본 연구는 만성 뇌졸중 환자를 대상으로 과제 지향적 훈련을 기반으로 하는 자조활동 프로그램이 상지 운동기능 및 자기효능감에 미치는 영향을 알아보고자 하였다. 지역사회에 거주하는 만성 뇌졸중 환자 20명을 대상으로 연구를 진행하였다. 자조활동 훈련 프로그램은 상지 과제 지향적 훈련으로 총 6주간, 주 4회 40분의 프로그램으로 구성하였으며, 매주 1회 집단훈련을 통해 훈련 프로그램을 점검하였다. 상지 운동기능의 변화를 알아보기 위해 맨손기능 검사, 악력 검사를 실시하였으며, 자기효능감 변화를 알아보기 위해 자기효능감 척도를 이용하여 설문 조사를 실시하였다. 상지 운동기능 검사 결과, 자조활동 훈련 전에 비해 자조활동 훈련 후 맨손기능과 악력이 모두 증가되었으며, 통계적으로 유의한 차이를 나타내었다(p<.05). 자기효능감 변화를 관찰한 결과, 자조활동 훈련 전에 비해 자조활동 훈련 후 자기효능감이 향상되었으며, 통계적으로 유의한 차이를 나타내었다(p<.05). 이상의 결과를 종합해 볼 때 과제 지향적 훈련을 기반으로 하는 자조활동 훈련 프로그램이 만성 뇌졸중 환자의 상지 운동기능 향상에 효과적이며, 과제 성취감을 경험하게 함으로써 신체의 운동기능 회복뿐만 아니라 자기효능감에도 긍정적인 영향을 미친 것을 알 수 있었다.

본 연구는 아급성뇌졸중환자의 상지기능과 일상생활수행능력에 대한 상상훈련의 효과를 알아보기 위해 시행되었다. 연구대상자들은 총 16 명으로 상상훈련군과 대조군에 8 명씩 무작위로 할당되었다. 상상훈련군은 4주 동안 주 5회, 매일 30의 상상훈련과 30분의 과제지향훈련을 시행하였고 대조군은 4주 동안 주 5회, 매일 30분간 과제지향훈련을 시행하였다. 측정은 상지기능의 변화를 알아보기 위해 울프운동 기능검사(Wolf motor function test, WMFT)와 Fugl-meyer 운동기능평가(Fugl-Meyer motor function assessment, FMA)를 측정하였고, 일상생활수행능력의 변화를 알아보기 위해 수정된 바델 지수(modified Barthel index, MBI)를 사용하여 측정하였다. 본 연구의 결과는 상상훈련이 대조군에 비해 모든 검사에서 더 유의한 향상을 보였다(p<.05). 그리고 훈련 전후의 효과크기는 상상훈련을 시행하였을 때 WMFT와 FMA는 각각 1.59, 2.02로 큰 효과를 나타냈으며, MBI는 0.37로 최소의 효과를 나타났다. 이러한 결과는 상상훈련이 상지기능과 일상생활수행능력 향상에 도움이 될 수 있으며, 상상훈련의 임상적용 가능성을 지지한다.

Background: For performing various movements well, cooperation between the muscles around the scapula and shoulder has been emphasized. Taping has been widely used clinically as a helpful adjunct to other physiotherapy methods for shoulder pathology and dysfunction treatment. Previous studies have evaluated the effect of taping techniques using dynamic tapes on shoulder function and pain. However, no study investigated the electromyographic (EMG) changes in the shoulder muscles. Objects: This study aimed to investigate the effect of the upper limb offload taping technique using a dynamic tape on EMG activities of the upper trapezius (UT), lower trapezius, serratus anterior (SA), and middle deltoid (MD) muscles during scaption plane elevation. Methods: A total of 26 healthy subjects (19.85 ± 6.40 years, male = 20) volunteered to participate in this study. The subjects were instructed to perform scaption elevation with and without dynamic taping on the shoulder. Shoulder elevation strength tests were performed at 100%, 75%, 50%, and 25%, for the maximal isometric contraction force. Results: There were statistically significant interaction effects between the taping application and shoulder scaption elevation force in EMG activities in the UT (p < 0.05) and MD (p < 0.05). EMG activities in the UT showed significant increases in 50%RVC (reference voluntary contraction, p < 0.05) and 25%RVC (p < 0.01). Furthermore, the EMG activity of the SA significantly increased in 50%RVC (p < 0.01) and 25%RVC (p < 0.01) after dynamic taping. For the MD, the EMG activity level significantly decreased in 100%RVC (p < 0.05). Conclusion: These results indicated that upper limb offload dynamic taping application affects the muscle activities of some shoulder muscles depending on different scaption elevation strength levels. Therefore, we suggest that the upper limb offload dynamic taping can be applied to the shoulders when patients need middle deltoid inhibition or upper trapezius facilitation, such as patients with shoulder impingement syndrome.

