Product introduction
SL4-2 is an upper-limb active–passive rehabilitation device controlled by an intelligent system that provides passive, assistive, active and resistive training modes. It is designed to improve joint and muscle function and to support recovery of neuromuscular control through task-oriented and virtual-scenario training.

Short description

• Height adjustment range: 830–940 mm
• Passive mode speed range: 0–60 r/min
• Maximum speed limit range: 61–150 r/min
• Maximum output torque: 1–10 Nm
• Output resistance levels: 0–20 (0–20 Nm)
• Training time range: 1–120 min

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

Unique design

• Frame supports 180° horizontal rotation to vary training orientation
• Height-adjustable structure to fit users of different statures
• Anti-slip, wear-resistant foot pads on the base for stability

Functional advantages

• Multiple training modes: Active, Passive, Assist, Free-switch Active–Passive, Constant-speed, Isokinetic, Orthopedic, Gamified, Custom
• Intelligent detection and automatic switching between active and passive modes according to patient condition
• Spasm/muscle tone monitoring with four adjustable sensitivity levels
• Bidirectional training (forward and backward) with on-the-fly direction switching
• Automatic training report analysis: session duration, travel distance, power and energy consumption
• Intranet IoT connectivity for parameter configuration, equipment status monitoring and report export

Performance features

• Tablet PC with built-in control software for user management and training record storage
• Preset training programs: Standard, Relaxation, Coordination, Strength & Endurance, Gamified Training, Custom
• Isokinetic module for muscle-strength testing and training at constant speed
• Orthopedic mode for reciprocating passive movement within limited ROM after surgery or in restricted mobility
• Interactive gamified exercises to enhance engagement and cognitive-sensorimotor recovery
• Bluetooth cardiopulmonary monitoring (pulse oximeter); system reduces intensity or suspends training on abnormal parameters
