| dc.description.abstract | Chronic venous insufficiency (CVI) is an abnormality of venous system function with
progressive loss of tissue perfusion. The Kinesio Taping® (KT) application technique
has been considered as a new treatment option for CVI, being a possible alternative
for changes in tissue responses. The primary objective of this analysis was to analyze
the acute and chronic effects of KT use on tissue perfusion in women with CVI. To run
this this objective, two studies were performed. Acute effect study 01 through a doubleblind, randomized controlled trial, with a sample of 59 women who had a diagnosis of
moderate-level CVI, randomized to a KT group control (KT placebo) intervention group.
Near Infrared Spectroscopy (NIRS) was placed on the medial gastrocnemius muscle
for assessment of resting tissue perfusion 48h after the first day of evaluation and after
the KT tape application. An evaluation also consisted of performing plethysmographic
examination movements: lower limb height up to 15cm for five minutes, orthostatism
without leg support evaluated, a plantar flexion and followed by ten successive plantar
flexions, in bipodal support. To check how comparisons of pre and post KT data were
used or delta variation for analysis. For comparisons between the intervention and
control groups, the Mann Whitney-U test was performed. Study 2 on chronic effect
using a randomized, double-blind, non-probabilistic clinical trial stratified into groups
according to an IVC clinical clinic and randomly divided into the intervention group with
KT control group (KT placebo). Fifty-five women aged 30 to 79 years with a diagnosis
of CVI were included in the study. Tests were performed at baseline and after twelve
treatment sessions (four weeks). An evaluation was performed with demographic data
collection, tissue perfusion evaluation with NIRS during constant speed walking test,
transport incremental walking test, heel elevation test and plethysmography movement
protocol, in random order. Additionally, data on functional capacity, calf muscle pump
function and pain were applied. As variables were analyzed using the delta of the
variables and compared using the Mann Whitney-U test. Study results 01: Regarding
the acute effect of KT in women with CVI it can be observed that there was no
statistically significant difference in tissue perfusion between the groups. Despite the
absence of statistical significance, the KT group had a 785.7% lower venous retention
than the control group. Results study 02: The chronic effect of KT use in women with
CVI did not promote significant change in tissue perfusion or demographic and clinical
variables, and a statistically significant difference was observed in the variable
IRVA_TE. Conclusion: The acute use of KT in women with CVI was not able to
significantly alter the tissue perfusion of the calf muscles. However, it was possible to
observe important percentage changes to be considered from the clinical point of view.
Chronic use of KT in 12-session women with CVI has not been able to modify
peripheral tissue perfusion of calf muscles, functional capacity, calf muscle pump
function, and pain in women with mildly severe CVI. There was a less pronounced
worsening behavior of outpatient venous retention during treadmill exercise in the KT
group, which needs to be further investigated. | |