The need for human body posture robots has led researchers to develop dexterous design of exoskeleton robots. Quantitative techniques to assess human motor function and generate commands for robots were required to be developed. In this paper, we present a passivity based adaptive control algorithm for upper limb assist exoskeleton. The proposed algorithm can adapt to different subject parameters and provide efficient response against the biomechanical variations caused by subject variations. Furthermore, we have employed the Particle Swarm Optimization technique to tune the controller gains. Efficacy of the proposed algorithm method is experimentally demonstrated using a seven degree of freedom upper limb assist exoskeleton robot. The proposed algorithm was found to estimate the desired motion and assist accordingly. This algorithm in conjunction with an upper limb assist exoskeleton robot may be very useful for elderly people to perform daily tasks.

We developed a symmetrical upper limb motion trainer for chronic hemiparetic subjects. This trainer enabled the practice of a forearm pronatio $n^ination and wrist flexion/extension. In this study, we have used functional magnetic resonance imaging(fMRI) with the developed symmetrical upper limb motion device, to compare brain activation patterns elicited by flexion/extension wrist movements of control and hemiparetic subject group. In control group, contralateral somatosensory cortex(SMC) and bilateral cerebellum were activated by dominant hand movement(Task 1), while bilateral movements by dominant hand(Task 2) activated the SMC in both cerebral hemispheres and ipsilateral cerebellum. However, in hemiparetic subject group, contralateral supplymentary motor area(SMA) was activated by unaffected hand movement(Task 1), while the activation of bilateral movements by unaffected hand(Task 2) showed only SMA in the undamaged hemisphere. This study, demonstrating the ability to accurately measure activation in both sensory and motor cortex, is currently being extended to patients in clinical applications such as the recovery of motor function after stroke.ke.

In order to fully utilize the functions of the hand which is the end effector of the upper limb, other parts of the upper limb have to perform their own roles. Among them, the pronation and supination of the forearm, which allows the hand to rotate along the longitudinal direction of the forearm, play an important role in activities of daily living. In this paper, a soft wearable robot that assists the pronation and supination of the forearm for individuals with weakened or lost upper limb function is proposed. The wearable robot consists of an anchoring part with polymer (wrist strap, elbow strap), a tendon with a belt and wire, and an actuation module. It was developed based on the requirements with respect to friction of anchoring part, forearm compression, and friction of the tendon. It was confirmed that these requirements were satisfied through literature review and experiments. Since all components exist within the forearm when worn, it is expected to be easy to combine with the already developed soft wearable robots for the hand, wrist, elbow, and shoulder.

Objective: Electrical stimulation is an assistive technology used to aid the recovery of upper limb use after stroke. The purpose of this systematic review was to determine the effects of electrical stimulation on upper extremity function in individuals with hemiparetic stroke and to develop an evidence base that supports the use of electrical stimulation for upper limb recovery after stroke. Design: A systematic review based on randomized controlled trials (RCTs). Methods: Studies published before April 20 2021 were collected for this review by searching PubMed, four other databases, and RCTs that reported the effects of electrical stimulation on upper extremity function in individuals with the characteristic stroke type. Information on the following parameters was extracted from each study: surname of first author, published year, country, participants, intervention, intervention's intensity, comparison, outcomes, additional therapy, and summary of results. This review also evaluated the bias within each study, including any selection bias, performance bias, detection bias, attrition bias, and reporting bias. Results: This review included five RCTs, and 208 stroke patients were included in the analysis. Stroke patients who underwent electrical stimulation showed significantly improved grip and pinch strengths, wrist range of motion, and basic daily living compared to those in the control group; however, there was no improvement in upper extremity function. Of the selected papers, 60% showed a "high risk" of performance bias, and 20% showed a "high risk" of detection bias. Conclusions: The results of this systematic review suggest that electrical stimulation provides some benefits to stroke patients, such as improved hand strength and range of motion. However, future studies are needed to provide clinical evidence of the effects of electrical stimulation on upper extremity function in stroke patients.

뇌졸중 후 편마비(Hemiplegic) 환자들의 상지기능 저하는 손을 많이 쓰는 일상생활 수행에 있어서 신체적 동작뿐만 아니라 심리적인 불편함이 매우 크다. 본 논문에서는 편마비 환자들의 상지기능 개선을 위하여 자체 제작한 상지 재활 보조장치를 이용하였다. 이 장치는 팔이 움직일 수 있는 관절가동범위(Range Of Motion)와 손의 악력 크기를 사용하여 훈련 콘텐츠를 수행할 수 있다. 이 장치를 이용한 훈련 콘텐츠는 환자의 흥미와 능동적인 참여를 유도하기 위해 VR(Virtual Reality)로 구현되었으며, 환자 혼자서 훈련하는 심리적 부담을 덜어주기 위해 멀티플레이 환경으로 구성하여 환자의 재활훈련에 간병인이 함께 참여할 수 있도록 하였다. 본 연구에서 제작된 장치와 훈련 콘텐츠를 사용하여 손의 악력 크기와 팔의 관절가동범위의 변화를 정량적으로 측정하고 시각적으로 보여줌으로써 환자나 간병인이 쉽게 상지기능 개선정도를 확인할 수 있는 장점이 있다.
