“…One would expect that the corresponding signals X(T ) and X 0 (T ) are drastically different. However, surprisingly, these signals are very close to each other; see, e.g., [1], [5], [8]. This closeness make an automatic detection of motion disorders a difficult task.…”

Abstract-Many neurological disorders result in disordered motion. The effects of a disorder can be decrease by an appropriate rehabilitation. To make rehabilitation efficient, we need to monitor the patient and check how well he or she improves. In our previous papers, we proposed a fuzzy-based semi-heuristic method of gauging how well a patient improved. Surprisingly, this semi-heuristic method turned out to be more efficient that we expected. In this paper, we provide a justification for this efficiency.

“…Empirical data shows that the fuzzy approach is in much better accordance with the doctor's evaluations 1,2,31,39 . This can be explained by the fact that -similarly to airplane maintenance -we want to make sure that the patient performs correctly under all possible circumstances before declaring the therapy a success.…”

In some practical situations -e.g., when treating a new illness -we do not have enough data to make valid statistical conclusions. In such situations, it is necessary to use expert knowledge -and thus, it is beneficial to use fuzzy techniques that were specifically designed to process such knowledge. At first glance, it may seem that in situations when we have large amounts of data, the relative importance of expert knowledge should decrease. However, somewhat surprisingly, it turns out that expert knowledge is still very useful in the current age of big data. In this paper, we explain how exactly (and why) expert knowledge is useful, and we overview efficient methods for processing this knowledge. This overview is illustrated by examples from environmental science, geosciences, engineering (in particular, aircraft maintenance and underwater robots), and medicine.

“…The resulting video capture can then be analyzed using specific software packages to describe, calibrate and quantify the relative movement of the marked positions. Force plates can also be used to collect data of a small number of strides [3], [4], [18]- [20]. Such an approach requires highly specialized and expensive equipment in a controlled and unrepresentative environment, within a large area for the setup of the apparatus.…”

It has been recognized that that the design and prescription of Energy Storing and Returning prosthetic running feet are not well understood and that further information on their performance would be beneficial to increase this understanding. Dynamic analysis of an amputee wearing a prosthetic foot is typically performed using reflective markers and motion-capture systems. High-speed cameras and force plates are used to collect data of a few strides. This requires specialized and expensive equipment in an unrepresentative environment within a large area. Inertial Measurement Units are also capable of being used as wearable sensors but suffer from drift issues. This paper presents the development of a wearable sensing system that records the action of an Energy Storing and Returning prosthetic running foot (sagittal plane displacement and ground contact position) which could have research and/or clinical applications. This is achieved using five standalone pieces of apparatus including foot-mounted pressure sensors and a rotary vario-resistive displacement transducer. It is demonstrated, through the collection of profiles for both foot deflection and ground contact point over the duration of a stride, that the system can be attached to an amputee's prosthesis and used in a non-laboratory environment. It was found from the system that the prosthetic ground contact point, for the amputee tested, progresses along the effective metatarsal portion of the prosthetic foot towards the distal end of the prosthesis over the duration of the stride. Further investigation of the effective stiffness changes of the foot due to the progression of the contact point is warranted.
