To develop a classification scale for manometry of pelvic floor muscles (PFM) in Brazilian women, according to the modified Oxford scale.
A cross sectional study, with 288 women enrolled in the Maternity, Natal, Brazil. Manometry and PFM strength data were collected and classified according to the modified Oxford scale. A simple linear regression was performed to determine the classification scale of manometry using the modified Oxford scale as the explanatory variable and the arithmetic mean of the manometry measurements as the response variable.
The average age was 52.80 (±8.78; CI: 51.67-53.93) years. Manometry showed an average of 35.1 (±22.7; CI: 32.1-38.0) cmH2O and most women (29.7%) scored grade 3 on the modified Oxford scale. According to the proposed scale, values between 7.5 to 14.5 cmH2O correspond to very weak pressure; 14.6 to 26.5 cmH2O represent weak pressure; 26.6 to 41.5 cmH2O represent moderate pressure; 41.6 to 60.5 cmH2O represent good pressure, and values above 60.6 cmH2O correspond to strong pressure.
Manometry values were rated on a five-point scale. It is possible to rank the pressure levels performed by voluntary contraction of PFM with this new scale.
根据改良牛津量表制定巴西女性盆底肌测压的分类量表。
一项横断面研究，纳入了巴西纳塔尔市妇产医院的288名女性。收集测压和盆底肌力量数据，并根据改良牛津量表进行分类。以改良牛津量表作为解释变量，测压测量的算术平均值作为响应变量，进行简单线性回归以确定测压的分类量表。
平均年龄为52.80（±8.78；置信区间：51.67 - 53.93）岁。测压显示平均值为35.1（±22.7；置信区间：32.1 - 38.0）cmH₂O，大多数女性（29.7%）在改良牛津量表上得分为3级。根据所提出的量表，7.5至14.5 cmH₂O之间的值对应极弱压力；14.6至26.5 cmH₂O代表弱压力；26.6至41.5 cmH₂O代表中等压力；41.6至60.5 cmH₂O代表良好压力，高于60.6 cmH₂O的值对应强压力。
测压值按五分制评定。使用这个新量表可以对盆底肌自主收缩所产生的压力水平进行排名。
