Brief summary

Determination of clinical effects of brain machine interface in chronic stroke patient without wrist extensor strength

Detailed description

The purpose of this study is to compare RecoveriX with individual EEG calibration and without individual EEG calibration to determine the clinical effect of brain machine interface in chronic stroke patient without wrist extensor strength

Interventions

DEVICEExperimental: RecoveriX with individual EEG calibration

RecoveriX applied FES according to individual brainwave by individual EEG calibration for 5 times a week for 4 weeks

DEVICERecoveriX without individual EEG calibration

RecoveriX applied FES according to the brainwave of other subjects regardless of the individual brainwave for 5 times a week for 4 weeks

Design outcomes

Primary

MeasureTime frameDescription
Fugl-Meyer Assessment - upper extremity4 weeks after baselineFugl-Meyer Assessment is indicator of the level of impairment of upper extremity, with higher scores indicating lower impairment. Total scores range from 0 to 66, each item being scored on a 3-point scale (0, cannot perform; 1, partially performs; and 2, fully performs the task).

Secondary

MeasureTime frameDescription
Jebsen hand function testbaseline, 2 weeks after baseline, 4 weeks after baseline, 8 weeks after baselineJebsen hand function test provides a standardized and objective evaluation of fine and gross motor hand function using simulated activities of daily living. Total score is the sum of time taken for each subtest, which are rounded to the nearest second. Shorter times indicate better performance.
9-hole peg testbaseline, 2 weeks after baseline, 4 weeks after baseline, 8 weeks after baseline9-hole peg test measures finger dexterity in patients with stroke. Scores are based on the time taken to complete the test activity, recorded in seconds.
Medical Research Council (MRC) scale of affected upper extremitybaseline, 2 weeks after baseline, 4 weeks after baseline, 8 weeks after baselineThe MRC is a standardized set of assessments that measure muscle strength and function. The MRC scale of muscle strength uses a score of 0 to 5 to grade the power of a particular muscle group in relation to the movement of a single joint.
Joint position sensebaseline, 2 weeks after baseline, 4 weeks after baseline, 8 weeks after baselineJoint position sense is tested by holding the most distal joint of a digit by its sides and moving it slightly up or down. First, demonstrate the test with the patient watching so they understand what is wanted then perform the test with their eyes closed.
Sensation of limb movementbaseline, 2 weeks after baseline, 4 weeks after baseline, 8 weeks after baselineFor the ability to sense a sharp object, the best screening test uses a safety pin or other sharp object to lightly prick the face, torso, and 4 limbs; the patient is asked whether the pinprick feels the same on both sides and whether the sensation is dull or sharp.
active range of motion (AROM) of wrist flexion/extensionbaseline, 2 weeks after baseline, 4 weeks after baseline, 8 weeks after baselineactive range of motion of wrist flexion and extension
Box and block testbaseline, 2 weeks after baseline, 4 weeks after baseline, 8 weeks after baselineBox and block test measures unilateral gross manual dexterity. Higher scores indicate better gross manual dexterity.
Stroke impact scalebaseline, 2 weeks after baseline, 4 weeks after baseline, 8 weeks after baselineStroke impact scale evaluates how stroke has impacted your health and life. Each item is rated in a 5-point Likert scale in terms of the difficulty the patient has experienced in completing each item. Summative scores are generated for each domain, scores range from 0-100.
electroencephalography (EEG) effective connectivitybaseline, 2 weeks after baseline, 4 weeks after baseline, 8 weeks after baselineEEG effective connectivity describes the causal influences that neural units exert over another.
Stroke rehabilitation motivation scalebaseline, 2 weeks after baseline, 4 weeks after baseline, 8 weeks after baselineStroke rehabilitation motivation scale includes 28 items applicable to stroke rehabilitation, adapted from the Sports Motivation Scale. The response to each item is measured on a scale of 1 to 5. Higher score indicates higher rehabilitation motivation level for all items, except three reverse evaluation items (items #5, #12, and #23), for which a higher score indicates lower motivation level.
Intrinsic motivation inventorybaseline, 2 weeks after baseline, 4 weeks after baseline, 8 weeks after baselineThe Intrinsic Motivation Inventory assesses participants' interest/enjoyment, perceived competence, effort, value/usefulness, felt pressure and tension, and perceived choice while performing a given activity, thus yielding six subscale scores. A higher score will indicate more of the concept described in the subscale name.
Motor evoked potentialbaseline, 2 weeks after baseline, 4 weeks after baseline, 8 weeks after baselineaction potential elicited by noninvasive stimulation of the motor cortex through the scalp
Modified Ashworth scalebaseline, 2 weeks after baseline, 4 weeks after baseline, 8 weeks after baselineModified Ashworth scale measures resistance during passive soft-tissue stretching. Scores range from 0-4, with 5 choices. A score of 1 indicates no resistance, and 5 indicates rigidity.
