Reach to Grasp Flashcards
What are the critical events for reach to grasp? What are the individual aspects of each critical event?
Preparatory phase-Visual Identification of object (head and eyes)
Transport Phase
- dissociation of the trunk and arm
- pre-shaping of the hand
- sufficient acceleration/deceleration of the arm
Grasp Phase
- creation of slip grip force
- modulation of grip force
How can you facilitate muscle activation for reach to grasp movements?
- FES
- Guidance of movement
- Increase load
- EMG
- Mirror box therapy to increase distal muscle activation
- kinesiotape to deltoid
How can you facilitate smoothness and accuracy of reach to grasp movements?
- visual target of path (tape on table)
- vibration of the forearm
What tend to be the easier objects to grasp for reach to grasp movements?
-large objects
-cylinders
-stable
-rough
-rigid
-light
more challenging objects tend to be smaller, spherical, unstable, smooth, compliant and heavy
Which of the following are appropriate progressions for different aspects of reach to grasp activities:
Objects: Use more spherical and smaller sized objects that are less rough
Weighting: Increase weight to decrease the proprioception influence of the weight
Vibration: Increase amount of vibration
Visual Feedback: Close eyes to rely on proprioception
Reach: Less support from surface, greater distance, more antigravity
use more spherical and smaller sized objects that are less rough
Close eyes to rely on proprioception
Less support from surface, greater distance, more anti-gravity
What are the sensory structures during acceleration phase of reach to grasp?
shoulder
elbow
wrist
hand

What interventions are appropriate to address muscle with increased activation/spasticity during reach to grasp?
EMG/FES Pharmacological approach (botox, baclofen, phenol, etc.)
What interventions are appropriate to address muscle with decreased timing/sequencing during reach to grasp?
Mirror box bowls-modify aperature RAS FES/EMG Visual tape on table
What interventions are appropriate to address muscle with decreased proprioception during reach to grasp?
Visual FB tape on table

Mirror box
Kinesiotape
What interventions are appropriate to address muscle with decreased cutaneous sensation during reach to grasp?
TENS
Sensory discrimination
Kinesiotape
True or False: Bimanual intensive training had more impact on unimanual outcome measure?
False, it had less impact on unimanual outcome measure (Melbourne assessment)
True or False: Bimanual intensive training and constraint induced movement therapy have similar outcomes on bimanual assessment and participation measures.
True
True or False: Trunk restraint was demonstrated to reduce anterior trunk displacement during reaching
True
