Abstract:
|
Localized bioimpedance (BIA) was
measured with a single frequency phase-sensitive
analyzer at 50 kHz in three post-traumatic types of
injuries on four professional soccer players: (1) myositis
ossificans, (2) intramuscular seroma and (3) trochanteric
(hip) bursitis. Normal reference value (no injury) was
obtained from the contra lateral not injured limb at a
mirror-like location of the injury. The relative variations
resistance (R) and reactance (Xc) at the time of injury
was confronted with the not injured values. Relative
variations between acute measurements and post
medication ones on intramuscular seroma and bursitis
have been computed. In intramuscular seroma and
trochanteric bursitis we have obtained a percent of
change between injury data and after medical
intervention. On myositis ossificans, localized BIA
showed a 7-8 % decrease in Xc whereas the percent of
change of R was negligible (1 %). These percent of
changes are in concordance with histological evidence. In
the case of a presence of seroma or the lower thigh and
trochanteric bursitis, the soft tissue cavity accumulates
fluid. Post-injury localized BIA, relative with respect to
non-injured side, confirmed sizeable soft tissue
destruction evidenced by 50 % decrease of Xc and 24-31
% decrease of R due to interstitial fluid accumulation.
Once the seroma and the blood in the bursitis was
removed the localized the immediate post-injury BIA
parameters increased as follows: a) intramuscular
seroma + 10 % on R and + 74 % of Xc; b) trochanteric
bursitis + 20 % of R and +24 % of Xc. Localized BIA
other than classifying soft tissue injuries, can be useful to
understand the pathophysiology and structural
impairments of other kind of injuries and to understand
their behavior. |
