Cycling Device

Development of a Cycling Device for rehabilitation of the lower extremities.
 
With population aging, there is higher susceptibility to strokesand neurodegenerative diseases. These conditions usually have sequels and, therefore, a necessity of rehabilitation. 
Cycling is a type of intelligent rehabilitation, which allows reducing the effort of therapists while assisting patients, allowing rehabilitation sessions of longer duration. It shows strong similarities with walking: it is a cyclical movement, which requires reciprocal flexion and extension of hip, knee, and ankle; and it is characterized by well-coordinated agonists and antagonists muscle activation. Besides, cycling is safe and avoids balance problems, which allows starting rehabilitation in an acute stage.
Feedback corresponds to sensory information provided during or following task performance. I tis categorized as either intrinsic or extrinsic. Intrinsic feedback refers to a person’s self sensory-perceptual information, available during performance of a task or movement. In some cases, intrinsic feedback mechanisms may be compromised due to impaired central sensory functions, for example, after peripheral or central nervous systems injuries, such as stroke. Extrinsic feedback can be given in addition or in substitution of intrinsic feedback. This artificial feedback, provided from an outside source, could be beneficial in improving the motor recovery.
 
Goals:
- Compile the functionalities that a cycling device should have for its application in rehabilitation.
- Explore biofeedback mechanisms in order to promote patient’s recovery, motivation and participation.
- Development of a biofeedback system for symmetry recovery, in hemiparetic patients, based on Electromyography (EMG) and produced Work.
