  1. Power grips
    • •Cylindrical grip
    • •Cylindrical grip variation
    • •Spherical grip
    • •Hook grip
  2. precision grips  or Precision Prehension
    • •Pad-to-pad grip
    • •Three-jaw chuck grip
    • •Tip-to-tip
    • •Pad-to-side grip
    • •Side-to-side grip
    • •Lumbricalgrip = Plate grip
  3. What does prehension mea?
    grip
  4. Cylindrical Grip (power grip)
    • •All fingers flexed around the object
    • •Thumb and fingers in opposite direction •Examples:
    • •Holding a hammer'
    • •Holding a racquet
    • •Holding a wheelbarrow
  5. Modified Cylindrical Grip (power)
    • •Variation, of cylindrical grasp
    • •5th finger flexed the most
    • •2nd finger partly flexed
    • •Allows a more forceful but more controlled used of a tool
    • •Example:  Holding a golf club
  6. Spherical Grip (power)
    • •All fingers and thumb adducted around an object

    • •Example:
    • •Holding an apple or doorknob

    • •PIPs & DIPs in some degree of flexion
    • •Thumb is not usually involved
    • •Only power grip possible if a person has a median nerve injury

  8. Precision Grip

    Pad-to-Pad Grip Pinch Grip
    •Bringing the pads of the finger(s) and thumb together

    •Thumb and one finger together • Usually the index finger • Metacarpophalangeal (MCP)and proximal interphalangeal(PIP) joints of the finger(s) are usually flexed
  9. Pad-to-Pad GripThree-Jaw Chuck (precision)
    • •Involves the thumb and two fingers
    • •Usually the index and middle fingers
    • •Similar to power drill –
    • •three “jaws” pinching on a drill bit
    • •Example: •Holding a pen or pencil dynamic tripod grasp
  10. Pincer Grip Tip-to-Tip Grip (precision)
    • •Involves bringing the tip of the thumb up against the tip of another digit

    • •To pick up a small object
    • • i.e. coin, pin
    • •Difficult with long fingernails
    • •Similar to pad-to-pad
  11. Pad-to-Side GripLateral Prehension (precision)
    • • The pad of the extended thumb pressing an object against the radial side of the index finger
    • • Strong grip, but allows less fine movements than the other two types
    • • Example:  Holding a key
  12. Precision GripSide-to-Side (precision)
    • •Requires adduction of two fingers
    • • Usually the index or middle fingers
    • •Weak grip '
    • •Does not require much precision
    • •Can be used in the absence of the thumb •Example:
    • • Holding a cigarette or pencil
  13. LumbricalGrip = Plate Grip (precision)
    •Thumb opposes the fingers to hold an object horizontally

    •Used when something needs to be kept horizontal such as a plate or tray

    •Metacarpophalangeal (MCPs) flexed

    •Proximal interphalangeal(PIPs) joints and distal interphalangeal(DIPs) joints extended

    •Uses lumbricalmuscles
