About this study

Official title: Effectiveness of a Psychological Intervention for the Control and Prevention of Pain and for Surgical Recovery in Patients Undergoing Total Knee Arthroplasty: a Prospective Randomized Controlled Trial

The purpose of this study is to evaluate the effectiveness of a combined Pain Neuroscience Education (PNE) and Hypnosis (HyP) psychological intervention aiming at the control and prevention of pain and promotion of post-surgical recovery in patients undergoing Total Knee Arthroplasty

Read the detailed description

This is a prospective Randomized Controlled Trial (RCT), comparing an experimental group (EG), submitted to a PNE/HyP based psychological intervention, and a control group (CG), submitted to usual treatment and care.

After recruitment and evaluation of inclusion/exclusion criteria, patients entering the study will sign the Informed Consent. Baseline evaluation is performed at 1 month pre-surgery and, afterwards, patients are randomly assigned to EG (PNE+Hyp plus usual care) or CG (usual care only). The EG will be submitted to 3 pre-surgical and 1 (or 2) post-surgical reinforcement sessions. At 1 month post-surgery, the intervention group will be subdivided and participants will be randomly assigned to receive a reinforcement session or no intervention at this point. The psychological intervention sessions are based on the educative principles of Pain Neuroscience Education and on Hypnosis strategies for the promotion of pain control, positive coping strategies and psychological variables.

Patients will be evaluated on 6 moments: T0 - baseline, 1 month pre surgery; T1 - post intervention/24h before surgery; T2 - 72h post-surgery; T3 - 1 month post surgery; T4 - 6 months post surgery; T5 - 12 months post intervention. Patients will fill in self report measures and perform physiological evaluation to analyse relevant bio-markers (salivary cortisol and α-amylase) that are related to stress levels and SNS functioning and translate the impact of psychological interventions on physiological parameters.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PNE+HyPOther

    This is a combined PNE and Hypnosis psychological intervention. PNE is a cognitive based approach that highlights the biopsychosocial model of pain and focuses on neurophysiological and neurobiological processes and pain representation. Hypnosis aims at promoting pain control, increasing positive coping strategies, and targeting positive psychological variables.

Questions about this trial

What is this clinical trial studying?

A study testing PNE+HyP in people with Knee Arthroplasty, Total, run by University of Minho at 1 site in Portugal.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 30 Apr 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Portugal. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early (reason given: Unavailability of the clinical team). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pain intensity post-intervention as assessed by Numerical Rating Scale (NRS) and WOMAC (time frame: 24h before surgery). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Apr 2021.
