The purpose of this study is to examine effects of constraint-induced movement therapy(CIMT) and/or cognitive-perceptual training(CPT) on the change of hand function in cerebrovascular accident(CVA) patients and to evaluate the change in the amount and quality of use of the affected upper extremity in performing daily living tasks. The subjects of study were 10 patients who had been under rehabilitation for more than three months after CVA onset. They were all determined as mild cognition impairment according to NCSE or MVPT test. For CIMT group, to restrict the movement of the unaffected hand the subjects had been worn modified resting arm-splint in daytime for 4 weeks. For CIMT+CPT group, the subjects were performed CPT with CIMT and control group had been under conventional occupational therapy for the same period. CIMT+CPT group showed significant improvement in simulated feeding, lifting large light objects, and lifting large heavy objects of Jebsen-Taylor Hand Function Test. CIMT group also showed significant improvement compared with control group. The mean changes of the amount of use(AOU) of the affected arm had a statistically significant difference among groups (p<.05). While CIMT+CPT group had the biggest change in the quality of movement(QOM) of upper extremity of the affected side, CTL group showed the smallest change. Both CIMT and CIMT+CPT groups had statistically significant difference in the change in the quality of movement in upper extremity of affected side with CTL group(p<.05), but there was not significant difference between CIMT group and CIMT+CPT group. CIMT performed to the patients of stroke, with mild impairment in cognitive perceptual abilities showed the improvement in hand movement and AOU and QOM of upper extremity in the affected side and the combination of CIMT with CPT showed synergic effects.

The purpose of this study was to investigate the effect of the home-based virtual reality (VR) on upper extremity motor function in hemiparetic stroke patients. Two matched subjects with left hemiplegia were volunteered to participate in this study. One subject received the home-based VR whereas the other subject recovered a modified home-based constraint-induced movement therapy (CIMT). Both interventions were given for 4 hours x 5 times a week for 4 weeks. Outcome measures included Fugl-Meyer Assessment (FMA), Motor Activity Log (MAL), and Wolf Motor Function Test (WMFT). The VR-trained subject showed considerable improvement in all the tested motor functions when compared with the home-based CIMT. Specifically, the FMA measure demonstrated that the VR subject showed 17% enhancement whereas the CIMT subject showed 5% increase. Similarly, Amount of Use (AOU) and Quality of Movement (QOM) of the MAL scores of the VR subject showed 40% and 20% increase whereas the CIMT subject showed 0% and 20% increase, respectively. The WMFT scores of the VR subject and CIMT subject showed 20% increase. Our home-based VR was effective in upper extremity motor recovery of chronic hemiparetic patients even when compared with the well-established CIMT approach in stroke victims.

The purpose of this study was to investigate the convergence effect of focal vibration stimulation and bilateral upper limb training on the recovery of upper limb function when applied to stroke patients. For 20 stroke patients, divided into an experimental group that performed convergence intervention with focal vibration stimulation and bilateral upper limb training, and a control group who performed only bilateral upper limb training. It was conducted 20 times for 4 weeks, 30 minutes per session. Vibration stimulation was applied to the affected side of the experimental group for 30 minutes during training. Results were measured for the degree of recovery of the affected upper limb function, amount of use on the affected and unaffected sides, the quality and satisfaction in performance on use of both upper limbs. Comparisons were made within groups using a paired-sample t-test and between groups using covariance analysis. As a result of the study, the experimental group showed a significant difference in dexterity and the amount of use on the affected than the control group. The effect size was more than the small effect size in all evaluation items. Through this study, it is thought that the convergence intervention of focal vibration stimulation and bilateral upper limb trainingcan be used clinically as an effective intervention for the recovery of arm function in stroke patients.

This paper aims at the development and clinical evaluation of the wireless gyro-mouse system. The wireless gyro-mouse system is a computer interface with gyro-sensor and wireless communication, for the patients with upper-extremity disabled from the traffic accident or stroke to use the computer software i.e. internet browser. In the development, we focused on, firstly, to make the system wireless for the patients to manipulate the mouse easily even on the bed or wheelchair, secondly, to insert the gyro-sensor into a headband for easy don-and-doff and aesthetic appearance, thirdly, to devise a click switch in case of $C5{\sim}C6$ patients and a head nodding detection in case of C4 patients for sending click message to computer operating system. We performed evaluation experiment for patients with upper-extremities disabled from spinal cord injury. The results show that the displacement error of the cursor position against the target position during linear (vertical/horizontal) movement manipulation decreased with trial number. The click rate per minute also increased with trial number. This indicates the developed wireless gyro-mouse system would be more useful to the patients with repetitive use.

Background and Purpose : Paresthesia is a common symptom in stroke patients, but very little research has been done on that. The purpose of this research was differentiating the syndromes of paresthesia in stroke patients. Methods: We studied about the paresthesia in 21 stroke patients. To differentiate the syndromes of paresthesia in stroke patients, we use oriental medicine methods. The locations of the lesions were identified with the use of CT and/or MRI. Results: The differentiation of syndroms about paresthesia were Yinhuyanghangzeng, Hynleozeng and Hwaynlzeng in order of frequency. Yinhuyanghangzeng was more frequent in female and at upper extremity. Hyuleozeng was accompanied with Qihuzeng and Yinhuyanghangzeng and its duration of disease was relatively long. Hwayulzeng was more frequent in male and its duration of disease was short. Conclusions : We hope there are more studies about the differentiation of syndroms and exantinations of paresthesia in many stroke patients.
