The A2-2 is an upper-limb rehabilitation robot that simulates human upper-limb movement in a computer-based virtual environment to deliver multi-joint and single-joint training.
Combines exoskeleton-wrapped mechanical support, weight-reduction training, intelligent real-time feedback and interactive rehabilitation games to assist clinical recovery.
Designed for clinical use in stroke, severe brain injury, cerebrovascular disease and post-surgical upper-limb rehabilitation.
Indications
Upper-limb motor dysfunction after stroke
Traumatic brain injury and other neurological disorders
Cerebrovascular disease and malformations
Postoperative rehabilitation of the upper limb
Therapeutic effects
Promotes isolated (selective) movement patterns
Stimulates residual muscle strength
Improves muscular endurance
Restores joint coordination and flexibility
Enhances upper-body motor control and task-related function (ADL)
Facilitates progressive recovery of upper-limb function
