Elbow rehabilitation robot

Elbow Rehabilitation Robot

This technology is an elbow rehabilitation device that measures the stiffness of a patient's elbow joint and performs rehabilitation training by controlling the speed of the drive motor based on torque values.

Conventional rehabilitation robots struggle with precise operational control based on a patient's stiffness and lack adequate response to sudden spasms, posing a risk of injury to the patient.

This technology uses a torque sensor to measure the load applied to the elbow and its instantaneous changes in real-time, while a rehabilitation control unit variably adjusts the motor's rotation angle and speed according to the patient's condition. Applicable to rehabilitation training, gait assistance, and medical/welfare services, it provides a robot capable of adjusting treatment based on the patient's condition and mobility, thereby improving the effectiveness of rehabilitation therapy for stroke patients with elbow stiffness.

Key Features:

• A torque sensor connected to the forearm rotation reducer that measures the torque applied to the elbow area when the patient's elbow is extended by the operation of the forearm drive motor.
• A forearm exercise unit coupled to the shaft end of the forearm rotation reducer that supports the patient's forearm.
• An upper arm support unit coupled to the base frame that supports the patient's upper arm.
• A rehabilitation control unit that regulates the operation or rotation speed of the forearm drive motor.
