Rehabilitation continues to evolve with the increased emphasis on patient management and proprioceptive training. Proprioception can be defined as a specialized variation of the sensory modality of touch that encompasses the sensation of joint movement (kinesthesia) and joint position (joint position sense). Numerous investigators have observed that(More)
OBJECTIVE The high incidence of noncontact anterior cruciate ligament (ACL) injuries in females has attracted research to investigate the capacity of muscles to reflexively protect the knee joint from capsuloligamentous injury. Numerous reflex pathways link mechanoreceptors in the ACL with contractile fibers in the quadriceps and hamstring muscles. Loads(More)
OBJECTIVE Underlying the ability of the hamstrings to decrease tibial anterior shear is the time of firing in comparison with the quadriceps. This timing may be aided by neural programming during a planned or expected activity. It is theorized that individuals who have better programming ability will suffer fewer anterior cruciate ligament (ACL) injuries(More)
Context: Muscle fatigue is an important concept in regard to the muscle function of the shoulder joint. Its effect on the muscle force couples of the glenohumeral joint has not been fully identified. Objective: To examine the effects of muscle fatigue on muscle force-couple activation in the normal shoulder. Design: Pretest, posttest. Patients: Ten male(More)
A woman had an unusual müllerian anomaly with a septate uterus, cervical duplication, and longitudinal vaginal septum. Gynecologists should be aware of the possibility of cervical duplication associated with uterine septum and not didelphic uterus, as this disorder in a patient with infertility or recurrent miscarriages can be treated surgically by(More)
Rehabilitation continues to evolve with the increased emphasis on patient management and proprioceptive training. Proprioception can be defined as a specialized variation of the sensory modality of touch that encompasses the sensation of joint movement (kinesthesia) and joint position Goint position sense).

The purpose of this study was to compare electromyographic (EMG) activity of the abdominal muscles between the crunch exercise and five other popular abdominal exercises. Surface EMG recordings of four muscles (upper rectus, lower rectus, external oblique, and internal oblique) of the anterior abdominal wall were collected and analyzed on 20 healthy, male(More)
BACKGROUND The purpose of this study was to compare the training effects of the Ab-Flex (F), Ab-Roller (R) and standard crunch (C) on EMG production, isometric maximum voluntary contraction (MVC), and isokinetic average peak torque at 30 degrees/sec (ISO) of the abdominal muscles. It was hypothesized that the training devices would have similar value in a(More)
OBJECTIVE(S) To determine the levels and pattern of inhibin B secretion during ovarian stimulation in patients with endometriosis and to evaluate the correlation between inhibin B levels and variables of follicular and oocyte development. DESIGN Retrospective cohort study. SETTING IVF center. PATIENT(S) Women with endometriosis (n = 20) and tubal(More)
This review covers the clinical presentations, treatments, and outcomes of cornual heterotopic pregnancies reported in the literature. Infertile women with a history of ectopic pregnancy, tubal surgery, or disease are at increased risk for cornual heterotopic pregnancy when they undergo in vitro fertilization. Women who have undergone bilateral(More)
