In order to solve this issue, we generated integrated jerky motion data that were dimensionless. Retrieved from ” https: The post-stroke hemiplegic patient. It is brunnstrmo clinically and in research to determine disease severity, describe motor recovery, and to plan and assess treatment.

Duration is the length of the clipped data. Data recorded at the start and end of each motion were meher by thresholding of the joint distance between frames. Physiopedia is not a substitute for professional advice or expert medical services from a qualified healthcare provider. Items of the FMA are intended to assess recovery within the context of the motor system. The Fugl-Meyer scale has only three levels of assessment for each item. Results Characteristics of the patients Among 44 patients who agreed to participate, 41 completed the FMA.

For the left arm, as an example, left hand, left wrist, left elbow, left shoulder, shoulder center and head joint position data were extracted. When the motor scale is administered on its own, it takes approximately 20 minutes to complete.

Fugl-Meyer was particularly influenced by the paper authored by Thomas Twitchell, titled The Restoration of Motor Functioning Following Hemiplegia in Man [8] and observations on post-stroke patients by Signe Brunnstrom.

An integrated jerky motion varies greatly with the duration and length distance of the movement. Topics in Stroke Rehabilitation.

However, the best way to solve this problem is to gather the more patient data. Secondarily, the usefulness of Kinect movement quality analysis was investigated.

FMA scoring based on pattern recognition from Kinect data To predict a FMA score for each assessment item, an artificial neural network ANN among various pattern recognition algorithms was adopted.

Functional tasks are not incorporated into the evaluation. The maximum total score that can be obtained in Fugl Meyer assessment isthough it is common practice to assess all domains separately. Although we used the data from 41 stroke patients with various motor impairments, decrease of fuvl imbalance by collecting more data sets and adoption of the above techniques could help increase prediction accuracies.

More and varied movement data of each assessment item would increase the precision of the FMA system score using Kinect. Jerk t is an 18 dimensional vector because subject motion data tedt 18 variables six joint x three dimension. A score of 1 is given when the task is performed partially and a score of 2 is given when the task is performed fully.

Scandinavian Journal of Rehabilitation Medicine. Role of the cerebellum and basal ganglia in voluntary movement. The evaluation of the movement impairment in this study is based on the integrated squared jerk.

The FMA scoring system using only one Kinect in this study does have some limitations.

The motor domain includes items assessing movement, coordination, and reflex action of the shoulder, elbow, forearm, wrist, hand, hip, knee, and ankle. Introduction Stroke is a leading cause of disabilities worldwide[ 1 ] and hemiplegia is the most common impairment after stroke, [ 2 ] resulting in upper extremity UE dysfunction. In further work, web-based uploading system of FMA Kinect motion data and real FMA data in various area could help acquire more patient data.

The Kinect depth-sensing camera was operated with a frame-rate of 30Hz and was positioned in front of each subject to track the entire arm during FMA motions.

Kinect is a relatively inexpensive depth-sensing camera and no additional space and devices are required. Wearable sensors such as smart watches or wrist bands providing positional information can also be applied to solve the occlusion problem in our system.

The validation results are averaged over the rounds and derive a more accurate estimate of model prediction performance. Lancet Neurol ; 6: A smooth curve movement like A has a lower jerky score value, whereas a high trembling curve like B has a higher jerky motion score. To remove the differences of seating locations and to normalize body size, all joint data were transformed by minus of initial shoulder center and by dividing the summation of each body length i.


Supporting Information S1 Appendix Data clipping. The dimensionless value therefore made the original data comparable. A home-based virtual rehabilitation system could be a useful alternative for conventional rehabilitation to overcome barriers for outpatient rehabilitation in stroke patients, considering its low cost and greater accessibility.

Data file used for analysis. However, a different number of principal components were selected for each assessment after PCA dimensionality reduction. Fully-automated test of upper-extremity function. The k-fold means that the sample is randomly partitioned into k subsamples. Parkinsonism reduces coordination of fingers, wrist, and arm in fine motor control.

A supervised learning approach for imbalanced data sets. Administration of the motor, sensation and balance subscores range from 34 to minutes, with a mean administration time of 58 minutes.

Furthermore, use of a cloud computing system with machine learning ability, such as Microsoft Azure ML, Amazon Machine Learning or IBM Watson Analytics, will facilitate develop of a prediction model capable of self-learning whenever new patient data is uploaded, and to predict FMA score using the model in the absence of a specialist.

Traditional Brunnstrom recovery phase reveals the recovery of coordinated movement and emergence from synergistic movements. An analysis of the precision and reliability of the leap motion sensor and its suitability for static and dynamic tracking.

Log transformed jerky mwyer were significantly higher in the brunnstromm side 1.
