PG - 7-11 LID - S1466-853X(17)30051-2 [pii] LID - 10.1016/j.ptsp.2017.06.002 [doi] AB - BACKGROUND: Botulinum Toxin-A (BoNT-A) is an effective intervention for Functional Popliteal Artery Entrapment Syndrome (FPAES) however, concerns with this intervention include reductions in strength and performance. CASE REPORT: This case presents an elite male athlete with FPAES who underwent BoNT-A injection and the results of testing before and after injection. The athlete experienced a decrease in strength and performance at one week post-injection however, he returned to baseline levels within four weeks. When comparing sprint distance during games, before and after injection, the athlete had an increase in his sprint distance per game post-injection. Finally on ultrasound he had visible medial gastrocnemius denervation atrophy with a decrease in arterial flow velocity at four weeks post-injection. CONCLUSION: BoNT-A may be an effective minimally invasive treatment option for FPAES however, athletes may experience a transient decrease in function following BoNT-A injection and consequently caution must be taken with regard to treatment timing.
