Interventions

  • Eye Tracker — DEVICE
    The intervention consists of two 40-minute training sessions using a customized Digital Training Interface to practice motor primitives for digital activities (clicking, typing, scrolling, drawing). The first session includes an orientation to the eye-tracking device, calibration, and setup adjustments, after which the clinician will confirm feasibility. Training begins with a guided tutorial followed by eight practice levels, each lasting 3 minutes or until 20 correct targets are achieved. Participants are encouraged to complete all levels and focus on challenging primitives. In-clinic and at-home sessions are scheduled on separate days, with a rest period for in-clinic visits, ensuring adequate rest and retention of learned skills.
  • Mouth Operated Joystick — DEVICE
    The intervention consists of two 40-minute training sessions using a customized Digital Training Interface to practice motor primitives for digital activities (clicking, typing, scrolling, drawing). The first session includes an orientation to the mouth-operated joystick device, calibration, and setup adjustments, after which the clinician will confirm feasibility. Training begins with a guided tutorial followed by eight practice levels, each lasting 3 minutes or until 20 correct targets are achieved. Participants are encouraged to complete all levels and focus on challenging primitives. In-clinic and at-home sessions are scheduled on separate days, with a rest period for in-clinic visits, ensuring adequate rest and retention of learned skills.
  • Non-invasive electroencephalogram (EEG) Headset — DEVICE
    The intervention consists of two 40-minute training sessions using a customized Digital Training Interface to practice motor primitives for digital activities (clicking, typing, scrolling, drawing). The first session includes an orientation to the non-invasive EEG headset device, calibration, and setup adjustments, after which the clinician will confirm feasibility. Training begins with a guided tutorial followed by eight practice levels, each lasting 3 minutes or until 20 correct targets are achieved. Participants are encouraged to complete all levels and focus on challenging primitives. In-clinic and at-home sessions are scheduled on separate days, with a rest period for in-clinic visits, ensuring adequate rest and retention of learned skills.
  • Implantable Brain-Computer-Interface — DEVICE
    Participants with an invasive Brain Computer Interface (BCI) implant, primarily recruited via Neuralink, will use the Neuralink N1 or any other implanted BCI. The intervention consists of one 40-minute training session using a customized Digital Training Interface to practice motor primitives for digital activities (clicking, typing, scrolling, drawing). The session begins with setup assistance and calibration to ensure proper positioning. Training includes a guided tutorial followed by eight practice levels, each lasting 3 minutes or until 20 correct targets are achieved. Participants are encouraged to complete all levels and focus on the most challenging primitives. Prior experience with the device justifies the single-session design.
  • Personal Assistive Technology — DEVICE
    Participants already using a personal assistive technology device will complete one 40-minute training session with a customized Digital Training Interface to practice motor primitives for digital activities (clicking, typing, scrolling, drawing). The session begins with setup assistance and positioning. Training includes a guided tutorial followed by eight practice levels, each lasting 3 minutes or until 20 correct targets are achieved. Participants are encouraged to complete all levels and focus on the most challenging primitives. Since the device is already familiar, only a single session is required.
  • Voice Control — DEVICE
    The intervention consists of two 40-minute training sessions using a customized Digital Training Interface to practice motor primitives for digital activities (clicking, typing, scrolling, drawing). The first session includes an orientation to voice control, after which the clinician will confirm feasibility. Training begins with a guided tutorial followed by eight practice levels, each lasting 3 minutes or until 20 correct targets are achieved. Participants are encouraged to complete all levels and focus on challenging primitives. In-clinic and at-home sessions are scheduled on separate days, with a rest period for in-clinic visits, ensuring adequate rest and retention of learned skills.

Study Details

Many individuals with severe motor impairments rely on Assistive Technologies (ATs) or Brain-Computer Interfaces (BCIs) to interact with digital devices such as their computers. Clinicians and researchers currently lack a common framework to objectively quantify how much a given AT or BCI improves real-world function or to compare across tools. This project seeks to address this gap by developing a standardized method to objectively assess or compare the functional benefit of these tools on digital independence, i.e., the ability to independently operate computers, phones, and other digital systems, by creating a unique Digital Assessment Interface (DAI). This assessment will be a simulation of online and digital activities that prior work has determined is important to functional daily living in the digital domain. Participants will complete this assessment with various ATs and BCIs, and these scores will be used to create an index, which will be comprised of performance outcomes, clinician-reported outcomes, and patient-reported outcomes. The tool aims to quantify and compare digital task performance across devices and user populations. The primary objective of this study is to develop an index. The index will quantify functional performance of individuals using various ATs and BCIs. The secondary objectives are to extensively evaluate the psychometric properties of the index, such as the validity, responsiveness, reliability, and floor/ceiling effects both globally and across different devices and impairment levels, ensuring that it can reliably measure the impact of an AT or BCI on a user's ability to independently operate digital systems; and to characterize the familiarization and use of specific BCI and AT systems with reference to a normative healthy control population.

Arms

  • Experimental: AT/BCI User
    Participants in this arm will undergo training and a digital assessment using 3 assistive technologies (eye tracker, mouth-operated joystick, non-invasive electroencephalogram (EEG) headset), brain-computer-interfaces, and applicable personal ATs. Participants will experience each of these devices in a randomized order. Participants in this arm will include individuals with a diagnosis of amyotrophic lateral sclerosis (ALS), spinal cord injury (SCI), or healthy individuals.
