Depression and anxiety are common in amyotrophic lateral sclerosis (ALS) patients and caregivers. ⋯ Depression and anxiety in ALS patients and their caregivers were associated closely with each other but not with physical disability or disease duration in our Chinese population.

During lumbar flexion, the fiber orientation of the lumbar erector spinae (LES) muscle becomes oriented more along the spine compressive axis. It is unknown how changes in LES activation effect fiber orientation. ⋯ Activation magnitude and spine posture both affect LES fiber orientation, thus modifying its ability to protect the spine against anterior shear forces.

Multifocal pyomyositis is a rare inflammatory myopathy caused by bacterial infection and abscess formation in multiple skeletal muscles. To date, electromyography (EMG) of pyomyositis has not been reported. ⋯ Muscles affected by pyomyositis demonstrate EMG features similar to those of other inflammatory myopathies. Other features such as acute entrapment neuropathy may exist concomitantly due to nerve compression from muscle abscess formation.

In this study we aimed to determine whether high-resolution ultrasound (US) can identify the iliohypogastric (IH), ilioinguinal (II), and genitofemoral (GF) nerves and their relations. ⋯ High-resolution ultrasound (US) can identify the IH, II, and GF nerves at the level of the abdominal wall and the terminal branches in the majority of volunteers.

In this exploratory study we investigated whether ultrasound can visualize the neonatal cervical roots and brachial plexus. ⋯ Ultrasound of the neonatal cervical nerve roots is feasible and may be used as a non-invasive screening technique to assess nerve root integrity in obstetric brachial plexus injury.
