Neuro CVA - Tone

Question 1

Hypotonicity definition

Answer 1

Floppy, low tone, flaccid, risk of dislocation of AA joint (SCI potential), hip, knee, elbow, shoulder, etc.

Question 2

Hypotonicity - reflexes

Answer 2

Hypoactive reflexes and shallow breathing patterns

Question 3

Hypotonicity treatment

Answer 3

1. Avoid joint hyperextension
2. Work for joint compression and facilitation to help normalize tone
3. Use resistance of functioning mm and isometric holding to inc activation of inactive mm
4. Facilitation techniques eg. quick stretch, tapping of mm belly or tendon, high freq vibration, light touch, quick icing, fast spinning or rolling, joint approximation (facilitates cocontraction)

Question 4

Hypertonicity definition

Answer 4

Spastic, high toner with hyperactive refleces and decreased thoracic mobility

Question 5

Hypertonicity risks

Answer 5

Contractures, deformity

Question 6

Hypertonicity - what affects tone?

Answer 6

Body position

Question 7

Hypertonicty treatment

Answer 7

1. Work to inhibit reflex activity via postures, positions or techniques of relaxation training
2. Prolonged static mm stretch, inhibitory casting, slow repetitive rocking or rolling, very low freq vibration, reflex inhibiting postures, limb movements emphasizing rotation, slow stroking, neutral warmth, prolonged icing, deep pressure to tendons
3. Reciprocal inhibition: using facilitation techniques to the nonspastic mm will cause inhibition of the spastic mm
