Lecture 4-- Impairment Interventions Flashcards
Without correcting ________, continued functional training has the potential of delaying recovery or promoting faulty movement patterns
Impairments
Patients undergoing neurorehabilitation commonly present with disruption of _____ _____ from central pathways and reductions in muscle force production which is a direct result from what??
motor neurons
UMN lesion
Hemiparesis, hemiplegia?
weakness on one side of the body
Hemiplegia–paralysis
hemiparesis–weakness
Paraparesis, paraplegia?
Weakness or paralysis of both lower extremities
Tetra paresis, Tetraplegia, quadriparesis, quadriplegia ?
Weakness or paralysis of all four limbs
Prolonged periods of disuse and mobility result in?
diminished neural activity, atrophy and weakness
What are the benefits of strength training in patients with disorders of motor function?
- -increase in the production of maximal force due to changes in neural drive
- -Changes in muscle (strengthening)
- -Increases in connective tissue tensile strength and bone mineral density
- -Improved body composition
- -Improved functional performance and activity level
- -Improved sense of well-being and self-confidence
T/F the basic principles of strengthening exercise apply to neurorehabilitation?
TRUE
–Overload, specificity, cross training
What should early training focus on?
Isometric and eccentric contractions
–because muscle tension is better maintained c concentric contractions
Eccentric control produces _______ muscle force with _____ rates of motor unit discharge than concentric contractions.
greater, lower
more happens with less
When can a patient move from eccentric exercises to concentric?
When the patient can hold the position at midrange then have them slowly lower it. Once they can do these things they can move onto a concentric motion. Then when they can actively do it you can add weight.
A patient with a UMN lesion usually exhibits??
Spasticity, hypertonia
What is spasticity?
Motor disorder characterized by a velocity-dependent increase in muscle tone and increased resistance to stretch
What is chronic spasticity associated with?
contractors, abdominal posturing, deformity
T/F strength training and high resistance were contraindicated because they were viewed as likely to decrease spasticity and abdominal movement patterns?
FALSE
Increase spasticity, but no longer supported by scientific literature
A ______ muscle is generally a _____ muscle?
spastic, weak
(spasticity helps to give the muscle some rigidity, once that is gone the muscle is weak)
abnormal firing but very limited voluntary control
Gains in strength can be made through…..?
- progressive resistance exercises using free weights or fixed machines
- proprioceptive neuromuscular facilitation (PNF) uses manually resisted patterns to improve strength
- functional training using task-related practice
- Resistance provided by gravity, body weight
- Can add manual resistance to activities or movements
- Resistance of water during pool therapy
How do we maximize transfer of gains to functional skills?
combining strength and functional task-specific practice
What are the parameters in order to gain muscle strength?
Same as a healthy person
2-3 sets, 3-4 days per week, expect soreness (educate patient ahead of time)
What are the parameter for improving muscle endurance?
Resistance level that is tolerated for 15-20 reps
Multiple sets
3-4 days per week
How is fatigue defined?
Inability to contract muscle repeatedly over time
-exercise tolerance is reduced
What are the three sites that fatigue can arise from neuromuscular disease?
- CNS (MS, Guillain-barre, chronic fatigue, post-polio)
- Peripheral nerves or neuromuscular junction
- The muscle itself
What is the danger of exercise training in neuro patients?
Risk of acute exercise overdose producing exhaustion and possible injury
