Indications of !
perineal biofeedback!
(BFB)
Perineal Biofeedback (BFB) is an active therapeutic
technique consisting in the fine and real-time
graphical visualisation (and/or audible emission) of
voluntary muscle contractions/relaxation by the
patient.
The therapeutic aim is the improvement of voluntary
control of the perineal muscles. The patient is
visually (visual feedback) and acoustically (audible
feedback) made aware of the contraction level of its
perineal muscles (pubococcygeus and puborectalis),
acquired by means of a vaginal probe including a
couple of conductive electrodes.
The conscious appraisal of the performed work
determines the effectiveness of the BFB treatment.
We can identify 2 pathological situations each
corresponding to a biofeedback techniques:
3.1 - Recruiting Biofeedback
The patient has a PC test (test of pubococcygeus)
degree 1 or lower , with "recruitment" problems of
perineal muscles. The adopted technique will be
called indeed "recruitment biofeedback."
Despite being very low the acquired signal,
corresponding to the performed contraction, the
level can not even reach the first target of the
smallest range and the patient, through repeated
free contractions, will try to find the "key" for more
effectively recruiting the fibres of perineal muscle,
and attaining the central target.
3.2 - Training Biofeedback
The patient has a PC test (test of pubococcygeus) of
1 or greater, with problems of "control" of perineal
muscles. The patient is able to reach the central
target, even using a medium range (end-of-scale),
but has a poor fine control of muscles such as not
being able to contract "in time" for a sudden
increase in abdominal pressure due to coughing or
an effort. The patient, in this case, is "guided" to
perform multiple contractions of ever-increasing
