Children with spastic cerebral palsy suffer from significant weakness that contributes to abnormal posture and movement. It is thought that this arises due lack of frequency sufficient tension to encourage normal muscular growth underlying the need for early intervention to encourage walking. The failure of muscle growth to keep pace with bone growth is most evident in the bi-articular muscles and contributes to joint contractures and gait abnormalities such as toe-walking and flexed-knee gait.

Recently, our research team has developed a novel, lightweight (0.2kg at knee joint) and portable (energetically autonomous) Soft Wearable Robotic Knee System that can provide active powered knee assistance and synchronized proprioceptive feedback for the gait training of stroke patients' standing and walking.
