This study examined the effects of autistic behaviors and individual emotional and behavioral problems on parenting stress in caregivers of children with autism. Caregivers were interviewed with the Childhood Autism Rating Scale and completed the Strength and Difficulties Questionnaire and the Parenting Stress Index Short Form. Results revealed that caregivers of children with mild/moderate autistic behavior problems perceived lower parenting stress than did those of children with no or severe problems. In addition, prosocial behaviors and conduct problems respectively predicted stress in the parent-child relationship and child-related stress. The findings can provide guidance in evaluations and interventions with a focus on mitigating parenting stress in caregivers of children with autism.

The aim of this study was to discuss the influence of age, gender, obesity status, joint laxity, and the W-sitting habit on flatfoot in preschool-aged children. A total of 1,598 children (833 boys and 765 girls) between 3 and 6 years of age from kindergartens in the central area of Taiwan were studied. The children were divided into a normal group (n = 733), a unilateral flatfoot group (n = 266), and a bilateral flatfoot group (n = 599), and a multinomial logistic regression model was used to analyze the data. The prevalence of flatfoot decreased significantly with increasing age: 54.5% of 3-year-old but only 21% for 6-year-old children had bilateral flatfoot. In the bilateral flatfoot group, the risk decreased with increased age, increased with increasing weight beyond the normal range, and was higher for boys than girls. Age and obesity status were not significantly influential in the unilateral flatfoot group. Children with higher joint laxity and a habit of W-sitting also experienced higher risk in both flatfoot groups. In conclusion, this study demonstrates a significant association of age, gender, obesity status, joint laxity, and the W-sitting habit with the bilateral flatfoot in preschool-aged children. Children with unilateral flatfoot differ from those with normal feet and bilateral flatfoot. It is suggested that the unilateral flatfoot deserves special attention in future studies.

The 1-year follow-up found that some preschool-aged children with flatfoot may develop normal feet, while children with normal feet may begin to experience the signs. Relevant factors affecting flatfoot in preschool-aged children continue to require further clarification.

Background and Purpose. Global synkinesis (GS), or motor irradiation, is an involuntary movement associated with the coactivation of numerous muscles in one limb when the opposite limb is active. The electromyographic (EMG) patterns of people with stroke and people who were healthy were analyzed to characterize GS development in relation to joint involvement and to attempt to relate these findings to clinical observations. Subjects and Methods. Twenty patients with stroke, divided into 2 groups with either greater levels of irradiation (SG, n=10) or lesser levels of irradiation (SL, n=10), and 20 subjects in a control group were studied. A dynamometer was used to provide resistance for voluntary isometric muscle contractions of the flexor muscle groups of the shoulder, elbow, and wrist. The summated and standardized net EMG amplitudes of 8 principal muscles of the unexercised (paretic) upper extremity were used to characterize intensity and spatial representation of GS. Clinical measurements included the Fugl-Meyer Assessment Scale (FMA), Barthel Index of Activities of Daily Living (BI), and the stage on the Brunnström Stages of Motor Recovery Scale (BR). Results. In the SG and control groups, a more substantial GS intensity was associated with muscle contractions of the flexor muscles of the opposite proximal joint than was the case for contractions of the flexor muscles of the distal joint, whereas such a gradient change was absent in the SL group. The corresponding spatial patterns of GS exhibited a predominant cross-excitation over the unexercised pectoralis major and extensor carpi radialis muscles in the control group, contrary to the enhanced activation of the brachioradialis and biceps brachii muscles noted in patients with stroke. The SG group had a better FMA score and a more satisfactory BR stage than did the SL group, and the 2 neurological scores were related to GS intensity for patients with stroke, depending on joint involvement. Discussion and Conclusion. Intensity of GS provided an affiliation with motor deficits and a promising window for poststroke recovery mechanisms.
