Study: NCT04736550

Intervention type: BEHAVIORAL
Group type: EXPERIMENTAL
Intervention: Exercise
Description: Participants who are randomized to exercise will be perform exercise on stationary bikes. Participants randomized to Voluntary Exercise will exercise on a standard stationary bike where they will pedal at their voluntary rates. Participants randomized to Assisted Exercise will exercise on a special bike that assists them to pedal faster than they do voluntarily on their own (assisted (exercise) bike).

Intervention: Psychotherapy for Pain (I-STOP)
Description: Participants who are randomized to receive I-STOP will receive the Self-regulation Treatment for Opioid addiction and Pain (STOP) program modified for inpatients/residential drug treatment (I-STOP). I-STOP uses empirically validated pain psychotherapy approaches targeted to patients with an OUD using psycho-physiological self-regulation components and biofeedback with Bio-dots.
