Sensori-Motor Impairments After Stroke (Week 2) Flashcards
Increased tone can be due to
Contracture, spasticity or excessive muscle activity
Secondary impairments following stroke may include
Loss of fitness Shoulder pain and subluxation Learned non use Swelling Loss of fitness
Negative impairments may include
Loss of strength, sensation or coordination
Which impairments have the greatest impact on activity?
Negative. (Strength has the stronget association with activity limitations)
In the 70s and 80s - emerged that movement problems due to weakness of agonist muscle rather than excess antagonist activity. Reduction of spasticity does not improve activity
TARDIEU SCALE 0
No resistance throughout passive movement
TARDIEU SCALE 1
Slight resistance throughout with no clear catch at a precise angle
TARDIEU SCALE 2
Clear catch at a precise angle followed by release
TARDIEU SCALE 3
Fatigable clonus (
TARDIEU SCALE 4
Unfatigable clonus (>10 secs)
TARDIEU SCALE 5
Joint immobile
Tardieu scale description
Measures velocity dependent. Limb moved ast 3 speeds - V1, V2, V3
Strengthening very weak muscles – active
exercise
• How to elicit movement
– Eliminate gravity
– Eliminate friction
– Different parts of range
– Eccentric/isometric/concentric contractions
– Shorten/ minimise impact of the lever arm
– Reduce degrees of freedom
Loss of coordination after stroke is due to
Loss of UMN
Characteristics of loss of co-ordination after
stroke
- Loss of spatial accuracy
- Loss of temporal accuracy
- Jerky movement trajectories
- Excessive muscle activity/ co-contraction
