A6 Arm Rehabilitation and Assessment Robotics

The A6 Arm Rehabilitation and Assessment Robotics system represents an advanced upper limb training device based on neural system restoration theory. Featuring a robotic exoskeleton design, the A6 enables both passive and active training for patients with arm dysfunction, supporting rehabilitation from zero muscle strength through functional recovery.

Product Overview

The A6 addresses a critical gap in upper limb rehabilitation: patients in early recovery phases often lack sufficient strength to move their arms voluntarily, yet early mobilization is important for optimal outcomes. By combining passive movement capabilities with progressive active training modes, the A6 accommodates patients across the entire recovery spectrum.

The system is suitable for patients with arm dysfunction caused by central nervous system diseases (stroke, traumatic brain injury, spinal cord injury), peripheral nerve conditions, and musculoskeletal problems requiring upper limb rehabilitation.

Key Features

For patients with stroke, spinal cord injury, or peripheral nerve conditions, Yeecon’s A6 provides CE-certified exoskeleton-assisted arm rehabilitation from zero muscle strength through functional recovery.

• Robotic Exoskeleton Architecture: Wearable arm support structure that can either drive patient limb movement or respond to patient-initiated motion
• Multi-dimensional Movement: Enables passive and active arm movement in multiple spatial planes
• Situational Interaction: Virtual scenarios integrated with training activities
• Feedback Training System: Real-time performance feedback during exercises
• Powerful Evaluation System: Full assessment capabilities for therapist planning
• Zero Muscle Strength Training: Enables training for patients without voluntary movement ability

Training Modes

Trajectory Training Mode

For patients in early rehabilitation phases, therapists can set 3-minute training protocols simulating daily activity movements. The system learns and records training trajectories set by the therapist, then the robotic arm drives the patient’s upper limb through passive trajectory reduction training. This approach helps eliminate edema, prevent muscle atrophy, and maintain range of motion.

Guidance Mode

The system can adjust the guiding force of the exoskeleton to each joint of the patient’s arm. Patients use their own strength to complete training, stimulating rehabilitation of residual muscle capacity. This mode bridges passive and fully active training.

Active Mode

The patient drives the robotic exoskeleton to move in any direction. Therapists select corresponding interactive games, and patients perform single joint or multi-joint training. Active mode enhances patient initiative and accelerates the rehabilitation process.

Prescription Mode

This mode focuses on training for activities of daily living, preparing patients to resume functional tasks encountered in everyday life.

Technical Approach

Based on neural system restoration theory, the A6 provides:

• Multi-joint Control: Adjustable assistance at each upper limb joint
• Trajectory Recording: Therapist-defined movement patterns stored for consistent repetition
• Progressive Challenge: Gradual reduction of assistance as patients improve
• Functional Task Training: Movement patterns relevant to daily activities

Clinical Applications

The A6 targets patients with arm dysfunction from various causes:

• Central Nervous System Damage: Stroke, traumatic brain injury, spinal cord injury, neuropathy
• Peripheral Conditions: Peripheral nerve damage affecting upper limb function
• Musculoskeletal Issues: Muscle or bone diseases requiring arm rehabilitation
• Post-surgical Recovery: Upper limb function restoration following surgical procedures

Treatment goals include increasing muscle strength, expanding joint range of motion, and improving overall motor function.

Assessment Capabilities

The A6 includes evaluation functions that assist therapists in creating individualized rehabilitation plans. Assessment data contributes to evidence-based treatment planning and progress monitoring throughout the rehabilitation process.

Frequently Asked Questions

How does the A6 differ from the A2 system?

While both address upper limb rehabilitation, the A6 features a more advanced robotic exoskeleton design with greater capabilities for both passive and active training. The A6 includes trajectory recording functions, multiple training modes (trajectory, guidance, active, prescription), and is specifically designed to accommodate patients with zero muscle strength through to functional recovery.

Can patients with no arm movement use the A6?

Yes, the A6 is specifically designed to support rehabilitation starting from zero muscle strength. In trajectory training mode, the robotic exoskeleton fully drives the patient’s arm through therapist-defined movement patterns, providing passive mobilization for patients who cannot yet generate voluntary movement.

What neurological conditions can the A6 address?

The A6 is appropriate for arm dysfunction caused by stroke, traumatic brain injury, spinal cord injury, peripheral neuropathy, and other conditions affecting the central or peripheral nervous system. It can also address musculoskeletal conditions and post-surgical rehabilitation needs.
