1. Constraints of the individual due to impairments resulting from injury (EX: UE synergy is a
constraint)
2. Requirements of the specific task (EX: adapting hand shape to pick up cup is a requirement
of the task)
3. Environmental elements affecting task performance (EX: Height of the table the cup is sitting
on is environmental element) - Answers The success of task performance involves these 3
factors:
UE synergy following a stroke - Answers Example of a constraint of individual
Adapting shape of hand to pick up coffee cup - Answers Example of task requirement
Height of the table the cup is sitting on - Answers Example of environmental element
anticipating; planning - Answers Feed forward control of a task involves ___________ specific
variables of a task and _______ movements accordingly
1. Locating target (coordination of eye and head movements)
2.Reaching (Transportation of arm and hand along with postural control)
3. Grasp (Grip shape formation, grasp/release of object)
4. Hand manipulation of object - Answers 4 key elements needed for successful UE reach, grasp,
and manipulation function:
False. The eyes move FIRST then the head if necessary - Answers True/False The eyes move
AFTER the head moves to locate
