Robotic Controllers for Motor Learning After Neurological Injuries
(HRCEML Trial)
Trial Summary
What is the purpose of this trial?
The purpose of this study is to develop a new paradigm to understand how humans physically interact with each other at a single and at multiple joints, with multiple contact points, so as to synthesize robot controllers that can exhibit human-like behavior when interacting with humans (e.g., exoskeleton) or other co-robots. The investigators will develop models for a single joint robot (i.e. at the ankle joint) that can vary its haptic behavioral interactions at variable impedances, and replicate in a multi-joint robot (i.e. at the ankle, knee, and hip joints). The investigators will collect data from healthy participants and clinical populations to create a controller based on our models to implement in the robots. Then, the investigators will test our models via the robots to investigate the mechanisms underlying enhanced motor learning during different human-human haptic interaction behaviors (i.e. collaboration, competition, and cooperation. This study will be carried out in healthy participants, participants post-stroke, and participants with spinal cord injury (SCI).
Do I need to stop taking my current medications to join the trial?
The trial information does not specify whether you need to stop taking your current medications. However, it mentions that participants should not have concurrent medical treatments, which might imply some restrictions. It's best to discuss your specific medications with the trial coordinators.
What data supports the effectiveness of the treatment Human-like Robotic Controllers, Co-Robot Controllers, Exoskeleton-based Dyadic Interaction Infrastructure for motor learning after neurological injuries?
Research shows that robotic systems, including exoskeletons, can help with motor recovery by providing repetitive and task-oriented practice, which is important for relearning movements after neurological injuries. Studies suggest that these systems can be as effective as traditional therapy methods, promoting motor relearning and functional restoration.12345
Is the use of robotic controllers for motor learning after neurological injuries safe for humans?
Research suggests that robotic controllers, such as exoskeletons, are generally safe for use in rehabilitation, as they have been part of clinical practice for over a decade and are designed to ensure safe physical interaction with users. Preliminary studies, including those involving stroke patients, indicate that these systems are feasible and safe for use in rehabilitation settings.12678
How does the robotic controller treatment for motor learning after neurological injuries differ from other treatments?
This treatment is unique because it uses robotic controllers that adapt to the patient's recovery stage, providing personalized, task-oriented rehabilitation. Unlike traditional therapies, it emphasizes 'assist-as-needed' support, encouraging patients to actively participate in their recovery by only providing help when necessary, which can enhance motor learning and functional restoration.123910
Eligibility Criteria
This trial is for individuals aged 18-80 with normal hearing and vision, who can understand English and give informed consent. It's suitable for healthy participants as well as those post-stroke or with spinal cord injury (SCI), provided they can walk over 10m independently. People with brain lesions, neurological disorders, abnormal limb movements, or outside the height range of 3'6" to 6'2" cannot join.Inclusion Criteria
