The main contributions of our proposed method are summarized as follows: Presenting an interpretable model based on clinical features. Therefore, experts can verify the decision Analysis of gait dynamics is a noninvasive and totally painless test, and it can be an ideal method for the diagnosis of neurodegenerative diseases. To have an interpretable system, 10 clinical features are extracted from the vGRF signal. Epub 2017 Dec 1. Sensors 2014, 14, 6891-6909. In addition, a 10-point median filter is applied to remove some fluctuations which can causes non-zero vGRF values during the swing phases. Therefore, using the interval type-2 fuzzy logic increases the robustness of the extracted fuzzy rules against the noisy data. This book delivers hopeful, helpful, and extensive information to all parties concerned: patients, caregivers, and doctors. In addition to recording of baseline parameters during preferred walking velocity, subjects were required to vary velocity from very slow to very fast.

Shahid Beheshti University Gait analysis in three different 6-hydroxydopamine rat models of Parkinson's disease. The striking features of gait impairments in PD are characterized by bradykinesia ( 1 ), akinesia ( 1) and freezing ( 2 ). This chapter deals with the neuronal mechanisms underlying impaired gait. Parkinson’s disease (PD) is a complex and progressive disorder characterized by various motor and non-motor symptoms. Although a number of studies compared single … On the other hand, if the system detects a patient as a healthy person, it would be dangerous for his/her health. First, high-level features explaining the behavior of the gait cycle obtained from wearable sensors are extracted. These practice guidelines draw upon the widest relevant knowledge and evidence available to describe and inform contemporary best practice occupational therapy for people with Parkinson's disease. Gait impairments are a common and early feature of Parkinson’s disease (PD) and are a major cause of functional dependence, falls and mortality.

The aim of this review is to summarize that most relevant technologies used to evaluate gait features and the associated algorithms that have shown promise to aid diagnosis and symptom monitoring in Parkinson’s disease (PD) patients. To investigate the effectiveness of the proposed Interval Type-2 Fuzzy system against noisy data, its performance is compared with a type-1 fuzzy neural network applying on noisy test samples. To determine the consequent part parameters yi for ith fuzzy rule, a weighted average of desired outputs of training samples belongs to the ith cluster is calculated as follows: where y∗k is desired output value for kth training sample, ui,k is the fuzzy membership value of kth training sample to the ith cluster calculated during the clustering, N is the number of training samples, and m>1 is the fuzzy partition exponent for controlling the degree of fuzzy overlap in FCM algorithm.

Epub 2017 Sep 28. 8600 Rockville Pike Following [35], each sub-dataset is divided into training and testing sets according to the leave-one-out cross-validation procedure. Parkinson’s disease symptoms also include speech disorders as well as cognitive impairments. Patient presentations, gait analysis, gait training exercises and rehab techniques are filmed with studio-quality, multi-camera angles. These centers are used as the centers of fuzzy sets composing each fuzzy rule. For parameter setting, we should determine the number of fuzzy rules and the width of fuzzy sets. We determine these parameters by applying a centroid-based clustering method, like Fuzzy C-Means [6] on training samples as follows: Divide the training samples into R clusters. If the coverage of existing fuzzy rules is not sufficiently encountering a new example, a new fuzzy rule is added to the Fuzzy Neural Network to cover an area consisting of this new sample and future similar instances. share, This research is about the development a fuzzy decision support system f... ∙ ∙ We conclude that the presented solutions produce accurate results and can capture clinically relevant parameters using commodity wearable sensors or a simple smartphone.

In this part, whole available samples are fed to the Interval Type-2 Fuzzy Neural Network to extract final fuzzy rules based on the currently available data. Motor assessment of Parkinson`s Disease can be divided into clinimetrics, assessment of balance and posture, arm and hand function, and gait/walking. Background: The dataset used includes data from three PD research studies [62, 20, 27]. One of the most popular metrics in classification tasks is "Accuracy" that shows the average performance of the method to properly classify instances and is defined as follows: where TP ("True Positive") is the number of instances that belongs to the positive class (here PD patient) classified correctly, TN (True Negative) is the number of instances belongs to the negative class (here healthy persons) classified correctly, FP (False Positive) is the number of instances belongs to the negative class but classified wrongly, and finally, FN (False Negative) is the number of instances belonging to the positive class but classified wrongly. 01/13/2021 ∙ by Melanie F.
