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.

Spinal Cord Injuries; Anxiety; Stress; Tetraplegia

Outcome Measures

Primary Outcomes (3)

• Change in physiological stress

  Average LF (ms2)

  Session #1 (week 1) and Session #8 (week 4)

• Change in Depression Anxiety Stress Scale-21 (DASS-21) scores

  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.

  Baseline (week 0) and Session #8 (week 4)

• Change in Subjective Units of Distress Scale (SUDS) scores

  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.

  Baseline (week 0) and Session #8 (week 4)

Secondary Outcomes (2)

• Symptom list

  After intervention session #1 (week 1), before and after intervention sessions #2-8 (weeks 1 through 4)

• State Trait Anxiety Inventory (STAI)

  After intervention sessions #1-8 (weeks 1 through 4)

Other Outcomes (4)

• Brief Pain Inventory (BPI) - 4 pain severity items

  Baseline (week 0) and Session #8 (week 4)

• Brief Pain Inventory (BPI) - current pain severity item

  Before and after intervention Sessions #1-7 (weeks 1 - 3)

• Brief Pain Inventory (BPI) - pain relief item

  After each intervention Session #1-8 (weeks 1 - 4)

Study Arms (2)

Biofeedback

EXPERIMENTAL

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.

Behavioral: Psychophysiological monitoring; Behavioral: Biofeedback training

Control Group

ACTIVE COMPARATOR

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.

Behavioral: Psychophysiological monitoring

Interventions

Psychophysiological monitoring BEHAVIORAL

30 minutes of one channel (ECG) physiological monitoring with Mindfield eSense Pulse.

Biofeedback; Control Group

Biofeedback training BEHAVIORAL

Traditional resonance frequency training with the Mindfield eSense Pulse smartphone application. Using visual feedback of real time parameters of HRV and the use of controlled breathing, participants are trained to reach a relaxed state.
