Objective:
The objective of this pilot study was to examine the preliminary feasibility and efficacy of in vivo exposure therapy (IVET) to decrease injury-related fear in females with history of ACLR.
Design:
Pilot Study.
Setting:
Sports Medicine Research Laboratory.
Participants:
12 female participants with history of ACLR (≥ 1 year post-operative) were randomized into a 5-week IVET group (n = 6) or 5-week sham physical activity (PA) monitoring group (n = 6).
Main Outcome Measures:
The independent variables were Group and Time. The dependent variables were the Photographic Series of Sports Activities for ACLR (PHOSA-ACLR) and the Tampa Scale of Kinesiophobia-11 (TSK-11) scores. A Group x Time repeated measures two-way analysis of variance was completed for the PHOSA-ACLR and the TSK-11. Partial η2 effect sizes were used to examine clinically meaningful differences.
Results:
High retention and adherence rates were observed in the intervention group. The PHOSA-ACLR exhibited a significant main effect for Time (F1,10 = 9.92, p = 0.01, partial η2 = 0.50), but not for Group. No statistically significant or clinically meaningful differences were observed for the TSK-11.
Conclusion:
Both groups exhibited decreased injury-related fear for specific functional tasks. Future research should further examine the efficacy of IVET and PA monitoring to decrease injury-related fear in patients after ACLR.
