Brief summary
To evaluate the effect of virtual reality mindfulness meditation on patients after ACLR, the investigators will determine the effect of virtual reality mindfulness meditation to 1) decrease self-reported injury-related fear, 2) improve poor jump-landing movement patterns, and 3) improve brain activity in women 1 to 5 years post-ACLR when compared to a virtual reality sham group.
Detailed description
Injury-related fear after anterior cruciate ligament (ACL) injury significantly contributes to decreased return to sport, decreased physical activity engagement, and increased ACL reinjury risk in previously high functioning, physically active individuals. Injury-related fear is also associated with poor jump-landing movement patterns in patients after ACL reconstruction (ACLR). Unfortunately, current rehabilitation practices do not specifically address injury-related fear in patients after ACLR. Virtual reality mindfulness meditation is a mental practice that involves focusing the mind on experiences in the present moment and has been used to address depression, anxiety, and chronic musculoskeletal pain. To evaluate the effect of virtual reality mindfulness meditation on patients after ACLR, the investigators will determine the effect of virtual reality mindfulness meditation to 1) decrease self-reported injury-related fear, 2) improve poor jump-landing movement patterns, and 3) improve brain activity in women 6 months to 10 years post-ACLR when compared to a virtual reality sham group. Patients in the intervention group will complete 8-weeks of virtual reality mindfulness meditation + an advanced rehabilitation training program. Patients in the sham group will complete 8-weeks of the virtual reality sham + an advanced rehabilitation training program. The central hypothesis is that women 6 months to 10 years post ACLR who undergo virtual reality mindfulness meditation will demonstrate decreased injury-related fear, improved jump-landing movement patterns, and improved brain activity.
Interventions
BEHAVIORALVirtual Reality Mindfulness Meditation
Participants will be immersed in a virtual environment of their choosing. While in the virtual environment, participants will follow a guided mindfulness meditation script. Participants will complete the intervention 3 times a week over the course of 8-weeks.
BEHAVIORALVirtual Reality Sham
Participants will be immersed in a virtual environment of their choosing, such as at a beach, forest, or lake.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of participants who were eligible and enrolled in the study | Through study completion, a total of approximately 3 years. | Feasibility of the Virtual Reality and Advanced Neuromuscular Training Rehabilitation Program will be assessed through established recruitment for patients post-ACLR. Recruitment is defined as the percentage of participants who were eligible and enrolled in the study. |
| Percentage of participants retained in the study | Through study completion, a total of approximately 8-weeks | Feasibility of Virtual Reality and Advanced Neuromuscular Training Rehabilitation Program will be assessed to determine participant retention. Retention is defined as the percentage of participants enrolled and who have completed all study measures through 8-weeks. |
| Mean Acceptability Survey Score | Collected post-treatment after completion of the intervention/sham at week 8 | Feasibility of Virtual Reality and Advanced Neuromuscular Training Rehabilitation Program will be assessed via an acceptability survey during the final assessment post-treatment at week 8. Mean score greater than 8 will be interpreted as high acceptability. |
| Change in Injury-related fear as measured by the Tampa Scale of Kinesiophobia-11 | Collected at baseline and post-treatment after completion of the intervention/sham at week 8 | The Tampa Scale of Kinesiophobia-11 is a patient-reported outcome measure that assesses fear of movement and/or reinjury. This is an 11-item questionnaire that is valid. Scores range from 11 to 44, with higher scores indicating elevated fear. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in external knee abduction moment | Collected at baseline and post-treatment after completion of the intervention/sham at week 8 | External knee abduction moment is a biomechanical assessment pertinent to patients with ACL reconstruction. Increased knee abduction moment has been associated with ACL reinjury risk. Patients will complete a jump-landing task to assess knee abduction moment using a three-dimensional motion capture system and embedded force plates. |
| Change in knee flexion excursion | Collected at baseline and post-treatment after completion of the intervention/sham at week 8 | Knee flexion excursion is a biomechanical assessment pertinent to patients with ACL reconstruction. Decreased knee flexion excursion has been associated with ACL reinjury risk. Patients will complete a jump-landing task to assess knee flexion excursion using a three-dimensional motion capture system and embedded force plates. |
| Change in Mean percent Blood Oxygen Level Dependent signal in Default Mode Network. | Collected at baseline and post-treatment after completion of the intervention/sham at week 8 | Blood Oxygen Level Dependent (BOLD) fMRI is a non-invasive diagnostic method of assessing brain activity by detecting signal changes secondary to changes in blood flow and oxygenation. Increased mean percent BOLD signal is associated with increased brain activity and decreased mean percent BOLD is associated with decreased brain activity. BOLD signal will be measured during a picture imagination task with sport-specific images and activity of daily living (ADL) images presented during the fMRI scan. Images are presented for 3 seconds with a 12-second rest between images. Whole brain functional images will be collected via a 3T PRI Scanner. Functional data will be acquired with BOLD echoplanar imaging (EPI) and processed using Analysis of Functional NeuroImages (AFNI). Mean BOLD percentage change based on image category, sport-specific versus ADL, will be examined. |
