The Role of Age and Initial Deformation on Final Cranial Asymmetry in Infants with Plagiocephaly Treated with Helmet Therapy.

Background/aims: To characterize the impact of cranial asymmetry and age at initiation of therapy on final cranial asymmetry in infants with deformational plagiocephaly treated with helmet orthotics.

Methods: We conducted a single-center retrospective review of 45 pediatric patients <12 months of age with deformational plagiocephaly who underwent STARband cranial orthotic helmet treatment. Cranial asymmetry was measured using a 3-dimensional laser surface scanner and defined as a cranial vault asymmetry index (CVAI) >3.

Reliability Assessment of Various Sonographic Techniques for Evaluating Carpal Tunnel Syndrome.

Objectives-The aim of this study was to determine the intra- and inter-rater reliability of sonographic measurements of the median nerve cross-sectional area in individuals with carpal tunnel syndrome and healthy control participants.Methods-The median nerve cross-sectional area was evaluated by sonography in 18 participants with carpal tunnel syndrome (18 upper extremities) and 9 control participants (18 upper extremities) at 2 visits 1 week apart. Two examiners, both blinded to the presence or absence of carpal tunnel syndrome, captured independent sonograms of the median nerve at the levels of the carpal tunnel inlet, pronator quadratus, and mid-forearm.

Electrodiagnosis in neuromuscular disease.

Electromyography (EMG) is an important diagnostic tool for the assessment of individuals with various neuromuscular diseases. It should be an extension of a thorough history and physical examination. Some prototypical characteristics and findings of EMG and nerve conduction studies are discussed; however, a more thorough discussion can be found in the textbooks and resources sited in the article.
