To develop a non-invasive treatment technique for patients with upper limb treatment-resistant tremor, we have designed a wireless wearable stimulation system that utilizes tremor movement using a three-axis accelerometer to modulate tremor movement with a real-time closed-loop algorithm. We analyze tremor movements by changing the stimulation parameters (i.e., amplitude, frequency, duty cycle, phase, stimulation sites, and time spacing between the pulse trains) to find an open-loop response for the tremor movement by various stimulation parameters. The real-time tremor analysis provides the phase information of each tremor cycle, and we investigate the effects of phase-locked stimulation using an accelerometer and electromyography.\u0026nbsp;The standardized tasks based on the Fitts\u0027 law have been used for assessing the performance of arm movement with tremor by controlling a three-dimensional gyration mouse on a computer. The quantitative tremor assessment method can be used for the evaluation of the efficacy of electrical stimulation for patients with upper limb tremor. The real-time closed-loop tremor mouldation system determines the most effective stimulation parameter sets, and we evaluate the system using a quantitative assessment that verifies the efficacy of stimulation.\u0026nbsp;\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Real-time Closed-loop Tremor Modulation using Peripheral-nerve Stimulation"}],"uid":"28475","created_gmt":"2016-07-29 16:55:11","changed_gmt":"2016-10-08 02:18:33","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2016-08-10T12:00:00-04:00","event_time_end":"2016-08-10T12:00:00-04:00","event_time_end_last":"2016-08-10T12:00:00-04:00","gmt_time_start":"2016-08-10 16:00:00","gmt_time_end":"2016-08-10 16:00:00","gmt_time_end_last":"2016-08-10 16:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"434371","name":"ECE Ph.D. Proposal Oral Exams"}],"categories":[],"keywords":[{"id":"1808","name":"graduate students"},{"id":"102851","name":"Phd proposal"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
