Principles of Intervention (9/12b) Flashcards
Testing Movement Factors - Force
EX: manual muscle testing, rep max testing, dynamometer
Testing Movement Factors - Motion
EX: goniometer, joint integrity testing
Testing Movement Factors - Energy
EX: vital signs, questionnaire, performance
Testing Movement Factors - Motor Control
EX: testing motor planning, sensation, following commands
Testing Movement Factors - During Eval/Diagnosis/Prognosis
Should I intervene?
Yes → what interventions to use?
No → refer out?
The Intervention Principle
To change homeostatic mechanisms (status quo), we must change stress(es) on the system to stimulate responses in the system to reduce the problem/improve function
Interventions have a ___-___ relationship
Dose-response
Inadequate dose
inadequate or no response
Optimal dose
optimal response
Overdose
suboptimal/potentially harmful response
Why is patient education important?
We have to teach patients how to manage physical stress correctly
teach whether they need to increase or reduce physical stress
Therapeutic dose
Area of increased tolerance that produces change we want to see while avoiding side effects we want to avoid
Physical Stress Theory (PST)
changes in the relative level of physical stress cause a predictable adaptive response in all biological tissue
Body is able to sense mechanical stress and can translate into biological activity
Intervention principles (PST)
Goal is to disturb homeostasis in terms of physical stress, assuming a dose-response effect, to induce adaptation
Things to consider with interventions (PST)
Consider:
1) where a patient is coming from
2) how much change you expect
3) how long it should take to see measurable and meaningful change
To guide interventions (PST)
Goal Target Mechanism Time frame Dose Specificity Monitor effects
Goal (PST)
Function
Target (PST)
Tissue, organ, system
Mechanism (PST)
What way we plan to help patient, often cellular, subcellular
Time frame (PST)
Variable, when do we expect to see change
Dose (PST)
Intensity, frequency, duration
Specificity (PST)
How to guide exercises to be specific to goals
Monitor effects (PST)
How to measure effect, determine if we need to modify dose
Effectiveness of intervention depends on (PST)
How well limiting factors (health, personal, environmental) are identified in the examination and assessed in evaluation
How well intervention mechanisms address problems
Appropriate dose
Patient participation
