Lower Limb Exoskeleton Gait Rehabilitation Trainer: Restore Walking Confidence After Stroke
Release time:
2026-06-04
In an aging world where stroke incidence continues to rise, lower limb motor dysfunction remains one of the most difficult challenges in rehabilitation medicine. Patients often struggle with difficulty standing, unstable gait, muscle weakness, and fear of falling. These issues severely affect daily life and place a heavy burden on caregivers. Traditional manual-assisted training is labor-intensive, difficult to standardize, and hard to quantify, often resulting in slow progress and loss of patient motivation.

Lower Limb Exoskeleton Gait Rehabilitation Trainer S-RG-E02 integrates intelligent algorithms, ergonomic design, and flexible actuation technology. It offers a professional, intelligent, and safe walking rehabilitation solution for stroke survivors and patients with other lower limb impairments, helping them move from passive assistance toward active, natural walking and renewed confidence in life.

Why Is Post-Stroke Lower Limb Rehabilitation So Challenging?
Following a stroke, patients frequently experience muscle atrophy, joint stiffness, abnormal gait patterns, and reduced proprioception. Conventional therapy typically relies on manual support from therapists, which limits repetition, intensity control, and objective measurement. As a result, recovery is often slow, and patients may become discouraged due to fatigue or fear.
Common Difficulties Include:
- Unsafe transitions from sitting to standing and fear of falling
- Dragging gait, poor knee control, and quick fatigue while walking
- Further muscle decline from prolonged bed rest
- Lack of quantifiable data to optimize personalized treatment plans
How Does the S-RG-E02 Help Patients Recover Effectively?
The S-RG-E02 collects real-time data on lower limb joint angle trajectories, human-machine interaction torque, and plantar pressure through built-in sensors. Intelligent algorithms analyze the patient’s gait and deliver precise assistive torque at the hip and knee joints while supporting active ankle participation. This closed-loop system enables more physiological movement patterns, promotes neuroplasticity, and helps rebuild muscle strength and coordination more effectively than traditional methods.
Core Advantages
- Flexible Actuation + Active Ankle Joint
Provides natural and coordinated movement support, improving gait quality and lower limb coordination while reducing compensatory movements that can lead to secondary injuries.
- Plantar Pressure Monitoring
Tracks foot-ground contact and center-of-gravity shifts in real time, making training data-driven and adjustable for better weight-bearing symmetry.
- Real-Time Trajectory Monitoring
Clearly displays and records hip, knee, and ankle motion and assistance trajectories, allowing therapists to evaluate progress, identify issues early, and fine-tune programs for optimal outcomes.
- Multiple Intelligent Training Modes
Includes continuous walking passive, single-step passive, in-place stepping passive, main-passive, and active modes to suit various recovery stages, from early rehabilitation to advanced functional training.
- Sit-to-Stand Assistance
Delivers coordinated torque from hip, knee, and ankle joints to help patients safely rise from sitting, reducing risks in early training and building confidence step by step.
Patients usually feel steady, comfortable assistance during sessions, making rehabilitation more engaging and less intimidating under professional guidance.
