Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Stage-I: Self Monitoring Exercise Using a Health App
Participants will be randomized into one of two groups: Group 1 (self monitoring using a non-interactive app), and Group 2 (self monitoring using an interactive app). Participants in both groups will be provided a customized exercise program to complete over the duration of the study. Within either app, participants will be able to view assigned exercises, log additional exercises completed, complete questionnaires as needed, and access additional resources. Participants will use their own smartphone to receive the health app. Participants will continue using their Stage-I app intervention for the entire duration of the study (weeks 1-24).
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: Strategy to Address Non-Adherence
After 12 weeks, the participants will be categorized as adherents or non-adherents based on their rates of adhering to the SCI exercise guidelines during Stage-I. Non-adherents (those who met the exercise guidelines \<50% of the weeks) will be randomized to receive an augmented intervention of motivational interviewing-based e-coaching (2x per month or 4x per month) in addition to their Stage-I assigned app for 12 weeks (weeks 13-24) to further increase rates of exercise. All non-adherents who will be assigned to the e-coaching interventions will be asked to complete at least daily EMA surveys. A coach who is trained in motivational interviewing will review the EMA data and work collaboratively with participants to identify barriers and facilitators and develop individualized strategies to improve exercise adherence. Adherents (those who met the exercise guidelines \>50% of the weeks) will continue with only their Stage-I assigned app intervention throughout Stage-II.
Stage-II, Groups 1a/2a: E-Coaching 1x 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 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 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).
