This French research group has set out to objectively
measure the increased pressure generated by the ischiocavernosus (IC) muscle
during erection. Several papers have proposed that PFM exercises can improve
erectile dysfunction (ED) through the following mechanism - stronger PFM,
specifically the IC muscle, provides pressure at the base of the penis so that
blood is maintained in the penis and erection is maintained. This paper has a much more scientific explanation. Study was observational - no control group or
variations in treatment groups. Patients
were seen weekly (up to 20 sessions) and received
·
Penile injection of prostaglandin E1 to induce
erection· Electrical stimulation to the dorsal penis 80 Hz, 30 minutes
· Isolated, voluntary IC muscle exercises - they are not specific as to how they are sure it is an isolated contraction or the instructions given to achieve an isolated contraction. Results state there were a median of 318 to 312 "pressure peaks per session". Not sure if this means they did over three hundred IC contractions?
Results show increase in pressure as a result of training
over 80% with a conclusion that "pelvic floor muscle rehabilitation was
found to be beneficial in erectile dysfunction".
Firstly I think it is wrong to make this conclusion when
penile injections where also given. Do
we know if weekly penile injections will improve penile pressures?
