RESUMO
BACKGROUND: Deterioration in upper extremity function has been a common problem among children with cerebral palsy (CP). The present study evaluated the effects of virtual reality (VR)-based rehabilitation combined with conventional occupational therapy (COT) on upper extremity function and caregiver assistance among children with CP. METHODS: Medical records of 17 children with CP who regularly participated in a rehabilitation program at Samsung Changwon Hospital were retrospectively reviewed. Ten children received VR-based rehabilitation, which utilized RAPAEL Smart Kids and video games combined with COT. Seven children received COT alone, which was provided by a trained occupational therapist and focused on their upper extremities. Clinical outcomes were determined using the Quality of Upper Extremity Skills Test (QUEST) and Pediatric Evaluation of Disability Inventory (PEDI), which were administered before and 8 weeks after the first intervention session. RESULTS: The smart glove (SG) group showed significant improvements in all QUEST domains and five PEDI domains (p < 0.05), whereas the COT group showed a significant change only in total QUEST scores. A comparison between both groups revealed that the SG group had significantly greater improvements in five QUEST domains and two PEDI domains (p < 0.05). CONCLUSIONS: Our results suggest that VR-based rehabilitation combined with COT may improve the upper extremity functions and decrease caregiver burden among children with CP.
RESUMO
In this randomized, double-blind, placebo controlled clinical trial, the effects of Dendropanax morbifera (D. morbifera) Léveille on heavy metal (cadmium and mercury) excretion as well as on lipid peroxidation and Cu, Zn-superoxide dismutase (SOD1) activity were investigated. For this study, tablets containing placebo or 300 mg of the leaf extract from D. morbifera Léveille were used. A total of 60 eligible healthy subjects were enrolled in this randomized, double-blind, placebo-controlled study. The differences in cadmium, mercury, and malondialdehyde (MDA) levels and SOD1 activity were measured in the serum 60 days after treatment with placebo or D. morbifera Léveille extracts. No significant differences between baseline characteristics and biochemical values were identified in subjects in the placebo and D. morbifera Léveille groups. Serum levels of cadmium, mercury and MDA decreased following consumption of D. morbifera Léveille extracts; however, no significant differences were identified. In addition, female, but not male, subjects who consumed D. morbifera Léveille extracts showed a significant increase in SOD1 activity. This result suggests that chronic consumption of D. morbifera Léveille extract can help to facilitate excretion of cadmium and mercury from serum and increase the antioxidant capacity in humans.
