40
Q

41
Q

45
Q

Normal atypical movement

A

Reflects the motor behavior response of a client/individual when typical movement strategies are temporarily or completely no longer feasible. due to TBI or Stroke sometimes

actions are awkward, inefficient, uncoordinated, conscious thought; low complexity; limited movement options; increased time needed

could lead to perm.disability

46
Q

Normal typical movement

A

Ability to access and select from numerous movement possibilities to produce multiplanar, complex combinations of movement.

Posture:

A

“State of the body in relationship to gravity, the ground and to its body parts or extremities.”

70
Q

A

“The regulation of the body’s position in space for the dual purpose of stability and orientation.”

71
Q

74
Q

Center of gravity (COG

A

the balance point of an object where all sides are equal

75
Q

Principles of stability

A
  1. Lowering the COG will increase stability.
  2. COG and line of gravity must remain in the base of support for stability.
  3. Increasing the base of support will increase the stability.
  4. Increasing the mass will increase the stability.
  5. Increasing friction between the object and surface will increase stability.
  6. Focusing on a spot will increase stability.
76
Q

A

the joint movements as the client alone moves a joint through the available ROM.

Q

Passive range of motion (PROM),

A

refers to joint movement created by the OTA moving the extremity.

78
Q

Active assist range of motion (AAROM)

A

the therapist manually assisting the client to move the joint; however, the client also activates some joint motion.

79
Q

Measurement of ROM with goniometer

A

Has moving arm, stable arm, and axis
Use “neutral zero method” of ROM measurement, meaning when a joint is in neutral position it will measure 0 degrees on the goniometer.

80
Q

NROM

A

0 to 180

81
Q

limiations start on Goniometer

A

25 to 180 degrees identifies ROM limitation at starting position

82
Q

a (-) sign means

A

negative” sign can mean a loss of ROM at the starting position.

83
Q

a (+) sign means

“positive” sign can mean ROM past the starting position for a joint extension or hyperextension.

84
