Types of Robotic Exoskeletons
Robotic exoskeletons for rehabilitation are categorized into various types based on their mechanical operation and intended use. The two primary classifications are active and passive exoskeletons, each designed to serve specific rehabilitation needs.
Active exoskeletons utilize motors and sensors to assist movement actively. These devices adapt to the user’s biomechanics, providing tailored assistance for individuals recovering from conditions like stroke or spinal cord injuries. They offer substantial support, promoting natural movement patterns.
In contrast, passive exoskeletons primarily rely on springs or weights to augment the user’s strength without powered assistance. These devices are less complex and typically used in physical therapy settings to help patients regain mobility and strength through guided movements.
Moreover, rehabilitation-specific designs focus on addressing particular conditions. For instance, some exoskeletons are engineered for gait training, enhancing walking ability in patients with mobility impairments. This diversity in designs and functionalities highlights the evolving landscape of robotic exoskeletons for rehabilitation.
Active vs. Passive Exoskeletons
Active exoskeletons actively assist users by providing powered movements that adapt to the wearer’s motions. These devices utilize motors, sensors, and feedback systems to enhance mobility and support rehabilitation. For instance, the EksoGT is designed for individuals recovering from strokes or spinal cord injuries, facilitating natural gait patterns.
In contrast, passive exoskeletons rely on mechanical systems without any powered assistance. They use springs or other materials to redistribute weight and reduce strain during movement. An example is the back-support exoskeleton, which helps workers lift heavy objects without electrical components.
Both types of robotic exoskeletons for rehabilitation offer unique benefits. Active exoskeletons can significantly enhance users’ potential for recovery, while passive models are typically more affordable and easier to maintain.
