Synergistic muscle activation intensifies a woman’s ability to contract the PFM. In some cases, even for continent women, it is not possible to fully contract their PFM without involving the synergistic muscles. The primary aim of this study was to assess the surface electromyographic activity of synergistic muscles to PFM (SPFM) during resting and functional PFM activation in postmenopausal women with and without SUI.Materials and methods: This study was a preliminary, prospective, cross-sectional observational study and included volunteers and patients who visited the Department and Clinic of Urology, University Hospital in Wroclaw, Poland. Forty-two patients participated in the study and were screened for eligibility criteria. Thirty participants satisfied the criteria and were categorized into two groups: women with SUI (n=16) and continent women (n=14). The bioelectrical activity of PFM and SPFM (AM, RA, GM) was recorded with a surface electromyographic instrument in a standing position during resting and functional PFM activity.Results: Bioelectrical activity of RA was significantly higher in the incontinent group than in the continent group. These results concern the RA activity during resting and functional PFM activity. The results for other muscles showed no significant difference in bioelectrical activity between groups.Conclusion: In women with SUI, during the isolated activation of PFM, an increased synergistic activity of RA muscle was observed; however, this activity was not observed in asymptomatic women. This may indicate the important accessory contribution of these muscles in the mechanism of continence.

Women and the information society: barriers and participation

Paper presented to the Women’s Is-sues Section of IFLA at the 68th IFLA General Conference, held in Glasgow, Scotland, from 18–24 August 2002. Reviews the literature on the topic of women, the information society and the Internet. Also presents selected results of Masters’ research projects undertaken in the Department of Information Science at Loughborough University, United Kingdom. Discusses female access to the Internet and explores some of the barriers that may prevent women having the same access as men. Examines differences in male and female Internet use. The negative aspects of the Internet for women are very often emphasized, but there are positive reasons for women to use the Internet and advantages to this method of computer-mediated communication for women. The concept of Cyberfeminism is discussed. Concludes that although there are negative sides to the technology, women must engage with the Internet if they are to help shape the Information Society
