Carpal tunnel syndrome (CTS) is a common peripheral neuropathy, which include a series of symptoms results from median nerve injury. Electrical physical examination is the gold standard for diagnosis of CTS. More new technology, such as high frequency ultrasound and magnetic resonance imaging, provides more information for the diagnosis of CTS.

Objective To analyze the activities of daily living (ADL) performance in children with cerebral palsy (CP) with different gross motor function and the correlation between gross motor function and ADL perform-ance. Methods A total of 118 children (81 boys and 37 girls; mean age: 47.7 months, SD: 20.1 months, age range: 18-90 months) with CP were recruited from three different rehabilitation centers in Shanghai. Types of CP included hemiplegia (n = 27), spastic diplegia (n = 53), spastic quadriplegia(n = 29), athetoid (n = 4), dystonic (n = 4), ataxic (n = 1). Gross motor function classification system (GMFCS) and Gross motor function measure (GMFM) were adopted to assess and classify the gross motor function. Pediatric evaluation of disability inventory (PEDI) was adopted to assess ADL performance. Differences of PEDI scores were compared among different levels of GMFCS; and the correlation between GMFCS levels, GMFM scores and PEDI scores were analyzed. Resnlts PEDI scores showed significant differences among CP children with different levels of GMFCS. The PEDI score usually de-creased with the increase of the GMFCS level, and mobility ability was the lowest. Significant correlations were found between PEDI scaled scores and GMFCS (rs = 0.85～0. 50, P < 0.001). Various levels of correlations (r = 0. 85～ 0.54, P<0.001) were found between GMFM scores and PEDI scaled scores. Higher correlations were found between GMFCS levels, GMFM scores and mobility ability. Conclusion ADL performance was significantly different among CP children with different gross motor function. The higher the gross motor function, the better the performance of ADL. Mobility would be improved by promoting gross motor function in CP children. The training of self-care and so-cial communication ability should be emphasized.

Objective To compare the effect of motor development massage and neural development approach on the children with cerebral palsy. Methods The children with cerebral palsy were selected with layered matching as they accepted motor development massage or neural development approach, and reviewed with their score of Gross Motor Function Measure (GMFM-66). Results There were 24 children in each group. The GMFM-66 score increased after treatment in both groups, but there was no statistical difference between these groups. Conclusion The gross motor function can be improved in the children with cerebral palsy with motor-development massage and neural development approach similarly.

Objective To observe the effect of rehabilitation training on fine motor in children with Down syndrome. Methods 30 children with Down syndrome accepted rehabilitation training for 3.1~4.6 months. They were assessed with fine motor function in Peabody Developmental Motor Scales (PDMS-FM) before and after treatment. Results The scores of fine motor quotients, grasping and visual-motor integration improved after treatment(P<0.05). Conclusion Rehabilitation can improve the fine motor in children with Down syndrome.

Objective To work out the Cerebral Palsy-Gross Motor Function Questionnaire(CP-GMFQ) and evaluate the reliability,validity and responsiveness of CP-GMFQ.Methods 160 children with cerebral palsy(CP)(97 males and 63 females;average age: 47.7±20.1 months,range: 18～90 months) were involved.The first 27 children received second assessment to assess test-retest reliability with a interval of 7 to 18 days.Criterion-related validity was evaluated by comparing CP-GMFQ scores with Gross Motor Function Classification System(GMFCS) levels and scores of Gross Motor Function Measure(GMFM).21 children were randomly selected for responsiveness analysis by effect size.After a interval of 3 to 7 months the re-assessment GMFQ and GMFM were tested.30 children were randomly selected for comparative testing time of GMFQ and GMFM.Results GMFQ had excellent test-retest reliability(ICC=0.9940);criterion-related validity was excellent between GMFQ scores and GMFCS levels and GMFM scores(r=0.77～0.92).Effect size of GMFQ(0.34) between GMFM88 and GMFM66,testing time of GMFQ(average 4.7±1.6 min) were significantly less than testing time of GMFM(average 17.7±4.6 min)(P<0.001).Conclusion The reliability,validity and responsiveness of GMFQ are satisfying.The gross motor functions of children with cerebral palsy could be easy and reasonably measured by GMFQ.

