biofeedback
Perineal Biofeedback (BF) 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 silicone balloon integrated in a special
vaginal probe.
The conscious appraisal of the performed work
determines the effectiveness of the BF 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
the 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
