NCT07527845

Brief Summary

The goal of this clinical trial is to evaluate the feasibility, safety, and initial effectiveness of a new augmented reality (AR) system in adults over 18 years old suffering from chronic low back pain and kinesiophobia (fear of movement). The main questions it aims to answer are: Is the AR system safe to use and well-tolerated by participants without causing significant motion sickness or discomfort? Can the visual "illusion" provided by the AR technology help patients increase their range of motion and reduce their fear of bending forward? Participants will:

  • Perform 10 to 12 repetitions of spinal bending exercises while wearing an AR headset that shows a video of them moving further than they actually are.
  • Complete questionnaires regarding their pain levels, physical disability, and fear of movement.
  • Report any symptoms of "cybersickness" (like dizziness or nausea) experienced during the use of the technology.
  • Participate in a brief interview to discuss their experience, how they felt using the device, and provide suggestions for improvement.

Outcome Measures

Primary Outcomes (1)

  • Simulator Sickness Questionnaire (SSQ)

    A standardized questionnaire used to evaluate symptoms of cybersickness (dizziness, nausea, etc.) associated with the use of the AR headset. It measures 16 symptoms across three subscores: Nausea, Oculomotor, and Disorientation. The total score represents the overall severity of the symptoms.

    Immediately after the technology testing session (single assessment)

Secondary Outcomes (2)

  • Peak Angle of Spinal Forward Bending

    During the intervention session (recorded across 10 to 12 repetitions)

  • Qualitative Feedback on System Experience and Safety

    Immediately following the intervention session

Study Arms (2)

Healthy Volunteers (Pilot Phase)

Description: A group of healthy volunteers (n=7) over 18 years old with no chronic pathologies or musculoskeletal conditions Role: This group was used for the initial testing and iterative development of the AnReal system to evaluate user experience and baseline cybersickness. Feedback from this group led to technical modifications of the software before testing it with the clinical population

Device: Augmented Reality (AR) Rehabilitation System

Patients with Chronic Low Back Pain (Feasibility Phase)

Description: A group of patients (n=10) over 18 years old diagnosed with non-specific chronic low back pain for more than three months, presenting with kinesiophobia and limited range of motion (less than 40 degrees of spinal forward bending). Role: This is the primary clinical cohort used to evaluate the feasibility, safety, and potential impact of the AR-based intervention on pain-related fear and physical movement

Device: Augmented Reality (AR) Rehabilitation System

Interventions

System Components: An Android-based mobile application used in conjunction with a low-cost virtual reality (VR) headset. Technical Core: The system integrates computer vision algorithms and artificial intelligence to track and analyze spinal forward bending in real-time. Visual Feedback Loop: It creates a visual illusion of continued movement, showing the patient's body performing a greater range of motion than they are actually executing. Mechanism: This task-specific intervention uses visual cues and graded exposure to reduce fear of movement (kinesiophobia) and encourage a greater range of motion in patients with chronic low back pain

Study Population

The study population consists of two distinct groups recruited for a proof-of-concept and a feasibility trial. The first group includes healthy adult volunteers used for the initial technical validation of the system. The primary clinical group consists of adult patients suffering from non-specific chronic low back pain and kinesiophobia, specifically characterized by a significant limitation in spinal range of motion. All participants were evaluated in a controlled research environment to assess the safety and performance of the AR technology

You may qualify if:

  • Participants must be over 18 years old.
  • For the pilot phase: Healthy volunteers with no chronic pathologies or musculoskeletal conditions
  • For the clinical phase: Diagnosis of non-specific chronic low back pain (CLBP) lasting longer than three months.
  • For the clinical phase: Presence of less than 40 degrees of spinal forward bending movement.

You may not qualify if:

  • History of spine surgery.
  • Diagnosis of vestibular disorders.
  • Diagnosis of Meniere's syndrome
