BFT-Brain Function Therapy is one of the earliest computer based cognitive retraining programs developed for use with brain damaged patients.
Scientific papers on BFT have been also presented in many clinical conferences. The program is used in several clinical centers in India.
BFT is a highly professional program for improving speed and accuracy of neurocognitive processes and measures the improvements in speed in terms of millisecond.
Similarly complexity-difficulty levels can be changed stepwise for gradual retraining or restoration.When the program is used for clinical purposes,i.e. with brain damaged patients, or children with cognitive difficulties, it must be administered by an expert technician, until the client learns to perform the tasks by himself.
1. Number recognition: Increasing number of digits, speed of recognition, recognition and recall from memory.
2. Character (Alphabet) recognition: Increasing number of alphabets, speed of recognition, recognition and recall from memory.
3. Word recognition: direct comparison and comparison from memory. Recognition of word array, shifting fixation points and reading. Recognition and comparison of visual imageries of words.
4. Reading: Reading words and sentences, speed of reading, immediate and delayed recall, reading and comprehension.
5. Visuospatial Comparison: Direct comparison of geometric forms, and comparison from memory. Speed of recognition, and delayed recognition.
6. Working Memory Tasks
i) Using Numbers: Direct comparison and from memory: Recognize the number that flashes in the centre of the screen and identify the numbers that come before and after the recognized number.
ii) Spatial: Comparison and recognition of the appeared geometric shape from an array of shapes that appears. Recognizing if the shape appears on the right end or the left end of the array or if the shape doesn’t appear in the array. Relevant responses using the keyboard are to be made.
7. Temporal Sequencing: Recognize temporal sequence of numbers, hold and detect the same sequence.
8. Continuous Performance test: This is a typical ‘n’ back test, in which there is a continuous presentation of different geometric figures one after the other in which a figure may occasionally repeat itself, when the subject makes response using the keyboard. The intertrial interval can be arranged to randomly vary around a preset value. The repetition of the figure is randomly arranged and the random order and the figure details are set in a data file.
9. Response Inhibition. Adapted from “Go – no Go” paradigm. 4 levels of performance.
10. Alphanumeric Sequencing: Series of 1 to 4 (as selected by the user) alphabets or numbers will be presented. The series should either be arranged in Ascending order or Descending order (as chosen by the user).
