This real or perceived traumatic event that could happen before, during, or following labor and delivery could be toward the baby, mother, or both. These traumatic events could include, but are not limited to unplanned c-section, death, the baby going into the NICU, the use of the vacuum extractor, or forceps during delivery, lack of support and/or reassurance during the delivery (from friends, family, and/or the medical staff), or any other severe physical complication or injury related to childbirth such as preeclampsia, or an unexpected hysterectomy.Conclusions have been made related to the idea of childbirth stressors and the contribution those can play in an increased risk of developing comorbid birth-related posttraumatic stress disorder and postpartum depression rather than only a postpartum depression diagnosis. Findings like the one mentioned above are crucial in accurate diagnosis to provide the mothers with the most appropriate and effective treatment options, and to advance the validity and reliability of preventative assessments and strategies. Other studies have been able to identify obstetric and perinatal risk factors associated specifically with birth-related posttraumatic stress disorder including educational level, gestational age at delivery, number of prenatal care visits, pregnancy intervals, mode of delivery, any complications with pregnancy, and labor duration.
The semitendinosus and the semimembranosus share their origin with the long head of the biceps, and both attaches on the medial side of the proximal head of the tibia together with the gracilis and sartorius to form the pes anserinus. The semitendinosus acts on two joints; extension of the hip, flexion of the knee, and medial rotation of the leg. Distally, the semimembranosus tendon is divided into three parts referred to as the pes anserinus profondus. Functionally, the semimembranosus is similar to the semitendinosus, and thus produces extension at the hip joint and flexion and medial rotation at the knee. Posteriorly below the knee joint, the popliteus stretches obliquely from the lateral femoral epicondyle down to the posterior surface of the tibia. The subpopliteal bursa is located deep to the muscle. Popliteus flexes the knee joint and medially rotates the leg. Lower leg and foot
With the popliteus (see above) as the single exception, all muscles in the leg are attached to the foot and, based on location, can be classified into an anterior and a posterior group separated from each other by the tibia, the fibula, and the interosseous membrane. In turn, these two groups can be subdivided into subgroups or layers—the anterior group consists of the extensors and the peroneals, and the posterior group of a superficial and a deep layer. Functionally, the muscles of the leg are either extensors, responsible for the dorsiflexion of the foot, or flexors, responsible for the plantar flexion.
