Objective:To investigate the effects of mirror neuron theory-based visual feedback therapy(VFT)on restoration of upper limb function of stroke patients and motor-related cortical function using functional magnetic resonance imaging(fMRI).Methods:Hemiplegic stroke patients were randomly divided into two groups:a VFT group and a control(CTL)group.Sixteen patients in the VFT group received conventional rehabilitation(CR)and VFT for 8 weeks,while 15 patients in the CTL group received only CR.The Barthel Index(BI)was used to assess the activities of daily living at baseline and the 8th week of the recovery training period.The Fugl-Meyer assessment(FMA)scale,somatosensory evoked potential(SEP),and fMRI were used to evaluate the recovery effect of the training therapies.The latencies and amplitudes of N9 and N20 were measured.Before recovery training,fMRI was performed for all patients in the VFT and CTL groups.In addition,17 patients(9 in the VFT group and 8 in the CTL group)underwent fMRI for follow-up 2 months after treatment.Qualitative data were analyzed using the x2 test.The independent sample t-test was used to compare normally distributed data among different groups,the paired sample t-test was used to compare data between groups,and the non-parametric test was used to comparing data without normal distribution among groups.Results:There were no significant differences between the VFT and CTL group in all indexes.However,after 8 weeks of recovery training,these indexes were all significantly improved(P<0.05).As compared with the CTL group,the FMA scores,BI,and N9/N20 latencies and amplitudes of SEP in the VFT group were significantly improved(P<0.05).Two months after recovery training,fMRI showed that the degree of activation of the bilateral central anterior gyrus.parietal lobe,and auxiliary motor areas was significantly higher in the VFT group than the CTL group(P<0.05).Conclusions:VFT based on mirror neuron theory is an effective approach to improve upper extremity motor function and daily activity performance of stroke patients.The therapeutic mechanism promotes motor relearning by activating the mirror neuron system and motor cortex.SEP amplitudes increased only for patients who participated in visual feedback.VFT promotes sensory-motor plasticity and behavioral changes in both the motor and sensory domains. 展开更多

BACKGROUND Supernumerary phantom limb(SPL)caused by spinal cord injury(SCI)has previously been reported in several studies.However,the mechanisms and management of SPL in SCI patients are still not fully understood.Herein,we report a rare case of SPL in a patient with incomplete SCI.CASE SUMMARY A 46-year-old man complained of four hands 7 d after SCI.He was diagnosed with SPL complicated with actual limb neuropathic pain.Following a period of treatment with neurotrophic agents and Chinese traditional and analgesic medications,SPL symptoms and actual limb pain did not improve.However,his symptoms gradually lessened after combined treatment with high-frequency repetitive transcranial magnetic stimulation(rTMS),a promising neuromodulation technique,over the M1 cortex and visual feedback.After 7 wk of this treatment,SPL disappeared completely and actual limb pain was significantly relieved.CONCLUSION Cerebral plasticity changes may be a mechanism underlying the occurrence of non-painful SPL in SCI patients,and high-frequency rTMS applied to the M1 cortex could be a promising treatment method for SPL. 展开更多

To measure the latency between human motion stimulation and stereo image display response in a visual feedback-based minimally invasive surgical(MIS) robotic system,a method was proposed by comparing the orientations of input and output events through image-processing technology. This method used a black bar to keep pace with the measured joint rotating at a number of speeds. During tests,an external camera was placed in front of the apparatus with a proper visual field,so that it can simultaneously view orientations of both bars fixed on the corresponding joints. After quantitatively analyzing the accuracy of the proposed measurement method,the method was applied to a visual feedback-based master–slave robotic system with two-degrees-of-freedom. Experimental results show that the latency of the overall system was approximately 250 ms,and the opposite clearance of the measured joint was in the range of 1.7°–1.9°. 展开更多

Object recognition, which consists of classification and detection, has two important attributes for robustness: 1) closeness: detection windows should be as close to object locations as possible, and 2) adaptiveness: object matching should be adaptive to object variations within an object class. It is difficult to satisfy both attributes using traditional methods which consider classification and detection separately; thus recent studies propose to combine them based on confidence contextualization and foreground modeling. However, these combinations neglect feature saliency and object structure, and biological evidence suggests that the feature saliency and object structure can be important in guiding the recognition from low level to high level. In fact, object recognition originates in the mechanism of "what" and "where" pathways in human visual systems. More importantly, these pathways have feedback to each other and exchange useful information, which may improve closeness and adaptiveness. Inspired by the visual feedback, we propose a robust object recognition framework by designing a computational visual feedback model (VFM) between classification and detection. In the "what" feedback, the feature saliency from classification is exploited to rectify detection windows for better closeness; while in the "where" feedback, object parts from detection are used to match object structure for better adaptiveness. Experimental results show that the "what" and "where" feedback is effective to improve closeness and adaptiveness for object recognition, and encouraging improvements are obtained on the challenging PASCAL VOC 2007 dataset. 展开更多

This paper investigates the visual servoing robust stabilization of nonholonomic mobile robots. The calibration of visual parameters is not only complicated, but also needs great consumption of calculated time so that the accurate calibration is impossible in some situations for high requirement of real timing. Hence, it is interesting and important to consider the design of stabilizing controllers for nonholonomic kinematic systems with uncalibrated visual parameters. A novel uncertain model of these nonholonomic kinematic systems is proposed. Based on this model, a stabilizing controller is discussed by using dynamic feedback and two-step techniques. The proposed robust controller makes the mobile robot image pose and the orientation converge to the desired configuration despite the lack of depth information and the lack of precise visual parameters. The stability of the closed loop system is rigorously proved. The simulation is given to show the effectiveness of the presented controllers. 展开更多

目的探讨视反馈步态分析训练对急性脑梗死后偏瘫患者肢体功能恢复的康复效果。方法纳入2021年5月-2023年5月河南科技大学第一附属医院收治的急性脑梗死后偏瘫患者86例,根据随机数字表法分为观察组和对照组,各43例。两组均给予常规康复训... 目的探讨视反馈步态分析训练对急性脑梗死后偏瘫患者肢体功能恢复的康复效果。方法纳入2021年5月-2023年5月河南科技大学第一附属医院收治的急性脑梗死后偏瘫患者86例,根据随机数字表法分为观察组和对照组,各43例。两组均给予常规康复训练,观察组同时给予视反馈步态分析训练,均8周。比较两组干预前后运动功能、平衡能力、姿势控制能力、起立-行走测试时间、步态参数。结果干预后,两组Fugl-Meyer下肢肢体运动功能评分(FMA)、5次坐立测试(FTSST)、起立-行走测试时间(TUGT)及步行周期、步长偏差、患健侧支撑比值、患健侧摆动比值均降低,且观察组评分低于对照组(P<0.05);干预后,两组Berg平衡评分(BBS)、步速、步频均升高,且观察组评分高于对照组(P<0.05)。结论视反馈步态分析训练可促进急性脑梗死后偏瘫患者运动功能恢复,增强平衡功能、坐-站转移能力,改善偏瘫导致的步态异常。 展开更多
