On admission to CRI, patients have the option to sign a UCLA-approved consent to be contacted about research projects that might be applicable to them in the coming 1-2 years. Potential participants who have signed this will be contacted by a study investigator or the coordinator who is listed as trained to do so. Dr. Dorsch, who routinely attends on the stroke rehabilitation unit at CRI, will also approach potential subjects on his service if they seem appropriate for the trial. In addition, a flyer (submitted) will be provided to patients with stroke during their inpatient rehabilitation stay who may be interested in the study, but are not patients of Dr. Dorsch. They can contact the study coordinator if interested in participation. Some patients may not decide about participation until after inpatient discharge. They will be further screened after signing a consent by Drs. Dobkin or Dorsch or a neurologist serving as a rehabilitation fellow who has been added to the IRB consent process. Potential participants will be shown how their practice will be monitored with sensors, if they wish.
