Question 1

HiMAT

Answer 1

High level Mobility Assessment Tool
• Designed for higher functioning brain injured adults (ie
91/91 on COVS but not fully functioning / co-ordinated)
• 11 different walking, running, hopping, skipping, jumping
and stair items.
• Measure with a stopwatch or tape measure

• Inter-rater reliability of 3 PTs on 17 TBI patients -
ICC=0.99 (Williams, 2006)
• Testretest reliability of 1 PTs on 20 TBI patients -
ICC=0.99 (Williams, 2006)

Question 2

HiMAT 2

Answer 2

• Patients perform each task at their maximum safe speed
(except for bounding and stair items)
• Results are recorded on 5 point scales
• Items are then summed for a total score.
• Norms
– Chronic TBI 32.6 (+/-13) (Williams, 2006)
– MDC and MCID not established

Question 3

types of cerebral artery deficitis

Answer 3

• MCA = more loss to arm rather than leg
• ACA = more loss in LL
• If loss of blood/mvmt to cerebellar = ataxia, but won’t be weak or have sensory loss
• PCA Posterior cerebral artery = will have significant speech issues

Question 4

• Difficulty preshaping in grasp

Answer 4

o Hand may not open or open excessively
o Hand/thumb/finger not orientated for object size, shape, weight
o Not smooth or coordinated closure or appropriate force
o Difficulty building up force and susataining force
o Fluctuation is force

Question 5

• Common adaptive features in grasp

Answer 5

o forearm pronation
o Wrist flexion and ulnar deviation
o Thumb add, limited abd/F to open hand
o Fingers flex all at once

Question 6

• In hand manipulation skills

Answer 6

o Translation – fingers to palm to fingers
o Shift – move fingers up and down an obkect
o Rotation – simple and complex

Question 7

• Post stroke hand

Answer 7

o Difficulty releasing objects cause weak ex and overactive flexors
o Clumsiness
o Loss of movement synsergies between fingers and thumb

Question 8

walking - inconsistent step length

Answer 8

When walking = inconsistency in length/steps is a co-contraction issue not length (length is consistent)

Question 9

Tight posterior capsule

Answer 9

blocks hip extension however won’t get hypextension and is consistent

Question 10

Circumduction

Answer 10

= due to poor hip ext or PF in pre swing – don’t have enough push through so hip flexors compensate

Question 11

Flexor spasticity (gait)

Answer 11

• can’t extend hips or knees due to involuntary flexion of hips and knees = spasticity of hammies

Question 12

Extensor spasticity –

Answer 12

can’t flex hips or knees due to involuntary ext./straightening of the leg= spasticity involves the quadriceps and adductors
