locomotor training Flashcards
What is the model of emerging rehab strategies described below?
- When the SC cannot repair itself
- Teaching new behaviors and skills
- Compensation-based intervention with aim to compensate for deficits
hierarchical model
What is the model of emerging rehab strategies described below?
- System is plastic and responsive
- Locomotor-specific activity
- Activity-based therapy with aim to restore neuromuscular system and gain recovery of pre-morbid function
Based on sensory input from periphery
heterarchical
(UMN or LMN) Which would benefit more from hierarchical and/or heterarchical models of rehab? Why?
UMN due to LMN requiring sensory input/feedback
What are important elements that need to be considered for locomotor training?
- Incomplete injury?
- Presence of spasticity and other UMN signs?
- Strong family/caregiver support
- Available transportation
- Motivation to recover
- Funding
(true/false) Locomotor training is just treadmill training.
FALSE!!!!
(step training, over ground assessment, community integration)
What is the optimal duration of step retraining per session?
20 minutes (4-5 minute bouts of stepping)
What is the #1 priority for locomotor training?
endurance
- speed
- BWS
- independence
What is the optimal duration of a session following a locomotor program model?
55-60 minutes of WB on a treadmill while initially increasing stepping
What is the optimal duration of a session following a locomotor program model if the session is 1.5 hours?
1 hour on treadmill with 30 minutes of off-overground activities
What are the higher-level structures of walking?
cortical –> determines the purpose of walking
What are the lower level structures of walking?
CPG and cerebellum
–> fine-tuned based on sensory feedback
–> generate motor patterns
What is the defining characteristic of forward progression?
controlled falling
What may limit ankle control during high-intensity stepping in gait training?
Stroke may limit ankle control
What may reduce walking speed during high-intensity stepping in gait training?
Hip / plantar flexor weakness may reduce walking speed
What can lead to collapse in stance during high-intensity stepping in gait training?
Quadriceps weakness may lead to collapse
What are the 4 major biomechanical subcomponents of gait?
Propulsion
Postural stability
Limb swing
Stance control
Human gait kinematics uses ____ to conserve energy
gravity
During split-belt treadmill training, a person with stroke who takes a longer step with the paretic leg and a shorter step with nonparetic leg during regular walking would need to walk on the TM with the paretic leg on the (slow/fast) belt.
slow belt
This will cause the person to take an even longer step with the paretic leg and an even shorter step with the nonparetic leg- it will enhance the asymmetry. Over time the person will correct the assymmtery by lengthening the nonparetic leg step and shortening the paretic leg step. When the belts are returned to the same speed the person will cont. this adjusted pattern thus improving their overall pattern. With improved step length asymetry.
(true/false) Results indicate split-belt treadmill training with the shorter step length on the fast belt has the potential to improve step length symmetry in individuals poststroke
true
What is most often used during gait training in those with PD?
cueing
Rhythmic auditory stimulation (RAS) is commonly used with what diagnosis?
PD
What type of training is described below?
- Challenging but safe
- Progressive and adaptable
- Interesting and meaningful
task-oriented training
