# NCT05047120: Hypnotic Cognitive Therapy During Inpatient Rehabilitation to Reduce Acute & Chronic SCI Pain: A Randomized Controlled Trial

Registry record: https://clinicaltrials.gov/study/NCT05047120 (retrieved 2026-09-30). Sponsor: University of Washington.

## What you are forecasting

**Primary hypothesis (implied by design):** Hypnosis-enhanced cognitive therapy (HYP-CT) reduces pain (0-10 NRS) more than spinal cord injury pain education during inpatient rehabilitation.

**Resolution rule:** Supported if the report finds a significant between-arm difference favouring HYP-CT on the first registered primary outcome (0-10 NRS pain decrease following live therapist sessions). If the report instead designates weekly average pain intensity after 4 weeks as its primary, that outcome decides.

**Alpha:** 0.05, two-sided, unless the report states otherwise

**Effect metric for your 90% interval:** Between-arm difference in 0-10 NRS pain change (positive = more pain reduction with HYP-CT).

**Moderator to consider:** Do patients with neuropathic vs nociceptive SCI pain, or those with higher baseline pain, respond differently?

## Design

- Allocation: RANDOMIZED; model: PARALLEL; purpose: TREATMENT
- Masking: SINGLE ['OUTCOMES_ASSESSOR']
- Enrollment: 88 (estimated)
- Phase: NA
- Status on registry: ACTIVE_NOT_RECRUITING; start 2023-09-18; primary completion 2026-07-30 (estimated)

## Arms

- **Hypnosis Enhanced Cognitive Therapy** (experimental): This arm will receive 4 sessions of hypnosis enhanced cognitive therapy for pain. Subjects will receive recordings of sessions for practice between therapist sessions.
- **Pain Education** (active comparator): This arm will receive 4 sessions of spinal cord injury pain education. Subjects will receive pain education materials for review between therapist sessions.

## Primary outcome(s) as registered

- **0-10 Numerical Rating Scale of Pain change score (Decrease in Pain following live Session with Therapist)** (2 times per week for 4 weeks): 0 - 10, self-reported rating of pain. Possible scores range from 0 (no pain) to 10 (pain as bad as you can imagine)
- **0-10 Numerical Rating Scale of Pain (Pain Relief following Practice Sessions)** (1 time per week for 4 weeks): 0 - 10, self-reported rating of pain. Possible scores range from 0 (no pain) to 10 (pain as bad as you can imagine)
- **Self-reported estimate of amount of time post therapy session that pain relief persists** (1 time per week for 4 weeks): Minutes and/or hours after therapy that pain relief persists
- **Self-reported estimate of amount of time post practice session that pain relief persists** (1 time per week for 4 weeks): Minutes and/or hours after practice session that pain relief persists
- **0-10 Numerical Rating Scale of Pain (Weekly average pain intensity)** (1 time upon enrollment, 1 time after 4 weeks (HYPCT/ED Completion), 1 time at 6 month Follow-up, 1 time at 7 month follow-up.): 0 - 10, self-reported rating of pain. Possible scores range from 0 (no pain) to 10 (pain as bad as you can imagine)

## Registry summary

Chronic spinal cord injury (SCI) pain is complex and difficult to treat. For individuals with SCI, pain often begins early in the course of their SCI and continues longitudinally. Unfortunately, SCI-related pain is frequently not responsive to medical treatment and medical treatments that are available and commonly used, such as opioids, have negative side-effects and risk of addiction. Nonpharmacological (non-medication) interventions to reduce chronic pain show promise both for individuals with SCI as well as other chronic pain conditions. Research on psychological interventions for chronic pain over the past two decades has consistently found these interventions to be more effective than no treatment, standard care, pain education, or relaxation training alone. However, many of these interventions are designed and implemented in outpatient settings after chronic pain has already developed. The development of early, effective, and preventative interventions to reduce the development of chronic pain has the potential to vastly improve quality of life for individuals with SCI.

Having demonstrated the feasibility and acceptance of this treatment in an earlier study, the purpose of this randomized clinical trial is to compare the treatment of Hypnosis Enhanced Cognitive (HYPCT) therapy to Pain Education (ED) for reducing acute and chronic pain for individuals with new spinal cord injuries. The main goals of the study are to:

* Aim 1: Test the effectiveness of HYPCT during inpatient rehabilitation for SCI compared to a ED for reducing current pain intensity.
* Aim 2: Determine the post-intervention impact of HYPCT sessions compared to ED on average pain intensity.

Participants will be asked to:

* Complete 4 surveys over seven months
* Complete pre and post treatment pain assessments for each of 4 treatment/control sessions

Participants will be assigned to one of two groups for treatment and receive either:

* 4 Hypnotic Cognitive therapy sessions or
* 4 Pain Education sessions

## Registry detailed description

The purpose of this study is to see if a novel psychotherapy is helpful for reducing pain in patients who been recently diagnosed with a spinal cord injury (SCI). This therapy is an in-person hypnosis enhanced cognitive therapy designed to help people with a recent SCI cope with the pain that may come with that injury. Hypnosis enhanced cognitive therapy will be compared to pain education. Pain education is a semi-standard course which instructs patients with SCI about the types, causes, and usual treatments for pain associated with SCI. This study will be conducted with newly diagnosed patients completing their initial inpatient rehabilitation treatment at Harborview Medical Center in Seattle, WA.

Subjects who meet eligibility criteria and consent to take part in this study will be randomly assigned to one of two groups. One is hypnosis enhance cognitive therapy (HYPCT) group and the other is the pain education (ED) group. Subjects cannot choose which group to be in.

Hypnosis Enhance Cognitive Therapy Group:

Participants assigned to this group will work with a psychologist (PhD) who will provide them with HYPCT. There will be 4 therapy sessions spread out over the duration of the inpatient stay or at least weekly. Sessions will take place in patient hospital rooms and last approximately one hour. Patients will learn some new information and skills to better cope with pain. Sessions will include a brief hypnosis to help patients think about pain in ways that will reduce their experience of pain. During hypnosis, patients spend a lot of time relaxing and listening to the sound of the psychologist's voice. We will record these hypnosis exercises so that patients can listen to them in between sessions with the psychologist.

Pain Education Group:

Participants assigned to this group will work with a psychologist (PhD) who will provide them with ED. There will be 4 education sessions spread out over the duration of the inpatient stay or at least weekly. Sessions will take place in the patient hospital rooms and last approximately one hour. Patients will be educated about pain, including its causes, neurophysiology, nature, and impact. There may be both general pain information as well as information tailored to the SCI specific symptoms. These will be interactive and patients will discuss the content with the therapist. Patients may listen to audio recordings, review educational information and think about what they learned between sessions. Upon completing the study, everyone in the pain education group will be offered the 6 standardized hypnosis audio recordings provided to the HYPCT group. ED group will be asked to complete a survey one month after receiving the standard hypnosis recordings.

Both groups will be asked to complete a baseline survey asking about their demographics, health, and pain. A second survey will be completed after completion of the treatment sessions (HYPCT and ED), a survey will be completed 6 months after that, and then a final survey one month later (at approximately 7 months). The surveys will ask questions about the patient's pain, the treatment of their pain, mood, and sleep quality. A trained research assistant will administer the surveys in person during the rehabilitation hospital stay and by telephone after discharge. These surveys will each take 30-45 minutes. For both groups, before and after each session, patients will be asked about their pain levels and relief. This should take less than 2 minutes.
