Resolving the Burden of Low Back Pain in Military Service Members and Veterans: A Pragmatic Clinical Trial (RESOLVE)

January 26, 2026 updated by: Sara Gorczynski
The RESOLVE trial will provide a pragmatic approach to evaluate whether Physical Therapy Clinical Practice Guideline adherence can reduce pain, disability and downstream healthcare utilization for low back pain within the Departments of Defense and Veterans Affairs healthcare systems.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Physical therapy (PT) is frequently used for the management of low back pain (LBP) within the U.S. Departments of Defense (DoD) and Veterans Affairs (VA). However, variations in PT practice patterns and utilization of ineffective interventions lower the quality and increase the cost of care. Although, adherence to the clinical practice guidelines (CPGs) can improve outcomes and cost effectiveness of LBP care, PT CPG adherence rates remain below 50%. The RESOLVE trial will evaluate the effectiveness of an active PT CPG implementation strategy using an education/audit/feedback model for reducing pain, disability, medication use and cost of LBP care within the DoD and VA healthcare systems. The RESOLVE trial will include 3300 to 7260 patients with LBP from five DoD and VA medical facilities, using a stepped-wedge study design. An education/audit/feedback model will be used to encourage the physical therapists to better adhere to the PT CPG recommendations. The primary outcomes of disability and pain intensity will be measured with the Oswestry Disability Index and the Defense and Veterans Pain Rating Scale. Secondary outcomes will include the LBP-related medical resource utilization and biopsychosocial predictors of PT outcomes. Statistical analyses will be based on intention to treat principles and will use linear mixed models to compare treatment conditions, and examine the interactions between treatment and sub-grouping status. The RESOLVE trial will provide a pragmatic approach to evaluate whether PT CPG adherence can reduce pain, disability and downstream healthcare utilization for LBP within the DoD and VA healthcare systems.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
4039

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Receiving physical therapy care for low back pain in an outpatient physical therapy setting

Design Details

  • Primary Purpose: Other
  • Allocation: Randomized
  • Interventional Model: Sequential Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
No Intervention: Usual Care Condition
During the usual care condition the therapists will be instructed "to act as usual," that is, to read the guidelines on low back pain if they have read previous published guidelines and not read these guidelines if they have not read any other guidelines.
Active Comparator: CPG+PIPT Condition
An active Clinical Practice Guidelines (CPG) implementation strategy will be utilized with an education component in Psychologically Informed Physical Therapy (PIPT) with peer opinion leaders and a monthly audit/feedback on CPG adherence rates and patient outcomes
Behavioral: Clinical Practice Guidelines and Psychologically Informed Physical Therapy training/audit/feedback
The aim of the active training strategy is to improve the knowledge and skills of physical therapists with regard to evidence-based physical therapy with an emphasis on active treatments and PIPT for the treatment of patients with low back pain and to encourage increased adherence with CPGs. This Continuing Education (CE) training session will be offered to all therapists regardless of study participation. During the CE training session, focus will be placed on interventions that have been shown to be effective, such as interactive education and discussion, feedback, and reminders.

What is the study measuring?
