The Fugl-Meyer Assessment (FMA) is a stroke-specific, performance-based following stroke and integrates Brunnstrom’s stages of motor recovery (Gladstone et al. This method of assessment reduces the time required to perform the test.

Length is the maximum distance of a position vector time t from the initial time T 1which is the greatest difference of motion distance from the start of motion.

Subject motion was recorded simultaneously by Kinect for all 13 items. S2 Appendix Dimensionality reduction. Contents Editors Categories Share Cite. Total score of FMA for selected items ranged from 0 to While waiting for a more advanced form of Kinect, another solution is fusion with other hand tracking sensor, such as the Leap Motion device Leap Motion, USAwhich allows precise hand tracking using a hand point cloud below the wrist.

One is the occlusion of the body part during tracking by Kinect. Development and validation of a short form of the Fugl-Meyer motor scale in patients with stroke.

This article has been cited by other articles in PMC. For instance, Kinect can not track the hand when it is moved to the lumbar spine for FMA.

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. Assessing upper extremity motor function in practice of virtual activities of daily living.


This research protocol was approved by the Seoul National University Bundang Hospital institutional review board and was conducted in accordance with the regulatory standards of Good Clinical Practice and the Declaration of Helsinki World Medical Association Declaration of Helsinki: An identical ANN structure i.

In one previous study, scores calculated from motion data captured by Kinect correlated well with the motor scores in chronic stroke patients.

Scoring is based on direct observation of performance. One occupational therapist assessed the motor FMA while recording upper extremity motion with Kinect.

However, a different number of principal components were selected for each assessment after PCA dimensionality reduction.

Fugl-Meyer Assessment of sensorimotor function – Wikipedia

Motion data recording program. Rehabilitation Measures Database Further study to validate the usefulness of advanced system in the real home-setting is required.

The movement of the joint center was used for the Jerky motion analysis. In machine learning and cognitive science, ANNs are statistical learning models inspired by biological neural networks that have become popular in solving various problems in diverse fields.

Outpatient rehabilitation among stroke survivors—21 States and the District of Columbia, The individual in Fig 1 provided written informed consent as outlined in the PLOS consent form to publish the picture.

Gait quality assessment using self-organising artificial neural networks. S1 File Data file used for analysis. The Fugl-Meyer Assessment scale is an ordinal scale that has 3 points for each item. Scandinavian Journal of Rehabilitation Medicine. Please review our privacy policy.

One occupational therapist with two-year experience in the FMA test did the evaluations. This page was last edited on 31 Augustat The k-fold means that the sample is randomly partitioned into k subsamples.


Degree of jerky motion Jerky scores during flexion synergy motion instructed to fully supinate the forearm, flex the elbow, and bring the hand to the ear on the opposite side of FMA calculated from Kinect motion data were log transformed for normalization. Centers for Disease Control and Prevention. When the motor scale is administered on its own, it takes approximately 20 minutes to complete.

However, Fugl-Meyer test still holds good, possibly because it follows a hierarchical scoring system based on the level of difficulty in performing the tasks. Fully-automated test of upper-extremity function.

Jerky scores during the motion for flexion synergy in FMA were used for analysis. Functional tasks are not incorporated into the evaluation.

Fugl-Meyer Assessment of Motor Recovery after Stroke

Stroke Assessment and evaluation instruments. The motor domain includes items assessing movement, coordination, and reflex fuyl of the shoulder, elbow, forearm, wrist, hand, hip, knee, and ankle.

Log jerky scores between hemiplegic and non-hemiplegic side were compared using paired t-test. Reduction to between four and 10 dimensions was done for brnunstrom associated principle components. Authors have also no competing interests relating to employment, consultancy, patents, products in development or modified products along with this patent. A method for evaluation of physical performance. Techniques explored to solve the imbalance issues include re-sample techniques,[ 28 ] adaptive training algorithms,[ 29 ] particle swarm optimization[ 30 ] and parameter searching.
