PFM activity was monitored by surface electromyography during the combination of isotonics technique of four pelvic patterns of PNF\u2010concept (i.e., anterior elevation, posterior depression, anterior depression, and posterior elevation). The electromyographic signal was analyzed using root mean square amplitude.
