The Standing Balance Test is a measure developed to assess static standing balance. It involves the participant assuming and maintaining up to five poses for 50 seconds each. The sequence of poses is: eyes open on a solid surface, eyes closed on a solid surface, eyes open on a foam surface, eyes closed on a foam surface, eyes open in tandem stance on a solid surface. Postural sway is recorded for each pose using an iPod Touch that the participant wears at waist level. The participant's anterior-posterior postural sway information is fed wirelessly to the iPad. A Fully Corrected T-Score is utilized for the interpretation of normative scores that takes into account gender, age, ethnicity and education differences. Fully Corrected T Scores range from 23 - 77 with higher score indicating better balance. Change from baseline to post-test follow-up at 8-weeks is reported.

The Rey is a word-list learning task in which 15 unrelated words are presented orally (via audio recording) over three consecutive learning trials1. After each presentation, the participant is asked to recall as many of the words as he/she can. The Rey is scored by taking the sum of the number of words recalled across all trials (possible range is 0-45 words). The raw score is most commonly used for interpretation of the Rey test, with higher scores representing better episodic memory. Change from baseline to post-test follow-up at 8-weeks is reported.

DCCS is a measure of cognitive flexibility. Two target pictures are presented that vary along two dimensions (e.g., shape and color). Participants are asked to match a series of bivalent test pictures (e.g., yellow balls and blue trucks) to the target pictures, first according to one dimension (e.g., color) and then, after a number of trials, according to the other dimension (e.g., shape). Scoring is based on a combination of accuracy and reaction time. Scores range from 0 - 45. Higher scores indicate higher levels of cognitive flexibility. Change from baseline to post-test follow-up at 8-weeks is reported.

Time frame: Baseline, 8 weeks

The Flanker task measures both a participant's attention and inhibitory control. The test requires the participant to focus on a given stimulus while inhibiting attention to stimuli flanking it. Sometimes the middle stimulus is pointing in the same direction as the flankers (congruent) and sometimes in the opposite direction (incongruent). Scoring is based on a combination of accuracy and reaction time. Scores range from 0 - 45, higher scores indicate higher levels of ability to attend to relevant stimuli and inhibit attention from irrelevant stimuli. Change from baseline to post-test follow-up at 8-weeks is reported.

Time frame: Baseline, 8 weeks

The List Sorting test requires immediate recall and sequencing of different visually and orally presented stimuli (i.e., working memory). Pictures of different foods and animals are displayed with accompanying audio recording and written text (e.g., elephant), and the participant is asked to say the items back in size order from smallest to largest, first within a single dimension (either animals or foods, called 1-List) and then on two dimensions (foods, then animals, called 2-List). List Sorting is scored by summing the total number of items correctly recalled and sequenced on 1-List and 2-List, which can range from 0-26. Higher scores indicate higher levels of working memory. Change from baseline to post-test follow-up at 8-weeks is reported.

In this test, a coding key with nine abstract symbols is presented - each paired with a number between 1 and 9. Participants are asked to orally indicate which numbers go with symbols that are presented on a sheet of paper. The participant is given 120 seconds to call out as many numbers that go with the corresponding symbols as he/she can - without skipping any. The Oral Symbol Digit Test is scored as the number of items answered correctly in 120 seconds (possible range is 0-144), higher scores representing better processing speed. Change from baseline to post-test follow-up at 8-weeks is reported.

Time frame: Baseline, 8 weeks

This test measures speed of processing by asking participants to discern, as quickly as possible, whether two side-by-side pictures are the same or not. The items are presented one pair at a time on the iPad screen, and the participant is given 85 seconds of response time (excluding any time needed for the given iPad to load the items) to respond to as many items as possible. Raw scores range from 0-130, higher scores indicate faster speed of processing. Change from baseline to post-test follow-up at 8-weeks is reported.

The Picture Sequence Memory Test (PSMT) is a measure developed for the assessment of episodic memory. It involves recalling increasingly lengthy series of illustrated objects and activities that are presented in a particular order on the iPad screen, with corresponding audio-recorded phrases played. The participants are asked to recall the sequence of pictures demonstrated over two learning trials. The PSMT is a measure of episodic memory, which involves the acquisition, storage and effortful recall of new information. Age-corrected normative scores are reported on a scale of 59-140 with with higher scores representing better episodic memory. Change from baseline to post-test follow-up at 8-weeks is reported.
