Background and Purpose: Lower limb spasticity is often a significant problem in stoke rehabilitation. The purpose of this study was to investigate the effects of acupuncture treatment on lower limb spasticity in patients following hemorrhagic stroke. Methods: Fifty-nine patients following hemorrhagic stroke were randomized to receive acupuncture treatment combined with conventional treatment (treatment group [TG]) or conventional treatment only (control group [CG]). Acupuncture treatments were given in 24 sessions over 4 weeks. Blinded evaluation was based on Modified Ashworth Scale (MAS), short intracortical inhibition (SICI), and Hmax/Mmax ratio as the primary outcomes. In addition, Fugl-Meyer Assessment (FMA), Barthel Index (BI), motor evoked potential (MEP) and surface integrated electromyogram (IEMG) were employed as the secondary outcomes. All the evaluations were performed at 14 and 28 days after the start of the treatment. Results: Compared with the CG, the TG showed a significantly greater over-time decrease in MAS for knee (p = 0.022) and ankle (p = 0.017), SICI (p = 0.000) and Hmax/Mmax ratio (p = 0.000). In all patients of TG, we found a greater improvement in lower-limb FMA and MEP but not in BI. IEMG show that TG obtained a greater reduction in spastic agonist muscles and a greater enhancement in spastic antagonist muscles. A significant correlation between a greater decrease in ankle MAS and a greater increase in SICI for spastic muscles was found (r = 0.390, p = 0.002). Conclusions: Acupuncture could improve the lower limb spasticity and motor function, thus providing a safe and economical approach for treating stroke patients. The potential mechanism underpinning the greater improvement may be attributed to a reshape of corticospinal plasticity induced by acupuncture.

Dyskinetic cerebral palsy (CP) is the second major subtype of CP. Dyskinetic CP can be classified into different subtypes, but the exact clinical characteristics of these subtypes have been poorly studied. To investigate the clinical characteristics and functional classification of dyskinetic CP from the perspective of neurologic subtypes in a hospital-based follow-up study.This was an observational study of consecutive children with dyskinetic CP treated at The Affiliated Women & Children Hospital of Qingdao University (China) from October 2005 to February 2015. The children were stratified according to their neurologic subtype and assessed with the Gross Motor Function Classification System (GMFCS), Manual Ability Classification System (MACS), and Communication Function Classification System (CFCS). MRI scanning was conducted at 1 year of age for most children.Twenty-six participants (28.0%) had dystonic CP, 26 (28.0%) had choreoathetotic CP, and 41 (44.1%) had mixed CP. Auditory impairment and basal ganglion lesions occurred more frequently in the dystonia group (n = 8, 31%; and n = 16, 67%), while seizures, microcephaly, white matter lesions, and mixed lesions were more frequent in the mixed type (n = 14, 34%; n = 10, 24%; n = 15, 41%; n = 12, 32%). Functional classification levels were distributed unequally among the 3 subgroups (P < .01). No significant difference between GMFCS and MACS was found among the 3 subgroups (P > .05).Different subtypes of dyskinetic CP have specific comorbidities, radiological characteristics, and functional attributes according to their etiological factors and brain lesions. Children with dystonic CP have more limited functional status than children with choreoathetotic CP.

Cohen syndrome is a rare, genetic, connective-tissue disorder, which is caused by mutations in the gene COH1 (VPS13B, Vacuolar Protein Sorting 13 Homolog B) at the chromosome 8q22. The disease is rare reported, which major clinical features include postnatal microcephaly, obesity, short stature, intellectual disability, progressive retinal dystrophy, intermittent neutropenia and many other unusual facial feature. We report four patients in China who were diagnosed with Cohen syndrome by genetic testing and clinical manifestations. At the same time, we review the related literature, and further expound the molecular mechanism of the disease, a variety of clinical manifestations, treatment and prognosis.
