Wearable sensors such as smart watches or wrist bands providing positional information can also be applied to solve the occlusion problem in our system.

Patients were eligible for inclusion if they had unilateral hemiplegia caused by ischemic or hemorrhagic stroke. The FMA scoring system using only one Kinect in this study does have some limitations.

Items of the FMA are teest to assess recovery within the context of the motor system. 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 gest below the wrist.

To properly classify motion patterns, features must be extracted from the captured motion data, which contains the positional information of every upper limb joint. The degree of jerky motion was also transformed to jerky scores. Log jerky score in the hemiplegic UE was 1. Data Availability All relevant data are within the paper and its Supporting Information files.

Before the motion was recorded, the therapist entered subject information including recording arm side and the recording assessment item number into the recoding program. The value includes movement times and distance. It is applied clinically and in research to determine disease severity, describe motor recovery, and to plan and assess treatment.

Supervision of technical issues during the study: A few tools in the virtual environment to assess the motor impairment after stroke have been investigated in several prior studies, but the correlations with conventional assessment tools were modest correlation coefficient: Functional assessment tools are essential to monitor recovery and provide current function-based rehabilitation.

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 meye data were log transformed for normalization.

Movement Therapy in Hemiplegia: Demographic and clinical characteristics are summarized in Table 1.

Secondarily, the usefulness of Kinect movement quality analysis was investigated. It is now widely used for clinical assessment of motor function.

Prediction accuracy for each of the 13 items and correlations between real FMA scores and scores using Kinect were analyzed. Further study to validate the usefulness of advanced system in the real home-setting is required.

Review the manuscript and suggest some corrections: Overall process of FMA prediction. Movement smoothness changes during meye recovery. The prediction target of each item score 0, 1 or 2 was evaluated by one therapist. This article has been cited by other articles in PMC. The FMA scoring system using Kinect is valid and provides additional quantitative measures of motion smoothness in stroke patients.

Human motion recognition based on neural network. When tesy to evidence in academic writing, you should always try to reference the primary original source. Reduction to between four and 10 dimensions was done for highly associated principle components.


Angles and distances between two joints for example, hand-shoulder, hand-head and elbow-head are computed from the original position data.

The validation results are averaged over the rounds and derive a more accurate estimate of model prediction performance. This may be associated with barriers including costs, travel and limited use of public transportation due to disabilities. Neurorehabil Neural Repair ; Our cross-validation average error is shown in the prediction accuracy result Fig 2. Authors have also no competing interests relating to employment, consultancy, patents, products in development or modified products along with this patent.

Using conventional validation, such as fixed partitioning the data set, the error of the training set is not a useful estimator of model performance and the error of the test data is not reliable in various testing data sets. Administration of the motor, sensation and balance subscores range from 34 to minutes, with a mean administration time of 58 minutes. Exp Neurol ; Data extraction and normalization of Kinect motion data The recorded joint movement data from each FMA assessment were extracted.

Thirteen of 33 items were selected for upper extremity motor FMA.

The evaluation of the movement impairment in this study is based on the integrated squared jerk. Duration is the length of brunnnstrom clipped data. 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.
