We describe procedures for repeated administration of inhibitors of muscarinic signaling to the levator auris longus (LAL) muscle of young adult mice and for subsequent immunostaining of its neuromuscular junctions (NMJs) in wholemounts. The LAL muscle has unique advantages for revealing in vivo pharmacological effects on NMJs.

The protocol described in this paper uses the mouse levator auris longus (LAL) muscle to record spontaneous and nerve-evoked postsynaptic potentials (current-clamp) and currents (voltage-clamp) at the neuromuscular junction. Use of this technique can provide key insights into mechanisms of synaptic transmission under normal and disease conditions.

Here we present a protocol to standardize the measurement of the levator ani hiatus size by magnetic resonance imaging. The purpose is to extract biomechanical inferences from image analysis by comparing resting and straining values in patients of both sexes with pelvic prolapse, using consistent anatomical bony landmarks.

Hip Exam

Source: Robert E. Sallis, MD. Kaiser Permanente, Fontana, California, USA The hip is a ball-and-socket joint that consists of the femoral head articulating with the acetabulum. When combined with the hip ligaments, the hip makes for a very strong and stable joint. But, despite this stability, the hip has considerable motion and is prone to degeneration with wear and tear over time and after injury. Hip pain can affect patients of all ages and can be associated with various intra- and...
FAQs
During difficult vaginal birth, fetal descent can place the levator ani under substantial stretching and compression. Marked distension may exceed the muscle’s capacity to maintain continuity, while instrumental delivery is identified as a circumstance associated with disruption. These forces help explain why childbirth history is important when clinicians investigate suspected pelvic-floor injury.
The pubic attachment is clinically important because disruption there can reduce the muscle’s contribution to pelvic-floor support. The resulting structural change does not by itself establish a specific symptom pattern, but it provides a possible anatomical explanation when pelvic organ prolapse or related dysfunction is being evaluated. Clinicians therefore interpret the finding alongside examination and imaging.
Recognizing the injury adds structural information to the assessment of pelvic organ prolapse and related dysfunction. It can help clinicians investigate whether reduced pelvic-floor support may be contributing to the patient’s presentation. The finding also supports more informed counseling about prognosis and helps determine whether follow-up or rehabilitation should be considered.
Assessment combines clinical examination with pelvic-floor imaging when appropriate. Clinicians may use translabial ultrasound or magnetic resonance imaging to evaluate the muscle and its attachment, while examination provides clinical context. Using these approaches helps identify the structural injury and relate it to concerns such as pelvic organ prolapse or other pelvic-floor dysfunction.
Translabial ultrasound and magnetic resonance imaging provide imaging options for assessing suspected Levator Ani Avulsion. They complement, rather than replace, clinical examination by allowing clinicians to investigate the muscle and its bony attachment. Their use can help clarify whether a structural injury is present when pelvic-floor support or related dysfunction requires further evaluation.
A confirmed or suspected injury can guide discussions about prognosis and the possible relationship between structural damage, reduced pelvic-floor support, and related dysfunction. Recognition also helps clinicians plan appropriate follow-up and consider rehabilitation. In this way, assessment supports ongoing management rather than serving only as a description of a childbirth-associated injury.
