Subjects with CD and healthy controls completed an online survey using WHIGET tremor rating scale. One thousand five hundred and twelve subjects completed the survey, finally 674 CD patients and 290 healthy subjects were included. A higher prevalence of tremor in CD patients was observed in comparison to controls(28% vs 14%, P < 0.001). Frequency of family history of tremor in CD patients with and without tremor was 25% and 20%(P = 0.2), while in the control group it was 41% and 10%(P < 0.001). Controls with tremor showed a higher frequency of family history of tremor when compared to CD patients with tremor(41.5% vs 24.6%, P = 0.03). The results suggested that tremor in CD might be more frequent and possibly related to the disease itself and not due to associated essential tremor.展开更多

Methods: A total of 60 ischemic stroke cases were randomly allocated into an observation group and a control group, 30 in each group. Other than basic and conventional rehabilitation therapies, cases in the observation group were treated with reinforcing and reducing manipulation on yin and yang meridians points for a period of 8 weeks; whereas cases in the control group only received the same basic and conventional rehabilitation therapy as that in the observation group. Then the knee joint energy, support moment and shaking moment were compared between the two groups before treatment, and after 4-week and 8-week treatment respectively. Results: Before treatment, there were no between-group significant differences in knee joint energy, support moment and shaking moment(all P>0.05). After treatment, the knee joint energy, support moment and shaking moment in both groups were significantly improved(P<0.05). After 8 weeks of treatment, the knee joint energy, support moment and shaking moment in both groups were significantly improved than that of 4-week treatment(P < 0.05). In addition, there were between-group statistical significances in comparing knee joint energy, support moment and shaking moment after 4 and 8 weeks of treatment(P<0.05). Conclusion: Reinforcing and reducing manipulation by breathing on yin and yang meridian points can increase the knee joint support and shaking force and moment in stroke patients and improve their walking ability.展开更多
