Hand Function Evaluation And Intervention Flashcards
Terminology of hand use what are they?
Visual Motor (eye hand coordination) Fine Motor Reach Grasp Carry Voluntary Release In-Hand Manipulation Biannual Skills
What Factors contribute to the development of hand function?
Cultural Influence (Poverty, Utensils, View of Play)
Somatosensory Function (hepatic perception)
Visual Perception and Cognition
Musculoskeletal
Cultural Influence How does it affect Developement of Hand function
Children learn to use tools by watching adults
Poverty- lack of objects to practice
Utensils - May not use
View of play - play may not be important
Somatosensory functions How does it affect Developement of Hand function
Hectic perception
Accurate use of fingers movement
Sustaining grasp
Somatosensory Limitations may cause?
Poor coordination
Problems with timing and speed of response
Clumsiness
Visual Perception and cognition How does it affect Developement of Hand function
Vision is important for learning new motor skills (arching and manipulating)
Attention to objects
Problems solving with objects
Musculoskeletal How does it affect Developement of Hand function
Joint, bone and muscle structure important
Hand Amomalis
Decreased ROM
And Musle power.
Development of Hand Skills what are they?
Reach and carry Grasp patterns In-hand manipulation skills Voluntary release Bimanual skills Throwing ball skills Tool use Hand preference
Reach and Carry 3 months
Bat at an object
Reach and Carry 4 months
Hand Regard
Reach and Carry 12 months
Optimal hand opening to reach and grasp an object
True or False. Carrying - requires smooth body movement and stabilization of object in the hand
Ture
Grasp Patterns Precision vs power ?
Precision - involves thumb opposition And small or medium objects
Power- Involves entire hand, medium or large objects
Grasp Pattern 1-3 months
Grasp reflex
Grasp Pattern 4 months
Voluntary grasp
Grasp Pattern 7 months
Raking
Grasp Pattern 9-12 months
Disk grasping
Cylindrical grasp
Spherical grasp
Grasp Pattern 4-5 years with strength increasing until 12 years old
Lateral pinch
Tripod pinch
What are types of In-Hand Manipulations?
Fingers to palm translation Palm to finger translation Shirt Simple rotation Complex rotation
What are the requirements for development of in-hand manipulation skills ?
Supination
Wrist extension with stability
Controlled dynamic thumb opposition
Finger tip pretension
Isolated thumb and radial finger movements
Stability with mobility of transverse MCP arch
Dissociation of side of hand
Voluntary Release requires what?
Precise coordination of fingertips forces and timing for predicting accurate object placement
Voluntary Release 5-6 months
Transfers object from one hand to the other smoothly
