This paper presents the implementation and evaluation of six trajectory-based metrics on the Virtual Peg Insertion Test, a technology-based assessment of upper limb function consisting of a goal-directed peg-in-hole task. A case study with four stroke patients illustrates the ability of the proposed metrics to describe motion patterns that differ from age-matched healthy subjects, and thus to objectively assess and track abnormal movement patterns.","PeriodicalId":241320,"journal":{"name":"International Convention on Rehabilitation Engineering & Assistive Technology","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121922319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the developing world motorbikes are often the only form of motorized transportation affordable to the majority of the population. Unfortunately this method of transportation has not been widely exploited anywhere in the world for use by people with severe mobility impairments, especially those who must use wheelchairs. To provide affordable transport for a wide range of mobility-impaired people I have developed an inexpensive sidecar adaptation for motorbikes, capable of transporting a wheelchair user (Figure 1). This adaptation is referred to as the SideScooter. The SideScooter can be operated independently with hand controls from the sidecar or from the motorbike seat, depending on the needs of the operator. Given the vast number of motorbikes in the world and the scarcity of independent transportation for wheelchair users this device has the potential to improve the quality of life for many disabled people in developing as well as the more affluent regions of the world.","PeriodicalId":241320,"journal":{"name":"International Convention on Rehabilitation Engineering & Assistive Technology","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127278169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The second dimension is to implement tools that enable hearing people to understand and learn sign language by converting natural language sentences into sign language.

However, widespread adoption by older adults of even the most affordable and simple systems has been mixed. While older adults may be the \"users\" of such technologies, we seek to understand the perceptions held by key \"influencers\" in the purchase and use decisions -- the adult child. We present an exploratory study based upon a convenience sample of adult children most likely to embrace intelligent home systems and services. Survey respondents are highly educated, technology savvy, middle to high-income adult children ages 35 and older. This group represents possible \"lead adopters\" who might advance the commercialization of these potentially useful technologies. Findings suggest that trust in the accuracy of the system, privacy concerns and willingness to intervene in a parent's home may present challenges to adoption even among tech-savvy adult children.","PeriodicalId":241320,"journal":{"name":"International Convention on Rehabilitation Engineering & Assistive Technology","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121729052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Behavioral data collected by the Haptic Knob were analyzed to evaluate motion control, smoothness and precision over the therapy. Subjects progressively improved their performances in the proposed functional exercises, suggesting improvement in hand motor function. This was confirmed by results of standard clinical assessment as subjects improved a mean of 4.3 points in the Fugl-Meyer assessment scale, accompanied by a decrease in spasticity.

Speech related potentials were visualized by grand averaging in the time domain. Feature data was obtained by filtering the time series data using optimal spatial filters designed through the common spatial patterns method. Resultant feature vectors were classified using a nonlinear support vector machine. Overall classification accuracies ranged from 68 to 78%.

For asynchronous BCI, the computer has to discriminate not only differences among various imaginary tasks but also detect relax periods. Since the training phase for building a classification model is still synchronous (cue-based), the main challenge is to classify the EEG signal continuously with good accuracy on asynchronous (uncue-based). This paper addresses achieving better performance by using a collection of overlapping sub windows models. A model is referred to a primitive classification model which consists of common spatial patterns (CSP) with linear discriminant analysis (LDA). Each primitive model was trained with the corresponding sub window indexes. We had 3 collections of models: task1 vs. task2, task1 vs. relax, and task2 vs. relax. These binary classification results were then fused together with Mahalanobis distance to gain better performance. The results were measured by mean square error (MSE), and their performance is better compared to the primitive model. Furthermore, the results on the test set were comparable to the 3 leading scores of BCI Competition IV dataset 1.","PeriodicalId":241320,"journal":{"name":"International Convention on Rehabilitation Engineering & Assistive Technology","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129806623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Physical practice of the affected limbs in the relatively early stages after stroke (i.e. acute and subacute stages) could achieve a more significant motor functional recovery than the post-stroke training introduced in the later stage (i.e. chronic stage); However, the recovering brain would face more risks of further damage in response to overexercise during the early stages than in the chronic period. In this study we have developed a platform to investigate fatigue change after stroke in rat. Results on 10 stroke rats showed decreases in mean power frequency (MPF) after the stroke surgery and larger co-contraction in the EMG signals, which were related to fatigue changes. The understanding on fatigue could help to generate suitable workload prescription for post-stroke rehabilitation, which will lead to an optimal functional and physiological recovery.","PeriodicalId":241320,"journal":{"name":"International Convention on Rehabilitation Engineering & Assistive Technology","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117053628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
