Tango for Neuropathy Among Breast Cancer Survivors

root-mean square of the center of pressure (COP)

Intrinsic motivation will be measured using a subscale of the Intrinsic Motivation Inventory (IMI). The 6 item Interest/Enjoyment subscale of the IMI represents intrinsic motivation in an activity just performed as a possible score of 6 to 36 with 6 = most; 18 = neutral; 36 = least interesting/enjoyable. Specific items queried include whether the activity just performed was: enjoyable, enjoyed, boring (reverse order), interesting, fun, and able to hold the participant's attention.

95% ellipse area of the COP

velocity of COP

sample entropy of the center of pressure (COP). Sample entropy is a non-linear COP measure that determines the irregularity of a time-series. Sample entropy of the resultant COP position will be calculated using the increment calculation method (SEI) with constant values applied of m = 3 and r = 0.3. Entropy of postural responses represents the automatic complexity of neuromotor control that is available to an individual. Sample entropy scores won't go below 0 or above 2, and higher values indicate better complexity in postural response

root-mean square of the center of pressure (COP). The mean will be taken of all beginning of session data points together and all end of session data points together. Lower numbers indicate better neuromotor health.

The Timed Up-and-Go test, or TUG, (<2 min to administer) is a timed test of a person's ability to stand from a chair, walk 10 feet, turn around, and return to sitting with shorter times indicating better functional balance.

European Organization for Research and Treatment of Cancer's Quality of Life Questionnaire, Chemotherapy-Induced Peripheral Neuropathy (CIPN 20): is a validated instrument for longitudinal evaluation of neuropathy symptoms induced by chemotherapy. This is a 20-item patient reported questionnaire. It is easy to use and filled out by patients themselves. Scores range between 1 to 10 with higher scores indicating greater chemotherapy-induced peripheral neuropathy (CIPN) severity. The mean will be taken of all beginning of session data points together and all end of session data points together

The Brief Pain Inventory Short Form (BPI) is a validated instrument used to evaluate pain symptoms and functional capacity "right now" using a single item visual analog scale (VAS) on which participants will rate how much pain they are in "right now" on a scale of 1 to 10 (10 being high the worst pain imaginable). The mean will be taken of all beginning of session data points together and all end of session data points together

The Brief Fatigue Inventory (BFI) is used to rapidly assess the severity and impact of cancer-related fatigue "right now" using a single item visual analog scale (VAS) on which participants will rate how much fatigue they feel "right now" on a scale of 1 to 10 (10 being high the worst fatigue imaginable).

the number of falls or near falls that the participant remembers experiencing in the month prior to enrollment in the study will be assessed. All reported falls will be totaled and reported by arm.

the number of falls or near falls experienced by the participant since last evaluation/intervention session. All reported falls throughout the intervention time period will be totaled and reported by arm.

the number of falls or near falls experienced by the participant in the 6 months post-intervention. All reported falls throughout the follow-up time period will be totaled and reported by arm

Dual task function was measured using the Timed-Up-and-Go motor task while counting backward by 3 s (TUGCog), a validated clinical test of dual-task function for which lower values indicate better performance. To perform this test, participants completed the Timed-Up-and Go (TUG) test commonly used in clinical practice wherein individuals stand from a chair with arms, walk 3 meters, turn around, and return to sitting as fast as safely possible (i.e. motor task) while counting out loud and backward by 3 s (i.e. cognitive task). The test is completed 3 times, with rest allowed between trials. Time in seconds per trial is averaged to produce the TUGCog score per timepoint.

Adherence is measured by the number of enrollees who participated through each time point of the study

The Mini Balance Evaluation System Test short version (MiniBEST): evaluates sensory organization, anticipatory and reactive postural control, and dynamic gait indices on a scale from 1 to 28 points (28 represents the highest function measurable by the test); was recently recommended for use in studies of neuropathy; and discriminated BC survivors from controls in at least 1 prior study. Instrumentation of MiniBEST will enable the calculation of spatiotemporal, kinematic, and co-contraction measures