AIM:To explore the influence of long-term swimming on peripheral neuropathy in type 2 diabetic rats.METHODS:Male Wistar rats were fed with a high-fat and high-fructose diet, and injected with streptozocin to estab-lish a model of type 2 diabetes mellitus.The rats were randomly divided into 4 groups:blank control group (C group), ex-ercise control group ( CE group ) , diabetes mellitus group ( DM group ) and diabetes mellitus +exercise group ( DME group).The rats in CE group and DME group received 8-week swimming training (6 d/week).The training time was 20, 30 and 45 min in the first 3 d,respectively, and then it increased to 60 min a day.Eight weeks later, the motor nerve conduc-tion velocity ( MNCV ) and the levels of tumor necrosis factor α( TNF-α) , interleukin 6 ( IL-6 ) and C-reactive protein ( CRP) in sciatic nerve tissues of the rats were measured .The morphological changes of the sciatic nerve were also observed under light microscope .RESULTS:Compared with DM group , 8-week swimming obviously accelerated the MNCV ( P<0.05), decreased the levels of TNF-α, IL-6 and CRP in DME group (but no significant difference, P>0.05).The obvi-ous nerve injury in DM group was observed .However , the pathological change of the sciatic nerve in DME group was re-lieved.CONCLUSION:Eight-week swimming training significantly accelerates the MNCV , attenuates the nerve injury in diabetic rats and has protective effect on peripheral nerve , which may be correlated with relieving the inflammatory reaction .

Objective To determine the reliability of hand-held electronic dynamometer (HHD) tests for lower limb muscle strength measurement in children with spastic cerebral palsy (CP). Methods Twenty-eight children ( 15 boys and 13 girls; mean age 5 years 8 months) with different types of CP (2 with spastic quadriplegia,8 spastic diplegia, 6 hemiplegia, 1 triplegia and 1 monoplegia) , and at different functional levels ( 19 graded at gross motor function classification system level Ⅰ, 6 level Ⅱ, 2 level Ⅲ and 1 level Ⅳ ) were recruited from the Rehabilitation Center of the Children's Hospital of Fudan University. Standardized HHD protocols were used to measure the strength of their hip, knee and ankle muscles. The HHD test was performed by the same examiner twice with an interval of 10 min in between. The HDD test was also performed with 15 randomly selected CP children by 2 examiners with an interval of 10 min in between. The test-retest and inter-rater reliabilities of the HDD readings were determined by calculating the intra- and inter-class correlation coefficients. Results The HHD measurements showed fine testretest reliability ( ICC = 0.74-0.97 ) and inter-rater reliability ( ICC = 0.63-0.97 ) in measuring lower-limb muscle strength of children with spastic CP, with the highest test-retest reliability for the hip flexion, foot plantar flexion and knee extension muscle groups. The highest inter-rater reliability was achieved with the hip flexion and foot dorsiflexion muscle groups. Conclusions Standardized HHD testing of lower-limb muscle strength in children with spastic CP shows fine test-retest and inter-rater reliability. The HHD can reliably assess the lower-limb muscle strength of children with spastic CP.

Objective To study the application value of electroencephalogram and CT in children with cerebral palsy.Methods Electroencephalogram and CT examinations were carried out in 224 children with cerebral palsy.Results Abnormal prevalence of electroencephalogram was 47.77%, 58.88% of which were found as epileptic discharge. Abnormal prevalence of CT was 79.46%. The abnormal rate of CT was significantly higher than that of electroencephalogram ( P<0.001). The abnormal rates of electroencephalogram and CT among different types of cerebral palsy were not significantly different ( P>0.05).Conclusion Combination of CT and electroencephalogram will be helpful for the diagnosis and treatment in children with cerebral palsy.

ObjectiveTo explore the reliability of Modified Ashworth Scales(MAS) measuring muscular tone of lower extremities of children with spastic cerebral palsy(CP).Methods31 children with spastic CP(19 males, 12 females) were included in this study. The mean age for the children was （51.3±26.8） months; 20 diplegia, 7 quadriplegia, 4 hemiplegia. The muscle tone of hip adductor, hamstring, soleus muscles were tested bilaterally with MAS in lower extremity of the children. Two evaluators used the MAS to assesse the muscles tone of children. To compare with the relativity of the results of interrater and intrarater, the reliability was confirmed.ResultsThe reliability of interrater was poor, the total ICC value was 0.68, while better for the reliability of intrarater, the total ICC value was 0.83.ConclusionIt should be cautions in assessment of spasticity of muscles in the lower extremities of children with spastic CP by MAS.
