Neural Impairment Test Suite

Neural impairment test suite is a tool to evaluate health state for patients, suffering from Huntington disease (HD), Parkinson disease (PD) or Alzheimer's disease (AD) in early stages.
Symptoms of the patient are evaluated by conducting simple tasks for detection of tremor, cognitive, speech and energy expenditure impairments.

Tremor impairment tasks:

• T1: Sequential Touch. Patient is instructed to touch one-coloured circular objects located in device screen sequentially from first till last with 1 finger. Goal is to touch as close to centre and as fast as possible.
• T2: Rainbow Color Touch. Patient is instructed to touch indicated color (from rainbow spectrum) circular object using 1 finger as close to centre and as fast as possible.
• T3: Multi-Touch. Patient is instructed to touch shown number of circles using multiple fingers (one or both hands). 3 modes are supported: 2 circles, 3 and 6 circles. Goal is to touch as close to centre and as fast as possible.
• T4: Archimedean Spiral. 2 modes are supported. In 1-st mode patient is instructed to follow Archimedean spiral contour using his finger clockwise. In 2-nd mode, patient is asked to draw spiral contour himself counter clockwise. Goal is to follow (draw) spiral contour as precise as possible.

Cognitive impairment tasks (based on SAGE methodology,

• T5: General Questions (Insights). Patient is surveyed about his memory (thinking), balance, depression problems etc.
• T6: Orientation (Current Day). Patient is asked to memorize and enter current date (year, month, day).
• T7: Picture Naming. Patient is instructed to recognize shown picture and write down name of the picture in device screen.
• T8: Similarities, Calculation. Patient is instructed to answer given questions, which require basic mathematical knowledge.
• T9: Construction (3D figure). Patient is instructed to draw (replicate) given 3D shape e.g. cube.
• T10: Construction (Clock). Patient is instructed to draw a large face of a clock, place in the numbers, position the hands for given time in hours and minutes.
• T11: Verbal Fluency. Patient is asked to enter a specified number of names in a category e.g. countries.
• T12: Executive (Modified Trials). Patient is instructed to draw a line from one circle to another starting at 1 and alternating numbers and letters.
• T13: Executive (Problem Solving). Patient is instructed to place lines to form logical shape e.g. 2 squares.
• T0: Memory. Patient is instructed to remember a sentence and enter it at the end of testing (only supported in integration mode)

Speech impairment tasks:

• T14: Voice Recorder. Patient is instructed to repeat shown text paragraph (e.g. poem) using his voice for several times.

Energy Expenditure impairment asks:

• T15: TDEE. Total daily energy expenditure (TDEE) metric is calculated after patient is surveyed
about his daily food ration and exercise activities.

Extra features:
• Training mode: patient can try out individual tasks for multiple times before actual testing procedure
• Testing mode: proposed 16 tasks are sequentially integrated by providing each next test randomly, thus not allowing patients to cheat and memorize tasks
• Integration of all 4 different test forms, as officially provided by SAGE methodology
• Multi-Language (English and Lithuanian) support
• Automatic collection of data and features from tasks
• Automatic evaluation of patient health state after test procedure
• Synchronization with researcher's Google drive account
• Customizable GUI component (Button, TextView, ImageView) size for improved usage convenience to patients with neurological disorders
• Locking the app screen to prevent unnecessary redrawing of shapes when particular test mode is activated
• Anonymous testing
