Hand mobility rehabilitation system A5

roboticvirtual

The A5 is a passive training hand rehabilitation robotic exoskeleton designed for finger and wrist rehabilitation, providing interactive virtual-game training and comprehensive passive training modes for single fingers, multiple fingers, all fingers, wrists, and combined finger-wrist therapy.

Overview and capabilities:

• Passive training that simulates human finger and wrist movement rules in real time.
• Compound passive modes: single-finger, multi-finger, all-fingers, wrist-only, and combined finger-and-wrist training.
• Interactive virtual games plus session query and print functions for patient engagement and therapy documentation.

Therapeutic effect:

• Supports recovery of hand function and helps prevent disuse atrophy.
• Improves hand muscle strength and endurance through progressive training protocols.
• Enhances coordination across finger joints.
• Feedback-based training aids cortical reorganization and restoration of motor control.

Main intended uses:

• Rehabilitation of joint function after hand and wrist injuries.
• Recovery of stiffness and function after hand surgery.
• Training of hand and wrist activities of daily living (ADL) after central nervous system injury.

Contraindications (selected):

• Bone malignancy, severe articular surface distortion, spastic paralysis, unstable fractures, uncontrolled infections and other conditions where passive robotic training is contraindicated.

Key features:

• Wrist control: independent range-of-motion control and capability to fix the wrist at an angular position to isolate finger training or combine finger-and-wrist training.
• Configurable compound hand training: selectable joint combinations and multiple integrated methods to address varied clinical presentations.
