Hand mobility rehabilitation system A5

wrist mobilityroboticcomputer-assisted

The A5 is a passive-training hand rehabilitation exoskeleton for finger and wrist rehabilitation that simulates human finger and wrist movement rules in real time and runs within a computer-based virtual training environment.

Main functions

• Passive training modes for single finger, multiple fingers, all fingers, wrist only, or combined fingers and wrist.
• Integrated virtual-game environment to support engagement during repetitive training.
• Session query and printing functions for training feedback and documentation.
• Hand exoskeleton supplied in two sets (left and right) to support unilateral or bilateral treatment.

Therapeutic effect

• Supports recovery of hand function and helps prevent muscle atrophy.
• Improves hand muscle strength and endurance through progressive training protocols.
• Enhances coordination of individual finger joints.
• Feedback-based training promotes cortical reorganization and recruitment of compensatory motor areas to aid restoration of hand movement control.

Main indications

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

Contraindications

• Bony malignancy, severe deformation of joint surfaces, spastic paralysis, unstable fractures, uncontrolled infection, and other conditions that contraindicate passive mobilization.

Features

• Wrist control: adjustable wrist range of motion; ability to fix the wrist at an angular position to train fingers alone or to train wrist and fingers simultaneously.
• Composite training: selectable combinations of finger and wrist joint targets to adapt to different patient conditions and rehabilitation goals.
• Multiple integrated training methods and protocols for varied clinical scenarios.
• Software functions for virtual games, data query and printout to support monitoring and documentation of progress.
