There was no subspecialties differentiation such as physical therapy and occupational therapy of the rehabilitation therapy in most of institutions in China. The outstanding issues included teacher shortage, technological backwardness and imperfect practice education conditions of occupational therapy. The experience of cooperation was also introduced.

Patients often suffered limb dysfunction after stroke. Upper limb and hand function recovered more slowly than lower limb, and became one of the research focuses in rehabilitation medicine. Timely and effective assessments were important to guide the rehabilitation treatment, evaluate the treatment efficacy and predict functional recovery of upper extremity and hand function. The assessment methods of upper limb and hand motor function included subjective evaluations and objective evaluations. The former included different kinds of scales, which involved assessment focusing on muscle, motor pattern, change of upper limb and hand function. While the latter contained biomechanics, neuroelectrophysiology, functional magnetic resonance imaging, upper limb robotic evaluation system and so on. Scales were proved to have good reliability and validity. But they could not show patients' function accurately because of the subjectivity, and the data could not be kept. Evaluation system with computer was applied in clinical practice more and more widely. In this review, we summarized the assessments on upper limb and hand motor function in patients after stroke.

Executive impairment is one of the common sequelae of stroke, which seriously affects the quality of life of patients. Repeti-tive transcranial magnetic stimulation (rTMS), as a new type of electrophysiological technique, has been used in the clinical treatment of Post-Stroke Executive Impairment (PSEI). This paper summarized the survey of PSEI, the basic principle and mechanism of rTMS, clinical application of rTMS for PSEI and its safety. Clinical studies showed that high frequency stimulation, low frequency stimulation, and combi-nation with other therapeutic methods were effective in PSEI. However, there was no unified theory about the mechanism and the best treat-ment plan of rTMS for PSEI.

Objective To test reliability and validity of a verbal behavior assessment scale (VerBAS). Methods The VerBAS was used to evaluate 20 patients with speech disorder repeatedly by the same investigator with a two week interval to assess its reliability. The construct validity of the VerBAS was evaluated by using it to evaluate 235 patients with speech disorder. Results The test-retest correlation coefficient γ was 0.723,which was significant at the 5% confidence level. Cronbach'a a=0.819. Three distinct factors were identified: receptive speech,communicative speech and delineative speech;and their accumulated variance contribution was 83%. Conclusion The Verbal Behavior Assessment Scale had satisfactory reliability and validity, It can be used to evaluate the patients with speech disorder and could provide a reference for speech rehabilitation training.

Objective To observe the effect of virtual reality robotic hand on hand motor function and activities of daily living of pa-tients after stroke. Methods From June, 2015 to June, 2016, 32 patients with hand motor dysfunction were assigned into experimental group (n=16) and control group (n=16). The experimental group received training with virtual reality robotic hand and hand based rehabilitation, while the control group received hand based rehabilitation only, for four weeks. They were evaluated with Fugl-Meyer Assessment (FMA) of fingers and wrists and modified Barthel index (MBI) before and after treatment. Results The total score and the scores of items of FMA and MBI improved after treatment in the experimental group (Z>3.45 or t>3.45, P<0.01). The total score and the scores of the finger, wrist of FMA, and the scores of the eating, dressing and grooming of MBI improved in the control group (Z>2.07 or t>4.18, P<0.05). The total scores and scores of the items of FMA and MBI improved more in the experimental group than in the control group (Z>2.14 or t>3.20, P<0.05). Conclusion Virtual reality robotic hand training can promote the recovery of hand function and activities of daily living in patients af-ter stroke.

Functional magnetic resonance imaging (fMRI), a newly developing technique, contains function, anatomy and image, which makes the real-time, dynamic and non-invasive measurement of the functional brain imaging availability. This paper summarized the characteristics of fMRI in health and stroke populations, introduced the advances of fMRI in neuroplasticity, rehabilitation assessment and prognosis in hand movement dysfunction in patients with stroke, and discussed the difficulty fMRI faced in rehabilitation assessment and the further researches.

BACKGROUND:Our previous studies confirmed that NGF-PEG-PLGA-NPs has good sustained release effect and biological activity in vitro, and can induce the differentiation of PC12 cel s into neuron-like cel s.
OBJECTIVE:To investigate the feasibility of neuronal differentiation of neural stem cel s from septal area of fetal brain induced by NGF-PEG-PLGA-NPs and its influence on PI3K/Akt signaling pathway.
METHODS:According to optimization prescription, NGF-PEG-PLGA-NPs were prepared by multiple emulsion solvent diffusion method. Neural stem cel s were induced to neuronal differentiation in six groups, including control group, NGF group, NGF-PEG-PLGA-NPs group, LY294002 group, LY294002+NGF group and LY294002+NGF-PEG-PLGA-NPs group. Neurons were identified by immunofluorescence, while phosphorylation levels of Akt in PI3K/Akt signaling pathway were detected by western blotting.
RESULTS AND CONCLUSION:The proportions ofβ-Tubulin III-positive neurons in control group, NGF group, NGF-PEG-PLGA-NPs group, LY294002 group, LY294002+NGF group and LY294002+NGF-PEG-PLGA-NPs group were (22.80±2.58)%, (35.80±3.98)%, (35.40±5.77)%, (26.60±3.87)%, (21.20±2.59)%and (25.80±7.22)%, respectively. There were no statistical differences in neuronal differentiation between NGF group and NGF-PEG-PLGA-NPs group (P>0.05), but the ratios of neural differentiation in the two groups were both higher than that in the other four groups (P<0.05). Western blotting results revealed that there were no statistical differences in Akt phosphorylation levels between NGF group and NGF-PEG-PLGA-NPs group (P>0.05), but the phosphorylation levels of Akt were both higher than other four groups (P<0.05). There were also no significant differences between LY294002+NGF and LY294002+NGF-PEG-PLGA-NPs groups and control group (P>0.05), but the phosphorylation levels of Akt were higher than LY294002 group (P<0.05). Results suggest that NGF-PEG-PLGA-NPs promoted neural differentiation of neural stem cel s. The role might be related to increasing phosphorylation levels of Akt in PI3K/Akt signaling pathway.
