The compression block technique: use and misuse in the study of motor skills

Laszlo and Bairstow (1971b) claim that the compression block technique eliminates kinesthetic feedback prior to motor impairment and loss of motor control. They use evidence from studies employing the block to infer the nature of motor-skills processing. The present study, using two-point threshold, pro-prioceptive sensitivity, and hand and finger strength measures, yielded no evidence that afferent loss preceded loss of motor control.
