Objective: The objective of this study was to determine the effects of an acute lateral ankle sprain on self-reported function, self-reported pain, self-reported global function, joint effusion, dorsiflexion range of motion, and dynamic stability over a 14 day period following injury compared to healthy matched controls. Design and Setting: A case-control design was conducted in a laboratory setting. Subjects: Twenty-nine participants with an acute lateral ankle sprain (LAS) were assigned to a LAS group (10 males, 19 females; 20.41 ± 2.18 years; 176.44 ± 11.00 cm; 74.22 ± 14.33 kg), and twenty-two healthy participants were assigned to a control group (11 males, 11 females; 20.95 ± 2.97 years; 178.61 ± 10.96 cm; 76.39 ± 13.81 kg). Procedure: Experimental measures All participants were asked to report for a total of five tests sessions done at 36 hours, 5, 7, 10, and 14 days following initial injury; or from the day of enrollment as a healthy control. Each testing session lasted approximately 1 hour, with self-reported function and self-reported pain was assessed using the FADI, FADI Sport and VAS. Dynamic balance was assessed using the SEBT anterior, posteromedial, and posterolateral reach directions. Ankle girth was measured using the figure-of-eight method. Dorsiflexion range of motion was assessed using a goniometer. Frequency of rehabilitative exercises athletic, athletic participation and use of therapeutic modalities was collected using a treatment questionnaire. Results: Significant differences were found fourteen days following injury in all self-reported outcomes in the LAS group compared to Healthy controls (P=0.05). Significant decreases DF were found up to seven days post injury (P=0.05). Significant dynamic stability deficits were seen up to fourteen days following injury in the anterior reach and posteromedial reach of the star excursion balance text (SEBT) (P=0.05). No significant findings were seen in the posterolateral reach direction of the SEBT (P=0.05) at any time point. No significant findings were seen in ankle girth (P=0.05) at any time point. Conclusion: Those who suffer from a LAS exhibit decreased self-reported function, decreased dynamic postural control, decreased DF range of motion, increased self-reported pain, and increased ankle girth. While studies investigating acute function alterations in ankle sprains for 14 days following injury are limited, these results should be taken into consideration when making rehabilitation and return-to-play decisions. Clinicians may need to consider the possibility that a LAS return-to-play protocol time frame should be increased further than two weeks post injury. Word Count: 396
