Other	Modified Falls Efficacy Scale (mFES)	The mFES is self-report questionnaire consisting of 14 items which is designed to measure fear of falling in the elderly. It assesses an individual's perception of balance during activities of daily living by asking "how confident are you that you can do the following activities without falling."	Change from baseline in score after using device at 3, 6, and 12 month follow-up.
Other	Spinal Cord Injury Quality of Life (SCI-QOL)	The SCI-QOL are a battery of self-reported questionnaires completed by participants to evaluate perceptions of personal independence, ability to communicate needs with others, and sense of control over one's life in individuals with spinal cord injury.	Change from baseline in score after using device at 3, 6, and 12 month follow-up.
Other	EQ5D-5L	A self-reported, health related, quality of life questionnaire. It measures quality of life in 5-components including mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each level is rated on a scale describing the degree of problems in that area. It ends with an overall health scale between 1-100 to rate the level of health the user is experiencing at the time of the test.	Change from baseline in score after using device at 3, 6, and 12 month follow-up.
Other	Orthotics and Prosthetics User Survey (OPUS)	The Orthotic and prosthetics User Survey is a self-report questionnaire which is designed to evaluate the outcome of orthotic and prosthetic services. We will administer three of the five domains: lower limb functional measure, health-related quality of life, and satisfaction with device. The domains of upper limb functional measure and satisfaction with service are not applicable in this study.	Change from baseline in score after using device at 3, 6, and 12 month follow-up.
Other	World Health Organization Quality of Life (WHOQOL-BREF)	The WHOQOL-BREF is a self-report questionnaire that measures an individual's perceived quality of life. It contains four domains which cover physical health, psychological health, social relationships, and environment. Scores range from 0-100 with 100 indicating a higher quality of life. The scores can be broken down by domain or taken as a whole. The WHOQOL-BREF is valid cross-culturally.	Change from baseline in score after using device at 3, 6, and 12 month follow-up.
Other	International Spinal Cord Injury Bowel Function Data Set	The purpose of this test is to standardize collection and reporting on the bowel in individuals with spinal cord injury. Questions include bowel care procedures, surgical procedures, time, frequency, and method of bowel practices.	Change from baseline in score after using device at 3, 6, and 12 month follow-up.
Other	International Spinal Cord Injury Lower urinary Tract Basic Data Set	The purpose of this test is to standardize collection and reporting of information on the lower urinary tract in individuals with spinal cord injury. Questions include surgical procedures, drugs, bladder emptying, and incontinence. These are used by clinicians and researchers so that data can be shared and combined easily.
