Device: ReWalk Rehabilitation 2.0 |
- Change in 6 Minute Walk Test from baseline in distance, RPE and oxygen uptake [ Time Frame: Session 1 (pre test, initial visit) and Session 20 (post test, between 6-8 weeks) ]The goal is to cover as much ground as possible over 6 minutes, the distance is measured with a measuring wheel. The instructions are "Walk continuously if possible, but do not be concerned if you need to slow down or stop to rest." At the end of 6 minutes the participant is asked to rate their exertion level on a Borg Scale of 6 - 20 points. The VO2 MAX data is collected during the test every 10 seconds
- Change in 10 meter walk test from baseline in gait speed [ Time Frame: Session 1 (pre test, initial visit) and Session 20 (post test, between 6-8 weeks) ]Measure the time in second for and individual to walk 10 meters. The test is Performed using a "flying start," patient walks 10 meters (33 ft) and the time is measured when the leading foot crosses the start line and the finish line. The instructions are: " Please walk this distance as fast as you safely can when I say go."
- Time and assistive level to negotiate stairs, ramps, curbs, and turning. [ Time Frame: Session 1 (pre test, initial visit) and Session 20 (post test, between 6-8 weeks) ]
- Distance able to reach while standing and sitting [ Time Frame: Session 1 (pre test, initial visit) and Session 20 (post test, between 6-8 weeks) ]
- Patient perception of Quality of Life [ Time Frame: Session 1 (pre test, initial visit) and Session 20 (post test, between 6-8 weeks) ]
- The Patient Health Questionnaire [ Time Frame: Session 1 (pre test, initial visit) and Session 20 (post test, between 6-8 weeks) ]PHQ-9 is a 9-item self-report questionnaire designed to diagnose both the presence of depressive symptoms as well as to characterize the severity of depression. A single question rates how difficult problems have made it to do work, take care of things at home or get along with other people using a 4 level scale (not difficult at all to extremely difficult).
- The Psychosocial Impact of Assistive Devices Scale [ Time Frame: Session 1 (pre test, initial visit) and Session 20 (post test, between 6-8 weeks) ]The PIADS is a 26-item, self-report questionnaire designed to assess the effects of an assistive device on functional independence, well-being, and quality of life. The PIADS can be used to assess the impact of any assistive device (AD), prosthesis or medical procedure. It can be used to evaluate the impact of ADs over time and to match the devices with consumers. With its excellent psychometric properties, the PIADS fills a missing link in the assessment of ADs as well as in the examination of their acceptance and abandonment.
- Activities-specific Balance Confidence Scale [ Time Frame: Session 1 (pre test, initial visit) and Session 20 (post test, between 6-8 weeks) ]
- Self reported Spinal Cord Independence Measure in activities of daily living [ Time Frame: Session 1 (pre test, initial visit) and Session 20 (post test, between 6-8 weeks) ]
- Pain measure by the Visual Analogue Scale [ Time Frame: Session 1 (pre test, initial visit) and Session 20 (post test, between 6-8 weeks) ]
