Objective To explore the effect of robot-assisted gait training on pelvis kinematics and the walking function of hemiplegic stroke survivors.Methods Thirty stroke survivors with hemiplegia were randomly divided into a treatment group and a control group,each of 15.Both groups were given routine clinical medication and rehabilitation training,while the treatment group was additionally provided with 20 minutes of robot-assisted gait training a day,6 d/wk for 8 weeks.Before and after the treatment,all of the patients' pelvis kinematics were assessed using 10 m walking speed (MWS),the timed up and go test (TUGT) and functional ambulation categorization (FAC).Results Before the treatment there were no significant differences between the two group in any of the measurements.After the treatment,significant improvement was observed in both groups in the vertical displacement and rotation and tilt angles of the pelvis while walking,with significantly more improvement in the treatment group than in the control group.There was also significant improvement in the average walking speed,TUGT time and FAC score of both groups,with significantly more improvement in the treatment group.Conclusion Robot-assisted gait training can significantly improve the pelvis control and walking ability of hemiplegic stroke survivors.

Objective To explore the the characteristics of non-motor symptoms of essential tremor(ET).Methods Totally 50 ET patients and 45 age-gender-matched healthy volunteers,admitted in Department of Neurology,The Second Affiliated Hospital of Zhejiang University School of Medicine from May 2015 to April 2016,were included.Clinical data and tremor analyses under different postures were obtained.The non-motor symptoms were evaluated using the Pittsburgh Sleep Quality Index(PSQI),Hamilton anxiety scale(HAMA),Hamilton's Depression Scale(HAMD),and the MOS item short from health survey (SF-36).Cognitive functions were evaluated by the Minimental state examination(MMSE).Results ET group had lower MMSE total score of (25.81 ±2.75 vs.28.16 ± 1.71),increased rate of dyssomnia (62.0％ vs.15.6％) and higher PQSI score (6.42±2.71 vs.3.84±2.13)compared with the control group(all P＜0.05).Moreover,more patients in the ET group had moderate and severe anxiety(60.0 ％ vs.37.8 ％),moderate and severe depression (34.0％ vs.15.6％)than the control group(both P ＜ 0.05).Anxiety and depression had effects on physical and mental health and were also related to the quality of life.Conclusions Non-motor symptoms,such as mild cognitive deficits,depression,anxiety and dyssomnia are common in ET patients.Furthermore,depression and anxiety have negative effects on physical and mental health.

Objective To investigate the changes in cognitive function in patients with early Parkinson's disease (PD) in a 5-year follow-up.Methods A total of 181 PD and 173 normal participants were recruited between January 2009 and January 2012 at the Department of Neurology,the Second Hospital of Jiaxing City.Regression analysis was used to evaluate the risk factors of cognitive impairment,and changes in subdomains of the Montreal Cognitive Assessment (MoCA) were compared annually with baseline data.Results Baseline clinical data were similar between the two groups.The level of cognitive impairment was positively correlated to the age of onset and the Hamilton Anxiety Scale (H AMD) (t =3.326,P＜ 0.05;t =5.211,P＜0.01),and negatively correlated to education level (t=-2.505,P＜0.05).There were no statistical differences in the first (26.5 ± 2.6),second (26.3±3.2) and third year (25.9±2.9) in the total scores of MoCA,which significantly increased in the forth (24.4 ± 2.3,P＜0.05) and fifth (24.1 ± 1.2,P＜0.05) year compared with baseline levels (26.7±2.9).However,in the control group,differences between any two years in total scores were not statistically significant (all P＞0.05).Seven subdomains of MoCA were attenuated,and four of them were significant different between the groups,including delayed recall,attention,abstraction task and orientation after the forth year of follow-up (all P ＜ 0.05).Meanwhile,visuospatial execution capacity was attenuated before the third year,and then rose markedly (P＜0.05).In the control group,the between-year differences of seven subdomains were not statistically significant (all P＞0.05).Conclusions Cognitive function of PD patients decreases significantly in some domains,such as delayed recall,attention,abstraction task and orientation after a five-year followup.

Objective To explore the effect of occupational therapy on the cognitive function and P300 event-related potentials (ERPs) of patients with acute cerebral infraction.Methods Ninety-eight acute cerebral infarction patients with cognitive impairment were selected using the mini-mental state examination (MMSE).They were randomly divided into an observation group (n =49) who received occupational therapy plus routine rehabilitation treatment and a control group (n =49) who received only the routine rehabilitation treatment.Before and after 8 weeks of treatment,the patients' cognitive function and their ability in the activities of daily living(ADL) were evaluated using the Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) and the modified Barthel index (MBI),respectively.P300 ERPs were also detected.Results There was no significant difference between the two groups with regard to various scores before the treatment (P ＞ 0.05).After 8 weeks of treatment,the LOTCA and MBI scores and the latency and amplitude of ERPs were significantly better than those before treatment in both groups (P ＜ 0.05).In the observation group,the scores of LOTCA (99.4 ± 8.4),MBI (80.7 ± 5.9) and the latency and amplitude of ERPs [(373.45 ± 52.13) ms and (5.87 ± 2.63) μV,respectively] were significantly better than those in the control group(P ＜ 0.05).Conclusion Occupational therapy program based on conventional rehabilitation training can promote the ADL ability and cognitive function of patients with acute cerebral infraction.It is worth applying in clinical practice.
Résumé
Objective To explore the effects of leukoaraiosis on cognitive function in elderly patients after acute cerebral infarction.Methods From May 2010 to August 2011,a total of 147 elderly patients with acute cerebral infarction were enrolled,including 96 patients with leukoaraiosis and 51 patients without leukoaraiosis.The Montreal Cognitive Assessment (MOCA) and the correlative factors of cognitive function were assessed in all patients.Results There was no statistical difference in general information between patients with and without leukoaraiosis.There were significant differences in the MoCA scores between patients with and without leukoaraiosis (x2 =19.15,P＜0.01),as well as between the vital and non-vital positions of cerebral infarction (x2=21.41,P＜0.01).The Logistic regression analysis showed that the vital position of infarction and leukoaraiosis were related to the cognitive impairment (OR=12.27,6.60,both P＜0.01),while the area of infarction and the type of cerebral infarction in Oxford County Community Stroke Project (OCSP) had no effects on cognitive impairment.Pearson correlation analysis showed that there was a positive relationship between the degree of white matter lesions and the decline in cognitive function (r=-0.87,P＜0.01).Conclusions The position of acute cerebral infarction and leukoaraiosis are independent risk factors for cognitive function after acute cerebral infarction,and the former plays a more important role than does the latter.
