To evaluate the effect of graded exposure and mindfulness meditation after ACLR, the investigators will determine the effect of graded exposure and mindfulness meditation to 1) decrease self-reported injury-related fear and reinjury anxiety, and 2) improve lower extremity reaction time when compared to a waitlist control group.
Ages 14-35 years
Have self-reported levels of fear on the Tampa Scale of Kinesiophobia-11 and the Photographic Series of Sports Activities for ACLR
Injured their knee playing or training for sports (recreational or organized)
Have a history of unilateral ACLR
History of secondary ACL injury
Do not exhibit elevated injury-related fear
Concomitant surgeries at the time of ACL reconstruction
Parallel
Graded Exposure and Mindfulness Meditation
BehavioralParticipants will complete graded exposure and will be encouraged to face fear-eliciting situations. Participants will also complete mindfulness meditation guided through the Headspace mobile application. Participants will complete the graded exposure one time per week and will complete the mindfulness meditation 4 times per week.
Waitlist Control
BehavioralParticipants will receive an email stating that they will receive access to 5-weeks of Headspace after 5-weeks. Participants will be also asked to not change their normal routines or download apps for relaxation, meditation, or sleep during 5-weeks. After completion of the outcome assessments at 5-weeks, participants in this group will receive access to 5-weeks of Headspace.
Change in Task Specific Fears
The Photographic Series of Sports Activities for ACLR is a patient-reported outcome designed to measure fear of harm of specific tasks through photographical assessment. Patients will be instructed to rate each photograph of sports activities on a scale of 0 to 10, with 0 representing "not harmful at all" and 10 representing "extremely harmful."
Change in Overall Injury-Related Fear
The Tampa Scale of Kinesiophobia-11 is a valid and reliable questionnaire that consists of 11-items and evaluates fear of movement and re-injury. A 4-point Likert scale is used to score each item. Scores range from 11-44 with higher scores representing higher kinesiophobia. AIM 1: Determine the efficacy of GEMM compared to a waitlist control group to decrease injury-related fear and reinjury anxiety in participants with a history of ACLR 1-5 years post-reconstruction.
Change in Reinjury Anxiety
The reinjury anxiety inventory (RIAI) is a valid and reliable 28-item questionnaire of reinjury anxiety which consists of two subscales, rehabilitation reinjury anxiety and reentry into competition reinjury anxiety. A 4-point Likert scale is used to score each item. The RIAI is scored by computing a separate score for the two subscales and adding these scores together for an overall total score. Total score ranges from 0-84 with higher scores representing higher reinjury anxiety
Change in Lower Extremity Reaction Time
Participants will complete a standardized and novel lower extremity reaction time assessment using the FitLight Trainer. Participants will be instructed to respond to a visual stimulus and deactivate a series of 5 targets arranged in a semicircle with their feet. The protocol will last for 1 minute and completed bilaterally. Test limb order will be counterbalanced between participants. Participants will complete 3 familiarization trials and 1 test trial per limb (ms).
