The Askling H-Test

The Askling H-test is used to determine when a hamstring-injured athlete is ready for safe return-to-practice and return-to-competition.  It is a repeated, rapid hip-flexion-to-full-range apprehension test that asks the athlete to grade the severity of their level of fear or apprehension from 0-100 (100 being most severe) three successive maneuvers.  The non-flexing hip is stablized to the table or plinth manually or using straps or belts.

Once symptoms of hamstring tear have resolved with walking and light, slow-speed, controlled running (forward and backward (retro-running), and once hamstring strength is restored, particularly with eccentric loading, this test is the last test used to assess the athlete’s fitness to return.

For the high performance track and field sprinter, where hamstring loads are intense, a subjective Askling H-test score of 1 or more (that is, with ANY apprehension whatsoever) the sprinter should not run at maximum capacity.  However, for an (American) football player,  a score of 1-10, or perhaps 15 would not preclude the athlete from engaging in practice due to the lack of maximum eccentric muscle activity in 1 sustained effort as is done in a 100 meter sprint.
