|Spinal Cord Injuries||Device: User-controlled FES system||Not Applicable|
Battelle has developed a novel wearable sleeve that can reanimate a paralyzed limb via Functional Electrical Stimulation (FES) that is controlled non-invasively by the user. Previous work has shown the ability of this sleeve and FES technology to significantly enhance independence and quality of life when controlled by an implanted brain-computer interface, thus now investigators plan to trial use of the high-definition FES system with simpler, non-invasive control mechanisms to expedite translation of this technology into real-world settings. Each participant will complete up to 10 research sessions (~1.5hrs each) in their residence or at an alternative location. The study location is restricted to Columbus Ohio and surrounding areas. Participants will be compensated for their time.
In Aim 1, investigators will evaluate the ability of a non-invasive, user-controlled FES system to increase functional hand use in the homes of individuals with SCI. The research team will train participants to use the FES system for different functional hand movements and activities they identify as important to them, then measure FES system effectiveness using standardized assessments.
In Aim 2, investigators will assess the viability of using the sleeve technology to non-invasively record muscle activity as the participant attempts different functional movements.
In Aim 3, human-centric design methodology and contextual inquiry interviews will be employed to understand study participants' needs and preferences for a FES assistive device. This information will determine actions to improve usability and optimize the system for unsupervised home use.

- Feasibility of FES sleeve as a functional orthosis for activities of daily living [ Time Frame: 10 weeks ]Semi structured interviews will involve gaining participants opinions on the strengths and weaknesses of the system
- Quadriplegia Index of Function (QIF) [ Time Frame: At study completion, 10 weeks ]Self-report tool assessing 37 activities of daily living with each task scored from 0 to 4 in order of increasing independence.
- System Usability Scale (SUS) [ Time Frame: At study completion, 10 weeks ]Questionnaire composed of 10 statements that are scored on a 5-point scale of strength agreement from strongly disagree to strongly agree. The questionnaire is designed to assess the overall usability of a system or product.
- Change in Graded Redefined Assessment of Strength, Sensibility, and Prehension (GRASSP) after 10 weeks [ Time Frame: 10 weeks ]Standardized test will assess participant's ability to perform complex grasp tasks: pouring a bottle; opening lids on two sizes of jars; inserting/turning key in lock; manipulating pegs in a pegboard; inserting four sizes of coins into slots; and screwing four sizes of nuts onto bolts
- Psychosocial Impact of Assistive Devices Scale (PIADS) [ Time Frame: At study completion, 10 weeks ]Assesses user opinions of assistive devices across 26 items, describing likelihood of device adoption for regular use and psychosocial effects of use on function independence, well-being, and quality of life. Each item is scored on a 7 point Likert Scale from -3 to 3 with higher scores indicating more positive impact.
- Change in Electromyography (EMG) signal metrics [ Time Frame: 10 weeks ]Metrics derived from noninvasively recorded electromyography activity as the user attempts functional hand movements
- Number of serious adverse events [ Time Frame: 10 weeks ]Assessed by number of incidences
- Setup time (minutes) [ Time Frame: 10 Weeks ]The time it takes to physically don, connect, and calibrate system components
- Canadian Occupational Performance Measure (COPM) [ Time Frame: Week 1, First session ]A 9 item assessment to measure perceived occupational performance of self-care, productivity and leisure. COPM uses semi-structured interview questions to identify activities that the individuals wants, needs or is expected to perform.
