Clinical Trial Summary

The goal of this research is to increase physical activity among individuals with a spinal cord injury (SCI) through a customized, interactive smartphone-based health app and e-coaching using three phases: (1) leading focus groups of potential app users and clinicians to gain information regarding health apps preferences for optimal consumer use, (2) conducting a usability study of the customized app to determine the quality and implement further changes for optimization, and (3) conducting a sequential multiple assignment randomized trial (SMART) to determine the most effective adaptive intervention to improve exercise adherence. A SMART trial will be used to determine when and how to adapt dosage, timing, and delivery to increase adherence and address low-response behaviors. In Stage-I, the investigators will compare outcomes among participants using a generic, non-interactive exercise app (Group 1) to a customized, interactive app that can gain information through frequent Ecological Momentary Assessments (EMA) that will be used to modify each participant's exercise programs (Group 2). After 12 weeks, participants who are not meeting the exercise guidelines at least 50% of the time will also be asked to participate in motivational interviewing-based e-coaching either two or four times per month in addition to their originally assigned intervention (Stage-II). By completing these three phases, this project addresses deficiencies in exercise levels and compliance by implementing an individualized exercise prescription, an adaptive intervention for low responders, a way to address barriers to exercise, and a free smartphone app for broad implementation.

Description:

This study will investigate the effect of a low-cost, multi-component, individualized, and adaptive telehealth program on (1) adherence to exercise guidelines by community-dwelling adults with spinal cord injury (SCI) and (2) on improving health and functional outcomes categorized by the World Health Organization's International Classification of Functioning, Disability and Health (ICF) model. The proposed trial consists of three phases: Phase 1: Technology Development (not a clinical trial) Participants with SCI, caregivers, and clinicians Aim 1: Obtain input from consumers on the modifications needed to customize smartphone-based apps to assess and facilitate exercise adherence. With input from consumers and clinicians during in-person and remote focus groups, the investigators will gain information that can be used to develop and modify exercise and health monitoring apps to optimize usability and compliance. The investigators will ask a group of "expert" clinicians and researchers that are knowledgeable about SCI to identify the most important constructs to discuss during the focus groups. The focus groups will include various app stakeholders (individuals with SCI, caregivers, clinicians) to ensure diverse perspectives from all potential app users. --- Phase 2: Usability Testing (not a clinical trial) Participants with SCI only Aim 2: Conduct a usability study of custom apps to optimize their acceptability, appropriateness, and feasibility. The investigators will assess the acceptability, appropriateness, and feasibility of the customized exercise app in persons with SCI, and determine the quality (i.e., engagement, functionality, aesthetics, information quality, and perceived benefits) of these apps. From usability metrics collected after participants with SCI completed a two-week trial using the app, the investigators can implement further changes to further optimize the app. --- Phase 3: Two-Stage SMART Trial (clinical trial) Participants with SCI only Aim 3: Conduct a proof-of-concept sequential multiple assignment randomized trial (SMART) study to determine the most effective adaptive interventions to improve exercise adherence and health and functional outcomes. In Stage-I, the investigators will compare the effect of using (Group 1) commercially available, free to use, non-interactive smartphone health apps (a simplified version of Pt Pal) vs. (Group 2) a personalized, interactive app (Pt Pal), which allows for customizations for each individual. While both groups will be provided customized exercises at the beginning of the intervention, only those in Group 2 will get regular (i.e., bi-weekly/monthly) exercise updates based on their progress and Ecological Momentary Assessments (EMA) monitoring throughout Stage-I (weeks 1-12). In Stage-II (weeks 13-24), e-coaching will be added for participants who do not achieve at least 50% guideline adherence using these app-based interventions in Stage-I. The investigators will randomize participants who are not adherent to the exercise guidelines to either twice per month (Groups 1a/2a) or four times per month (Groups 1b/2b) e-coaching that utilizes SCI-specific EMA and motivational interviewing techniques. E-coaching in real-time using trained personnel will augment the initial intervention to support coping with barriers and action planning. Outcomes will be reassessed at the end of Stage-I (12 weeks) and Stage-II (24 weeks). Aim 3.1: Compare effects of two app-based interventions on primary and secondary outcomes: Group 1 (customized exercise + non-interactive app) vs. Group 2 (customized exercise + interactive, customized app). Aim 3.2: Compare effects of two augmented interventions on primary and secondary outcomes: Groups 1a and 2a (e-coaching twice per month) vs. Groups 1b and 2b (e-coaching four times per month). --- Exploratory Phase: (not a clinical trial) Participants with SCI, caregivers, and clinicians Exploratory Aim: Explore exercise protocols, questionnaire delivery, sensor types/setups, sensor parameters, and/or analysis techniques to optimally capture psychosocial, mobility, and other characteristics. As needed, the investigators may trial variations of the questionnaires, sensors, and other parameters using to optimize the data collection procedures for Phases 1-3.

