What You Need to Know Before You Apply

What is the purpose of this trial?

Conditioned pain modulation (CPM) a measure of the effectiveness of the descending pain pathway and therefore a measure of the body's ability to perform endogenous analgesia. In subjects with normal function of the descending pain pathway, the net-effect during CPM testing is anti-nociceptive, or inhibition of the ascending pain pathway. In those with impaired descending pain pathway function, the response to CPM testing is pro-nociceptive, indicating that the body is unable to inhibit the pain signal, or may even amplify it. There is literature that supports the presence of impaired CPM, and therefore impaired descending pain pathway function, in numerus chronic pain conditions, including low back pain. Impaired descending pain pathway function may be contributing to this chronic pain presentation. This study will give us information on whether a typical physical therapy plan of care is able to improve impaired CPM, and if CPM values are predictive of improvement in physical therapy.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Is physical therapy safe for humans?

Physical therapy is generally considered safe for humans, as it is a common treatment for various conditions, including low back pain. The research does not report any specific safety concerns related to physical therapy. ^{1 2 3 4 5}

How is physical therapy unique for treating low back pain?

Physical therapy for low back pain is unique because it involves a variety of techniques such as exercise, manual manipulation, and heat application, which can be tailored to individual needs. It also allows for direct access to services, potentially reducing healthcare costs and improving outcomes by starting treatment early. ^{6 7 8 9 10}

What data supports the effectiveness of the treatment physical therapy for low back pain?

Research shows that physical therapy can lead to improvements in disability and pain for patients with low back pain, although the effects are often small. Some studies suggest that patients can experience clinical improvement within a few therapy visits, and targeting the hip during therapy may also help reduce pain and disability. ^{11 12 13 14 15}

What Are the Treatments Tested in This Trial?

Interventions

• Physical therapy

Trial Overview The study tests if standard physical therapy can improve the body's natural pain inhibition (conditioned pain modulation) in people with chronic low back pain. It also examines whether this modulation predicts the success of physical therapy treatment.

How Is the Trial Designed?

Published Research Related to This Trial

Physical therapists must effectively track outcomes for patients with low back pain to monitor treatment effectiveness, and this article reviews various measurement tools to aid in that process.

The article discusses the reliability and validity of common outcome measures, such as the SF-36 and Oswestry Questionnaire, providing practical guidelines for their selection and use in clinical practice.

In a study of 6,523 patients with low back pain, 42.7% achieved a 30% improvement in disability by the third physical therapy visit, and this increased to 49% by the sixth visit, indicating that many patients benefit from early intervention.

The initial and third visit disability scores were strong predictors of improvement, with excellent diagnostic accuracy (area under the curve values of 0.84 and 0.85) for forecasting significant clinical progress by the sixth visit, highlighting the importance of routine outcome assessments in physical therapy.

Significant Clinical Improvement Was Predicted in a Cohort of Patients With Low Back Pain Early in the Care Process. Brennan, GP., Snow, G., Minick, KI., et al.[2023]

Patients with low back pain (LBP) who had symptoms for more than 6 months showed significantly less functional improvement after physical therapy compared to those with symptoms lasting less than 1 month, indicating that longer symptom duration may hinder recovery.

The study found that age, symptom duration, and specific types of exercises (mobilization/manipulation, strengthening, and flexibility) significantly influenced functional improvement, explaining over 55% of the variance in recovery outcomes.

A systematic review and meta-analysis of six randomized controlled trials involving 387 participants found that hip-targeted physical therapy interventions did not lead to significant reductions in pain or disability for patients with low back pain.

The studies showed a trivial effect size for pain outcomes and a small effect size for disability, indicating that these interventions may not be effective, and all studies had a high risk of bias.

Early physical therapy (PT) for acute low back pain significantly reduces short-term pain and disability compared to non-PT care, with a moderate effect size based on a meta-analysis of 7 studies involving various participants.

However, early PT does not show significant advantages over delayed PT in terms of pain or disability outcomes, indicating that while early intervention is beneficial compared to no therapy, the timing of PT may not greatly impact long-term recovery.
