This case report aimed to highlight the use of the Maximum-Speed Single-Leg Bridge Test (MS-SLBT) in a rugby player with a fourth recurrence of HSI to identify functional impairments that are not detectable with conventional assessments, and to demonstrate that these impairments can be improved by utilizing the test as an intervention.</p><p><strong>Case description: </strong>A 21-year-old university rugby player with a history of three prior HSI experienced a fourth recurrence in the semitendinosus.
