- Brief Summary
The purpose of this research is to test the feasibility of an intervention using biofeedback to treat stress and anxiety among individuals with tetraplegia.
The expected duration of participation in this study is about 5 hours over the course of about 5 weeks. Participants will be randomly assigned to either a biofeedback training intervention or a control group. After completing questionnaires, participants will undergo physiological monitoring for the purpose of measuring heart rate and breathing. Those assigned to the biofeedback group will undergo 20 minutes of physiological monitoring while also participating in biofeedback training twice a week for 4 weeks (8 sessions) from home. Those assigned to the control group will undergo 20 minutes of physiological monitoring twice a week for 4 weeks (8 sessions) from home, but will not receive biofeedback training. Each session is expected to last 30 minutes to allow for completion of questionnaires over the the phone prior to and following each training session.
It is hypothesized that the biofeedback intervention will demonstrate high feasibility and compared to those in the control group, participants who receive the biofeedback intervention will attain greater pre-post reductions in both physiological and self-reported stress.

Group Intervention Description Biofeedback Psychophysiological monitoring Participants (n=15) will undergo 30 minutes of self-administered 1-channel (ECG) physiological monitoring at home using the Mindfield eSense Pulse twice a week for four weeks (eight sessions in total). The biofeedback training session will be conducted using the eSense Pulse smartphone application. Participants will receive further instruction explaining how physiological information will be displayed and used as a means of training to induce a relaxed state while receiving real time feedback. Participants will be instructed on using controlled breathing to assist with reaching this relaxed state. Prior to each training session, the Study Coordinator will meet with the participant via Zoom to virtually assist with setup. Following each training session, participants will respond to questionnaires over the phone.

Control Group Psychophysiological monitoring Participants (n=15) will undergo 30 minutes of self-administered 1-channel (ECG) physiological monitoring at home using the Mindfield eSense Pulse twice a week for four weeks (eight sessions in total). Participants will be provided with the following instructions: "You will be monitored with this equipment for 30 minutes. During this time frame, please try to limit movement and conversation as much as possible." Prior to each training session, the Study Coordinator will meet with the participant via Zoom to virtually assist with setup. Following each training session, participants will respond to questionnaires over the phone.
- Primary Outcome Measures
Name Time Method Change in physiological stress Session #1 (week 1) and Session #8 (week 4) Average LF (ms2)
Change in Depression Anxiety Stress Scale-21 (DASS-21) scores Baseline (week 0) and Session #8 (week 4) The Depression Anxiety Stress Scale-21 (DASS-21) is a self report instrument designed to measure core symptoms of depression, anxiety, and stress. Each of the three DASS-21 scales contains seven items, divided into subscales with similar content. Scores for depression, anxiety, and stress are calculated by summing the scores for the relevant items. Items are rated on a scale from 0 (did not apply to me at all) to 3 (applied to me very much or most of time), with higher scores indicating more depression, anxiety, and stress.
Change in Subjective Units of Distress Scale (SUDS) scores Baseline (week 0) and Session #8 (week 4) The Subjective Units of Distress Scale (SUDS) is a single-item self report instrument designed to measure the intensity of feelings and other internal experiences such as anxiety, anger, agitation, stress, or other painful feelings. A scale of 0 to 100 will be used to measure the subjective intensity of disturbance or distress experienced by the participant. A higher score indicates greater distress.
- Secondary Outcome Measures
Name Time Method State Trait Anxiety Inventory (STAI) After intervention sessions #1-8 (weeks 1 through 4) The State Trait Anxiety Inventory (STAI) is a 40 item self-report inventory consisting of 20 items to assess trait anxiety and 20 items to assess state anxiety. Items are rated on a scale from 1 (not at all) to 4 (very much). A total score is calculated by summing all six scores, multiplying the sum by 20, and then dividing by six. Total scores range from 20 - 80 with higher scores indicating greater self-reported anxiety. A normal score on the STAI is 34 - 36.
Symptom list After intervention session #1 (week 1), before and after intervention sessions #2-8 (weeks 1 through 4) A list of self-reported symptoms will be used to track any new symptoms requiring medical attention that emerge during the course of the study.
