Is Handheld Lower-Resolution Ultrasound Evaluation Sufficient to Measure the Cross-Sectional Area of the Median Nerve?

Purpose: This study aimed to assess the accuracy of median nerve cross-sectional area (CSA) measurements using a handheld ultrasound (HHUS) and a cart-based high-resolution ultrasound.

Methods: Fifteen healthy subjects were prospectively enrolled. Each subject underwent standardized ultrasound evaluations of their median nerves with HHUS and a high-resolution ultrasound by three different providers with different levels of training in musculoskeletal ultrasound.

Ultrasound verification of palpation-based dry needling techniques of rotator cuff muscles: a prospective feasibility trial.

Objectives: The primary purpose of this study is to investigate the feasibility of using ultrasound to verify the placement of narrow-gauge dry needles within the supraspinatus and infraspinatus muscles utilizing palpation-based dry needle techniques.

Methods: This is a prospective observational study with 10 participants recruited. Each participant had a dry needle placed within the infraspinatus and supraspinatus muscles by a trained physical therapist utilizing palpation-based methods.

Femoral and Lumbar Fractures During Rehabilitation for a Traumatic Spinal Cord Injury in Osteogenesis Imperfecta: A Case Presentation.

Unlabelled: Osteogenesis imperfecta (OI) is one of the most common inherited bone disorders. These individuals are high-risk for developing fractures during their lifetime secondary to bone fragility. This case presents a female with type I OI involved in a high speed motor vehicle accident resulting in a traumatic spinal cord injury (SCI) and paraplegia.

Capabilities of neurexins in the chick ciliary ganglion.

Transcellular interactions between neuroligins (NL) and beta-neurexin have been widely documented to promote maturation and function of both glutamatergic and GABAergic synapses. Recently it has been shown that neuroligin-1 plays a similar role at nicotinic synapses on chick ciliary ganglion neurons in culture, acting from the postsynaptic side to enhance transmitter release from adjacent cholinergic terminals and boost nicotinic input to the cells. We show here that the ciliary ganglion expresses three forms of neuroligin as well as two beta-neurexins and an alpha-neurexin.
