Leg mobility rehabilitation system SL4-1

limbs mobilitycomputer-assistedwith serious games

Product Introduction
SL4-1 intelligent lower limb active-passive rehabilitation device is controlled by an embedded intelligent system to provide passive, assistive, active and resistive training for patients' lower limbs. It supports joint and muscle function recovery and facilitates neuromuscular control restoration. The system includes preset programs for standard rehabilitation, relaxation, strength & endurance, coordination and task-oriented virtual-scenario training to stimulate motor control patterns.

Clinical Application
Indicated for functional rehabilitation of upper and lower limbs in neurological and orthopedic conditions including stroke, traumatic brain injury, spinal cord injury, cerebral palsy, Parkinson's disease, multiple sclerosis, sports injuries and post-operative orthopedic cases.

Unique Design

• Upper limb frame with 180° horizontal rotation support
• Height-adjustable to accommodate users of different statures
• Anti-slip, wear-resistant rear foot pads on the base for stability

Functional Advantages

• Multiple training modes: Active, Passive, Assist, Switchable Active-Passive, Constant-Speed
• Intelligent detection of patient status with automatic switching between active and passive modes
• Spasm monitoring for upper and lower limb muscle tension with four adjustable sensitivity levels
• Bilateral training directions (forward and backward) with in-session direction switching
• Automatic training report generation (total duration, travel distance, power, energy consumption, etc.)
• Intranet/IoT connectivity for parameter configuration, device status monitoring and report export

Performance Features

• User management: Tablet PC with built-in control software for user profiles and training record storage
• Preset training programs: Standard, Relaxation, Coordination, Strength & Endurance, Gamified Training and Custom Training
• Isokinetic mode: Professional isokinetic muscle strength training and testing module enabling maximum force at constant speed
• Orthopedic mode: Reciprocating passive movement within a limited range for post-operative or limited-mobility patients
• Gamified training: Interactive games to increase engagement and support cognitive/sensory recovery
• Cardiopulmonary monitoring: Bluetooth pulse oximeter for continuous heart rate and SpO2 monitoring with automatic intensity reduction or training suspension on abnormal readings
