AimTo调查市售的阴道内探头，旨在记录肌电图（EMG）从骨盆底肌肉（PFMs），并讨论目前technology.MethodsThe MEDLINE EMBASE，CINAHL，PEDRO和科克伦数据库的优势和局限性进行了搜索的文章中，阴道内探头被描述为已被用来记录肌电图从PFMs。还使用Google搜索引擎搜索万维网，以查找用于记录来自PFM的EMG的设备。最后，联系了一家加拿大阴道内探针分销商，以确定通过其他方法无法识别的阴道内EMG探针。通过制造商或其网站确定每个探头的规格，并由研究者获取每个器械以验证规格和电极配置。对记录EMG data.ResultsSixteen不同型号的市售阴道内探头的国际标准进行了评估的设备：7个从发表的研究论文，7个使用万维网，和两个通过与分销商的通信。探针的形状，尺寸，电极定位，和电极配置不同，许多设计容易记录运动伪影，串扰，和/或不适当的EMG signal.ConclusionAll市售的阴道内探针有缺陷，在他们的设计，如探针的几何形状，电极的大小，位置，和/或配置的问题。应开发改进的阴道内EMG探头用于研究和临床实践。Neurorol。Urodynam。34：104-112，2015.

AimTo survey commercially available intravaginal probes designed to record electromyography (EMG) from the pelvic floor muscles (PFMs), and to discuss the strengths and limitations of current technology.MethodsThe MEDLINE EMBASE, CINAHL, PEDRO, and Cochrane databases were searched for articles in which intravaginal probes were described as having been used to record EMG from the PFMs. The World Wide Web was also searched using the Google search engine to find devices used to record EMG from the PFMs. Finally, a Canadian distributer of intravaginal probes was contacted to identify intravaginal EMG probes not identified through other methods. The specifications of each probe were determined through the manufacturer or their website, and each device was acquired by the investigators to verify the specifications and electrode configuration. The devices were evaluated against international standards for recording EMG data.ResultsSixteen different models of commercially available intravaginal probes were identified: seven from published research papers, seven using the World Wide Web, and two through communication with a distributer. The probes vary in shape, dimensions, electrode positioning, and electrode configuration, with many designs prone to recording motion artifact, crosstalk, and/or inappropriate EMG signals.ConclusionAll commercially available intravaginal probes had deficiencies in their design such as problems with probe geometry, electrode size, location, and/or configuration. Improved intravaginal EMG probes should be developed for use in research and clinical practice. Neurourol. Urodynam. 34:104-112, 2015. (c) 2013 Wiley Periodicals, Inc.
