New robotic rehabilitation solution

Early Walking, Better Recovery

Early walking training not only reduces bedridden complications, but also allows users to regain walking and balance ability. It enhances their mobility and daily quality of life. 

As part of standard hospital rehabilitation, the HIWIN Robotic Gait Training System improves clinical functional outcomes in acute stroke patients [1].

It is recommended that patients with limited ambulatory ability consider incorporating robot-assisted gait training into their rehabilitation programs.

The HIWIN Robotic Gait Training System offers a cost and labour-efficient treatment strategy.

Hybrid Robotic-Assisted Gait Training System

MRG-P100 is a hybrid of end-effector and exoskeleton systems. 

With the end-effector system, movement is generated from the most distal segment of the extremity. The gait cycle is multi-programmable and driven by footplates in a closed-chain pattern. 

In the exoskeleton system, there is a one-to-one correspondence between robots and the patient’s joints, and each single joint is guided along a pre-programmed trajectory. 

The hybrid combines the best of both methods. The patient transfer system includes a retractable ramping plate and power rise assistance to assist with patient transfers.

1. The transfer system includes a retractable ramp plate and electric body lifting device. 

2. The 3-point support system (non-suspension system) includes abdominal support, supportive knee caps and a rear buttock block. 

3. The intelligent monitor system includes setting the individual user’s basic data, thigh (upper leg) and calf (lower leg) lengths, and training parameters.

3-Point Support System

It consists of a three-point support system, exoskeleton modules and footplates.

When standing on the machine, the patient’s abdomen contacts the abdominal support from the front.

The hip block from the rear prevents the patient from falling backwards. The knee pad/support from the front helps to prevent knee buckling.

The 3-point support (abdomen, pelvis, and knees) enables the patient to receive weight-bearing training in a more comfortable environment, with no need for a suspension harness. 

The peddling cycle is driven by two coordinating footplates and is secured by the exoskeletal modules. 

Gait Patterns for Personalized Training

The padel trajectory was based on an elliptical trainer because its trajectory was shown to have similar motion to a normal walking pattern [2]

The program predetermines the trajectory according to different leg lengths.

The trajectory can be adjusted automatically by selecting a desired step length which is presented as the percentage of the maximum step length preset by the program. 

Facilitate Motor Recovery

The Robotic Gait Training System enables the patient to stand while performing passive leg motions that mimic the gait cycle. The system may help to facilitate functional motor recovery of the paretic leg.

The system is practical, safe, and suitable to use in patients with substantial leg dysfunction. [3]. 

Improvement in Balance, Gait and Brainwave Oscillations

Personalized gait patterns help to deliver intensive training in order to enhance neuroplasticity. 

A 2020 study of 12 chronic stroke patients found that after four weeks of treatment alongside standard therapy, there was a significant improvement in balance ability, gait cycle duration and brainwave oscillation. 

The event-related synchronization (ERS) was significantly decreased in post-stroke patients [4]. 

3-Month Follow-Up

In a 2022 study of 20 subacute stroke patients, after four weeks of treatment involving 20 sessions with the HIWIN Robotic Gait Training System alongside conventional therapy, there was significant improvement in motor control after 3 month follow up [5].
