Vibrator & Retarded Orgasm investigation

Has anyone tried this? What did you do? What happened? Seems a simple non invasive approach.
Unfortunately the article isn't very clear about the instructions they gave to participants.

Assessment of Penile Vibratory Stimulation as a Management Strategy in Men with Secondary Retarded Orgasm
Christian J. Nelson, Absaar Ahmed, Rolando Valenzuela, Marilyn Parker, and John P. Mulhall

".................... In this study, PVS was an effective treatment for retarded orgasm that increased orgasm functioning and sexual satisfaction within 3 months of the start of treatment. These gains were sustained at the 6-month assessment point."

I read the abstract (just once) and I didn't find it very clear. Were the guys just able to get off with the vibrator or did it cure their anorgasmia for later when doing the nasty with their wife and/or partner without the aid of the vibrator?
