Maher C,, Adams R. and A psychophysical evaluation of manual stiffness discrimination. Aust J Physiother.  · The effects of two training programs on movement discrimination ability, at the ankle and knee, were assessed from the left and right lower limbs of forty-four football players. All players in three Under 18 Victorian Football League (VFL) squads were allocated to either wobble board training, jump landing training, or no-training conditions.

The within-session reliability (ICC 3,3) for the single measures was estimated from to for the unloaded condition and from to for max tolerable load.. In addition, the within-session reliability estimates (ICC 3,1) for the average of the 3 lumbar spine stiffness measurements ranged from to for the unloaded condition and from to for maximal tolerable load. The comparison is based on a series of psychophysical experiments measuring absolute threshold and just noticeable difference for all conditions. The results clearly show that the perception-based method enhances both detection and discrimination abilities compare with other control methods. One possible explanation for the poor reliability of clinical judgments of spinal stiffness is that humans do not possess a good ability to discriminate stiffness stimuli. This study sought to investigate this hypothesis by conducting stiffness discrimination tests on 72 subjects, using a mechanical device to provide the stiffness stimuli.
