Last week I shared a simple clinical test (Star Excursion Balance Test) that can be used to help guide the decision-making process around returning to sport following lower limb injury.
Here is another one; The Single Leg Hop Test. The goal of this test is to jump as far as possible on each leg, aiming to "stick" the land. The aim is to have the recently injured limb within 10% of the uninjured limb.
Along with other hop tests (triple hop, crossover hop and 6m timed hop), poor performance on hop tests (>10% difference between limbs on all these 4 tests) can identify those at risk of re-injury, especially those that have had ACL reconstruction (Krytsis et al 2016 & Grindem et al 2016).
NOTE: QUANTITY is not only what you should be looking for! Notice the poor QUALITY on the Left leg lands vs Right leg lands. Would you clear me to play?
