Arm mobility rehabilitation system SL4-3

leg mobilitylimbs mobilitycomputer-assisted

Product Introduction
SL4-3 is an intelligent active-passive rehabilitation device for upper and lower limbs. Controlled by adaptive programs with feedback regulation, it provides passive, assistive, active and resistive training to improve joint and muscle function. The system can operate with the integrated electrical stimulation module for combined neuromuscular therapy to support recovery of motor control.

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 orthopedic rehabilitation.

Short Description

• Upper-limb trainer height adjustment range: 830–940 mm
• Lower-limb pedal distance: 17 cm
• Maximum speed limit range: 61–150 r/min
• Output resistance: 0–20 levels (0–20 Nm)
• Training time: 1–120 min
• Electrical stimulation pulse width: adjustable 20 μs – 500 μs

Functional Features

• Digital patient information management — electronic patient records with storage and printing of training and assessment data
• Assessment module — built-in pain evaluation and isokinetic muscle-strength testing for objective tracking of progress
• Isokinetic training mode — integrated isokinetic strength training and testing to measure peak muscle force at constant speed
• Orthopedic training mode — reciprocating passive motion within a customizable range, suitable for post‑surgical and mobility‑restricted patients
• Prescriptive training mode — preset programs for relaxation, strength, coordination and bilateral limb linkage
• Gamified rehabilitation training — interactive games to increase patient engagement and support motor-cognitive recovery
• Software interface — Tablet PC terminal with seven built‑in modes (Standard, Symmetric Game, Spring Resistance Game, Relaxation, Strength & Endurance, Coordination, Multi‑player Competitive); multiple units can be networked for group training
• Cardiopulmonary monitoring — Bluetooth pulse oximeter for continuous heart rate and SpO2 monitoring; system can reduce resistance or stop exercise if abnormal values are detected
