Abstract-Robot-aided gait training can increase the duration and number of training sessions while reducing the number of therapists required for each patient. However, current automated gait trainers do not adapt their movement to the patient's muscular efforts and passive musculoskeletal properties. Furthermore, robot-aided training without therapists lacks the feedback required for patient assessment. In this article, we present results from the literature and our research to provide an overview of novel human-centered strategies for robot behaviors that are patient-cooperative and support motorfunction assessment. Combining robot-aided training with robot-aided assessment will likely make future gait therapy easier, more comfortable, and more efficient. Broad clinical testing is still required for proving this assumption.

“…On the other hand, cadaveric material has limited possibilities to provide feedback on performance and is not always available [9,15]. More recently, several virtual reality simulators were introduced, inspired by the airline industry, which has embraced this technology for decades [6,14,20,21]. Virtual reality trainers have high educational potential due to their capability of providing visual feedback combined with direct feedback on performance after a training session [11].…”

The demand for high quality care is in contrast to reduced training time for residents to develop arthroscopic skills. Thereto, simulators are introduced to train skills away from the operating room. In our clinic, a physical simulation environment to Practice Arthroscopic Surgical Skills for Perfect Operative Real-life Treatment (PASSPORT) is being developed. The PASSPORT concept consists of maintaining the normal arthroscopic equipment, replacing the human knee joint by a phantom, and integrating registration devices to provide performance feedback. The first prototype of the knee phantom allows inspection, treatment of menisci, irrigation, and limb stressing. PASSPORT was evaluated for face and construct validity. Construct validity was assessed by measuring the performance of two groups with different levels of arthroscopic experience (20 surgeons and 8 residents). Participants performed a navigation task five times on PASSPORT. Task times were recorded. Face validity was assessed by completion of a short questionnaire on the participants' impressions and comments for improvements. Construct validity was demonstrated as the surgeons (median task time 19.7 s [8.0-37.6]) were more efficient than the residents (55.2 s [27.9-96.6]) in task completion for each repetition (Mann-Whitney U test, P \ 0.05). The prototype of the knee phantom sufficiently imitated limb outer appearance (79%), portal resistance (82%), and arthroscopic view (81%). Improvements are required for the stressing device and the material of cruciate ligaments. Our physical simulation environment (PASSPORT) demonstrates its potential to evolve as a training modality. In future, automated performance feedback is aimed for.

In this study, to improve accuracy and reproducibility of knee laxity diagnosis, Orthopaedic physical examination assisting system was developed. The system enables the surgeon to monitor the force vector added by himself and the posture of the knee in real-time. The advantage of the developed system is to quantify the normal orthopaedic physical examination, without any modification, which is accustomed to general orthopaedic surgeons. The force vector added to the shank by a surgeon is measured with 3 axis force sensor and 6DOF magnetic tracker FASTRAK, and 6DOF knee joint motion of the patient is measured with two FASTRAK receivers which are attached on its thigh and shank. In this system, to describe the 6DOF knee motion, Femoral and tibial coordinate systems are defined with bony landmark which is easily palpated and are registered to the thigh or shank receiver coordinate system by homogeneous transformation matrix which is acquired by the special stylus. To evaluate the effectiveness of the system, the posterior drawer test with the system was done by 5 young healthy people. The evaluation parameters were knee posture, load magnitude and load position during the experiment. The result showed examination accuracy was significantly improved in all evaluation parameters.
