Aim: To characterize the motor repertoire of 3- to 5-month-old infants who were prenatally exposed to the infectious agents of syphilis and toxoplasmosis.
Methods: Exploratory observational study that evaluated 15 exposed infants (34.4 ± 3.5 weeks gestation) recruited from a referral center. Age assessment ranged 12-20 (median 12) weeks post-term. General Movement Assessment, including the Motor Optimality Score-Revised (MOS-R), was used to assess the global quality of fidgety movements (FMs) and to quantify and detail coexisting motor patterns. Clinical variables were also collected. Later motor outcomes were obtained from medical reports when possible.
Results: MOS-R ranged 10-26 (median 24). There was a higher proportion of infants with normal (80.0 %) than aberrant FMs, but the proportion of infants with reduced MOS-R (80.0 %) was higher compared to optimal MOS-R. One infant with aberrant FMs was later diagnosed with cerebral palsy. Only 13.3 % of the infants showed smooth and fluent movement character. All observed tongue movements were abnormal.
Conclusion: Infants had predominantly normal FMs, but with reduced MOS-R and abnormalities in the coexisting motor repertoire.

Early Motor Repertoire and Developmental Functioning at Later Age of Children Who Were Diagnosed with Autism Spectrum Disorder: A Pilot Study.

Faculty of Physical Therapy and Rehabilitation, Hacettepe University, Ankara, Türkiye.
Aims: Autism Spectrum Disorder (ASD) may exhibit early motor delay, and long-term motor impairments in addition to social and communicative problems. This pilot study aimed to describe (i) the early motor repertoire using General Movements Assessment (GMA) of infants later diagnosed with ASD, (ii) the developmental outcomes in these children between 24- and 42-months, and (iii) the relationship between GMA and developmental outcomes.
Methods: Ten children diagnosed with ASD were included.

A 40-year-old man presented to our hospital with subacute progressive muscle weakness in the limbs and leukocytosis. Subsequently, the patient was diagnosed with chronic lymphocytic leukemia (CLL) complicated by peripheral motor neuron neuropathy (axonopathy). Serology test for anti-ganglioside GM2 IgG antibody was positive, whereas paraneoplastic syndrome-related and anti-myelin-associated glycoprotein antibodies were not detected.

Background: The loss of finger control in individuals with neuromuscular disorders significantly impacts their quality of life. Electroencephalography (EEG)-based brain-computer interfaces that actuate neuroprostheses directly via decoded motor intentions can help restore lost finger mobility. However, the extent to which finger movements exhibit distinct and decodable EEG correlates remains unresolved.

Background: An age-related decline in motor flexibility, which is the ability to synergistically control the degrees of freedom of the body to ensure stable performance of a task, is a factor that contributes to falls. We investigated whether providing environmental constraints to increase the movement repertoire (i.e.

The vast majority of gene mutations and/or gene knockouts result in either no observable changes, or significant deficits in molecular, cellular, or organismal function. However, in a small number of cases, mutant animal models display enhancements in specific behaviors such as learning and memory. To date, most gene deletions shown to enhance cognitive ability generally affect a limited number of pathways such as NMDA receptor- and translation-dependent plasticity, or GABA receptor- and potassium channel-mediated inhibition.
