Thirty-six participants who had chronic hemiparetic stroke, were recruited in this study, and were randomly distributed into three groups: TT with FES applied on the GM and TA muscles (Experimental group 1,12 patients), TT with FES applied on the TA muscle (Experimental group 2, 12 patients), and TT only (Control group, 12 patients). All participants were involved in a total of 20 sessions of TT with harness, 30 minutes per day, five times per a week for four weeks. They also received the regular physical therapy for 1 hour per day, five times per a week for four weeks. All participants were measured the digital muscle test, Berg balance scale (BBS), 6 minute walk test (6MWT), and spatiotemporal parameters before and after training. After training, Experimental group 1 showed significant improvement in hip abductor strength, BBS scores, 6MWT scores, gait velocity, and cadence compared to the Experimental group 2 and control group. These findings show that TT with FES applied on the GM and TA muscles contributed to producing increased lower extremity muscle strength, and improvements of balance and gait capacities. Therefore, it is suggestive that TT with FES applied on GM and TA can be beneficial intervention within the clinical settings in individuals with chronic hemiparetic stroke.","PeriodicalId":268238,"journal":{"name":"2014 IEEE 19th International Functional Electrical Stimulation Society Annual Conference (IFESS)","volume":"1 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":"128653013","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 aim of this study is to develop a rehabilitation system that delivers precisely controlled levels of stimulation to the shoulder, elbow and wrist during goal-oriented activity utilising everyday real objects. Iterative learning control (ILC) is used to update the stimulation signal applied to each muscle group based on the error between the ideal and actual movement in the previous attempt. The control system applies the minimum amount of stimulation required, maximising voluntary effort with a view to facilitating success at each given task. Markerless motion tracking is provided via a Microsoft Kinect, and a PrimeSense. Preliminary results show that ES mediated by ILC has successfully facilitated movement across the shoulder, elbow and wrist of chronic stroke patients. Overall, joint error has reduced for all participants with the mean error across all joints showing reductions for all participants. Furthermore, there was a significant reduction in extrinsic support necessary for each task. The system is described and initial intervention data are reported.","PeriodicalId":268238,"journal":{"name":"2014 IEEE 19th International Functional Electrical Stimulation Society Annual Conference (IFESS)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121079824","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}

This lack of movement may lead to further moral and physical complexities such as cardiovascular diseases, bone demineralization and bedsores. Physiotherapy based exercise and training are conventionally advised to such plegic patients, which, hereby, has not been shown to be have ample recovery efficiency. Alternatively, Functional electrical stimulation (FES) is a relatively newer technique which uses electrical signals to energize the neurons and excite the tissues in the muscles while producing the corresponding contraction in them. FES alone however requires specific electrical devices to generate and supply certain electrical signals similar to that of generated by human brain. This needs some additional devices to be used as the control system for FES to identify and issue the commands as required from time to time. A brain-computer interface (BCI) is a direct communication pathway between the brain and an external device. It uses electrodes, placed on the scalp, to collect signals from the brain structure. A combination of BCI and FES can be a vital solution to cater this issue, as the paralyzed patient can use his own brain electroencephalogram (EEG) as a control system to perform the required movements. This paper discusses their advantages, short comings and latest research advances in this field. Firstly, the significance of FES devices is being introduced and the different technological techniques reported in literature are discussed. Secondly, human brain is introduced as a control system to be employed within BCI systems to generate the required EEG signal activity. Finally, an incorporation of both FES and BCI is suggested to overcome the presiding issues regarding efficient control of the muscles.","PeriodicalId":268238,"journal":{"name":"2014 IEEE 19th International Functional Electrical Stimulation Society Annual Conference (IFESS)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133981009","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}

However, the extent of such intervention has not been weekly documented with regards to different stimulation frequencies. It is unknown whether high or low frequency (35 Hz or 20 Hz) has better potential in maintaining the FES effect in preventing SS during the follow-up period. Two participants underwent standard prescribed physiotherapy sessions in a rehabilitation centre during their hospitalisation period. Electrical stimulation was administered to their supraspinatus and posterior deltoid muscles for up to 2 hours a day for 4 weeks. All stimulation parameters were set constant except the stimulation current, which depended on the subject tolerance, and stimulation frequency, which was set to high (35Hz: Subject A) and low (20 Hz: Subject B). No SS among the intervened subjects during the 4 weeks FES therapy period. The high (35 Hz) stimulation frequency prevented subluxation until the end of 4 weeks follow up period in Subject A while low stimulation (20 Hz) frequency stimulation maintained the effect for up to 2 weeks in Subject B. The effect of FES on SS could be maintained up to 4 weeks upon withdrawal without undergoing subsequent FES therapy. Given all parameters fixed and the stimulation current dependent on the subject's tolerance, high frequency stimulation (35Hz) may be recommended in a subluxation prevention programs to further maintain the stability of the shoulder joint.","PeriodicalId":268238,"journal":{"name":"2014 IEEE 19th International Functional Electrical Stimulation Society Annual Conference (IFESS)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131520919","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}
