Sa1680 EFFECTS OF CONCENTRIC PELVIC FLOOR RESISTANCE EXERCISES ASSOCIATED WITH BIOFEEDBACK ON ISOMETRIC MUSCLE CONTRACTIONS OF THE ANAL SPHINCTER

ABSTRACTThe professional literatures on the development of widely practiced procedure, episiotomy through theyears from the first publication in 1742 are reviewed. It reveals the change in number of publication as wellas the contributors to the development of perception about episiotomy. So it consisted expression of opinionof doctors initially then the co-workers like nurses and researchers and clients or consumers themselvestoo. It concludes that episiotomies prevent anterior perineal tear but fails to accomplish other benefitstraditionally ascribed to pelvic floor damage and relaxation including its sequel and also protection ofnewboin from intracranial haemorrhage and intrapartum asphyxia. Episiotomy substantially increasematernal blood loss during delivery and risk of anal sphincter damage with their long term morbidity.There is an urgent need to restrict the use of episiotomy in vaginal delivery.Key Words: Episiotomy, Perineal tear, anal sphincter damage.

The effect of creatine (Cr) supplementation on muscle isometric torque generation and relaxation was investigated in healthy male volunteers. Maximal torque (Tmax), contraction time (CT) from 0.25 to 0.75 of Tmax, and relaxation time (RT) from 0.75 to 0.25 of Tmax were measured during 12 maximal isometric 3-s elbow flexions interspersed by 10-s rest intervals. Between the pretest and the posttest, subjects ingested Cr monohydrate (4 × 5 g/day; n = 8) or placebo ( n = 8) for 5 days. Pretest Tmax, CT, and RT were similar in Cr and placebo groups. Also in the posttest, Tmax and CT were similar between groups. However, posttest RT was decreased consistently by ∼20% ( P < 0.05) in the Cr group from the first to the last of the 12 contractions. In addition, the mean decrease in RT after Cr loading was positively correlated with pretest RT ( r = 0.82). It is concluded that Cr loading facilitates the rate of muscle relaxation during brief isometric muscle contractions without affecting torque production.

Pelvic floor disorders are strongly associated with childbirth and are more prevalent in parous women. Pelvic floor trauma commonly occurs at the time of the first vaginal childbirth. Conventionally, childbirth trauma refers to perineal and vaginal trauma following delivery and the focus has been on the perineal body and the anal sphincter complex. However, childbirth trauma may involve different aspects of the pelvic floor. Pelvic floor trauma during vaginal childbirth may involve tissue rupture, compression, and stretching, resulting in nerve, muscle, and connective tissue damage. Some women may be more susceptible to pelvic floor trauma than others due to collagen weakness. Childbirth trauma affects millions of women worldwide. The incidence of perineal trauma is over 91% in nulliparous women and over 70% in multiparous women. A clinical diagnosis of obstetric anal sphincter injury (OASIS) is made in between 1% and 11% of women following vaginal delivery. Increased training and awareness around OASIS is associated with an increase in the reported incidence. Short- and long-term symptoms of childbirth trauma can have a significant effect on daily activities, psychological well-being, sexual function, and overall quality of life.
