
(rMSSD), number of pairs of adjacent NN intervals differing by
more than 50 ms (pNN50), standard deviation of short-term HRV
(SD1), and high frequency power (HF). Their low frequency power
(LF) in absolute units (ms(2)) was significantly lower and their
normalized units (n.u.) were significantly higher. Their LF/HF
ratio was significantly higher, and sample entropy (SampEn), which
indicates the complexity and irregularity of the NN intervals time
series, was significantly lower compared to the CG. The
differences between the SCIG and CG were derived mainly from the
SCIG (above T6). The correlation test revealed very low values
between each of the parameters evaluated for CG and SCIG. The SCIG
(above T6) showed greater cardiovascular autonomic impairment
compared to SCIG (below T6) and CG. The SCIG (below T6) also
presented some degree of autonomic dysfunction. All parameters,
linear or nonlinear, are suitable to demonstrate the differences
between the SCIG and CG.",