Intervention

Behavioral:
• Stage-I, Group 1: Self monitoring using Non-interactive App
Participants in Group 1 will have minimal features that affect compliance (notifications, rewards, EMA, etc.) and no modifications to their exercise program after initial prescription.
• Stage-I, Group 2: Self monitoring using Interactive App
Participants in Group 2 will use the version of the exercise app that has been modified based on the findings from Phases 1 and 2 of this study. Group 2 will be able to use the full features of the interactive app including notifications, ability to submit videos, and non-synchronous messaging/communicating with the researcher. Additionally, participants in Group 2 will be asked to complete 2-5 EMA-based surveys daily to gain information about the participant's barriers and facilitators to exercise. The information from the EMA questionnaires will be used to progress and modify the exercise program at regular intervals for each participant in Group 2.
• Stage-II, Groups 1a/2a: E-Coaching 2x per month
In addition to the Stage-I assigned app, participants will be asked to complete at least daily EMA questionnaires and e-coaching sessions two times a month throughout Stage-II (weeks 13-24). Participants will only receive the augmented e-coaching intervention if they were not adherent to the exercise guidelines for at least 50% of the weeks during Stage-I (weeks 1-12).
• Stage-II, Groups 1b/2b: E-Coaching 4x per month
In addition to the Stage-I assigned app, participants will be asked to complete at least daily EMA questionnaires and e-coaching sessions four times a month throughout Stage-II (weeks 13-24). Participants will only receive the augmented e-coaching intervention if they were not adherent to the exercise guidelines for at least 50% of the weeks during Stage-I (weeks 1-12).

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Change in 10 Meter Walk or Wheelchair Propulsion Test from Baseline to 12 Weeks	The 10-Meter Walk Test (10-MWT) assesses subject walking speed in meters per second for 10 meters. Subjects may repeat each measure up to 3 times at their normal self-selected walking speed and 3 times at a fast speed while still able to maintain safety. If the participant primarily uses a manual wheelchair, the Wheelchair Propulsion Test (WPT) will instead be administered. The WPT assesses subject push speed, push frequency, and push effectiveness for 10 meters. Subjects will propel using their usual method and may complete up to 3 trials. For either assessment, a higher change in speed would indicate faster ambulation/wheelchair propulsion (better outcome) at the later time point than the earlier time point.	From Baseline to 12 weeks

Other	Change in Barriers to Physical Activity Questionnaire for People with Mobility Impairments from Baseline to 12 Weeks	The Barriers to Physical Activity Questionnaire for People with Mobility Impairments (BPAQ-MI) is a self-reported 43-item questionnaire to identify the perceived barriers and the extent of barriers to physical activity experienced by people with mobility impairments. Items are weighted, so minimum and maximum values for each domain vary. A higher score is always indicative of more problematic barriers and a decrease in BPAQ-MI scores at the later time point (compared to the earlier time point) would be indicative of less problematic barriers and a better outcome.

Primary	Rate of Adherence to SCI exercise guidelines	Using app-based data and self-report, the investigators will determine if each participant met the SCI aerobic exercise guidelines (moderate to vigorous aerobic exercise for at least 20 minutes twice per week) for each week of the study. The investigators will total the number of weeks in which the participants achieved adherence and calculate the percentage of adherence over each 12-week stage. An overall adherence rate of 50% will be regarded as meeting exercise guidelines for the stage.	12 weeks

Secondary	Change in Six-Minute Walk/Push Test from Baseline to 12 weeks	The Six-minute Walk (6MWT) and Six-minute Push (6MPT) Tests measure the distance a subject can cover while indoors on a flat, hard surface in a period of 6 minutes. The investigators will determine which test is most appropriate to administer based on the participant's primary mode of mobility (ambulation= 6MWT, manual wheelchair=6MPT). These tests will be used to determine each participant's change in endurance capacity with a greater increase in distance at the later time indicating greater improvements in endurance.

Secondary	Change in Exercise Self-Efficacy from Baseline to 12 weeks	The Exercise Self-Efficacy Scale assesses an individual's beliefs in their ability to continue exercising on a three time per week basis at moderate intensities for 40+ minutes per session in the future. Participants will indicate their confidence for each domain on a 100-point percentage scale comprised of 10-point increments, ranging from 0% (not at all confident) to 100% (highly confident). Exercise Self-Efficacy scale will be modified to match the SCI exercise guidelines of exercising on a two time per week basis at moderate intensities of aerobic exercise for 20+ minutes per session and/or prescribed strength training. A greater increase in score at the later time point is indicative of greater improvements in self-efficacy (better outcome).	From Baseline to 12 weeks

Secondary	Change in Spinal Cord Injury-Quality of Life Scales from Baseline to 12 Weeks	The Spinal Cord Injury-Quality of Life (SCI-QOL) are a battery of self-reported questionnaires completed by participants to evaluate perceptions of personal independence, pain interference, depression, mobility, ability to communicate needs with others, sense of control over one's life, or other domains in individuals with spinal cord injury. SCI-QOL scales use a standardized T metric, with a mean of 50 and a standard deviation of 10. Higher change scores on a SCI-QOL item bank represent a greater amount of the construct being measured at the later time point (e.g. better independence, more pain interference compared to the earlier time point).
