MSK OM 2 Flashcards
PSYCHOMETRIC PROPERTIES: name + def of each
Sensitivity: ability of instrument to detect clinically significant improvement
- to correctly identify patients with disease
Specificity: ability of instrument to detect there are no changes or improvements
- to correctly identify people without disease
Validity: = extent to which instruments that are used in experiment measure exactly what you want them to measure
- Does your measure really tests what is it supposed to measure?
=> production of outcome that meets objective
Reliability: = extent to which outcomes are consistent when experiment repeated more than once
-If you measured same thing twice, would you get same results?
=> production of consistent, replicable outcomes
3 properties of reliability + def of each
Inter-rater: if there are 2 observes watching same behavior, scores should agree with each other
Internal consistency: within test, people should respond in consistent way to ALL of questions
Test-retest: if you give test to person more than once, they should get same score each time
MUSCLE STRENGTH OM: tests
Hand held dynamometer
Groin bar
Nord bord
HAND HELD DYNAMOMETER: description, advantages & disadvantages
D: - Objective measure
- Evaluate muscle strength
- Can be used in ≠ body positions & joint angles - Clinician applies force to limb of patient
A: Low cost
- Portable & Easy to use in practice
- Digitally records patient rehabilitation over time
- Motivational use for patients
- Can be used in all extremities & in ≠ body positions & angles
D: Tester strength
- Ideally same examiner performs each examination
GROIN BAR: description, advantages & disadvantages
D: Objective measure
- Assess hip & groin isometric muscle strength - Assess both limbs simultaneously
- Provides inter-limb asymmetry
A: Transportable
- Easy to use
- No need same examiner ( decrease variability)
- Digitally records patient rehabilitation over time - Enable measurement of both limbs simultaneously
- Provides asymmetries between legs
- Standardizedtestingposition
D: Expensive
- Specific for hip & groin strength (originally)
NORD BORD: description, advantages & disadvantages
D: Objective measure
- Assess eccentric & isometric hamstring strength
- Measure side-to-side imbalances
- It is used by many top professional sports
A: Transportable
- Easy to use
- No need same examiner
- Digitally records
- Enable measurement of both limbs simultaneously
- Provides asymmetries between limbs - Standardized testing position
D: Expensive
- Specific for knee flexor strength
PAIN OM test
Numerical rating scale
Wong-baker faces
McGill pain questionnaire
NUMERICAL RATING SCALE: advantages & disadvantages
A: - <1 min to complete
- Can be used internationally
- It can be administered verbally & in writing (accessible for more people)
D: - Evaluates only one aspect of pain- intensity - Evaluates pain experienced only in last
24 hours or “average pain intensity”
WONG BAKER FACES: advantages & disadvanatges
A: Easy for people to understand
- Fast
- Useful for children
- Useful if there is language barrier (also translated in many languages)
D: - Can be confusing-a child can think that he cant choose ‘’hurts worst’’ unless he is crying…
- Only one aspect of pain-intensity
- Pain experienced only in last 24 hours
McGill pain questionnaire: description advantages & disadvantages
D: Designed by Melzack (1975)
- Self-reporting measure
- Used to evaluate person experiencing pain
- Diagram of body shown to patient-mark where the pain is located on their body
- 20 sub-classes of descriptive words
- Pain rating index as words further down list score more points
- Higher pain score -> greater pain
A: Access to multidimensionality of pain - Can be used to monitor pain over time
D: Complex
Time consuming
KNEE FCT OM: test
Knee injury & OA Outcomes scores
Western Ontario & Mcmaster universities OA index
International knee documentation committee
KOOS: description, advantages & disadvantages
D: - Developed in 1990s
- Self-administered questionnaire
- Assess knee & associated problems
- 42 items
- Consists of 5 subscales; Pain, other Symptoms, Function in daily living (ADL), Function in sport & recreation (Sport/Rec) & knee related Quality of life (QOL)
- Can assess changes from week to week or over years following primary injury or OA (treatment, research studies)
A: Self-explanatory (fill out at waiting room,or electronic survey) - Can be used by ≠ populations (athletes, older adults)
- Covers both short-term & long-term consequences
- Can be used for long-term studies (cohort)
D: - Time consuming (issue if multiple instruments administered at same time)
WOMAC: description, advantages & disadvantages
D: Developed in 1982 at Western Ontario & McMaster Universities
- Self-administered questionnaire
- Evaluation of Hip & Knee Osteoarthritis
- 24 items divided into 3 subscales (pain, stiffness, & physical function) - Available in over 90 languages
A: Easy to use
- Multidimensional measure of pain, stiffness, & physical functional disability
- Disease-specific tool used for people with hip or knee OA
D: Length
- Lack of clarity in use & scoring (causes problems when combining &comparing results across ≠ trials)
IKDC: description, advantages & disadvantages
D: Development of IKDC began in 1987
- Measures symptoms, function, & sports activity in variety of knee conditions-overall function score
- Evaluates: pain, stiffness, swelling & giving- way of knee
A: 10 minutes for completion
- Knee-specific (not disease specific-can be used to measure symptoms, function, & sports activity for people with variety of knee disorders)
- Language that is easy to understand
- Suitable for all patient groups
D: Use of one total score (impossible to see in which domain patients have improved)
- Is not specific disease/disorder or knee instability
