The primary goal of this study is to report on the safety of the study device when used at home. In addition, the study will report on observed changes in upper extremity function and strength after a period of home use.~The LIFT Home Study will enroll subjects who have recently completed participation in the Up-LIFT Study. The study includes a set of baseline assessments to be completed in the clinic, a four-week home use treatment program prescribed by the investigator, and a final set of clinic-based assessments at the end of the study.~At the baseline visit, the subject and caregiver will be trained on the use of the device and prescribed a specific training regime for its use at home. The subject will be issued a device that is uniquely programmed to operate within a limited set of parameters as specified by the investigator.~Throughout the study, subjects will be prompted to report all adverse events (AE) regardless of relatedness to the device.~At baseline and the final clinic visit, UE strength and function will be measured with stimulation off using a comprehensive set of assessment tools including CUE-T, GRASSP, Pinch and Grasp Force, as well as patient and caregiver global impression of change questionnaires.
The LIFT Home Study is an observational, single-arm study designed to assess the safety of non-invasive electrical spinal stimulation (ARC Therapy) administered by the LIFT System to treat upper extremity functional deficits in people with chronic tetraplegia.
