Robot THERY - TEDIRO - The Robotics Platform for Therapy and Diagnostics

Robot THERY with the application THERY UAG accompanies gait training using forearm supports

"Robots, algorithms and AI as colleagues could be considered a useful tool to buffer the effects of staff shortages due to demographic changes and may also help reduce the burden on employees."

Cloud-based Therapy-Management-System (TMS)

Overall progress of the training sessions is being tracked and documented
Insights into gait errors of the patients
Therapy progress data can be exported to the patient's medical record upon completion of the therapy program
Physiotherapists are provided with a personal login for logging into the TMS
Allows for design of clinic-specific training regimens, which may also be adapted to the individual needs of each patient
Training sessions can be scheduled flexibly both during the day and in the evening, at weekends, and on holidays
Before initiating the training program, each patient is provided with an RFID chip for user identification
Robot management system
Privacy: data handling according to the high standards of the GDPR
Server location: Germany; server operator with German headquarter

This is how robot-assisted self-directed training works

Training

Patients log into the robot using their personal RFID chip prior to initiating training session
Robot remembers the patient based on their photo

Start

Patient follows the robot while conducting gait training- robot adapts to the patient's walking speed (up to 0.8 m/s)
Robot provides audio-visual correction recommendations and positive feedback in real time

End

Robot walks patient back to starting position
Robot displays summary of training results

Applications of the mobile robot

THERY has been designed to assists the therapy of gait and mobility disorders following orthopaedic surgical procedures of the lower extremities such as:

total hip arthroplasty (THA), total knee arthroplasty (TKA), femur fractures etc.
corrective osteotomy
cartilage lesions
musculoskeletal injuries etc.

Advantages

Reinforces the patient’s commitment as they are given the opportunity to schedule fixed dates to conduct self-training sessions with the robot
Robot gives correction recommendations while patients practise on their own
In a study using a prototype of our robot, we were able to show that using the robot was associated with following benefits:
- improvement of walking speed *
- 93% of the participants (patients following hip surgery) would recommend the robot-assisted training to their friends and relatives **.
- Based on their experience of using the robot in the acute hospital setting, all patients would be willing to continue this type of training as part of a follow-up treatment during in- or outpatient rehabilitation
