In this study protocol, muscular force produced by quadriceps and the duration of achieving muscular fatigue would be compared between two different stimulation configurations of MEA. The first configuration uses an MEA to stimulate asynchronously 4 effective cathodes whereas the second configuration uses the MEA to stimulate 12 effective cathodes. Vibromyogram (VMG) sensors would be used for measuring force production and thus, detecting muscular fatigue. Pedal-based torque sensors would be used as well for obtaining the power output for both of the configurations. The objective of the study is to evaluate the effectiveness of increasing the number of effective electrodes in MEA for producing muscle force and delaying muscular fatigue.","PeriodicalId":268238,"journal":{"name":"2014 IEEE 19th International Functional Electrical Stimulation Society Annual Conference (IFESS)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126432630","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}

Most of the biomedical signals are non-linear, non-stationary, and non-Gaussian in nature. It is more useful to analyze them with HOS compared to the use of second-order statistics (power spectrum). There are some features in the bispectrum that are capable of differentiating between the signal and signal with noise. This study presents a technique of HOS to investigate the effect of noise on the features of third order statistics (bispectrum). The results show that the magnitudes of the bispectrum are consistently changing as a function of the amount of noise. In addition, these features can be extracted from the speech signal to compare with the respective behavioral responses, and thus a new metric to assess speech intelligibility and quality can be developed.","PeriodicalId":268238,"journal":{"name":"2014 IEEE 19th International Functional Electrical Stimulation Society Annual Conference (IFESS)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125101087","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}

A transverse intrafascicular multi-channel electrode (TIME) was developed for translational research to treat phantom limb pain (PLP). Four TIME systems (latest electrode version) have been implanted for 30 days into the arm of an amputee. After finishing successfully the clinical trials the TEVIE-3H systems have been explanted. The material composition of the electrode contacts used for stimulation have been investigated with X-ray photoelectron spectroscopy (XPS). System integrity has been examined using focused ion beam (FIB) and pictures were acquired using the integrated scanning electron microscope (SEM). Both methods revealed that the metallization was still intact after explantation and that no delamination occurred. Crack formation without delamination was observed but it could not be determined if it originated while the implant was inside the body or during the explantation or during the cleaning of the implants.","PeriodicalId":268238,"journal":{"name":"2014 IEEE 19th International Functional Electrical Stimulation Society Annual Conference (IFESS)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129785400","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}

A total of 30 subacute stroke patients were randomly allocated into one of the three groups: task-oriented EMG-triggered NMES group (El, n=10), task-oriented NMES group (E2, n=10), and control group (C, n=10). The patients in El group was trained with EMG-triggered NMES which was synchronized with a rehabilitative gaming system and two other tasks for 30 minutes a day, 5 times a week for 5 weeks, and E2 group was trained with NMES with the same tasks as El group for the same amount of time. Data collection included premotor reaction time (RT) of extensor carpi ulnaris (ECU) on EMG, Fugl-Meyer Assessment for the upper extremity (FMA), Motor Assessment Scale for the upper limb (MAS), and Box and Block test (B&B) before and after the intervention. El group showed a significant improvement in hand functions compared to E2 and the control group: premotor RT of ECU was significantly decreased, total scores of FMA and MAS were significantly increased, and number of blocks moved in B&B were significantly increased after the intervention (p<;.05). Present study demonstrated that task-oriented EMG-triggered NMES training in subacute stroke patients can effectively improve the paretic hand functions compared to task-oriented NMES training. Therefore, the use of task-oriented EMG-triggered NMES can be applied and included in the future rehabilitation program for the stroke patients who have restricted use of the hands. The findings in this study extend the evidence favoring both the motor and functional improvements for the paretic hand of subacute stroke patients.","PeriodicalId":268238,"journal":{"name":"2014 IEEE 19th International Functional Electrical Stimulation Society Annual Conference (IFESS)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124563556","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}

A novel manual controlled sliding stretcher FES rowing system has been recently developed, but it requires the rower with paralyzed lower limbs to maintain prolonged concentration and possess high finger dexterity to initiate leg neurostimulation. In contrast, an automatic controller for a fixed stretcher FES rowing system is able to stimulate legs over a longer stroke cycle compared to a manually controlled system. The present work describes the development of an automatic stimulation controller for a sliding stretcher FES rowing system with improved motion control by the rower during exercise by integrating a \"state-based rules\" derived from handle position.

In the second framework, for each electrode, an independent SMC was designed. The results of experiments on two rats show that a good tracking performance can be obtained using the proposed method.
