This study examined propulsion net joint moment impulses during two single-leg hop tests (SLHTs) frequently used in athletic training as return-to-play criteria. Healthy recreational athletes were statistically compared to those with chronic ankle instability (CAI), during an anterior and a crossover SLHT, looking for differences, potentially leading to compensatory patterns. When comparing CAI to healthy participants there were no significant differences during the crossover SLHT. For the anterior SLHT, significant differences were found during ankle dorsiflexion, ankle inversion, and hip abduction. Statistical comparison was also made between the anterior and the crossover SLHT. Healthy participants had statistical difference in internal knee rotation when comparing anterior SLHTs to crossover SLHTs. No statistically significant differences were found between the anterior and crossover SLHT for CAI participants. These few significant differences allude to the SLHT being insufficient in determining CAI and leave room for other aspects of propulsion kinetics to be examined.
