Task complexity in exoskeleton setup and takedown: Procedural steps and usability problems as predictors of deployment performance.

Critically, the relationship between HTA steps and completion time remained highly significant after controlling for presentation order (partial r = 0.814, p < .001), indicating that the complexity-performance association is not an artifact of cross-device learning.

Although the negative coefficient suggests a trend toward faster completion with later-presented devices, this effect did not reach statistical significance.
