THE REHABILITATION PURPOSE
TYPE OF MODEL
WALKBOT BENEFIT
• Create natural gait pattern optimal to the patient
• World-first ankle joint motor drive
• More sessions and efficient therapy by automatic leg length adjustment
• Useful training mode
(Interactive, assist training in accordance to the patient)
• Treadmill synchronized with robot (BWSTT mode is possible)
• Bio-feedback, 3D real-time software package
• Clinically proven
WHAT FEATURES / TECHNOLOGY
Preventing toe dragging/ foot drop at the end of stance phase
•Stronger sensory stimulations on the foot
WHAT FEATURES / TECHNOLOGY
Input

WHAT FEATURES / TECHNOLOGY
Basic Training Mode
Follows decided stride and speed
Applicable to early stage
Interactive Training Mode
Therapeutic speed is automatically adjusted as per patient’s muscle power
Applicable to main course of training
Assisted Training Mode
Robot assisted power for abnormal leg is adjusted
Mainly applicable to paralyzed patient
