Non-Systems Flashcards
What will cause an increase in EMG signal?
increase in fatigue because more neural activity is required to maintain the same level of force production
Cluster Sampling
- larger samples that are divided into clusters
- clusters are randomly chosen and subjects are then chosen from the randomly chosen clusters
Stratified Sampling
Divides subjects into non-overlapping strata
Subjects randomly chosen from each stratum
Snowball Sampling
Researcher purposefully chooses a subject that can then identify other subjects
Ex. Subjects are parents of children with disabilities —> one set of parents may be able to connect the researcher with other parents
NON-randomized sampling strategy
What is a common adverse effect of antipsychotic drugs?
Tardive dyskinesia
- characterized by involuntary rhythmic movements of the mouth, tongue, jaw, trunk, or extremities
Systemic and Physiologic Effects of Thermal Modalities
Heat will result in INCREASED cardiac output, vasodilation, heart rate, respiratory rate, metabolic rate (think of a hot dog)
Heat will result in DECREASED muscle activity, blood pressure, blood to internal organs, blood flow to resting musle bc its going to the heated tissue, stroke volume
Systemic and Physiological Effects of Cryotherapy
Increased joint stiffness, pain threshold, and muscle activation
Decreased collagen extensibility, blood flow, capillary permeability, local metabolism, spasticity, and nerve conduction velocity
Effects of prolonged icing
15+ you’ll have decreased muscle activity
