Enhancing Exercise and Psychotherapy to Treat Pain and Addiction in Adults With an Opioid Use Disorder (EXPO; R33 Phase) (EXPO-R33)

March 20, 2026 updated by: Nora Nock, Case Western Reserve University

Enhancing Exercise and Psychotherapy to Treat Pain and Addiction in Adults With an Opioid Use Disorder (EXPO): A Randomized Trial (R33 Phase)

This work will involve conducting a randomized trial that will evaluate preliminary efficacy of "assisted" rate cycling, voluntary rate cycling and psychotherapy for pain individually and in combination as adjunctive treatments on cravings (primary outcome) in adults with an opioid use disorder. The investigators will also evaluate the effects of "assisted" rate cycling, voluntary rate cycling and I-STOP on secondary outcomes including depression, anxiety and sleep.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Assisted Exercise and I-STOP
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). 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).
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").
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".
Experimental: Voluntary Exercise and I-STOP
Participants randomized to "Voluntary Exercise" will exercise on a standard stationary bike where they will pedal at their voluntary rates. 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).

Experimental: Assisted Exercise and No I-STOP
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). Participants randomized to "No I-STOP" will not receive the psychotherapy for pain and addiction but will receive their standard behavioral treatment as usual (TAU).

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").
Experimental: No Exercise and I-STOP
Participants randomized to receive "No Exercise" will not receive structured "assisted" or voluntary rate cycling exercise. Participants randomized to "No I-STOP" will not receive the psychotherapy for pain and addiction but will receive their standard behavioral treatment as usual (TAU).
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".
No Intervention: No Exercise and No I-STOP
Participants randomized to receive "No Exercise" will not receive structured "assisted" or voluntary rate cycling exercise. Participants randomized to "No I-STOP" will not receive the psychotherapy for pain and addiction but will receive their standard behavioral treatment as usual (TAU).
