What is it? Using movements of appropriate force, speed, or extent when interacting with task objects (AOTA, 2014, p. S25). 

Why is it important? Calibration is a skill necessary for occupations across the lifetime such as: 

  • Bathing/showering (squeezing soap bottles enough to release an appropriate amount of soap, not scrubbing body too hard, etc.) 
  • Toileting 
  • Eating (chewing with an appropriate amount of force) 
  • Feeding (appropriate amount of force to successfully bring food to mouth) 
  • Grooming 
  • Academic performance (writing, cutting, typing) 
  • Driving (not applying too much force to pedals, turning the wheel with appropriate speed and force) 
  • Home management 
  • Opening doors, drawers, and containers (enough force to open/close without slamming) 
  • Play and leisure activities (golf, soccer, basketball, etc.) 
  • Job performance
