ABSTRACT
Breast cancer survivors often suffer from a variety of complications post operation, such as upper limb dysfunction, limb lymphedema, brachial plexus nerve injury, and so on. This article reviewed the pathogenesis and rehabilitation of these complications.
ABSTRACT
Objective To investigate the effect of transcranial direct current stimulation (tDCS) on aphasia recovery after stroke. Meth-ods From April, 2012 to January, 2013, 20 aphasic patients after stroke were enrolled in an A-B experiment design. During phase A, ten times of sham tDCS and language training (five days a week) were implemented, then ten times language training combined with tDCS (five days a week) were implemented in phase B. The treatment lasted for four weeks. Picture naming was measured for all patients before and af-ter treatment both in phase A and phase B. Results The D-value scores of picture naming before and after treatment were significantly more in phase B than in phase A in both treatment items and non-treatment items (t>3.030, P<0.05). Conclusion tDCS could raise the accuracy of picture naming in patients with aphasia after stroke.
ABSTRACT
@#Objective To investigate the effects of transcranial direct current stimulation (tDCS) on motor function of upper limbs of stroke patients. Methods 80 stroke patients were randomly divided into experimental group and control group. Both groups accepted routine rehabilitation, while the experimental group accepted anodal stimulation, and the control group received sham stimulation. They were assessed with Brunnstrom stages of arms and hands, Fugl-Meyer Assessment (FMA) of upper extremities, Action Research Arm Test (ARAT), Motor Assessment Scale (MAS) and modified Barthel Index (MBI) before and 1 month after treatment. Results All the scores improved in both groups after treatment (P<0.05), and improved more in the Brunnstrom stages of arms and hands, FMA, ARAT in the experimental group than in the control group (P<0.05). Conclusion tDCS may promote the recovery of arms and hands function of stroke patients.
ABSTRACT
@# ObjectiveTo observe the effects of different environmental intervention on neurofilament (NF) expression in rats after unilateral local cerebral infarction. MethodsAfter middle cerebral artery occluded (MCAO) by electric coagulation, 125 male SD rats were randomly divided into individual living group (n=30, living alone in small standard cages), social communication group (n=30, 5 as a group living in large standard stages ), learning group(n=30, 15 as a group living in exploratory cages), enriched environment group (n=30, 5 as a group living in EE cages) and sham operated group(n=5). The rats were randomly sacrificed at the 1st, 3rd, 7th, 14th, 21st, 28th day after MCAO. The expressions of NF in peri-ischemic cortex were detected with immunohistochemistry staining. ResultsThe expression of NF in the peri-ischemia cortex in enriched environment group and learning group was higher than that in other two groups (P<0.01) after 7 days, it also was higher in social communication group than that in individual living group (P<0.05). ConclusionEnriched environment and learning could enhance NF expression in rats after unilateral local cerebral infarction.
ABSTRACT
@#Objective To study the effect of exploratory environment on behavioral recovery and the expression of neurogranin (Ng) in rats after unilateral local cerebral infarction. Methods 70 male Sprague-Dawley rats were adopted. After making the model of MCAO with electric coagulation, 60 rats were randomly divided into exploratory group (n=30, living in maze cages) and control group (n=30, living in large standard cages). Other 10 rats as the sham group lived in standard cage. 10 rats were chosen randomly from the groups for Berderson test, manual muscle and balancing test on the 1st, 7th, 14th, 28th day after operation, and 5 rats were sacrificed separately in exploratory group and control group at the same time. 5 rats in sham group were randomly sacrificed separately on the 7th, 28th day after operation. The expressions of Ng in the peri-ischemic cortex were detected with immunohistochemistry stain. Results The scores of behavior in exploratory group improved compared with that in control group (P<0.05) from 14 d after operation. The number of Ng positive cells increased in exploratory group compared with that in control group (P<0.01) from 7 d after operation. Conclusion Exploratory environment can facilitate the functional recovery and the Ng expression in rats after unilateral local cerebral infarction.
ABSTRACT
@#Objective To study the effect of motor imagery on balance rehabilitation in hemiplegics after stroke.Methods 20 hemiplegic patients who were in chronic stage(above 6 months)were randomly divided into two groups.Normal rehabilitation was performed in the whole stage and motor imagery was added in group A in stage Ⅰ and group B in stage Ⅱ.All patients were assessed with Berg Balance Scale(BBS),blance subscale of the Fugl-Meyer Assessment(FM-B),max affected limb-loading per weight and Functional Independence Measure(FIM)at the beginning and the ending of the every stage,respectively.Results The deference scores of BBS and FIM,as well as max affected limb-loading per weight between in the stage with motor imagery was better than those in the stage without motor imagery(P<0.01),as well as that of FM-B score(P<0.05).Conclusion Motor imagery can improve balance rehabilitation and activity of daily living in chronic hemiplegics.
ABSTRACT
@#ObjectiveTo study the effect of exercise on expression of p38 after cerebral infarction in rats.MethodsThe right middle cerebral artery was occluded(MCAO) with electric coagulation in Wistar rats,and then were divided into three groups at random 48 hours later: training group which were given wheel-running exercise everyday(n=20);control group(n=20) and sham group(n=10).The expression of p38 in cortex of the three groups were detected on 7th,14th,21th and 28th day after the MCAO.ResultsIn the cortex around the infarcted focus,the expressions of p38 elevated much significantly after cerebral infarction(P<0.05).The expression of p38 in training group were higher than those in control group(P<0.05) on the 21th and 28th day.ConclusionThe cerebral infarction could induce the expression of p38.The exercise could enhance its expression.
