Unit 3 Flashcards
Define Motor Tone
Inherent tension in a muscle at rest.
Define Hypotonia
Abnormally low muscle tone
Define Hypertonia
Abnormally High muscle tone
Define Spasticity
Motor disorder: Velocity dependent movements + increase muscle tone.
List the conditions where altered tone may be present for Hyper + Hypo
Hyper: SCI, Brain Injury
Hypo: SCI, Brain Injury
What is the goal for Hypo?
To protect joints
What is the goal for Hyper?
Maintain soft tissue length + mobility
List the Facilitation techniques for Hypo
TVCM
Tapping, Compression (Strong), Vibration + Massage (light)
List the Facilitation techniques for Hyper
TTCM
Tapping, Traction, Compression (light) + Massage (strong)
For ROM exercise for Hypo, what must the RA rememebr
- Support limb (above/below).
- Move moderately quickly thro small ROM
- Dont push to extreme ROM.
- No traction
For ROM exercise for Hyper, what must the RA remember
- Light pressure on palmar/plantar.
- Move full ROM.
- Rot, Traction or light compression to “break” tone.
Define Rigitity
An Increase in muscle tone = resistance to passive motion (stiffness).
Define Dystonia
Movement disorder = disordered tone + involuntary movements.
Name the 3x basic concepts for positioning a client with altered tone
- Maintain Symmetry
- Promote a midline position
- Min the effect of tone
Why would a hypertonia client not be suitable for supine postion
Promotes extreme tone
