Rood Flashcards
Contracture:
Fixed posture secondary to shortening or loss of elasticity of ligaments, joint capsule, tendons, and muscles (Preston & Hecht, 1999).
Controlled Sensory Stimulation:
Concept that the neural component of tone can be affected by sensory stimuli applied in a specific manner to increase or reduce the electrical charge on interneurons or motor neurons, making them more or less likely fo fire when they receive additional goal-specific stimulation from supraspinal centers.
What is the purpose of Facilitating
To make easier.
Facilitation:
State of readying neurons to depolarize and propagate an impulse or to make contraction of a muscle or a reflex response more likely.
Facilitation techniques:
blood pressure increase.
Controlled sensory stimulation used to increase muscle tone and to produce movement responses.
Fight or flight reaction:
Sympathetic autonomic nervous system response to a threat (fear, rage, pain, exposure to cold) that mobilizes the body’s resources for violent action. The Sympathetic reaction redirects blood flow to areas of intense activity, such as muscles and heart, and away from other functions, such as digestion. Among other reactions, the heart rate and blood pressure increase.
Flaccidity:
State of lacking tone; the limb feels limp and falls into place when not supported.
Inhibit:
To make more difficult.
Inhibition:
State of hyperpolarization of neural cell membrane decreasing likelihood of propagating an impulse or to make contraction of a muscle or a reflex response less
likely.
Inhibition techniques:
Controlled sensory stimulation used to decrease spasticity.
Normalization of tone:
Process of changing excessive tone (hypertonia) or insufficient tone (hypotonia) to a state of normal tone needed for normal motor responses.
Spasticity:
State of excessive tone and hyperactive response to stretch. If moderately to severely spastic, the limb feels tight and is difficult to move into position.
Rood’s hypothesis states Appropriate Sensory
stimulation Facilitation/inhibition does what?
Increases Reactions of specific motor responses
Rood’s hypothesis states Purposeful muscular responses are a result of
Controlled sensory stimulation + Sequence of positions and activities
Muscle tone and motor control do what

what patterns co-effect each other.
Flex & Ext.
Movement patterns are created by
Repetition of muscular responses

to select interaction methods.
What are Rood’s treatment goals
To normalize muscle tone.
Development of reflexes to increase voluntary use of muscles.
What are the muscle groups
Heavy work and Light work
Heavy work muscles
(Stabilizers)
Extensors and abductors
used for postural support
Light work
(Mobilizers)
Adductors and flexors
used for skilled movement patterns
