BIOFEEDBACK THERAPY IN PELVIC
FLOOR DISORDERS

What is Pelvic Floor Biofeedback
Therapy?



Pelvic floor biofeedback therapy is a type of physical
therapy that can help men and women to learn how to
contract and relax the pelvic floor muscles.
It can be useful for patients who have bladder or bowel
incontinence, slow urination caused by abnormal pelvic
muscle contraction,and pelvic floor dysfunction.
Patients usually spend 3 sessions a week for 1-2 months
with a therapist who is specially trained in pelvic floor
therapy.
How does pelvic floor biofeedback
therapy work?



Pelvic floor biofeedback therapy works by training the brain
and pelvic muscles to work together to tighten and relax the
pelvic floor muscles.
Sensors in the vagina or rectum measure the contraction and
relaxation of the muscles and patients get visual cues on a
computer monitor so that they can learn to better use these
muscles.
In many cases women have tried “Kegel” exercises to
strengthen the pelvic muscles without success, but they have
not been contracting the proper muscles or they have been
contracting them in an improper manner. Many of these
women will have more improvement following pelvic floor
biofeedback therapy.

Biofeedback units generally provide either
visual or auditory feedback relative to the
quantity of electrical activity
Visual feedback uses lights, bars, or analogue
or digital meters
Auditory feedback uses increasing or
decreasing tones, buzzing, beeping or clicking
SEMG artifacts
Line interference (50/60Hz noise)
EKG Artifacts
Movement artifacts
SEMG signal analysis
Baseline or resting level: the level of SEMG
when the muscle is totally relaxed. It is
generally accepted that the SEMG of a muscle
at rest should be below 5μV.
 Averaged contraction (mean of SEMG during
contraction): this is a good indicator of the
level of muscle strength and endurance (while
performing an isometric contraction).
 Peak or maximum: this is the maximum SEMG
amplitude the muscle can generate.
 Variability: is a good indicator of the
neuromuscular stability.

SEMG signal analysis
SEMG recording of a healthy muscle.



Resting level is low
onset and release are quick
and the contraction is high
SEMG unhealthy muscle



The resting level is too high
The level of contraction is very low
The muscle shows instability
