Product Introduction
SL4-3S is an intelligent active-passive rehabilitation device for upper and lower limbs. The system uses program-controlled drive and feedback regulation to deliver passive, assistive, active and resistive training to limb joints and muscles. An integrated electrical stimulation module can be used concurrently to provide synergistic therapy that supports neuromuscular re-education. Multiple preloaded programs cover standard rehabilitation, relaxation, strength & endurance and coordination. Task-oriented virtual scenarios are available to target motor control patterns and improve functional outcomes.

Clinical Application
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 patients.

Functional Features

• Digital patient management: electronic records store and print training and assessment history.
• Assessment module: built-in pain scales and isokinetic muscle strength testing to quantify function and track progress.
• Isokinetic training mode: integrated isokinetic strength testing and training to enable peak muscle force at constant speed.
• Orthopedic/passive mode: reciprocating passive motion within customizable ROM limits for post‑operative or mobility-restricted patients.
• Prescriptive training programs: preset protocols for relaxation, strength, coordination and bilateral linkage for standardized rehabilitation.
• Gamified rehabilitation: rehabilitation games to increase patient engagement and promote motor‑cognitive recovery.
• Software interface: tablet PC terminal with seven built-in training modes; supports multi‑unit interconnection for group training.
• Cardiopulmonary monitoring: Bluetooth pulse oximeter for continuous heart rate and SpO2 monitoring; the system reduces resistance or stops training if abnormal parameters are detected.
