Clinical Trial Summary

This joint research project between the Department of Veterans Affairs (VA) and Department of Defense (DoD) will demonstrate that the implementation of the Mobile Device Outcomes-based Rehabilitation Program (MDORP) will improve the quality of rehabilitative care at a decreased cost to the healthcare system and a reduced burden for service members (SMs) and veterans with lower limb loss. The development of the MDORP will be executed by a multisite translational clinical care team that will use web-based mobile computing devices designed to assess mobility, enable remote prescription of targeted exercise program, and provide continual measureable outcomes to document the continuum of care with the intent of maximizing prosthetic performance while minimizing adverse medical events. The information obtained from this web-based mobile device application will be used by clinicians to promote continuity of care from the DoD and VA facilities nationwide to the community and at home.

Intervention

Device:
• Rehabilitative Lower-limb Orthopedic Accommodating-feedback Device (ReLOAD)
The study will use a novel piece of technology, the ReLOAD, which is a data collector system that uses instrumented insoles, custom, miniature (1"x1") microcontroller with accelerometer, gyroscopes, and geomagnetic sensors connected to a Bluetooth transceiver to collect and transmit gait kinematic data to mobile devices, such as an iPad and iPod. When a person walks or performs a specific activity, the ReLOAD system captures the movement, which can then be stored locally within the mobile device and/or encrypted and sent to a secured central server. This allows the patient or provider to access clinically relevant biomechanical data to help guide rehabilitation.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Timed Up and Go (TUG)	The TUG is a measure of basic mobility that assesses the time to complete a sit to stand activity from a standard height chair, ambulate less than 10 feet, perform a turning activity, ambulate back to the chair and perform stand to sit activity. It is a measure of mobility and predictor of falls risk.	Baseline; Weeks 2,4,6 and 8; Month 3 Follow-Up
Primary	Change in Six-minute Walk Test (6MWT)	The 6MWT has been found to be a measure of overall mobility and physical functioning in the lower limb amputee population and geriatric population. It will be used to provide an overall measure of mobility and musculoskeletal endurance.	Baseline; Weeks 2,4,6 and 8; Month 3 Follow-Up
Primary	Change in Amputee Mobility Predictor (AMP)	The AMP is a 21 item clinical tool that assesses current functional capability and mobility with a prosthesis when performing basic daily activities. The AMP assesses the ability of an amputee to complete 20 different items that progress in level of difficulty. Higher AMP scores indicate greater prosthetic ambulation capabilities.	Baseline; Weeks 2,4,6 and 8; Month 3 Follow-Up
Primary	Change in Bilateral-Amputee Mobility Predictor (BAMP)	The BAMP is the AMP adapted for those with bilateral lower limb loss.	Baseline; Weeks 2,4,6 and 8; Month 3 Follow-Up
Primary	Change in Comprehensive High-level Activity Mobility Predictor (CHAMP)	The CHAMP is a clinical tool that assesses an individual's capabilities in performing high-level mobility and agility activities in multiple planes of motion. It consists of four tests (Single Limb Stance, Edgren Side Step Test, T-Test, and Illinois Agility Test) and generates a total score that indicates greater high-level mobility capabilities.	Baseline; Weeks 2,4,6 and 8; Month 3 Follow-Up
Primary	Change in Symmetry of External Work (SEW)	The SEW is a biomechanical outcome measure for assessing dynamic movement symmetry during functional activities. SEW values represent the effort undertaken by each lower-limb in moving the body forward during walking. It will be assessed simultaneously with the TUG, AMP, 6MWT, and CHAMP.	Baseline; Weeks 2,4,6 and 8; Month 3 Follow-Up
Primary	Change in Modified Test of Sensory Integration and Balance (mCTSIB)	The mCTSIB is a test to describe postural control under various sensory conditions. The test requires subjects to maintain balance for 30 seconds in four conditions: firm surface with eyes open, firm surface with eyes closed, standing on foam with eyes open, and standing on foam with eyes closed.	Baseline; Weeks 2,4,6 and 8; Month 3 Follow-Up
Secondary	Charleson Co-Morbidity Index	Description of Current Medical Conditions	Baseline; Weeks 2,4,6 and 8; Month 3 Follow-Up
Secondary	Bandura's Self-efficacy Survey	Self-motivation for exercise	Baseline; Weeks 2,4,6 and 8; Month 3 Follow-Up
Secondary	New Injury Severity Score	History of the musculoskeletal injuries due to the participant's traumatic event will be documented using self-report and past and current medical records from each participant. The injuries will be categorized into anatomical body regions using the Abbreviated Injury Scale (AIS). The New Injury Severity Score (NISS) will be calculated using the AIS for each participant to determine injury severity.	Baseline; Weeks 2,4,6 and 8; Month 3 Follow-Up
Secondary	Patient Reported Outcome Measure Information System (PROMIS)	Physical Function domains will be used to describe the participant's performance of standard activities of daily living, pain intensity, pain severity, fatigue with activities, and sleep disturbance. The PROMIS Mental Health domains will be used to describe the participant's current state of depression, anger, and anxiety with daily activities.	Baseline; Weeks 2,4,6 and 8; Month 3 Follow-Up
Secondary	International Physical Activity Questionnaire (IPAQ)	Physical Activity Questionnaire	Baseline; Weeks 2,4,6 and 8; Month 3 Follow-Up
Secondary	Trinity Amputation and Prosthesis Experience Scale-Revised (TAPES-R)	The TAPES will be administered to the participants with lower limb loss in order to assess psychosocial adjustment, activity restriction, and satisfaction with their current prosthesis. It contains 33 self-reported items; psychosocial adjustment, 15 items; activity restriction, 10 items; and satisfaction, 8 items.	Baseline; Weeks 2,4,6 and 8; Month 3 Follow-Up
Secondary	Prosthetic Limb Users Survey- Mobility (PLUS-M)	The PLUS-M is a self-report measure of mobility designed for prosthetic limb users to assess mobility performing different activities of daily living within the home and community.	Baseline; Weeks 2,4,6 and 8; Month 3 Follow-Up
Secondary	Socket Fit Comfort Scale	Socket comfort and fit assessment.	Baseline; Weeks 2,4,6 and 8; Month 3 Follow-Up
Secondary	Activities-specific balance confidence scale (ABC)	Measurement of balance confidence.	Baseline; Weeks 2,4,6 and 8; Month 3 Follow-Up
Secondary	Modified Oswestry Low Back Pain Disability Index (MODI)	The MODI is a 10-item questionnaire that will be used to assess current presence and severity of low back pain with different daily activities.	Baseline; Weeks 2,4,6 and 8; Month 3 Follow-Up
Secondary	Lower Extremity Functional Scale (LEFS)	The LEFS is a 20- item questionnaire that assesses one's ability to perform activities of daily life, functional mobility, balance, coordination, and range of motion/strength. It is scored on a 4 point scale for each question for a maximum score of 80.	Baseline; Weeks 2,4,6 and 8; Month 3 Follow-Up
