Develop a game-based upper-extremity motor and cognitive rehabilitation system using custom and adaptable virtual reality simulations. Perform usability study on 2 elderly healthy volunteers and 2 breast cancer survivors with lasting cognitive impairments following chemotherapy, so to improve the product design. The usability evaluation will be done at NJ Bioscience Center (North Brunswick, NJ).
The study will generate data on ease of use of a system for subjects with stage II or stage III breast cancer survivors with lasting cognitive impairments subsequent to their first chemotherapy regimen. The usability component will uncover technical issues in its usability, as well as its rating on perceived usefulness. Data will also be collected on the ease of remote monitoring of the subjects by clinicians. This portion of the study is intended to provide information pertaining to the usability of the experimental system for remote integrative (cognitive and motor) therapy of breast cancer survivors (Stage II or III) with lasting chemotherapy related cognitive impairment (CRCI) subsequent to first chemotherapy regimen, living in the community. Specific aims are: 1. testing of a added biosensors, new technology acceptance and ease of use at home by these individuals; 2. a caregiver console and enhanced automatic session report that will allow remote monitoring of patient exercising and offline data processing and review. Participants will each perform 4 usability evaluation sessions. At the end of each session participants will fill a custom evaluation form, using 5-point Likert scale scoring. At the end of the last session participants will also fill a USE standardized usability evaluation form.
Study Type
OBSERVATIONAL
Enrollment
4
Participants will first be screened for propensity to simulation sickness and for cognitive state using the MoCA evaluation test. Those who passed the screening will perform 4 usability sessions rating the ease of use and perceived benefit of the experimental system and of a caregiver interface laptop. The 2 healthy volunteers will evaluate first, such that issues may be resolved before testing is done on the impaired participants. Each session will be compensated with a $35 payment. During each session participants will play a series of increasing difficulty simulated tasks, aimed to train primarily the executive functions domain. At the end of each session participants will rate their experience using custom subjective evaluation forms with multiple items. Each item will be scored using a 5-point Likert scale. At the end of the 4th session, participants will also fill the USE standardized usability form. This usability evaluation will be conducted at the NJ Bioscience Center.

USE questionnaire to assess the usability of a computerized system
A standardized questionnaire to assess the usefulness, satisfaction and ease of use of the experimental system \[Lund, 2001\] when evaluated by study participants. The form consists of 30 questions, each rated on a 7-point Likert scale (1 worst 7 best). The score range for this form is 30 (min) to 210 (max). Participants will also be able to comment in free form on aspects they liked most and least about the device.
Time frame: At the end of the 4th evaluation session (about 1 month from enrollment)
Subjective rating questionnaire of the device and therapy
Participants rate the usefulness, satisfaction issues, and ease of use of the experimental system and its therapeutic games, as well as ease of use of the Caregiver laptop. The Subjective Evaluation Form consists of questions, each rated on a 5-point Likert scale (1 worst to 5 best outcome).
Time frame: At each of 4 evaluation sessions over 1 month from enrollment
