DOI: 10.1038/s41390-022-02222-5 PMID: 36042331

To investigate postnatal neural conduction in the auditory brainstem in neonatal bronchopulmonary dysplasia (BPD) survivors.... Thirty-two very preterm BPD survivors were studied at 57-58 weeks of postconceptional age. Brainstem auditory-evoked response was studied using maximum length sequence. Wave latencies and intervals we... Compared with normal term controls, BPD survivors showed significantly shortened I-III interval but significantly prolonged III-V interval and greater III-V/I-III interval ratio. Compared with very pr... Brainstem neural conduction in BPD survivors differed from normal term and age-matched non-BPD infants; neural maturation is accelerated in caudal brainstem regions but delayed in rostral regions. Neo... We found that brainstem neural conduction at PCA 57-58 weeks in neonatal BPD survivors differs from normal term and age-matched non-BPD infants. No major differences were found between normal term and...

The research was conducted to determine the effect of age on potential functional changes occurring through the transmission of nerve impulses in the motor nerves supplying selected muscles of the low... The study included a group of 54 men, differentiated by age. During the research, the speed of nerve conduction, amplitude and latency of the motor response in the tibial and peroneal nerves were meas... The results of the research showed that with age the ability to control muscle tone decreases, the speed of transmission of electrical impulses decreases, the motor response is delayed and its amplitu...

Detection of C8/T1 radiculopathy by measuring the root motor conduction time.

20 Oct 2022

DOI: 10.1186/s12883-022-02915-8 PMID: 36266617

Root motor conduction time (RMCT) can noninvasively evaluate the status of the proximal root segment. However, its clinical application remains limited, and wider studies regarding its use are scarce.... This was a retrospective cross-sectional study. Subjects were extracted from a general hospital's spine clinic database. A total of 48 C8/T1 root lesions from 37 patients were included, and 48 C8/T1 r... The RMCT of the C8/T1 radiculopathy group was 1.7 ± 0.6 ms, which was significantly longer than that in the control group (1.2 ± 0.8 ms; p = 0.001).
