Two wireless ISNs are attached on arm and wrist for measuring rehabilitation exercise of frozen shoulder. The measured data are sent wirelessly to a base node where a Matlab-based program is developed for retrieving packet, parsing packets, and recognizing motion data based on the artificial neural network (ANN) algorithm. Six rehabilitation exercises for frozen shoulder are measured by wearing two nodes on the wrist and the arm. Accelerations in three axes and the derived angle form a 4-tuple vector as the motor feature of employed recognition algorithm. As results, five of six exercises are successfully recognized with 85-90 % of accuracy rates but the complex one (i.e. the spiral rotation exercise) reached only around 60 %. The pilot study approves good feasibility of self-developed WSN ISNs to recognize rehabilitation exercises as well as contribute advanced applications for mobile or ubiquitous health care in the future.","PeriodicalId":387991,"journal":{"name":"2013 7th International Symposium on Medical Information and Communication Technology (ISMICT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121249362","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 wireless body area network (WBAN) standard characterizes both medium access control and physical layer (PHY) specifications. The medium access is disregarded here and the focus is on PHY definitions. There are three different PHY options defined in the standard. The interest in this article is in impulse radio ultra wideband (UWB) definitions. In it, the on-off keying (OOK) modulation is stated to be the one used with the mandatory mode. The simulation model has been implemented according to the standard's UWB PHY definitions. The target in this study is to define (close to) an optimal integration interval for an energy detector receiver and an energy threshold required for the OOK detection. For the energy detector receivers, the optimal integration interval is channel dependent and playing an important role in the detection performance. As the data rate increases, the symbol duration is shortened in impulse radio UWB. Depending on the channel conditions, short symbols can be vulnerable for inter-symbol-interference. The used channel models in the simulations are the IEEE 802.15.6 channel model 3 (C M 3) and another one, measured in a real hospital environment at the Oulu University Hospital, Oulu, Finland. The study is continuing our earlier work related to the previously published impulse radio UWB standard, the IEEE 802.15.4-2011, earlier known as the IEEE 802.15.4a.","PeriodicalId":387991,"journal":{"name":"2013 7th International Symposium on Medical Information and Communication Technology (ISMICT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115473911","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}

One candidate to fulfill the reliably and efficiency requirements set by sending vital biomedical information is the novel IEEE 802.15.6 WBAN standard. In this paper, we study the effect of user priority scheme defined for different types of data in the IEEE 802.15.6 standard for medium access control (MAC) layer utilizing Slotted ALOHA channel access. A comparative performance analysis between the original IEEE 802.15.6-based communication system utilizing user priority scheme and a system utilizing a traditional random backoff scheme is presented in wireless hospital environment. Based on the results it can be stated that the performance of the IEEE 802.15.6 user priority scheme is approximately the same than the random backoff scheme in scenarios containing only high-priority medical data. However, in scenarios having both medical and low-priority nonmedical data transmissions the user priority scheme offers superior performance in terms of throughput and packet delivery ratio for medical applications.","PeriodicalId":387991,"journal":{"name":"2013 7th International Symposium on Medical Information and Communication Technology (ISMICT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133074997","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}
