The gait of seven hypotonic schizophrenic children aged between five and eight years was compared with that of seven normal children aged between seven and eight years. Electromyographic studies revealed that in schizophrenic children the tibialis anterior was 'on' during a significantly smaller proportion of the stance phase than in the age-matched controls, and that the quadriceps muscle was 'on' during a significantly smaller proportion of the swing phase than in the controls. In addition, the gait of the schizophrenic children tended to be broad-based and slow, consisting of smaller steps in a longer pace period. In general, the gait of the schizophrenic children resembled that of younger, inexperienced walkers.
The aim of the study was to compare a variety of surface EMG (sEMG) parameters in several groups of schizophrenia (SZ, n=69) patients and healthy controls (n=44). We computed spectral, mutual information (MI) based and recurrence quantification analysis (RQA) parameters of sEMG. The major finding is that sEMG of the controls had higher values of the MI-based parameter, mean and median spectrum frequencies, and lower values of most of RQA parameters. It means higher content of recurrent fragments in sEMG of SZ patients. We suggest that the differences might be caused by either denervation/renervation process of single muscle fibers in SZ patients and/or by increased motor unit synchronization induced by antipsychotic therapy.
Blunt trauma abdomen rarely leads to gastrointestinal injury in children and isolated gastric rupture is even rarer presentation. We are reporting a case of isolated gastric rupture after fall from height in a three year old male child.
